ORDER GRANTING IN PART AND DENYING IN PART PLAINTIFFS' MOTION FOR SUMMARY JUDGMENT
JAMES I. COHN, District Judge.
THIS CAUSE is before the Court on Plaintiffs' Motion for Summary Judgment [DE 52]. The Court has considered the Motion and the exhibits thereto, Defendants' Response [DE 61], Plaintiffs' Reply [DE 76] and the exhibits thereto, the record in this case, the argument of counsel on June 4, 2009, and is otherwise advised in the premises.
The Court holds that summary judgment will be granted on behalf of Plaintiff with respect to the issues of standing,[1] anticipation, obviousness, and laches.[2] Summary judgment will be denied on the issues of infringement and inequitable conduct.

I. BACKGROUND
This action is based on Plaintiffs' claim that Defendants have sold or installed products that infringe on U.S. Patent No. 6,895,881 ("the '881 patent"). The subject matter of the '881 patent is a synthetic teak decking product that is often used with marine vessels.
After a contentious discovery period, during which a number of motions regarding discovery failures were filed, Plaintiffs filed the instant Motion for Summary Judgment. In the Motion, Plaintiffs argue that Defendants have not identified sufficient witnesses or evidence to support their affirmative defenses. Plaintiffs further argue that the issue of infringement is capable of being determined by looking to the expert opinions alone, particularly in light of the fact that Defendants did not produce an expert with experience and training in the particular field of the invention.
Defendants' Response argues that there are disputed issues of material fact that preclude summary judgment. To support this argument, Defendants refer generally to the pleadings and attachments in the record, including Defendants' own motions for summary judgment. Defendants also argue that a court entertaining a motion for summary judgment should not make credibility determinations on conclusory opinion testimony, particularly when the opinion addresses the ultimate issue in the case.

II. LEGAL STANDARD
The Court may grant summary judgment "if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to *1300 any material fact and that the moving party is entitled to a judgment as a matter of law." Fed.R.Civ.P. 56(c). The movant "bears the initial responsibility of informing the district court of the basis for its motion, and identifying those portions of [the record] which it believes demonstrate the absence of a genuine issue of material fact." Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). To discharge this burden, the movant must point out to the Court that there is an absence of evidence to support the nonmoving party's case. Id. at 325, 106 S.Ct. 2548.
After the movant has met its burden under Rule 56(c), the burden of production shifts and the nonmoving party "must do more than simply show that there is some metaphysical doubt as to the material facts." Matsushita Electric Industrial Co. v. Zenith Radio Corp., 475 U.S. 574, 586, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986). According to the plain language of Rule 56(e), the non-moving party "may not rest upon the mere allegations or denials of the adverse party's pleadings," but instead must come forward with "specific facts showing that there is a genuine issue for trial." Fed.R.Civ.P. 56(e); Matsushita, 475 U.S. at 587, 106 S.Ct. 1348.
Essentially, so long as the non-moving party has had an ample opportunity to conduct discovery, it must come forward with affirmative evidence to support its claim. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 257, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). "A mere `scintilla' of evidence supporting the opposing party's position will not suffice; there must be a sufficient showing that the jury could reasonably find for that party." Walker v. Darby, 911 F.2d 1573, 1577 (11th Cir.1990). If the evidence advanced by the non-moving party "is merely colorable, or is not significantly probative, then summary judgment may be granted." Anderson, 477 U.S. at 249-50, 106 S.Ct. 2505.

III. ANALYSIS

1. Summary Judgment is Granted in Favor of Plaintiffs' on the Issue of Standing

The Patent Act provides that only "[a] patentee" is entitled to bring a civil action "for infringement of his patent." 35 U.S.C. § 281. The term "patentee" includes "not only the patentee to whom the patent was issued but also the successors in title to the patentee." 35 U.S.C. § 100(d). "Although `ownership' and `inventorship' are not identical for patent law purposes, they are related. Inventorship provides the starting point for determining ownership of patent rights. The true and original inventor must be named in the application for a patent and, absent some effective transfer or obligation to assign the patent rights, the original inventor owns the right to obtain the patent." University Patents, Inc. v. Kligman, 762 F.Supp. 1212, 1218-19 (E.D.Pa.1991). On the record before this Court, and for reasons which were discussed in open Court on June 4, 2009 and which will be described fully in the Court's Order Denying Defendants' Renewed Motion to Dismiss, the Court finds that Plaintiffs have established standing to bring this action.

