Before NEWMAN, GAJARSA, and PROST, Circuit Judges.

Opinion for the court filed by Circuit Judge GAJARSA.        Dissenting opinion filed by
Circuit Judge NEWMAN.

GAJARSA, Circuit Judge.

      This is an interlocutory appeal by Cordis Corp. from a decision of the U.S. District

Court for the Western District of Oklahoma assuming supplemental subject matter

jurisdiction pursuant to 28 U.S.C. § 1367 over the foreign patent infringement claims of

Jan K. Voda, M.D. (“Voda”).     The district court established jurisdiction over Voda’s

original claims of U.S. patent infringement pursuant to § 1338. In a subsequent order,

the district court granted Voda leave to amend his complaint to add infringement claims

based on foreign patents. Voda’s amended complaint alleged infringement taking place

outside the United States in violation of patents issued by various foreign countries.
The district court found subject matter jurisdiction over the foreign patent claims

pursuant to the supplemental jurisdiction statute § 1367. Voda v. Cordis Corp., No. 03-

1512, slip op. at 2 (W.D. Okla. Aug. 2, 2004). The district court certified its order for

interlocutory review pursuant to § 1292(b). We agreed that the interlocutory appeal

“involve[s] a controlling question of law to which there is a substantial difference of

opinion and for which an immediate appeal may materially advance the ultimate

termination of the litigation” and thus, granted Voda’s petition for interlocutory appeal of

“whether the district court has supplemental subject matter jurisdiction over Dr. Voda's

five foreign patents.” Voda v. Cordis Corp., 122 Fed. App’x 515 (Fed. Cir. 2005). This

court has jurisdiction pursuant to § 1292(b) and (c).

       In Stein Associates, Inc. v. Heat & Control, Inc., 748 F.2d 653, 658 (Fed. Cir.

1984), this court held that U.S. district courts had no discretionary power to enjoin a

party from enforcing a foreign patent before a foreign tribunal. We stated unequivocally

that “the issues are not the same, one action involving United States patents and the

other involving British patents” and that “[o]nly a British court, applying British law, can

determine validity and infringement of British patents.” In this case, we are presented

with a different issue but one that raises similar concerns: whether a district court may

exercise supplemental jurisdiction pursuant to 28 U.S.C. § 1367 over infringement

claims based on foreign patents. For the reasons discussed below, we conclude that

the district court erred in granting leave to amend based on § 1367. Accordingly, we

vacate the order of the district court granting leave to amend and remand for further

proceedings consistent with this opinion.

                                             2
                                    I. BACKGROUND

       The plaintiff-appellee Voda is a resident of Oklahoma City, Oklahoma.            The

defendant-appellant Cordis is a U.S.-based entity incorporated in Florida. None of the

several foreign Cordis affiliates is a party to the present action, and we note that they

appear to be separate legal entities.1 These foreign affiliates have not been joined to

this action.2 To prevent confusion, we refer to the defendant-appellant as “Cordis U.S.”

       The patents at issue relate generally to guiding catheters for use in interventional

cardiology. The details of the technology are not essential here. Voda’s U.S. patents

stem from a common continuation-in-part (“CIP”) application filed in October 1992,

which provides the written description common to the three U.S. patents at issue in this

case: U.S. Patent Nos. 5,445,625 (the ’625 patent), 6,083,213 (the ’213 patent), and

6,475,195 (the ’195 patent).      The foreign patents issued from a common Patent

Cooperation Treaty (“PCT”) application. The PCT application designated the European

Patent Office (“EPO”) and Canada as recipients.           Voda’s EPO patent application

eventually generated European Pat. No. 0 568 624, British Pat. No. GB 568 624,

French Pat. No. FR568624, and German Pat. No. DE 69 23 20 95.                     The PCT

application also ultimately led to the issuance of Canadian Pat. No. CA 2,100,785.

       Voda sued Cordis U.S. in the United States District Court for the Western District

of Oklahoma alleging infringement of his three U.S. patents: claims 1-2 and 5-7 of the




       1
              For example, in addition to Cordis (U.S.), there are Cordis U.K., Ltd.,
Cordis S.A. (France), Cordis G.m.b.H. (Germany), Cordis S.p.A. (Italy), and Cordis
Benelux (Netherlands). All of the Cordis companies, both U.S. and foreign, are
members of the Johnson & Johnson family of companies.
      2
              Therefore, to the extent that the dissent suggests that the district court has
personal jurisdiction of the foreign Cordis entities, it is incorrect. See Dissent 1, 10, 19.
05-1238
                                             3
’625 patent, claims 1-5 of the ’213 patent, and claims 1-6 of the ’195 patent. Cordis

U.S. answered by asserting noninfringement and invalidity of the U.S. patents.

       Voda then moved to amend his complaint to add claims of infringement of the

European, British, Canadian, French, and German foreign patents. Voda’s amended

complaint alleges that “Cordis [U.S.] has commenced and continues acts of making,

selling, offering for sale and selling at least the XB guiding catheter, which is covered by

[the several foreign patents] without Dr. Voda’s authority.          Such acts constitute

infringement, under corresponding foreign law of [these several foreign patents].”

Cordis U.S. has admitted that “the XB catheters have been sold domestically and

internationally since 1994.    The XB catheters were manufactured in Miami Lakes,

Florida from 1993 to 2001 and have been manufactured in Juarez, Mexico since 2001.”

Voda’s amended complaint asks for damages, fees, and “such other and further relief

as this Court deems just and proper.” We resolve the jurisdictional issue based upon

those allegations, accepting them to be true.

       Cordis U.S. opposed Voda’s attempt to amend its complaint to add foreign patent

infringement claims on the basis that the district court lacked subject matter jurisdiction

over such claims. The parties briefed the court regarding its jurisdiction over foreign

patent infringement claims under 28 U.S.C. § 1367(a) and its discretion to exercise

supplemental jurisdiction under § 1367(c).       In a three-page order, the district court

analyzed two circuit court cases discussing supplemental jurisdiction over patent claims,

Mars, Inc. v. Kabushiki-Kaisha Nippon Conlux, 24 F.3d 1368 (Fed. Cir. 1994) (finding no

jurisdiction), and Ortman v. Stanray, 371 F.2d 154 (7th Cir. 1967) (affirming district

court’s denial of a motion to dismiss foreign patent infringement claims). The district



05-1238
                                             4
court determined that “[t]he allegations in the [proposed] amended complaint

demonstrate that this case is more akin to Ortman than to Mars” and thus, that “it would

have supplemental jurisdiction over the foreign patent[] claim[s].” Voda v. Cordis, No.

CIV-03-1512-L, slip op. at 2 (August 2, 2004). Therefore, the district court granted

Voda’s motion to file his amended complaint. Id.

       Cordis U.S. appeals, and in light of this appeal, the proceedings with respect to

the foreign patent infringement claims have been stayed.3 The record indicates that an

answer to the amended complaint has not been filed and that discovery has not been

taken on the foreign claims. While the record therefore does not establish the defenses

Cordis U.S. would raise, Cordis U.S. represents on appeal that it would raise invalidity

of the foreign patents as a defense.

       A proper exercise of subject matter jurisdiction pursuant to § 1367 requires both

the presence of jurisdiction under subsection (a) and an appropriate decision to

exercise that jurisdiction under subsection (c). For the reasons discussed below, we

conclude that the district court erred under subsection (c).

                              II. STANDARD OF REVIEW

       The existence of supplemental jurisdiction over foreign patent claims based on

claims of U.S. patent infringement is a question unique to U.S. patent law, and thus, we

apply the law of our circuit rather than that of the regional circuit. Mars, 24 F.3d at 1371

(“The issue whether the district court had jurisdiction to hear Mars’ claim of Japanese

patent infringement is of importance to the development of the patent law and is clearly

       3
              It appears that the district court conducted a jury trial on Voda’s U.S.
patent infringement claims, and that the jury found in favor of Voda on May 25, 2006.
(Jury Verdict, May 25, 2006.) None of the parties or amicus curiae informed the court of
this event, and we do not consider it necessary to our ultimate holding.

a matter that falls within the exclusive subject matter responsibility of this court.”

(quotation marks and citations omitted)); see Lab. Corp. of Am. Holdings v. Chiron

Corp., 384 F.3d 1326, 1330 (Fed. Cir. 2004) (applying Federal Circuit law because we

“apply the law of the regional circuit . . . unless the issue pertains to or is unique to

patent law, in which case we will apply our own law to both substantive and procedural

issues intimately involved in the substance of enforcement of the patent right” (quotation

marks omitted)); cf. Unitherm Food Sys. v. Swift-Eckrich, Inc., 126 S. Ct. 980, 984

(2006) (recognizing that Federal Circuit is bound to apply procedural law of regional

circuit in case where issue did not pertain uniquely to patent law).

       We have noted that “[t]his Court . . . reviews jurisdiction, a question of law, de

novo.” Dehne v. United States, 970 F.2d 890, 892 (Fed. Cir. 1992) (citation omitted);

see also Elder v. Holloway, 510 U.S. 510, 516 (1994) (“[Q]uestion[s] of law . . . must be

resolved de novo on appeal.”). “A party seeking the exercise of jurisdiction in its favor

bears the burden of establishing that such jurisdiction exists.” Mars, 24 F.3d at 1372

(citing KVOS, Inc. v. Associated Press, 299 U.S. 269, 278 (1936)); cf. DaimlerChrysler

Corp. v. Cuno, 126 S. Ct. 1854, 1861 (2006) (“[P]arties . . . asserting federal

jurisdiction[] carry the burden of establishing their standing under Article III.”). Here,

Voda must carry this burden.

                                    III. DISCUSSION

       The Supreme Court has stated many times that the “district courts of the United

States . . . are ‘courts of limited jurisdiction. They possess only that power authorized

by Constitution and statute.’” Exxon Mobil Corp. v. Allapattah Servs., 545 U.S. 546, ---,

125 S. Ct. 2611, 2616-17 (2005) (quoting Kokkonen v. Guardian Life Ins. Co. of Am.,



05-1238
                                             6
511 U.S. 375, 377 (1994)). In addition, “district courts may be obligated not to decide

state law claims (or to stay their adjudication) where one of the abstention doctrines

articulated by [the Supreme] Court applies.” City of Chicago v. Int’l Coll. of Surgeons,

522 U.S. 156, 174 (1997).

       In this case, the parties do not dispute that the Constitution may authorize district

courts to hear infringement claims based on foreign patents. See U.S. Const. art. III,

§ 2 (“[J]udicial Power shall extend . . . to Controversies . . . between a State, or the

Citizens thereof, and foreign States, Citizens or Subjects.”). Rather, the critical disputed

issue is whether there is any statutory basis for such subject matter jurisdiction.4

A.     Asserted Statutory Basis

       Voda asserts that the district court has supplemental jurisdiction under 28 U.S.C.

§ 1367 of his foreign patent infringement claims.5 The Supreme Court has noted that

the statute “is a broad grant of supplemental jurisdiction over other claims within the

same case or controversy, as long as the action is one in which the district courts would

have original jurisdiction.” Exxon, 125 S. Ct. at 2620. “The presence of other claims in

       4
                The dissent broadly states that no court has held “that it had no power or
authority to receive the foreign issue.” Dissent 6. Yet, the first case cited by the dissent
to support this broad proposition, written by the dissenting author, held that there was
no jurisdiction and alternatively, affirmed the dismissal based on forum non conveniens.
See Bonzel v. Pfizer, Inc., 439 F.3d 1358, 1362-65 (Fed. Cir. 2006); see also Mars, 24
F.3d at 1373-75 (holding that no federal question or supplemental jurisdiction existed).
         5
                Voda has asserted no other statutory basis for subject matter jurisdiction.
Therefore, the dissent’s assertion that “judicial authority to determine and apply foreign
law does not require that the foreign issue is supplemental to a domestic issue,” Dissent
8, is irrelevant in this case. Similarly, the cases cited by the dissent that rely on federal
question jurisdiction or diversity jurisdiction are inapposite. See, e.g., Uebersee Finanz-
Korporation, A.G. v. McGrath, 343 U.S. 205, 206 (1952) (claim under U.S. law, Trading
with the Enemy Act of 1917); Cambridge Literary Properties, Ltd. v. W. Goebel
Porzellanfabrik G.m.b.H. & Co. Kg., 295 F.3d 59, 61-63 (1st Cir. 2002) (claim under
U.S. copyright law); Curley v. AMR Corp., 153 F.3d 5, 12 (2d Cir. 1998) (diversity
jurisdiction); see also Dissent 3-5.
05-1238
                                             7
the complaint, over which the district court may lack original jurisdiction, is of no

moment.” Id.; cf. Marshall v. Marshall, 126 S. Ct. 1735, 1749 (2006) (stating in diversity

context that jurisdiction “is determined by the law of the court’s creation and cannot be

defeated by the extraterritorial operation of a [state] statute . . . , even though it created

the right of action” (quotation marks and citations omitted)).

       The Supreme Court has also noted that § 1367 both “authorize[s] the district

courts to exercise supplemental jurisdiction” and “confirms the discretionary nature of

supplemental jurisdiction.” Chicago, 522 U.S. at 172-73. Therefore, to allow Voda to

amend his complaint to add infringement claims based on foreign patents using § 1367

supplemental jurisdiction, we must evaluate (1) whether § 1367(a) authorizes such

supplemental jurisdiction and (2) whether the district court’s exercise of such

supplemental jurisdiction was within its § 1367(c) discretion.

       1.      Authorization

       Section 1367(a) provides the statutory authority for district courts to exercise

supplemental jurisdiction over certain claims outside their original jurisdiction.

            Except as provided in subsections (b) and (c) or as expressly
            provided otherwise by Federal statute, in any civil action of which
            the district courts have original jurisdiction, the district courts shall
            have supplemental jurisdiction over all other claims that are so
            related to claims in the action within such original jurisdiction that
            they form part of the same case or controversy under Article III of
            the United States Constitution. Such supplemental jurisdiction shall
            include claims that involve the joinder or intervention of additional
            parties.

28 U.S.C. § 1367(a). This language reveals four limits on the reach of § 1367(a).

       First, § 1367(a) does not authorize supplemental jurisdiction where “expressly

provided otherwise by Federal statute.” In this case, none of the parties or the amicus



05-1238
                                               8
curiae cite any statute, and we have found none, that expressly strips federal courts of

supplemental jurisdiction of claims arising under either foreign patents or foreign laws.

       Second, § 1367(a) lists subsection (b) as an exception. Subsection (b) pertains

to “any civil action of which the district courts have original jurisdiction founded solely

on” diversity and thus, is not relevant here.

       Third, § 1367(a) also lists subsection (c) as an exception.            We discuss

subsection (c), which enumerates the circumstances under which the “district courts

may decline to exercise supplemental jurisdiction,” in infra Part III.A.2.

       Fourth, § 1367(a) authorizes supplemental jurisdiction only over claims that are

“so related to claims in the action within such original jurisdiction that they form part of

the same case or controversy under Article III of the United States Constitution.” This

statutory “case or controversy” language extends to the limits of Article III. See, e.g.,

Jones v. Ford Motor Credit Co., 358 F.3d 205, 212 n.5 (2d Cir. 2004); Baer v. First

Options of Chicago, Inc., 72 F.3d 1294, 1299 (7th Cir. 1995).

       In this case, it is undisputed that the district court has original federal question

jurisdiction over Voda’s U.S. patent infringement claims. In addition, § 1367(a) appears

to authorize supplemental jurisdiction over foreign law claims in certain limited

circumstances. Specifically, § 1367(a) provides the statutory authority for federal courts

to exercise supplemental jurisdiction over claims that are outside the limited original

jurisdiction of federal district courts, including those within the general jurisdiction of

state courts. Therefore, because the “inherent powers” of state courts “permit them to

entertain transitory causes of action arising under the laws of foreign sovereigns,” Tafflin

v. Levitt, 493 U.S. 455, 470 (1990) (Scalia, J., concurring) (citing McKenna v. Fisk, 42



05-1238
                                                9
U.S. (1 How.) 241, 247-249 (1843)), § 1367 supplemental jurisdiction appears to include

foreign law claims. See also Printz v. United States, 521 U.S. 898, 907 (1997) (“[U]nlike

legislatures and executives, [courts] applied the law of other sovereigns all the time.”).

Therefore, the § 1367(a) issue we discuss here is whether Voda’s claims of foreign

patent infringement “form part of the same case or controversy under Article III.”

               a.     “Common nucleus of operative fact”

         The Supreme Court has interpreted the statutory requirement of § 1367(a) that

foreign claims be “so related to claims in the action within such original jurisdiction that

they form part of the same case or controversy” as Congress’s codification of the

Court’s

            principles of pendent and ancillary jurisdiction by which the federal
            courts’ original jurisdiction over federal questions carries with it
            jurisdiction over state law claims that “derive from a common
            nucleus of operative fact,” such that “the relationship between [the
            federal] claim and the state claim permits the conclusion that the
            entire action before the court comprises but one constitutional
            ‘case.’”

Chicago, 522 U.S. at 164-65 (quoting United Mine Workers of Am. v. Gibbs, 383 U.S.

715, 725 (1966)) (additional citations omitted) (emphasis added); see also 13B Wright,

Miller, Cooper & Freer, Federal Practice & Procedure § 3567.1, at n.42 (2d ed. Supp.

2005).

         With regard to the relationship between foreign and U.S. patent infringement

claims, we stated in Stein that “the issues are not the same” where “one action

involv[es] United States patents and the other involv[es] British patents.” 748 F.2d at

658. Mars, 24 F.3d 1368, however, is the first and only case of this court that expressly

evaluates whether supplemental jurisdiction under § 1367(a) extends to infringement



05-1238
                                             10
claims based on foreign patents. In Mars, we applied the “common nucleus of operative

fact” rubric to determine whether § 1367(a) authorized supplemental jurisdiction over an

infringement claim based on a Japanese patent. We held that “the district court erred in

assuming that it had ‘power’ to hear the Japanese patent infringement claim under

section 1367(a).”     Id. at 1375.    Based on the facts alleged in the complaint, we

reasoned:

            We conclude that the foreign patent infringement claim at issue
            here is not so related to the U.S. patent infringement claim that the
            claims form part of the same case or controversy and would thus
            ordinarily be expected to be tried in one proceeding. [1] The
            respective patents are different, [2] the accused devices are
            different, [3] the alleged acts are different, and [4] the governing
            laws are different. The assertion of supplemental jurisdiction over
            the Japanese infringement claim would in effect result in the trial
            court having to conduct two separate trials at one time.

Id. Regarding the first three factors, we noted (1) that in the U.S. patent “[a]ll three

claims are method claims directed to the electronic examination and identification of

coins” whereas “[i]n contrast, the sole claim of the Japanese Patent . . . is an apparatus

claim that does not literally contain the limitations of [the asserted] claims . . . of the U.S.

patent”; (2) that the claims of U.S. and Japanese patent infringement focused on

different devices and that “the range of accused devices in Japan is much broader than

in the United States”; and (3) that although Mars charged the defendant with acts of

both direct and induced infringement of its U.S. patent, it charged the defendant with

only direct infringement of the Japanese patent. Id.

       In this case, Voda does not dispute the assertion of Cordis U.S. that the

“governing laws in each of the foreign courts differ in important ways.” The parties

dispute whether the patents are different. Cordis U.S. asserts that the patents differ



05-1238
                                              11
materially, while Voda asserts that they differ only in slight respects.6 With respect to

the other factors, however, there appear to be more commonalities than in Mars.

Voda’s amended complaint identifies Cordis U.S.’s XB guiding catheter as the accused

device for the domestic and foreign infringement claims. Voda also alleges the same

type of direct infringement, i.e., making, offering for sale, and selling, for all infringement

claims.

       In addition, it is important to note that Mars does not supplant the “common

nucleus of operative fact” test established by the Supreme Court in Gibbs and codified

by Congress in § 1367(a). Mars simply listed four differences between the claims in

that particular case that were sufficient for finding no “common nucleus of operative

fact.” As such, while providing precedential guidance, Mars did not establish either an

exhaustive list of the factors district courts may consider under § 1367(a) or the

necessary conditions for a finding of no supplemental jurisdiction.

       The district court failed to articulate any such analysis. The district court correctly

observed that Mars did not establish a per se rule preventing U.S. courts from asserting

supplemental jurisdiction to adjudicate foreign patents, but then summarily concluded

that the “allegations in the amended complaint demonstrate that this case [wa]s more

akin to Ortman[, 371 F.2d 154 (7th Cir. 1967),] than to Mars.               Based on those

allegations, the [district] court [found] that it would have supplemental jurisdiction over

the foreign patents claims.” Voda, slip op. at 2. Even if we agreed that this case were



       6
              Therefore, none of the parties would agree with the dissent’s conclusions
that “the specifications are the same” or that the patents “are identical.” Dissent 10, 13.
Moreover, it is unclear how the dissent arrives at these conclusions when the French
and German patents are in different languages, and the record on appeal provides no
translations.
05-1238
                                              12
“more akin” to Ortman than Mars, that does not answer the legal question of whether

there is a “common nucleus of operative fact” in this case.