2. Summary Judgment is Granted in Favor of Plaintiffs on Defendants' Affirmative Defenses of Invalidity Due to Anticipation and Obviousness

In patent actions, a patent is presumed to be valid and the party challenging a patent's validity has the burden of proving the invalidity by clear and convincing evidence. See 35 U.S.C. § 282; Central Admixture Pharmacy Services, Inc. v. Advanced Cardiac Solutions, P.C., 482 F.3d 1347, 1357-58 (Fed.Cir.2007) (citing U.S. *1301 Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1564 (Fed.Cir.1997)). "Our precedent holds that the presumption of validity afforded a U.S. patent by 35 U.S.C. § 282 requires that the party challenging validity prove the facts establishing invalidity by clear and convincing evidence." Verdegaal Bros. Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed.Cir.1987) (citations omitted). Plaintiffs argue that "Defendants evidence provides a list of prior art materials without explanation of how they obviate or anticipate Plaintiffs' patent." (Reply at 9.) After considering the limited record before this Court, in particular the lack of evidence and argument set forth by Defendants on their affirmative defenses that the '881 patent is invalid due to anticipation by prior art and obviousness, the Court finds that Defendants have not met their burden to survive summary judgment on these issues.
"A prior art reference anticipates a patent claim if the reference discloses, either expressly or inherently, all of the limitations of the claim." Finnigan Corp. v. International Trade Com'n, 180 F.3d 1354, 1365 (Fed.Cir.1999); accord Continental Can Co. v. Monsanto Co., 948 F.2d 1264, 1268 (Fed.Cir.1991) ("Anticipation... requires that the identical invention that is claimed was previously known to others and thus is not new."). Here, Defendants have not even attempted to demonstrate how "an anticipatory reference" shows "all of the limitations of the claims arranged or combined in the same way as recited in the claims" of the '881 patent. Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1370 (Fed.Cir.2008). Therefore, Plaintiffs' Motion will be granted with respect to the issue of anticipation.
In order to show that a claim is invalid due to obviousness, the challenger must prove that the differences between the invention and the prior art "are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains." 35 U.S.C. § 103(a). Whether the invention was obvious under § 103 is to be determined by the following analysis:
Under § 103, the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue are to be ascertained; and the level of ordinary skill in the pertinent art resolved. Against this background the obviousness or nonobviousness of the subject matter is determined. Such secondary considerations as commercial success, long felt but unsolved needs, failure of others, etc., might be utilized to give light to the circumstances surrounding the origin of the subject matter sought to be patented.
Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 17-18, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966); see also KSR Intern. Co. v. Teleflex Inc., 550 U.S. 398, 406-07, 127 S.Ct. 1727, 167 L.Ed.2d 705 (2007). Again, Defendants simply have not described the prior art in any degree that would allow this Court to determine that this analysis renders the '881 patent invalid. At this stage in the litigation, Defendants, who bear the burden, cannot escape summary judgment on this affirmative defense without a greater showing than what is before this Court. Accordingly, summary judgment is granted on the issue of anticipation.