       Here, the district court did not articulate any findings regarding the Mars factors.7

Moreover, although the determination of foreign law is a question of law, we as an

appellate court cannot take any expert testimony to determine the extent of the

differences in the governing laws. See Fed. R. Civ. P. 44.1 (governing determination of

foreign law).        Since the scope of a foreign patent depends on foreign law, such

testimony would also inform a comparison of the patents themselves.                 Therefore,

because we hold in infra Part III.A.2 that the district court abused its discretion under

§ 1367(c), we deem it to be the more prudent course not to decide this “common

nucleus of operative fact” question in the first instance.

                b.       “Ordinarily be expected to try them all in one judicial proceeding”

       Seizing on the Supreme Court’s language in Gibbs, one of the amicus curiae

asserts that in determining the existence of “the same case or controversy” under

§ 1367(a), we must examine not only whether there is a “common nucleus of operative

fact,” but also whether a district court would “ordinarily be expected to try [domestic and

foreign patent infringement claims] all in one judicial proceeding.”

       While courts generally focus on the phrase “common nucleus of operative fact,”

there is an ambiguity in Gibbs, in which the Supreme Court stated:




       7
              The Supreme Court has stated that “where issues arise as to jurisdiction
or venue, discovery is available to ascertain the facts bearing on such issues.”
Oppenheimer Fund, Inc. v. Sanders, 437 U.S. 340, 351 n.13 (1978) (citation omitted).
The dissent cites no authority to the contrary to support its position that it is “unfair” and
“inappropriate to criticize the judge for not making findings or taking evidence at the
pleading stage.” Dissent 11.
05-1238
                                                13
          The federal claim must have substance sufficient to confer subject
          matter jurisdiction on the court. The state and federal claims must
          derive from a common nucleus of operative fact. But if, considered
          without regard to their federal or state character, a plaintiff’s claims
          are such that he would ordinarily be expected to try them all in one
          judicial proceeding, then, assuming substantiality of the federal
          issues, there is power in federal courts to hear the whole.

383 U.S. at 725 (citation and footnote omitted) (emphasis added). From the text of

Gibbs, it is therefore unclear how the phrases “common nucleus of operative fact” and

“ordinarily be expected to try them all in one judicial proceeding” relate.

       The Court’s subsequent use of the Gibbs language indicates that the phrases

could represent two separate and necessary tests or that the phrase “ordinarily be

expected” is irrelevant. Compare Exxon, 125 S. Ct. at 2632 (Ginsburg, J., dissenting)

(“‘[T]here is power in federal courts to hear the whole,’ the Court said, when the state

and federal claims ‘derive from a common nucleus of operative fact’ and are so linked

that the plaintiff ‘would ordinarily be expected to try them all in one judicial proceeding.’”

(emphasis added)), and Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 349 (1988)

(“The Court stated that a federal court has jurisdiction over an entire action, including

state-law claims, whenever the federal-law claims and state-law claims in the case

‘derive from a common nucleus of operative fact’ and are ‘such that [a plaintiff] would

ordinarily be expected to try them all in one judicial proceeding.’” (emphasis added)),

with Chicago, 522 U.S. at 165 (“[T]he state and federal claims ‘derive from a common

nucleus of operative fact,’ . . . . That is all the statute requires to establish supplemental

jurisdiction.” (citation omitted) (emphasis added)).

       Similarly, this court’s use of the Gibbs language indicates that the phrases could

represent two separate and necessary tests or that the phrase “ordinarily be expected



05-1238
                                             14
to try them all in one judicial proceeding” merely informs the “common nucleus of

operative fact” analysis. Compare Stark v. Advanced Magnetics, Inc., 29 F.3d 1570,

1578 (Fed. Cir. 1994) (finding § 1367 requirements met where “there is a substantial

federal claim; the federal and state claims derive from common operative facts; and the

plaintiff would normally expect to try all of the claims in a single proceeding”), with

Highway Equip. Co., Inc. v. FECO, Ltd., 469 F.3d 1027, 1037-38 (Fed. Cir. 2006) (“For

this relatedness requirement to be satisfied, ‘[t]he state and federal claims must derive

from a common nucleus of operative fact’ such that they would ordinarily be expected to

be tried in one proceeding.” (citation omitted)), and Mars, 24 F.3d at 1374 (“The Court

further explained that the requisite relatedness between the federal and non-federal

claims exists for jurisdictional purposes when the claims derive from a ‘common nucleus

of operative fact,’ and as such, would ordinarily be expected to be tried in one

proceeding.”).

      If the phrase “ordinarily be expected to try them all in one judicial proceeding”

does play a role in the scope of § 1367(a) authorization via Gibbs, district courts may be

unable to exercise supplemental jurisdiction over claims based on foreign patents if the

norm is that patent claims are adjudicated by the courts within the jurisdiction where

such patents are created. Neither the Supreme Court nor this court, however, has

addressed whether the phrase “ordinarily be expected to try them all in one judicial

proceeding” constitutes an independent requirement under the “same case or

controversy requirement” of § 1367(a). Because the district court abused its discretion

under § 1367(c), however, we need only state in this case that none of the briefs have

persuaded us to hold that such an additional requirement exists.



05-1238
                                           15
       Accordingly, we refrain from deciding whether Voda’s foreign patent infringement

claims fall within the scope of the “same case or controversy” requirement of § 1367(a).

       2.      Discretion

       Section 1367 “reaffirms that the exercise of supplemental jurisdiction is within the

discretion of the district court.” Mars, 24 F.3d at 1374; see also Chicago, 522 U.S. at

172 (stating that supplemental jurisdiction statute codifies principle “that pendent

jurisdiction ‘is a doctrine of discretion, not of plaintiff’s right,’ and that district courts can

decline to exercise jurisdiction over pendent claims for a number of valid reasons”

(quoting Gibbs, 383 U.S. at 726)).           A district court’s discretion, however, is not

unfettered, and we review the district court’s decision not to decline supplemental

jurisdiction under 28 U.S.C. § 1367(c) under an abuse of discretion standard. Mars, 24

F.3d at 1375 n.4; see also Marcus v. AT&T Corp., 138 F.3d 46, 57 (2d Cir. 1998) (“We

review the decision of the district court to exercise supplemental jurisdiction over state

law claims for an abuse of discretion.”). We address the limits of that discretion here

and conclude that the district court’s exercise of supplemental jurisdiction over Voda’s

foreign patent infringement claims is independently limited by subsection (c).

       Section 1367(c) provides:

            The district courts may decline to exercise supplemental jurisdiction
            over a claim under subsection (a) if—
               (1) the claim raises a novel or complex issue of State law,
               (2) the claim substantially predominates over the claim or claims
                   over which the district court has original jurisdiction,
               (3) the district court has dismissed all claims over which it has
                   original jurisdiction, or
               (4) in exceptional circumstances, there are other compelling
                   reasons for declining jurisdiction.




05-1238
                                               16
28 U.S.C. § 1367(c). The Supreme Court has noted that the “statute thereby reflects

the understanding that, when deciding whether to exercise supplemental jurisdiction, ‘a

federal court should consider and weigh in each case, and at every stage of the

litigation, the values of judicial economy, convenience, fairness, and comity.’” Chicago,

522 U.S. at 173 (citation omitted).

       Voda asserts that such considerations “have nothing to do with, the certified

question concerning existence of subject-matter jurisdiction.” We disagree. The text of

§ 1367(a) indicates § 1367(c) constitutes an express statutory exception to the

authorization of jurisdiction granted by § 1367(a). In this case, Cordis U.S. asserted

that the district court should exercise its discretion to decline supplemental jurisdiction of

Voda’s foreign patent claims at the end of its opposition to Voda’s motion to amend the

complaint. The district court’s order contained no § 1367(c) analysis. We find that

considerations of comity, judicial economy, convenience, fairness, and other

exceptional circumstances constitute compelling reasons to decline jurisdiction under

§ 1367(c) in this case and therefore, hold that the district court abused its discretion by

assuming jurisdiction.

              a.     Treaties as the “supreme law of the land”

       Article VI of the Constitution proclaims that “all treaties made, or which shall be

made, under the authority of the United States, shall be the supreme law of the land.”

U.S. Const. art. VI, cl.2. The Supreme Court has accordingly stated that “a treaty

ratified by the United States is not only the law of this land, see U.S. Const., Art. II, § 2,

but also an agreement among sovereign powers.” El Al Isr. Airlines, Ltd. v. Tsui Yuan

Tseng, 525 U.S. 155, 167 (1999) (citation omitted).

                                             17
       The United States entered into Articles 13 through 30 of the Paris Convention for

the Protection of Industrial Property (“Paris Convention”) on September 5, 1970 and

Articles 1 through 12 of the Paris Convention on August 25, 1973. Paris Convention,

art. 13-30, 21 U.S.T. 1583; id., art. 1-12, 24 U.S.T. 2140. Article 4bis of the Paris

Convention states that U.S. patents “shall be independent of patents obtained for the

same invention in other countries” and that the “foregoing provision is to be understood

in an unrestricted sense, . . . both as regards the grounds for nullity and forfeiture.” In

addition, Article 2(3) of the Paris Convention states that the “provisions of the laws of

each of the countries of the Union relating to judicial and administrative procedure and

to jurisdiction, . . . which may be required by the laws on industrial property are

expressly reserved.” The Paris Convention thus clearly expresses the independence of

each country’s sovereign patent systems and their systems for adjudicating those

patents. Nothing in the Paris Convention contemplates nor allows one jurisdiction to

adjudicate the patents of another, and as such, our courts should not determine the

validity and infringement of foreign patents. Accordingly, while the Paris Convention

contains no express jurisdictional-stripping statute, we relied on it in Stein to hold that

“[o]nly a British court, applying British law, can determine validity and infringement of

British patents.” 748 F.2d at 658.

       Subsequently, the United States adopted the Patent Cooperation Treaty (“PCT”)

on January 24, 1978. Patent Cooperation Treaty, 28 U.S.T. 7645. As with the Paris

Convention, the text of the PCT maintains the independence of each country’s patents.

Article 27(5) states: “Nothing in this Treaty and the Regulations is intended to be




05-1238
                                            18
construed as prescribing anything that would limit the freedom of each Contracting

State to prescribe such substantive conditions of patentability as it desires.”

       On January 1, 1995, the United States joined the World Trade Organization by

entering the Marrakesh Agreement Establishing the World Trade Organization, which

through Article II § 2 binds all of its members to the Agreement on Trade-Related

Aspects of Intellectual Property Rights (“TRIPS”). 1867 U.N.T.S. 154, 33 I.L.M. 1144

(Apr. 15, 1994). The Agreement on TRIPS contains several provisions regarding the

enforcement of patents. Article 41 § 1 of the Agreement on TRIPS specifies that each

country “shall ensure that enforcement procedures as specified in this Part are available

under their law so as to permit effective action against any act of infringement of

intellectual property rights.” In addition, § 4 states that “[p]arties to a proceeding shall

have an opportunity for review by a judicial authority of final administrative decisions

and, subject to jurisdictional provisions in a Member’s law concerning the importance of

a case,” and § 5 states “[i]t is understood that this Part does not . . . affect the capacity

of Members to enforce their law in general.” See also id., art. 41-49. Like the Paris

Convention, nothing in the PCT or the Agreement on TRIPS contemplates or allows one

jurisdiction to adjudicate patents of another.8     Canada, France, Germany, and the

United Kingdom, which are the foreign sovereigns concerned in this case, are parties to

       8
              While the European Patent Convention (“EPC”) states nothing of our
government’s intent because the United States is not a party, it may inform us on how
other sovereigns treat foreign patent adjudication. Regarding claims “to the right to the
grant of a European patent,” the EPC has enumerated rules specifying courts of
exclusive jurisdiction. European Patent Convention, Protocol on Recognition, art. 1-8,
October 5, 1973. None of the treaties entered into by the United States contain such
language. Moreover, while there have been working parties and draft agreements and
statutes, even the members of the EPC have not yet agreed on a centralized European
patent court. See European Patent Office, “Legislative Initiatives in European Patent
Law” (July 26, 2006), available at http://patlaw-reform.european-patent-office.org/epla/.

the PCT and the Paris Convention and Members of the World Trade Organization”

(2006), available at http://www.wipo.int/pct/en/texts/pdf/pct_paris_wto.pdf.

       Voda asserts and one of the amicus curiae briefs suggests that these

international treaties evince a trend of harmonization of patent law and thus, that

allowing the exercise of supplemental jurisdiction over Voda’s foreign patent

infringement claims furthers the harmonization goals underlying the treaties.

Regardless of the strength of the harmonization trend, however, we as the U.S. judiciary

should not unilaterally decide either for our government or for other foreign sovereigns

that our courts will become the adjudicating body for any foreign patent with a U.S.

equivalent “so related” to form “the same case or controversy.”        Cf. F. Hoffman-La

Roche Ltd. v. Empagran S.A., 542 U.S. 155, 166-67 (2004) (finding “no convincing

justification” for providing such subject matter jurisdiction in antitrust context).

Permitting our district courts to exercise jurisdiction over infringement claims based on

foreign patents in this case would require us to define the legal boundaries of a property

right granted by another sovereign and then determine whether there has been a

trespass to that right.

       Based on the international treaties that the United States has joined and ratified

as the “supreme law of the land,” a district court’s exercise of supplemental jurisdiction

could undermine the obligations of the United States under such treaties, which




05-1238
                                            20
therefore constitute an exceptional circumstance to decline jurisdiction under

§ 1367(c)(4). Accordingly, we must scrutinize such an exercise with caution.9

             b.     Comity and relations between sovereigns

      “Comity refers to the spirit of cooperation in which a domestic tribunal

approaches the resolution of cases touching the laws and interests of other sovereign

states.” Société Nationale Industrielle Aérospatiale v. U.S. Dist. Court for the S.D. of

Iowa, 482 U.S. 522, 543 n.27 (1987).

          Comity, in the legal sense, is neither a matter of absolute
          obligation, on the one hand, nor of mere courtesy and good will,
          upon the other. But it is the recognition which one nation allows
          within its territory to the legislative, executive or judicial acts of
          another nation, having due regard both to international duty and
          convenience, and to the rights of its own citizens or of other
          persons who are under the protection of its laws.

Id. (quoting Hilton v. Guyot, 159 U.S. 113, 163-64 (1895)) (quotation marks omitted)

(emphasis added). Courts must also bear in mind that “whatever laws are carried into

execution, within the limits of any government, are considered as having the same

effect every where, so far as they do not occasion a prejudice to the rights of the other

governments, or their citizens.” Id. (quoting Emory v. Grenough, 3 U.S. (3 Dall.) 369,

370 (1797) (quotation marks and citation omitted)) (emphasis added). Société provides

us with these considerations to guide our determination of whether an exercise of

                In addition, even assuming that Cordis U.S. is responsible for
manufacturing the allegedly infringing devices in Juarez, Mexico, and selling them in
foreign countries, the dissent’s assertion that we could adjudicate a foreign patent
infringement action and enforce the judgment against Cordis U.S. for its foreign
manufacturing and foreign sales, Dissent 1 n.1, would be an end-run around the
territorial limits of 35 U.S.C. § 271. See Dowagiac, 235 U.S. at 650 (“The right
conferred by a patent under our law is confined to the United States and its territories.”
(citation omitted)); cf. AT&T Corp. v. Microsoft Corp., 414 F.3d 1366 (Fed. Cir. 2005),
cert. granted, 127 S. Ct. 467 (2006).
05-1238
                                           21
comity supports extending or declining jurisdiction over the foreign patent infringement

claims at issue here. See id. at 543-44 (stating that international comity concept in

evidence-gathering context requires particularized analysis of facts and sovereign

interests).

       In this case, these considerations of comity do not support the district court’s

exercise of supplemental jurisdiction over Voda’s foreign patent infringement claims.

First, Voda has not identified any international duty, and we have found none, that

would require our judicial system to adjudicate foreign patent infringement claims. As

discussed supra Part III.A.2.a, while the United States has entered into the Paris

Convention, the PCT, and the Agreement on TRIPS, nothing in those treaties

contemplates or allows one jurisdiction to adjudicate the patents of another. Second, as

discussed infra Part III.A.2.d, Voda has not shown that it would be more convenient for

our courts to assume the supplemental jurisdiction at issue. Third, with respect to the

rights of our citizens, Voda has not shown that foreign courts will inadequately protect

his foreign patent rights.   Indeed, we see no reason why American courts should

supplant British, Canadian, French, or German courts in interpreting and enforcing

British, Canadian, European, French, or German patents. Cf. Empagran, 542 U.S. at

165 (finding no reason to allow “American [antitrust] law [to] supplant, for example,

Canada’s or Great Britain’s or Japan’s own determination about how best to protect

Canadian or British or Japanese customers from anticompetitive conduct”).

       Fourth, assuming jurisdiction over Voda’s foreign patent infringement claims

could prejudice the rights of the foreign governments. None of the parties or amicus

curiae have demonstrated that the British, Canadian, French, or German governments



05-1238
                                          22
are willing to have our courts exercise jurisdiction over infringement claims based on

their patents. Cf. 28 U.S.C. § 1338(a) (granting federal courts exclusive jurisdiction of

claims relating to U.S. patents).

       In addition, the local action doctrine informs us that exercising supplemental

jurisdiction in this case appears to violate our own norms of what sovereigns ordinarily

expect. Courts derived the local action doctrine from the distinction between local and

transitory actions beginning with Livingston v. Jefferson, written by Justice John

Marshall riding Circuit. 15 F. Cas. 660 (C.C.D. Va. 1811). In Livingston, the plaintiff

sued in a Virginia court for trespass to land located in Louisiana. The court dismissed

the action, holding that it could be brought only in a Louisiana court. The Supreme

Court subsequently held that “an action for trespass upon land, like an action to recover

the title or the possession of the land itself, is a local action, and can only be brought

within the State in which the land lies.” Ellenwood v. Marietta Chair Co., 158 U.S. 105,

107 (1895). The Court concluded that a federal court sitting in another state had no

jurisdiction to hear the trespass claim. Id. In short, the local action doctrine served to

prevent courts from adjudicating claims for trespass or title to real property.

       The territorial limits of the rights granted by patents are similar to those conferred

by land grants. A patent right is limited by the metes and bounds of the jurisdictional

territory that granted the right to exclude. See Dowagiac Mfg. Co. v. Minn. Moline Plow

Co., 235 U.S. 641, 650 (1915) (“The right conferred by a patent under our law is

confined to the United States and its territories.” (citation omitted)); NTP, Inc. v.

Research In Motion, Ltd., 418 F.3d 1282, 1313 (Fed. Cir. 2005) (“The territorial reach of

section 271 is limited. Section 271(a) is only actionable against patent infringement that



05-1238
                                             23
occurs within the United States.” (citations omitted)).       Therefore, a patent right to

exclude only arises from the legal right granted and recognized by the sovereign within

whose territory the right is located. It would be incongruent to allow the sovereign

power of one to be infringed or limited by another sovereign’s extension of its

jurisdiction.   Therefore, while our Patent Act declares that “patents shall have the

attributes of personal property,” 35 U.S.C. § 261, and not real property, the local action

doctrine constitutes an informative doctrine counseling us that exercising supplemental

jurisdiction over Voda’s foreign patent claims could prejudice the rights of the foreign

governments.

       Therefore, the four considerations enunciated by the Supreme Court in Société

demonstrate that extending our jurisdiction through § 1367(a) in this case could

undermine “the spirit of cooperation” underlying the comity doctrine.          Because the

purpose underlying comity is not furthered and potentially hindered in this case,

adjudication of Voda’s foreign patent infringement claims should be left to the

sovereigns that create the property rights in the first instance.

       In addition, as a rule of statutory construction, the Supreme Court “ordinarily

construes ambiguous statutes to avoid unreasonable interference with the sovereign

authority of other nations.” Empagran, 542 U.S. at 164; cf. Santa Clara Pueblo v.

Martinez, 436 U.S. 49, 60 (1978) (“[A] proper respect both for tribal sovereignty itself

and for the plenary authority of Congress in [civil actions against tribal officers] cautions

that we tread lightly in the absence of clear indications of legislative intent.”).        As

discussed, there is no explicit statutory direction indicating that the district courts should

or may exercise supplemental jurisdiction over claims arising under foreign patents, and



05-1238
                                             24
the Paris Convention, PCT, and Agreement on TRIPS neither contemplate nor allow the

extraterritorial jurisdiction of our courts to adjudicate patents of other sovereign nations.

We have also noted the territorially limited nature of patent rights. See Pellegrini v.

Analog Devices, Inc., 375 F.3d 1113, 1117 (Fed. Cir. 2004) (“[As] the U.S. Supreme

Court explained nearly 150 years ago in Brown v. Duchesne, 60 U.S. (19 How.) 183,

15 L. Ed. 595 (1857), . . . the U.S. patent laws ‘do not, and were not intended to,

operate beyond the limits of the United States.’”); Rotec Indus., Inc. v. Mitsubishi Corp.,

215 F.3d 1246, 1251 (Fed. Cir. 2000) (“‘[T]he right conferred by a patent under our law

is confined to the United States and its territories, and infringement of this right cannot

be predicated on acts wholly done in a foreign country.’” (quoting Dowagiac, 235 U.S. at

650)). Therefore, the principle that we should “avoid unreasonable interference with the

sovereign authority of other nations” applies analogously here. Empagran, 542 U.S. at

164.

       We would risk such interference by exercising supplemental jurisdiction over

Voda’s foreign patent infringement claims. Patents and the laws that govern them are

often described as complex.       Indeed, one of the reasons cited for why Congress

established our court was because it “felt that most judges didn’t understand the patent

system and how it worked.” Judge Pauline Newman, Origins of the Federal Circuit: The

Role of Industry, 11 Fed. Cir. B.J. 541, 542 (2002). As such, Cordis U.S. and one of the

amicus curiae assert, and Voda does not dispute, that the foreign sovereigns at issue in

this case have established specific judges, resources, and procedures to “help assure

the integrity and consistency of the application of their patent laws.”           Therefore,

exercising jurisdiction over such subject matter could disrupt their foreign procedures.