3. Summary Judgment is Denied on the Issue of Inequitable Conduct

To establish the existence of inequitable conduct in a patent case, a party must present "evidence of affirmative misrepresentation of a material fact, failure to disclose material information, or submission *1302 of false material information, coupled with an intent to deceive." Ulead Systems, Inc. v. Lex Computer & Management Corp., 351 F.3d 1139, 1144 (Fed.Cir. 2003). Thus, a claim of inequitable conduct has two elements of materiality and intentboth of which must be established by clear and convincing evidence. Bruno Indep. Living Aids, Inc. v. Acorn Mobility Servs., Ltd., 394 F.3d 1348, 1351 (Fed.Cir. 2005). If a defendant succeeds in proving materiality and intent to deceive, the Court must weigh these findings in light of all of the circumstances and determine if there was inequitable conduct. See Purdue Pharma L.P. v. Boehringer Ingelheim GmbH, 237 F.3d 1359, 1366 (Fed.Cir.2001). "This requires a careful balancing: when the misrepresentation or withheld information is highly material, a lesser quantum of proof is needed to establish the requisite intent. In contrast, the less material the information, the greater the proof must be." Purdue Pharma L.P. v. Endo Pharms., Inc., 438 F.3d 1123, 1128-29 (Fed.Cir.2006).
Patent applicants "have a duty to prosecute patent applications in the Patent Office with candor, good faith, and honesty." Honeywell Int'l Inc. v. Universal Avionics Sys. Corp., 488 F.3d 982, 999 (Fed.Cir.2007). The materiality of a prior art product turns on whether "a reasonable examiner would consider it important in deciding whether to allow the application to issue as a patent." Symantec Corp. v. Computer Assocs. Int'l, Inc., 522 F.3d 1279, 1297 (Fed.Cir.2008) (quotation omitted). "Close cases should be resolved by disclosure, not unilaterally by the applicant." La Bounty Mfg., Inc. v. U.S. Int'l Trade Comm'n, 958 F.2d 1066, 1076 (Fed. Cir.1992).
Intent does not have to be proven by direct evidence. ATD Corp. v. Lydall, Inc., 159 F.3d 534, 547 (Fed.Cir.1998). Rather, in the absence of a credible explanation, "intent to deceive is generally inferred from the facts and circumstances surrounding a knowing failure to disclose material information." Id. "To satisfy the requirement of ... intent to deceive ..., the involved conduct, viewed in light of all the evidence, including evidence of good faith, must indicate sufficient culpability to require a finding of intent to deceive." M. Eagles Tool Warehouse, Inc. v. Fisher Tooling Co., Inc., 439 F.3d 1335, 1341 (Fed.Cir.2006) (quotation omitted). A motion for summary judgment on inequitable conduct "may be granted when, drawing all reasonable factual inferences in favor of the non-movant, the evidence is such that the non-movant cannot prevail." ATD Corp., 159 F.3d at 547.
This issue presents a much more difficult question as compared to anticipation and invalidity for several reasons. First and foremost, Defendants filed a Motion for Summary Judgment on Unenforceability [DE 49] that articulates the grounds for this affirmative defense. In short, Defendants argue that Plaintiffs committed inequitable conduct before the United States Patent and Trademark Office ("PTO") during the application process for the '881 patent, thereby rendering the '881 patent unenforceable. In particular, Defendants argue that Plaintiffs (1) withheld material information from the PTO, i.e., a decision by a foreign tribunal revoking a New Zealand patent based on the same subject matter as the '881 patent ("IPONZ Decision"),[3] and (2) misrepresented *1303 their ownership interest in the '881 patent.
Second, although Plaintiffs have submitted witness declarations that purportedly establish a good faith explanation for the nondisclosure of the IPONZ Decision, the Court finds that Defendants should have the opportunity to cross examine the witnesses and the Court should have the ability to evaluate the credibility of their explanations prior to determining whether or not the element of intent has been satisfied.
Finally, Plaintiffs are correct that the Court should exercise caution in according weight to a foreign patent office, which uses different procedures, standards and laws. See Heidelberger Druckmaschinen AG v. Hantscho Comm'l Prods., Inc., 21 F.3d 1068, 1072 (Fed.Cir.1994). Indeed, this is why the Court did not simply rely on the IPONZ Decision to establish Defendants' burden on its claims that the '881 patent is invalid due to anticipation or obviousness. In addition, Plaintiffs argue that they chose not to participate in the revocation proceedings involving the New Zealand patent. However, granting Defendants all reasonable inferences at this stage, the Court finds that the materiality of the revocation proceedings themselves, even prior to the IPONZ Decision, is a question that cannot be resolved in the Plaintiffs' favor on summary judgment. "Determining at summary judgment that a patent is unenforceable for inequitable conduct is permissible, but uncommon." Digital Control Inc. v. The Charles Machine Works, 437 F.3d 1309, 1313 (Fed.Cir. 2006). Therefore, the Court will deny Plaintiffs' Motion with respect to inequitable conduct and the Court will conduct a bench trial on this issue.

4. Summary Judgment is Denied on the Issue of Infringement

To succeed on an infringement claim, a patentee must supply sufficient evidence to prove that the accused product or process meets every element or limitation of a claim. See Lemelson v. United States, 752 F.2d 1538, 1551 (Fed.Cir.1985) ("It is ... well settled that each element of a claim is material and essential, and that in order for a court to find infringement, the plaintiff must show the presence of every element ... in the accused device."); Laitram Corp. v. Rexnord, Inc., 939 F.2d 1533, 1535 (Fed.Cir.1991) ("the failure to meet a single limitation is sufficient to negate infringement of the claim").
Plaintiffs assert that the Court can determine infringement relying, in large part, on the opinion of Plaintiffs' expert. Plaintiffs argue that their position is particularly strong here because Defendants' expert report and testimony on this issue of infringement has been excluded by the Court. Defendants argue that "an expert opinion is just that, an `opinion.'" (Response at 5.) As the Federal Circuit has found, nothing in the Federal Rules of Evidence require a fact finder to accept an expert's conclusion. See Rohm and Haas Co. v. Brotech Corp., 127 F.3d 1089, 1092 (Fed.Cir.1997) ("The patentee bore the burden of proving that the accused product or process satisfied each element of the claims. [The patentee] offered nothing more than its expert's general opinion that the accused product or process infringed the patents. The district court determined that the patentee had not satisfied its burden *1304 of proof on two claim elements.") Defendants' counsel also argued that Plaintiffs were "trying to have it both ways" because in their motion to exclude Defendants' expert, Plaintiffs argued that expert testimony that "constitutes a legal conclusion or otherwise tells `the [fact-finder] what result to reach' ... in no way assists the trier of fact." (Plaintiff's Daubert Motion [DE 51] at 14) (quoting Montgomery v. Aetna Cas. & Sur. Co., 898 F.2d 1537, 1541 (11th Cir.1990)). Even putting aside this apparent inconsistency in Plaintiffs' positions, the Court finds that Plaintiffs failed to demonstrate that no reasonable jury could find in favor of Defendants on the issue of infringement. Accordingly, Plaintiffs' Motion will be denied and the Court will conduct a jury trial regarding whether Defendants' products infringe upon the '881 patent.

IV. CONCLUSION
In light of the foregoing, it is ORDERED AND ADJUDGED as follows:
1. Plaintiffs' Motion for Summary Judgment [DE 52] is GRANTED in part and DENIED in part.
2. Plaintiffs' Motion is granted with respect to the issues of standing, anticipation, obviousness, and laches.
3. Plaintiffs' Motion is denied on the issues of infringement and inequitable conduct.


CORRECTED ORDER DENYING DEFENDANTS' MOTION TO RECONSIDER, ALTER OR AMEND[1]
THIS CAUSE is before the Court on Defendants' Motion to Reconsider, Alter or Amend Order Granting in Part Plaintiffs' Motion for Summary Judgment [DE 124]. The Court has considered the Motion, Plaintiffs' Response [DE 130], the argument of counsel on June 16, 2009, the applicable law, the record in this case, and is otherwise advised in the premises.
Defendants' Motion asks this Court to reconsider, alter or amend its holdings with respect to standing and invalidity contained in the Order Granting in Part Plaintiffs' Motion for Summary Judgment [DE 112]. This Court fully articulated its reasoning with regard to the standing issue in the Order Denying Defendants' Renewed Motion to Dismiss [DE 126] and the Court holds that there is no reason reconsider, alter or amend that ruling. Accordingly, this Order will focus on the two remaining issues raised in Defendants' Motion, anticipation and obviousness.

I. BACKGROUND
This action is based on Plaintiffs' claim that Defendants have sold or installed products that infringe on U.S. Patent No. 6,895,881 ("the '881 patent"). The subject matter of the '881 patent is a synthetic teak decking product that is often used with marine vessels.