05-1238
                                             25
By analogy, Congress unified our patent jurisprudence by creating the Federal Circuit

and granting exclusive jurisdiction of appeals on patent claims.          28 U.S.C. § 1295.

Foreign courts exercising jurisdiction over claims based on U.S. patents would destroy

Congress’s intent to foster uniformity and to preclude forum shopping. Cf. Empagran,

542 U.S. at 168-69 (finding in antitrust context that “legally and economically technical

nature of [examining foreign law, compared with American law] means lengthier

proceedings, appeals, and more proceedings-to the point where procedural costs and

delays could themselves threaten interference with a foreign nation’s ability to maintain

the integrity of its own antitrust enforcement system”).

       Accordingly, comity and the principle of avoiding unreasonable interference with

the authority of other sovereigns dictate in this case that the district court decline the

exercise supplemental jurisdiction under § 1367(c).

              c.     Judicial economy

       Because of our lack of institutional competence in the foreign patent regimes at

issue in this case, more judicial resources could be consumed by the district court than

the courts of the foreign patent grants.           Indeed, adjudication of Voda’s British,

Canadian, European, French, and German patent claims may substantially predominate

his U.S. patent claims.      Cf. § 1367(c)(2) (stating that district courts may decline

exercising supplemental jurisdiction where “the claim substantially predominates over

the claim or claims over which the district court has original jurisdiction”).

       In addition, the likelihood of jury confusion in applying different patent regimes

could result in separate trials.    Cf. Gibbs, 383 U.S. at 726 (“Finally, there may be

reasons independent of jurisdictional considerations, such as the likelihood of jury



05-1238
                                              26
confusion in treating divergent legal theories of relief, that would justify separating state

and federal claims for trial, Fed.Rule Civ.Proc. 42(b).”).           Therefore, exercising

supplemental jurisdiction in this case could result in at least the same magnitude of

litigation as Voda filing patent infringement claims in each respective sovereign’s court.

       Voda and one amicus curiae point out that consolidated multinational patent

adjudication could be more efficient. While there may be merit in that argument, no

international treaty establishes full faith and credit, nor have we found any analogous

agreement that would require foreign countries to recognize or obligate the enforcement

of our judgments regarding foreign patents. In this case, Voda’s amended complaint

asks not only for damages and fees but also for “such other and further relief as this

Court deems just and proper.” Therefore, the additional time and resources required by

our courts may result in incomplete adjudication of the claims, prolonging and extending

the expenditures by all.

       The district court did not articulate any such judicial economy analysis, and

accordingly, this absence of analysis supports our finding that the district court abused

its discretion in this case.

               d.     Convenience

       Similarly, factors of convenience may provide additional reasons to decline

exercising supplemental jurisdiction in this case.       Again, the district court did not

articulate any such analysis, further supporting our finding that it abused its discretion.

       We note that the Supreme Court does not appear to have defined convenience in

the context of discretionary exercises of supplemental jurisdiction. While the parties

have structured their arguments in this case around forum non conveniens, they have



05-1238
                                             27
provided no case law justifying incorporation of that doctrine into the consideration of

convenience under § 1367(c). Cf. Piper Aircraft Co. v. Reyno, 454 U.S. 235, 248 n.13

(1981) (noting that Supreme Court first indicated that motions to dismiss on grounds of

forum non conveniens could be made in federal diversity actions in Williams v. Green

Bay & W.R. Co., 326 U.S. 549 (1946)); Capital Currency Exch., N.V. v. Nat’l

Westminster Bank PLC, 155 F.3d 603, 606 (2d Cir. 1998) (stating that Supreme Court

explicitly recognized applicability of forum non conveniens in federal question cases in

Gulf Oil Corp. v. Gilbert, 330 U.S. 501 (1947)). Where the doctrine does not duplicate

other factors already considered, however, forum non conveniens is a useful doctrine to

reference. For example, on one hand, the cost of obtaining and translating evidence,

especially experts in foreign patent law pursuant to Fed. R. Civ. P. 44.1 (governing

determination of foreign law), cuts against exercising supplemental jurisdiction. On the

other hand, deferring to the plaintiff’s choice of forum would support such an exercise.

              e.     Fairness

       Lastly, the act of state doctrine may make the exercise of supplemental

jurisdiction over foreign patent infringement claims fundamentally unfair. As “a ‘principle

of decision binding on federal and state courts alike,’” the act of state doctrine “requires

that, in the process of deciding, the acts of foreign sovereigns taken within their own

jurisdictions shall be deemed valid.” W.S. Kirkpatrick & Co., Inc. v. Envtl. Tectonics

Corp., Int’l, 493 U.S. 400, 406, 409 (1990) (citation omitted). In this case, none of the

parties or amicus curiae have persuaded us that the grant of a patent by a sovereign is

not an act of state. But see Mannington Mills, Inc. v. Congoleum Corp., 595 F.2d 1287,

1293-94 (3d Cir. 1979) (stating that Third Circuit was “unable to accept the proposition



05-1238
                                            28
that the mere issuance of patents by a foreign power constitutes [] an act of state” under

abstention analysis).   Therefore, assuming arguendo that the act of state doctrine

applies, the doctrine would prevent our courts from inquiring into the validity of a foreign

patent grant and require our courts to adjudicate patent claims regardless of validity or

enforceability. Given the number of U.S. patent cases that we resolve on validity or

enforceability as opposed to infringement grounds, exercising such jurisdiction could be

fundamentally unfair to the alleged infringer where, as one amicus curiae points out,

“the patent is in fact invalid and the defendant would be excused from liability on that

basis in a foreign forum.” Voda has not shown in this case that the validity of the foreign

patents would not be at issue. Indeed, Cordis U.S. asserts otherwise.

              f.     Section 1367(c) abuse of discretion

       In summary, several reasons in this case would compel the district court to

decline supplemental jurisdiction under § 1367(c): limitations imposed by treaties that

are the “supreme law of the land” and considerations of comity, judicial economy,

convenience, and fairness.       The district court undertook none of this analysis.

Accordingly, we hold that the district court abused its discretion in exercising

supplemental jurisdiction.

       As with the § 1367(a) factors of Mars, this is a non-exhaustive list, not a test, for

district courts to consider under § 1367(c). In addition, we emphasize that because the

exercise of supplemental jurisdiction under § 1367(c) is an area of discretion, the district

courts should examine these reasons along with others that are relevant in every case,

especially if circumstances change, such as if the United States were to enter into a

new international patent treaty or if events during litigation alter a district court’s



05-1238
                                            29
conclusions regarding comity, judicial economy, convenience, or fairness. However,

“[d]iscretion is not whim, and limiting discretion according to legal standards helps

promote the basic principle of justice that like cases should be decided alike . . . a page

of history is worth a volume of logic.” eBay, 126 S. Ct. at 1841-42 (Roberts, C.J.,

concurring) (quotation marks and citations omitted).

B.     Alternate Statutory Basis

       The parties also dispute on appeal whether diversity jurisdiction under § 1332

provides an alternate and independent basis for the district court to hear Voda’s claims

of foreign patent infringement. However, Voda has not pled diversity, and it is not clear

whether the district court would permit such a pleading to be made at this stage in the

proceedings. We therefore decline to decide whether the district court could properly

exercise jurisdiction based in diversity.

C.     Abstention

       The “district courts may be obligated not to decide” claims arising under foreign

patents “where one of the abstention doctrines articulated by [the Supreme] Court

applies.” Chicago, 522 U.S. at 174. Abstention doctrines “embody the general notion

that federal courts may decline to exercise their jurisdiction, in otherwise exceptional

circumstances, where denying a federal forum would clearly serve an important

countervailing interest, for example where abstention is warranted by considerations of

proper constitutional adjudication, regard for federal-state relations, or wise judicial

administration.” Id. (quotation marks and citation omitted). Because we resolve the

district court’s jurisdiction on statutory grounds, we do not discuss or make any holdings

regarding abstention here.

       We vacate the order of the district court granting Voda leave to amend his

complaint to add infringement claims based on foreign patents pursuant to the

supplemental jurisdiction statute 28 U.S.C. § 1367 and remand for further proceedings

consistent with this opinion.

NEWMAN, Circuit Judge, dissenting.




       I respectfully dissent, for the question here presented is not related to federalism and

the federal/state relationship, or to pendent jurisdiction of state law issues; nor are disputes

about foreign patents so unique as to call up the other theories collected by the panel

majority to support this ousting of United States parties from access to United States

courts. The certified question is concerned solely with the authority of a United States

court, having personal jurisdiction of the parties, to exercise its discretion to accept the
amended complaint concerning the foreign patents corresponding to the United States

patent in suit.1

       A foreign country is not a "state" in the constitutional context, and the judicial

application of foreign law plays no role in the jurisdictional balance represented by

federalism. The rules governing federal jurisdiction of supplemental state claims are

irrelevant to whether a United States court has the authority and can exercise its discretion

to decide questions that require the application of foreign law. Courts in the United States

have always had the authority to decide questions that require application of foreign law.

Federal Rule of Civil Procedure 44.1 ("Determination of Foreign Law") provides procedural

guidance. In Printz v. United States, 521 U.S. 898 (1997) the Court, comparing the judicial

and other branches of government, remarked that courts "applied the law of other

sovereigns all the time." Id. at 907. Yet the panel majority holds that a United States court


        1       Contrary to the statements of the panel majority, my position is not that the
district court has or needs personal jurisdiction of Cordis' foreign subsidiaries; my premise
is that the district court has authority and power to provide Voda with the requested relief
through Cordis US, the manufacturer and provider of the accused catheters for all five
countries. Further, both the Bonzel and Mars cases, flagged by the majority, were
discretionary decisions. In Bonzel the contract was made in a foreign country between
foreign nationals under foreign law, and was declined on the discretionary ground of forum
non conveniens. In Mars the count against a Japanese company was declined on the
discretionary ground that the kinds of patents and the structure of the devices differed
significantly between the United States and Japan.




05-1238                                      2
cannot do so, in its sound discretion, when the issue concerns patents. Thus this court

rules that the district court is precluded from considering the issues concerning the four

foreign counterparts of the United States patent that is in suit between these parties.

       The district court had agreed to receive the amended complaint. Our role, at this

pleading stage, is to determine whether that action is supportable. My colleagues hold that

the district court abused its discretion in exercising supplemental jurisdiction of the foreign

patent issues, indeed holding that the district court has no discretion to accept this

amended complaint because it involves foreign patents. I cannot agree. It is inappropriate

for the Federal Circuit to create this unique exception to the authority of American courts to

resolve controversies that require the application of foreign law.

       Access of a nation's citizenry to dispute resolution in the nation's courts is

fundamental to a nation ruled by law. This court's new rule carves an inapt exception into

judicial authority, judicial obligation, and judicial discretion. Such special treatment of

patent issues is flawed as a matter of precedent, procedure, and policy.


Courts Routinely Apply Foreign Law

       Precedent illustrates myriad situations in which the courts have determined and

applied foreign law, and also illustrates those few situations in which a court has declined to

resolve a specific foreign-based issue. Today's extreme barrier to exercise of the district

court's discretion when foreign patents are involved stands alone among the vast variety of

causes in which such determinations have been made.

       United States courts have determined and applied foreign commercial law, foreign

property law, foreign inheritance law, foreign citizenship law, foreign copyright law, foreign

trademark law, foreign liability and negligence law, and other foreign law as appropriate to
05-1238
                                              3
resolution of the dispute between the parties before the court. The principle is that a court

should apply the same law that would be applied in the nation where the event occurred, or

the law having the most significant relationship to the event in dispute. For example, in

Smith v. Condry, 42 U.S. (1 How.) 28 (1843), concerning liability for a collision between

American vessels in the port of Liverpool, the Court held that the British statutes should be

applied to determine fault, and that liability and damages should be decided under British

law. In Nashua Savings Bank v. Anglo-American Land, Mortgage & Agency Co., 189 U.S.

221, 230 (1903) the Court discussed various methods of proving foreign law, then viewed

as a question of fact, in an action by an English corporation to recover an assessment on

its capital stock; the Court explained that: "By subscribing to stock in a foreign corporation,

defendant subjects itself to the laws of such foreign country in respect to the powers and

obligations of such corporation." In Uebersee Finanz-Korporation, A.G. v. McGrath, 343

U.S. 205 (1952) the Court held that it was appropriate to determine property ownership of a

usufructuary under German law, predicate to application of the Trading with the Enemy Act.

       A sampling of recent cases yields further illustration of judicial authority and dispute-

resolution obligation when foreign law is involved: In Cambridge Literary Properties, Ltd. v.

W. Goebel Porzellanfabrik G.m.b.H. & Co., 295 F.3d 59 (1st Cir. 2002) the court observed

that the district court may apply United States copyright law, German contract law, and

Austrian inheritance law, to resolve all of the issues in the case. In Abogados v. AT&T,

Inc., 223 F.3d 932 (9th Cir. 2000) the court applied California choice of law analysis to hold

that the law of Jalisco, Mexico should be applied by the district court to an issue of tortious

interference with a contract made in Mexico between the Mexican plaintiffs and the

Mexican subsidiary of AT&T. In Tschira v. Willingham, 135 F.3d 1077 (6th Cir. 1998) the

05-1238
                                               4
court applied German law to decide whether a letter created a fiduciary duty, and then

applied Tennessee law to a fraudulent misrepresentation concerning property in

Tennessee. In Curley v. AMR Corp., 153 F.3d 5, 12 (2nd Cir. 1998) the court compared

the laws of Mexico and New York as to various torts including false imprisonment and

negligence, and stated its "agreement with the concept that appellate courts, as well as trial

courts, may find and apply foreign law"; the court held that foreign law should be applied to

the acts that occurred in Mexico unless "violative of fundamental notions of justice and

prevailing concepts of good morals." See generally 9 Charles Alan Wright and Arthur R.

Miller, Federal Practice and Procedure §§2444-446 at 644-58 (2d ed. 1995) (discussing

application of foreign law in federal courts).

       In Dorman v. Emerson Electric Co., 23 F.3d 1354 (8th Cir. 1994) the court applied

the "most significant relationship" test to determine that Canadian law applied to a personal

injury claim against a product that was designed in Missouri, manufactured in Taiwan, and

sold and used in Canada. In Indasu Int'l, C.A., v. Citibank, N.A., 861 F.2d 375, 379 (2nd

Cir. 1988) the court determined the applicable Ecuadorian law of contracts and guaranty,

then applied that law to the obligation between the United States guarantor and a

Panamanian corporation as to a contract to be performed in Ecuadorian waters. In

Mathews v. ABC Television, Inc., 776 F. Supp. 821 (S.D.N.Y. 1991) a Kenyan film-maker

sued ABC Television in New York for injuries by a rhinoceros in Kenya, alleging that an

ABC employee's reckless conduct caused the attack; the district court applied the Kenyan

comparative negligence law and case law of the East African Court of Appeals. In In re

Houbigant, Inc., 914 F. Supp. 964 (S.D.N.Y. 1995) the district court applied various

provisions of the Canadian Trade-Marks Act, and also applied the laws of the Province of

05-1238
                                                 5
Quebec and the State of New York to the interpretation of a licensing arrangement. In

Armstrong v. Virgin Records, Ltd., 91 F. Supp.2d 628 (S.D.N.Y. 2000) the district court

exercised jurisdiction of the United States and foreign copyright claims, stating that "there is

no principled reason to bar, in absolute fashion, copyright claims brought under foreign law

for lack of subject matter jurisdiction," and that "subject matter jurisdiction over any claims

properly arising under United States copyright law, potentially allowing the Court to exercise

pendent jurisdiction over claims arising under foreign law." Id. at 637.

       As for cases involving foreign patents, in Ortman v. Stanray, 371 F.2d 154 (7th Cir.

1967) the court approved the exercise of supplemental jurisdiction of counts concerning the

corresponding Canadian, Brazilian, and Mexican patents. In Mars, Inc. v. Kabushiki-Kaisha

Nippon Conlux, 24 F.3d 1369 (Fed. Cir. 1994), this court declined to decide the Japanese

patent issues, explaining that the accused devices, the scope and class of the claims, and

the charges of infringement were different in Japan and the United States. In Medigene AG

v. Loyola Univ. of Chicago, No. 98 C 2026, 2001 WL 1636916 (N.D. Ill. Dec. 19, 2001) the

district court declined to dismiss the issue of inventorship of foreign patent applications,

stating that "[Mars] makes clear that in appropriate circumstances Section 1367 permits

exercise of supplemental jurisdiction over a claim for infringement of a foreign patent." Id.

at *1. In Forbo-Giubiasco S.A. v. Congoleum Corp., 516 F. Supp. 1210 (S.D.N.Y. 1981),

the court observed that "[a] finding against Congoleum on this point [inequitable conduct in

obtaining the foreign patents] would affect only the rights between Congoleum and

Giubiasco, not Congoleum's foreign patent rights generally." Id. at 1218. In Distillers Co. v.

Standard Oil Co., 150 USPQ 42 (N.D. Ohio 1964), in a dispute involving various patents on

the manufacture of acrylonitrile, the court stated that "It cannot be doubted, nor does the

05-1238
                                               6
plaintiff question, that this Court is empowered to consider claims arising under foreign

patents." Id. (citing Aluminum Co. of Am. v. Sperry Products, Inc., 285 F.2d 911 (6th Cir.

1950) and Nat'l Latex Products Co. v. Sun Rubber Co., 274 F.2d 224 (6th Cir. 1960)).

       In no case did the court hold that it had no power or authority to receive the foreign

issue, reciting various reasons in a few situations where the court declined the foreign

issue. An example is Bonzel v. Pfizer, Inc., 439 F.3d 1358 (Fed. Cir. 2006), where this

court sustained the district court's discretion in dismissing, on the ground of forum non

conveniens, an action that required application of German contract law to interpret a patent

license agreement that was made in Germany between a German national and the Swiss

subsidiary of a United States company. Other cases are: Vanity Fair Mills, Inc. v. T. Eaton

Co., 234 F.2d 633, 645 (2nd Cir. 1956) ("the district court did not abuse its discretion in

declining to exercise its jurisdiction over that portion of the case arising in Canada and

governed by Canadian trade-mark law"); Torah Soft Ltd. v. Drosnin, 136 F. Supp.2d 276

(S.D.N.Y. 2001) (district court declined to exercise jurisdiction over foreign copyright claims

because the United States copyright claim had been dismissed); Berkshire Furniture Co. v.

Glattstein, 921 F. Supp. 1559, 1562 (W.D. Ky. 1995) (district court stated that on principles

of international comity it was "disinclined to decide issues related to the designs that arise

under U.K. and Malaysian law"); Packard Instrument Co. v. Beckman Instruments, Inc., 346

F. Supp. 408 (N.D. Ill. 1972) (district court declined to resolve patent infringement in nine

foreign countries, stating that the patentee could obtain effective relief by enforcement of its

United States patent). In none of these cases was there any assertion of judicial incapacity

to resolve the foreign issues, or of any prohibition on the exercise of discretion to accept

the case.

05-1238
                                               7
       The district court herein, in exercising its discretion to accept the Voda amended

complaint, explained that the factual situation in Ortman, supra, was more akin to this case

than the factual situation in Mars, supra. In Ortman the court had accepted the foreign

patent issues, stating that "all of the actions of defendant of which complaint is made are

the result of defendant doing similar acts both in and out of the United States," 371 F.2d at

158, whereas in Mars, citing the differences in the patents and the products this court held

that the Japanese issues would more appropriately be resolved by a Japanese court. In

contrast to the case-specific analyses in precedent, my colleagues now hold that it would

always be an abuse of discretion for the district court to decide foreign patent issues,

unless some sort of new treaty is produced. However, it is inappropriate to compel the

district court to decline the adjudicative authority available in all other areas of law.

       In explaining this unique inroad on discretion when foreign patents are involved, my

colleagues rely heavily on the criteria of supplemental jurisdiction as codified in 28 U.S.C.

§1367. However, judicial authority to determine and apply foreign law does not require that

the foreign issue is supplemental to a domestic issue. Further, even if the criteria of §1367

are applied they support, rather than negate, the district court's decision herein.

       Judicial authority to decide questions of foreign law is not a matter of the

federal/state relationship codified at 28 U.S.C. §1367. Nonetheless, the elaboration in

United Mine Workers of America v. Gibbs, 383 U.S. 715 (1966) concerning federal

supplemental jurisdiction of state law causes that have "a common nucleus of operative

fact" is a useful analogy to the Voda/Cordis situation, for the "considerations of judicial

economy, convenience and fairness to litigants" that are served by supplemental

jurisdiction, 383 U.S. at 726, are relevant to considerations of the exercise of judicial

05-1238
                                               8
discretion. If these criteria are applied they reinforce, rather than negate, the district court's

exercise of discretion to accept Voda's amended complaint.

       The principles of supplemental jurisdiction as applied to federal/state issues, 28

U.S.C. §1367, weigh on the side of the exercise of jurisdiction absent compelling reason:

       §1367(a). Except as provided in subsections (b) and (c) or as expressly
       provided otherwise by Federal statute, in any civil action of which the district
       courts have original jurisdiction, the district courts shall have supplemental
       jurisdiction over all other claims that are so related to claims within such
       original jurisdiction that they form part of the same case or controversy under
       Article III of the United States Constitution . . . .