1. The Original Invention

On June 24, 1999, Derek Gordon Whitaker filed a Great Britain patent application for a "Shape Conforming Surface." (DE 30-2.) On October 8, 1999, Whitaker filed another Great Britain patent application disclosing the subject matter as "Flexible Surface Covering." (DE 30-3.) On March 7, 2000, Flexiteek International AS ("Flexiteek International") and Whitaker entered into an agreement whereby Whitaker assigned his rights to the Great Britain patent applications and the underlying *1305 invention to Flexiteek International. (See Ex. A to DE 30-5.) In exchange, Whitaker received £250,000.00, royalty fees, a 10% share of stock in Flexiteek International and a 36-month employment contract as Manager of Research and Development with Flexiteek International. (Id.)
On June 19, 2000, Flexiteek International converted the intellectual property acquired through the agreement, including the two Great Britain patent applications filed by Whitaker, into International Patent Application Number PCT/SE00/0132 ("PCT Application") for a "Shape Conforming Surface Covering." (DE 30-6.) The PCT Application claims priority to both of the Great Britain applications. (Id.)

2. The New Zealand Patent

On September 12, 2001, Flexiteek International filed a New Zealand patent application for a "shape conforming surface covering," which claimed priority in the two Great Britain patent applications. (See DE 124-9 at 2.) A notice of acceptance of the New Zealand patent application issued on September 23, 2002. (Id.) In 2003, Flexiteek International filed a lawsuit against Tek-Dek NZ Limited ("Tek-Dek") for infringement of the New Zealand patent. In response to that suit, Tek-Dek filed an application for revocation of the New Zealand patent on July 4, 2003.
The infringement action was settled in August 2004 with Tek-Dek "agreeing to a destruction of all infringing products, an injunction from selling any further infringing products in New Zealand, and payment of money damages and costs." (DE 59-4 ¶ 8.) Nevertheless, the revocation proceedings went forward. After filing a counterstatement in the revocation proceeding, Flexiteek International declined to participate any further. According to Svein Abrahamsen, President and CEO of the company, Flexiteek International "elected to abandon the New Zealand Patent for a variety of reasons. First and foremost, the amount of business from sale of Flexiteek's synthetic teak decking products in New Zealand did not warrant the expense of contesting the pending application for revocation. Secondly, since the New Zealand Patent was granted in September 23, 2002, there was a substantial change in the technology of synthetic teak decking products which made the claims in the New Zealand Patent outdated." (Id. ¶ 10.) On April 18, 2005, the Intellectual Property Office of New Zealand ("IPONZ") issued a decision revoking the New Zealand patent. (See DE 124-9.) In particular, the IPONZ found "that grounds [of prior publication, obviousness and not an invention] have been made out. I do not believe there is any basis for amendment to save any aspect of the claims as accepted. The patent is revoked." (Id. at 32.)

3. The U.S. Patent

On December 18, 2001, Flexiteek International converted the PCT Application into a U.S. patent application with Whitaker named as the applicant. (DE 30-11.) The United States Patent and Trademark Office ("PTO") did not accept the patent application until August 5, 2003, after Flexiteek took several procedural steps required as a result of Whitaker's lack of cooperation in the application process. (DE 30-20.) In a communication, dated June 1, 2004, the PTO rejected the U.S. patent application as filed. (See DE 124-2.) Specifically, the PTO found that "[c]laims 1-17 are rejected under 35 U.S.C. 112, second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention." (Id. at 4.) In addition, the PTO found *1306 that "[c]laims 1-4, 6, 7, 8, 16 and 17 are rejected under 35 U.S.C. 103(a) as being unpatentable over Zwilgmeyer in view of Anstadt." (Id. at 5.) In discussing "obviousness," the patent examiner also cited the patents of Harshberger, Hinds et al., and Hunter et al. (Id. at 8.) The patent examiner also cited the Klammt patent "to show grooved flat bottoms." (Id.)
On September 1, 2004, Plaintiffs' patent counsel replied to the PTO and submitted an application including 26 claims with "amendments and remarks" in response to the communication discussed above. (See DE 46-3 at 36-56.) In a communication, dated October 13, 2004, the PTO rejected claims 1-14 and 16-26 and allowed claim 15. (See DE 124-3.) Specifically, the PTO found that "[c]laims 14 and 20 are rejected under 35 U.S.C. 112, second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention." (Id. at 2.) In addition, the PTO rejected a number of claims as being anticipated under 35 U.S.C. § 102(b) or unpatentable under 35 U.S.C. § 103(a) in light of prior art. (See id. at 3-8.) The PTO found that claim 15 was allowable, and this was the sole claim that was included in the '881 patent.
The PTO issued a Notice of Allowance regarding the U.S. patent application on December 7, 2004. (See Exhibit C to DE 59-4.) The '881 patent was issued on May 24, 2005, identifying the claim as follows:
A shape conforming surface covering useful for covering any type of surface, characterized in that the surface covering comprises planks or sheet of flexible material adapted to be interconnected aside of each other thereby forming an assembled surface covering of optional length and width, and which planks are of a material that can be laid in curved formations, and which at the upper surface of the covering is roughened so as to imitate any unique grain effect of wooden material, further characterized in that the planks or sheet are formed with longitudinal slots at the underside thereof for facilitating forming of curved coverings and for acting as a base for a glue or adhesive material by means of which the surface covering is mounted on a surface recipient.
(Exhibit V to DE 52-4.)

4. Relevant Procedural History of this Action

Plaintiffs first took issue with Defendants' discovery failures specific to Defendants' ability to support its affirmative defenses that the '881 patent was invalid on March 30, 2009, when Plaintiffs filed their Motion to Strike Affirmative Defenses [DE 38].[2] In that Motion, Plaintiffs argued that Defendants failed to produce or identify any prior art or documents, other than citing the entire prosecution history, that could support Defendants' affirmative defenses of anticipation and obviousness. *1307 Plaintiffs requested that the Court strike these affirmative defenses, among others, because "Defendants' affirmative defenses state legal theories only with no facts at all to support the claimed defense and do not provide any explanation whatsoever for their assertion." (DE 38 at 9.) Defendants filed a 6-page response arguing that Plaintiffs' Motion was untimely and pointing out that when Plaintiffs contacted Defendants on March 30, 2009[3] to raise the insufficiency of the affirmative defenses, Defendants served Plaintiffs with a Supplement to Defendants' Initial Disclosure. (See DE 45.) The Supplement identified pleadings and attachments filed by another party in a related infringement action involving Plaintiffs in the Southern District of Florida. (See DE 52-15.) In reply, Plaintiffs argued that Defendants misconstrued the Motion to Strike as challenging whether Defendants' affirmative defenses met the "pleading requirements" of the Federal Rules of Civil Procedure, whereas the actual thrust of the motion was to "challenge the adequacy of the Defendants' Initial Disclosures and Discovery Responses." (DE 55 at 1-2.) "Defendants, despite ample opportunity, have declined to support their defenses or at least explain how they apply to the facts of this case." (Id. at 5.)
On June 4, 2009, the Court heard argument on the Motion to Strike, as well as several other pending motions. The Court denied the Motion to Strike given that Defendants' affirmative defenses were at issue in several other motions to be heard by the Court that day, including Plaintiffs' Motion for Summary Judgment [DE 52].
Plaintiffs filed a Motion for Summary Judgment [DE 52] on April 10, 2009. In that Motion, Plaintiffs again attacked Defendants' showing with respect to the affirmative defenses of anticipation and obviousness. "During discovery the Defendants have never disclosed [any] relevant prior art to the '881 patent or one skilled in the prior art who can testify about the affirmative defenses related to Invalidity ...." (DE 52-13 at 6.) By contrast, the Plaintiffs argued that they offered the report of Plaintiffs' expert who compared the available prior art to the '881 patent and concluded that it contained three novel and inventive steps. (Id. at 14.) Defendants responded that it would be improper for the Court to grant summary judgment on the issue of invalidity without first conducting a Markman hearing. (See DE 61 at 4.) Defendants, however, made no attempt to address the merits of the issues of anticipation and obviousness or identify any prior art that would support these affirmative defenses.
At the June 4th hearing mentioned above, the Court conducted a Markman hearing prior to addressing Plaintiffs' Motion for Summary Judgment. Prior to the claim construction hearing, the parties submitted a Joint Statement Regarding Claim Construction [DE 103] which identified 21 discrete terms or phrases contained in the claim embodied in the '881 patent. The parties agreed on 14 terms or phrases and the Court resolved the disputes concerning the remaining 7 at the hearing. The Court then heard argument on Plaintiffs' Motion for Summary Judgment and Defendants failed to present argument or point to evidence on file sufficient to persuade this Court that a reasonable juror could determine that the '881 was invalid on the basis of anticipation or obviousness.
*1308 At the hearing, Defendants did little more than point to the IPONZ decision which found the New Zealand patent to be invalid. However, Defendants did not demonstrate that genuine issues of material fact existed on the issues of anticipation or obviousness in light of the evidence set forth by Plaintiffs. Such evidence included (1) the expert report submitted by Plaintiffs' expert which discussed his review of prior art and his opinion why the '881 patent was valid, (DE 52-12); (2) the testimony of Mr. Abrahamsen that the invention evolved between the issuance of the New Zealand patent and the '881 patent involved in this case, (DE 59-4); and (3) an analysis and chart submitted by Plaintiffs to demonstrate that the prior referenced in the IPONZ decision was "redundant" of prior art that was disclosed to or discovered by the PTO. (DE 59-3 at 10-11.) Accordingly, the Court granted summary judgment in favor of Plaintiffs on the issues of anticipation and obviousness.
On June 14, 2009, literally on the eve of trial, Defendants filed the instant Motion. In the Motion, Defendants identified specific patents and prior art references that allegedly render the '881 patent invalid. In an Order setting a June 16, 2009 hearing on the Motion, the Court acknowledged "that granting a motion for summary judgment on the issue of invalidity is rare," but pointed to the record in the case demonstrating Defendants' continued failure to articulate why the '881 patent is invalid with any degree of particularity. (DE 131 at 1.) The Court went on to state that the "[t]his lack of particularity is not cured in the Defendants' Motion for Reconsideration, although some effort is made. Therefore, the Court will allow Defendants one last opportunity to demonstrate why summary judgment should not be entered." (Id.)
Plaintiffs filed a Response to Defendants' Motion arguing that Defendants cannot meet the standard imposed by Rule 59(e) of the Federal Rules of Civil Procedure because a motion filed pursuant to this rule "cannot be used to relitigate old matters, raise argument or present evidence that could have been raised prior to the entry of judgment." (DE 130 at 6) (citing Arthur v. King, 500 F.3d 1335, 1343 (11th Cir.2007) (emphasis supplied by Plaintiffs)). Plaintiffs assert that "Defendants spend a considerable amount of time in the Motion for Reconsideration attempting to establish a list of prior art that should have been produced in opposition to the motion for summary judgment in order to create [an] issue of fact on the affirmative defense(s) of invalidity well after the time for doing so has passed." (DE 130 at 3.) Further, "Defendants have demonstrated no evidence of reasonable diligence to obtain the documents in the IPONZ proceeding to use in the defense of the summary judgment motions." (Id. at 5.) Therefore, the Response states that the "Plaintiffs should [not] pay, and the Defendants should [not] be rewarded for their lack of diligence." (Id.)