A district court may decline to exercise supplemental jurisdiction over such a related claim:

       §1367(c). The district courts may decline to exercise supplemental
       jurisdiction over a claim under subsection (a) if --
       (1) the claim raises a novel or complex issue of State law,
       (2) the claim substantially predominates over the claim or claims over which
       the district court has original jurisdiction,
       (3) the district court has dismissed all claims over which it has original
       jurisdiction, or
       (4) in exceptional circumstances, there are other compelling reasons for
       declining jurisdiction.

(All emphases added). Although my colleagues fault the district court for "not making a

Section 1367(c) analysis," this is an inapt criticism, for the district court did not decline

jurisdiction by invoking §1367(c); instead, the court applied the principle of §1367(a) and

accepted the claim, exercising its authority and recognizing its dispute-resolution obligation.

Indeed, in Exxon Mobil Corp. v. Allapattah Services, Inc., 125 S. Ct. 2611, 2620 (2005) the

Court counseled against unduly narrowing the application of §1367(a). The Federal Circuit

in Mars applied the principles of §1367(c) and held that the Japanese patent issues should

be litigated in Japan because the "common nucleus of operative fact" required by Gibbs

was not present, but this court also stated that §1367(c) "reaffirms that the exercise of

supplemental jurisdiction is within the discretion of the district court." 24 F.3d at 1374.

                                              9
       The court's ruling today essentially eliminates this discretionary option in foreign

patent cases; the court makes no mention of the common nucleus of operative facts among

Voda's United States and foreign patent issues, and does not review the district court's

ruling on the ground of abuse of discretion. In eBay Inc. v. MercExchange L.L.C., 126 S.

Ct. 1837 (2006) the Court discouraged the carving out of an exception uniquely for patent

cases, and required that the equitable discretion of the district court be as available in

patent cases as in other cases. The panel majority strays from precedent, policy, and

prudence, in ruling that the discretionary authority of the district court cannot or should not

be exercised to resolve foreign patent disputes between parties properly before the court.

My colleagues' reliance on the rules of supplemental jurisdiction does not support their

restraint on this exercise of discretion.

       I respond to the several other justifications offered in the majority opinion, for they

also are flawed:


The Facts as Pled Support the District Court's Action

       The district court followed the Seventh Circuit's decision in Ortman, the closest

precedent. The commonality of issues in the five countries of the Voda patents, including

the United States, was before the district court. The accused catheter is the same in all five

countries; it is manufactured by Cordis Corporation in a single plant, initially at Miami

Lakes, Florida and now in Mexico. Cordis manages the Mexican plant and arranges for

shipment to the Cordis companies in the five countries where infringement is charged, viz.,

Cordis Corporation (US), Cordis S.A. (France), Cordis G.m.b.H (Germany), Cordis UK

Limited, and Cordis in Canada. All of the Cordis companies are related to the Johnson &

Johnson Company.
05-1238
                                              10
       The patents in the five countries show that they are of common origin. A PCT

(Patent Cooperation Treaty) application, based on the United States application, was filed

in the Canadian and European Patent Offices. All of the patents have identical drawings,

and the specifications are the same with additional text in the United States. The European

patent application was filed and prosecuted in English, and the French and German patents

are translations of the European patent. The British, French, and German patents have the

specification and claims of the European patent grant.2

       Cordis says in its brief that there are differences among the patents, although no

details were provided and differences are not apparent. But accepting this statement, I

doubt that any differences are beyond the understanding of a United States court, with

appropriate explanation if needed. Cordis also says that it intends to challenge the validity

of all of the patents based on a reference that was not cited in any examination; it is not

explained why a new reference cannot be considered as to not only the United States

patent, but the foreign patents.

       My colleagues, supporting their ruling that the district court should not and can not in

its discretion accept cases that raise issues of foreign patent validity and infringement, state

that "more judicial resources could be consumed by the district court than the courts of the

foreign patent grants." Maj. Op. at 26. This reason is unsupported by the pleaded facts.


       2     As for the majority's challenge to our knowledge of the content of the foreign-
language patents, the record contains all five patents, and states, without challenge, that
the German and French patents are translations of the European patent (the French patent
is headed "Traduction de Brevet Europeen").




05-1238
                                              11
Nor should a court ignore the consumption of private as well as judicial resources in

duplicative litigation between the same parties in five countries, in three languages, with

five sets of lawyers and the other trappings and burdens of trial.

       My colleagues unfairly criticize the district court for not making any findings

regarding the differences between the domestic and foreign patents, and equally unfairly

criticize the absence of expert analysis of the foreign patent laws. It is surely inappropriate

to criticize the judge for not making findings or taking evidence at the pleading stage. On a

motion to amend the pleadings the court shall accept the well-pled allegations, Fed. R. Civ.

P. 12(b)(6), and indeed no challenge to the premises has been presented.

       Discretionary authority is of broad scope, as is the judicial obligation to resolve

disputes between litigants who are properly before the court. The district court's action

reflects the "balance of conveniences," Piper Aircraft Co. v. Reyno, 454 U.S. 235, 255 n.23

(1981), for the court could have considered the convenience to Dr. Voda, a citizen of

Oklahoma, and balanced it against the convenience of multiple litigation in foreign

countries. Cordis does not argue that it would be more "convenient" for it to litigate in five

countries instead of one.

       Although a district court may decline to exercise its jurisdiction when it appears that

the convenience of the parties and the court and the interests of justice are such that the

action should be tried in another forum, id. at 249-50, this determination is committed to the

sound discretion of the district court. See, e.g., Leetsch v. Freedman, 260 F.3d 1100,

1102-03 (9th Cir. 2001) ("When we review a forum non conveniens determination, we give

less deference to a foreign plaintiff's choice of a United States forum than to a domestic

plaintiff's choice" and "[w]hether to dismiss an action on forum non conveniens grounds

05-1238
                                              12
require the district court to consider the availability of an adequate alternative forum, and

then to consider whether several 'private' and 'public' interest factors favors dismissal.").

Cordis has the burden of persuasion that the district court abused its discretion in choosing

to receive the amended complaint. Our appellate role is to determine whether Cordis has

met this burden and has shown that the district court's exercise of discretion is not

sustainable in this case; it is an improper appellate ruling to remove that discretion.


Complexity of Law or Fact

       I turn to the matter of complexity, for this aspect is also pressed in the panel

majority's reasoning. My colleagues propose that in view of the complexities that may arise

in connection with foreign patents, United States courts should not or can not exercise their

discretion to enter the arena. Such a sweeping elimination of judicial authority contravenes

the fundamentals of judicial responsibility, for judges cannot avoid cases because they may

be complex. The complexity of patent law does not evict the district court from its

discretionary authority.

       My colleagues appear to believe that each nation's patent on Dr. Voda's invention

covers a different scope of subject matter. The proposition that the scope of counterpart

patents, particularly those having identical claims, will usually vary significantly will come as

a surprise and shock to the holders of literally millions of counterpart patents. In this case

all five patents are of common origin and text, and the patents in Great Britain, France, and

Germany are identical as granted by the European Patent Office. It is well recognized that

most inventions receive consistent protection under the patent laws of the major industrial




05-1238
                                               13
nations.      The few areas of difference are well understood by practitioners.3            The

international structure of patent laws, patent practitioners, and patent treaties, is bottomed

on this commercial premise. International business depends on this expectation and

reality.

           There is no assertion that the Voda catheter is so complicated as to test the nuances

of comprehension and law. The panel majority states that its concern about "construing"

different claims or even the same claims in different countries, and that expert testimony

might be required. Expert testimony is not unusual in patent litigation, and experts on the

meaning and scope of the claims in these countries are undoubtedly available if needed.

See Fed. R. Civ. P. 44.1.4

           "The parties, therefore, carry the burden of proving foreign law; where they do not do

so, we 'will ordinarily apply the forum's law.'" Ferrostaal, Inc. v. M/V Sea Phoenix, 447 F.3d



       3     Voda's catheter is a mechanical device, and does not raise new policy issues
based on evolving areas of technology, such as the role of patents on computer software or
genetic products.

       4      Rule 44.1. Determination of Foreign Law. A party who intends to raise an
issue concerning the law of a foreign country shall give notice by pleadings or other
reasonable written notice. The court, in determining foreign law, may consider any relevant
material or source, including testimony, whether or not submitted by a party or admissible
under the Federal Rules of Evidence. The court's determination shall be treated as a ruling
on a question of law.




05-1238

212, 216 (3rd Cir. 2006) (quoting Bel-Ray v. Chemrite Ltd., 181 F.3d 435, 440 (3d

Cir.1999)); Banco de Credito Industrial, S.A. v. Tesoreria Gen., 990 F.2d 827, 836 (5th Cir.

1993) (analyzing Spanish and French law and holding that "[w]hen the parties have failed

to conclusively establish foreign law, a court is entitled to look to its own forum's law in

order to fill in any gaps.").

       We do not know whether the accused Cordis device is a simple copy of the Voda

invention or whether it embodies significant changes; that is, we do not know whether claim

"construction," under any law, will be necessary. As for foreign languages, about which my

colleagues also express concern, the Canadian and British patents are in English, as is the

European patent of which the German and French patents are translations.                   The

prosecution history in the European Patent Office is in English, as of course in Canada and

the United States. It surely is not apparent that multiple litigation of the same issues in five

countries and three languages is likely to be more economical of judicial time and litigation

expense, and more likely to achieve a correct and just result, than resolving all of the issues

before one judge in one case and one language. This aspect cannot serve to negate the

district court's exercise of discretion to receive these issues.

       My colleagues also express concern about "jury confusion" when proving

infringement of patents written in other languages and under foreign law. I take note that

the Uniform Interstate and International Procedure Act, Article IV §4.03, states that "the

court, not the jury, shall determine foreign law." See also Fed. R. Civ. P. 44.1. It need not

be ignored that the extent to which the question of infringement is presented to a jury is

diminished in the United States since the advent of the Markman practice; and whether a



05-1238
                                              15
corresponding foreign question under the laws of a country that does not have a jury

system would avoid any Seventh Amendment obligation is not here at issue.

       The panel majority also states its concern that issues of foreign patents may not be

correctly decided by a United States court. Undoubtedly this concern fits all of the areas in

which courts have applied foreign law, and could be a factor in a district court's

determination of whether to exercise jurisdiction in a particular case. However, such a

discretionary determination is quite different from the panel majority's ruling that discretion

should not be exercised to accept and decide foreign patent issues.

       My colleagues propose that permitting exercise of the district court's discretion to

accept jurisdiction "could be fundamentally unfair to the alleged infringer." Indeed, fairness

is an important aspect of discretionary rulings, and fairness to both sides must be

considered. The panel majority does not explain its apparent balance of fairness in its

holding that the alleged infringer is always more disadvantaged and can only be sued in the

situs of the infringement. Such considerations would have evicted American courts in many

areas of law, as in the representative cases cited earlier in this opinion. This concern does

not warrant treating patent cases differently from all other causes of action.