II. LEGAL STANDARD
"The purpose of a motion for reconsideration is to correct manifest errors of law or fact or to present newly discovered evidence.'" Z.K. Marine Inc. v. M/V Archigetis, 808 F.Supp. 1561, 1563 (S.D.Fla. 1992) (quoting Harsco Corp. v. Zlotnicki, 779 F.2d 906, 909 (3d Cir.1985)). "A motion for reconsideration should not be used as a vehicle to present authorities available at the time of the first decision or to reiterate arguments previously made[.]" Id. "In order to reconsider a judgment there must be a reason why the court should reconsider its prior decision, and the moving party must set forth facts or law of a strongly convincing nature to induce *1309 the court to reverse its prior decision." Association For Disabled Americans, Inc. v. Amoco Oil Co., 211 F.R.D. 457, 477 (S.D.Fla.2002).
The Eleventh Circuit has held that "where a party attempts to introduce previously unsubmitted evidence on a motion to reconsider, the court should not grant the motion absent some showing that the evidence was not available during the pendency of the motion." Mays v. United States Postal Serv., 122 F.3d 43, 46 (11th Cir.1997). "Denial of a motion to amend is `especially soundly exercised when the party has failed to articulate any reason for the failure to raise the issue at an earlier stage in the litigation.'" O'Neal v. Kennamer, 958 F.2d 1044, 1047 (11th Cir.1992) (quoting Lussier v. Dugger, 904 F.2d 661, 667 (11th Cir.1990)).