       In this case, the district court was willing to take on the foreign issues. Perhaps the

district court gave weight to the fact that the United States patent was being litigated

anyway, on the same grounds and against the same device that is at issue in all five

countries. Perhaps the court gave weight to equitable considerations, for they are always

relevant to judicial discretion. None of the aspects here raised supports departing from the

authority of courts to resolve disputes between parties that are properly before them,

whether or not foreign law is involved. The fundamental question now presented is whether

05-1238
                                              16
a district court will be permitted to retain its judicial authority, or will this specific area be

uniquely limited, whatever the position of the district court as to its discretion and its

obligation.


The Local Action Doctrine

       My colleagues also refer to the "local action" doctrine as barring the district court's

jurisdiction of foreign patent issues. This "doctrine" arose in United States jurisprudence in

the early days of the Republic, clarifying the jurisdiction of the state courts with respect to

each other.    In Livingston v. Jefferson, 15 F. Cas. 660 (C.C.D. Va. 1811), the court

recognized the common law concept of local action and established that an action involving

real property can be brought only within the state of the United States where the land is

located. Such rulings have no relation to whether a United States court can resolve a dispute

between persons personally before the tribunal by applying the law of a foreign country,

whatever the issue. See generally 14D Charles Alan Wright, Arthur R. Miller & Edward H.

Cooper, Federal Practice and Procedure: Jurisdiction and Related Matters 2d §3822, at 451-

54 (2007). It is obscure how this "doctrine" supports my colleagues' ruling that a United

States court cannot resolve disputes that raise questions of foreign patent law.


The Act of State Doctrine

       The panel majority also invokes the "Act of State" doctrine as justification for barring

the district court from choosing to decide the issues of Voda's foreign patents. The theory

appears to be that the grant of a foreign patent is a governmental act of state, and thereby

untouchable by a United States court. Thus the panel majority proposes that the district

court's discretionary act would "prejudice the rights of other governments" to decide the

05-1238
                                               17
validity and enforceability of their patents. That proposition is unsupported. In Mannington

Mills, Inc. v. Congoleum Corp., 595 F.2d 1287, 1293-94 (3rd Cir. 1979) the court rejected the

theory that "the mere issuance of patents by a foreign power constitutes either an act of

state, as that term has developed under case law, or an example of governments'

compulsion." In Forbo-Giubiasco, 516 F. Supp. at 1217 the court explained that "it cannot be

said that a determination by an American court that a private company failed to present

relevant information to a foreign patent office could interfere with our government's conduct

of foreign affairs."

       In Banco National de Cuba v. Sabbatino, 376 U.S. 398 (1963) the Court explained that

"[t]he act of state doctrine in its traditional formulation precludes the courts of this country

from inquiring into the validity of the public acts a recognized foreign sovereign power

committed within its own territory," and that the doctrine precludes judicial determination of

the legality of acts of foreign states within their own territories which might embarrass the

executive department in its conduct of foreign affairs. Id. at 427-49. Not every governmental

action is an act of state, and not every ministerial activity carries the political and international

implications of that usage.

       Whether a particular governmental action is properly viewed as an act of state has

been explained in a variety of contexts; the common thread is whether the issue is one that is

normally consigned to the executive branches, such that an international dispute is resolved

by political negotiations between diplomats; or whether the issue is more suitable to the

individual review that is given to litigants in judicial proceedings dealing with specific facts.

See generally 12 A.L.R. Fed. 707 (2006) ("Modern Status of the Act of State Doctrine"). The

fundamental criterion is whether the governmental action is a significant public act or whether

05-1238
                                                18
it is a ministerial function, accompanied by whether the proposed judicial review is directed to

the public interests of the nation as served by the governmental act, or is a private effort to

enforce a private claim.

       Clearly, the grant of a patent is not an Act of State, whether done by the United States

or by a foreign country. No support has been offered for so creative an application of

international law; this "doctrine" provides no support for this court's removal of judicial

discretion of United States courts to resolve a commercial dispute between private parties

involving private patent rights. The Act of State doctrine is not relevant to judicial review of

the Voda foreign patents; patent validity and infringement are legal and commercial issues,

not acts of state. This doctrine does not create an exception that excludes foreign patents

from access to dispute resolution in our courts.


Enforcement Is Not An Issue

       There is no issue raised by either party concerning enforcement by a foreign court of

the district court's potential decision concerning any of the Voda foreign patents. This case

does not raise issues of comity, treaty, and diplomacy, when judgments are sought to be

enforced in another country. The complexities of enforcement of foreign judgments, at which

my colleagues hint, indeed serve to protect litigants from abusive procedures, and under the

various protocols and treaties that relate to foreign judgments, a foreign court can refuse to

accept a decision of another nation's tribunal. See Laker Airways Ltd. v. Sabena, Belgian

World Airlines, 731 F.2d 909, 937-38 (D.C. Cir. 1984) ("No nation is under an unremitting

obligation to enforce foreign interests which are fundamentally prejudicial to those of the

domestic forum."); Motorola Credit Corp. v. Uzan, 388 F.3d 39, 60 (2d Cir. 2004) ("orders of

foreign courts are not entitled to comity if the litigants who procure them have 'deliberately
05-1238
                                               19
courted legal impediments' to the enforcement of a federal court's orders") (citation omitted);

Finanz AG Zurich v. Banco Economico S.A., 192 F.3d 240, 246 (2d Cir. 1999) (judicial

proceedings may receive comity to the extent that the "foreign court had proper jurisdiction

and enforcement does not prejudice rights of United States citizens or violate domestic public

policy"). See generally Restatement (Third) of Foreign Relations Law of the United States

§§481-82 (1987) (recognition and enforcement of foreign judgments and grounds for non-

recognition of such judgments).

       The enforcement aspect was not raised by either party. The district court may have

recognized that both Dr. Voda and Cordis Corporation, the manufacturer for all five countries,

are within the district court's personal jurisdiction. In Forbo-Giubiasco, supra, the court

explained that its findings with respect to the foreign patents were directed to the obligations

of the parties to each other, and not to whether or how a foreign tribunal would view the

decision.

       The issues and relationships herein reinforce the district court's exercise of discretion

to accept the amended complaint, and further impugns this court's withdrawal of the district

court's discretion as to foreign patents. There is no sound reason why speculative concerns

of enforcement in foreign countries warrant depriving the district court of its discretion to

resolve this dispute between these United States parties. While we do not know the extent to

which the district court might find liability and impose constraints in this case, the answer to

this dispute is not to bar the court from hearing it.


The Role of Patent Treaties

       The panel majority proposes that it would violate the Paris Convention for the

Protection of Industrial Property, the Patent Cooperation Treaty, and the TRIPS Agreement
05-1238
                                             20
of the World Trade Organization, if the United States were to consider the validity and

infringement of Dr. Voda's foreign patents. None of these treaties prohibits resolution by a

national court of private disputes that include foreign patent rights. The question is not as

presented by the panel majority, whether any treaty imposes "an international duty" on a

nation's courts to render decision concerning foreign patents. The question is whether any

treaty prohibits a national court from resolving a dispute between entities under the personal

jurisdiction of the court. No treaty bars such dispute resolution.


Dispute Resolution is an Obligation of Courts

       The ruling of the panel majority departs not only from judicial precedent, but from

judicial obligation. Although the court appears to concede that the district court may have

"jurisdiction" to resolve the foreign aspects of this dispute, my colleagues hold that this

authority cannot be exercised to resolve this dispute. This holding contravenes the judicial

role. The district court has both the power and the obligation to resolve the dispute between

the parties. See Cheney v. U.S. District Court for the District of Columbia, 542 U.S. 367, 370

(2004) (referring to the district court's constitutional responsibility to resolve cases and

controversies within its jurisdiction); Kirkpatrick & Co. v. Envt'l Tectronics Corp. Int'l, 493 U.S.

400, 409 (1990) ("Courts in the United States have the power, and ordinarily the obligation, to

decide cases and controversies properly presented to them.").

       The majority postulates that discretion perhaps could be exercised "especially if

circumstances change, such as if the United States were to enter into a new international

patent treaty or if events during litigation alter a district court's conclusion regarding comity,

judicial economy, convenience, or fairness." This is at best a confusing wrap-up to this

important question, for no new international treaty is at hand, and the proposal that events
05-1238
                                           21
during litigation may change the conclusion is not helpful, for the question is whether this

litigation will be conducted at all.

       The question here is simply whether, in a dispute between United States entities of

whom the district court has personal jurisdiction, does the court have discretion to resolve

aspects that concern foreign patents. The panel majority's conclusion that the court cannot

exercise its discretion to do so is contrary to principle, practice, and judicial obligation.


Comity, Harmonization, and the Future

       Comity is a complex concept of international law, and its generalization to evict United

States courts from their dispute-resolution obligation is not supported on any theory of

comity. See Hilton v. Guyot, 159 U.S. 113, 164 (1895) (defining comity as "neither of

absolute obligation . . . nor of mere courtesy and good will" but "the recognition which one

nation allows within its territory to the legislative, executive or judicial acts of another nation,

having due regard both the international duty and convenience, and to the rights of its own

citizens . . . who are under the protection of its laws."). Comity has no relevance to the need

to apply foreign law and the obligation and authority to meet that need. In Piper Aircraft, 454

U.S. at 260 n.29, the Court observed that "[t]he need to apply foreign law . . . alone is not

sufficient to warrant dismissal when a balancing of all relevant factors shows that the

plaintiff's chosen forum is appropriate."

       The panel majority raises the specter that foreign courts might adjudicate United

States patent rights, proposing that if our courts are permitted to decide questions under

foreign patent law, other countries will feel free to decide questions of United States patent

law. Cordis too sounds the alarm, stating that creative litigants will choose exotic foreign

forums to resolve complex patent issues, and that the district court's decision will open the
05-1238
                                          22
door to international chaos. I doubt that a United States district court is an exotic foreign

forum; and it is not new for courts in other countries to apply the law of other nations when

warranted. Courts in other countries have not refrained from applying foreign patent law,

including United States law. A Japanese court recently applied the United States doctrine of

equivalents in a suit between Japanese companies that included questions of infringement of

United States patents, in K.K. Coral Corp. v. Marine Bio K.K., Case No. 1943(wa)/2002

(Tokyo District Court, Oct. 16, 2003). All nations have recognized their obligation to provide

a judicial forum to address disputes involving their citizens; no warrant has been shown to

remove foreign patents from this purview.

       Proponents of patent "harmonization" point to the similarity of the policies that underlie

patent law of all industrialized nations, and stress that for most technologies the same scope

of practical protection is available to industrial development in all nations. It would be

anomalous indeed for the United States now to rule that the courts cannot understand patent

principles as applied in other nations.

       Preclusion and prejudgment are inappropriate and unnecessary. From my colleagues'

extreme limitation and bar on the district court's exercise of discretion to receive and resolve

foreign patent issues, I respectfully dissent.