III. ANALYSIS
In a patent infringement action, a district court must approach a motion for summary judgment involving fact issues with "great care." Amhil Enters, v. Wawa, Inc., 81 F.3d 1554, 1557 (Fed.Cir. 1996) (citation omitted). However, summary judgment should be granted "if the pleadings, the discovery and disclosure materials on file, and any affidavits show that there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(c); see also Transclean Corp. v. Bridgewood Servs., 290 F.3d 1364, 1372-73 (Fed.Cir.2002) (affirming summary judgment that a patent was not rendered invalid due to anticipation). A dispute about a material fact is genuine only if "the evidence is such that a reasonable jury could return a verdict for the nonmoving party." Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). A party opposing a properly supported motion for summary judgment "`may not rest upon the mere allegations or denials of his pleading, but... must set forth specific facts showing that there is a genuine issue for trial.'" Id. (quoting First National Bank of Arizona v. Cities Service Co., 391 U.S. 253, 88 S.Ct. 1575, 20 L.Ed.2d 569 (1968)). "If the evidence [opposing summary judgment] is merely colorable, or is not significantly probative, summary judgment may be granted." Anderson, 477 U.S. at 249-250, 106 S.Ct. 2505 (citations omitted). "Summary judgment should be granted when, after an adequate time for discovery, a party fails to make a showing sufficient to establish the existence of an essential element of that party's case." Nolen v. Boca Raton Cmty. Hosp., Inc., 373 F.3d 1151, 1154 (11th Cir.2004) (citing Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986)).
In this case, the Court finds that summary judgment was proper on the issues of anticipation and obviousness because Plaintiffs supported their Motion for Summary Judgment with affirmative evidence and Defendants did not point to specific facts in the record to show that there were genuine issues for trial. In addition, the Court will deny Defendants' Motion to Reconsider, Alter or Amend because of Defendants' repeated failures to explain the basis for, and identify evidence to support, their affirmative defenses.

1. Anticipation and Obviousness

In patent actions, a patent is presumed to be valid and the party challenging a patent's validity has the burden of proving the invalidity by clear and convincing evidence. See 35 U.S.C. § 282; Central Admixture Pharmacy Services, Inc. v. Advanced Cardiac Solutions, P.C., 482 F.3d 1347, 1357-58 (Fed.Cir.2007) (citing U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1564 (Fed.Cir.1997)). "Our *1310 precedent holds that the presumption of validity afforded a U.S. patent by 35 U.S.C. § 282 requires that the party challenging validity prove the facts establishing invalidity by clear and convincing evidence." Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed.Cir. 1987) (citations omitted).
"A prior art reference anticipates a patent claim if the reference discloses, either expressly or inherently, all of the limitations of the claim." Finnigan Corp. v. International Trade Com'n, 180 F.3d 1354, 1365 (Fed.Cir.1999); accord Continental Can Co. v. Monsanto Co., 948 F.2d 1264, 1268 (Fed.Cir.1991) ("Anticipation... requires that the identical invention that is claimed was previously known to others and thus is not new."). "Anticipation is a question of fact, including whether or not an element is inherent in the prior art." Eli Lilly & Co. v. Zenith Goldline Pharms., Inc., 471 F.3d 1369, 1375 (Fed. Cir.2006).
In order to show that a claim is invalid due to obviousness, the challenger must prove that the differences between the invention and the prior art "are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains." 35 U.S.C. § 103(a). Whether the invention was obvious under § 103 is to be determined by the following analysis:
Under § 103, the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue are to be ascertained; and the level of ordinary skill in the pertinent art resolved. Against this background the obviousness or nonobviousness of the subject matter is determined. Such secondary considerations as commercial success, long felt but unsolved needs, failure of others, etc., might be utilized to give light to the circumstances surrounding the origin of the subject matter sought to be patented.
Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 17-18, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966): see also KSR Intern. Co. v. Teleflex Inc., 550 U.S. 398, 406-07, 127 S.Ct. 1727, 167 L.Ed.2d 705 (2007).

2. Summary Judgment was Warranted in the First Instance

As discussed above, in opposing summary judgment, Defendants failed to identify to this Court specific items of prior art that allegedly render the '881 patent invalid. Defendants merely referred this Court to the IPONZ decision and pleadings submitted in another action, which included the Smithers Rapra Report [DE 45-3],[4] without any explanation or application to the '881 patent. Defendants' effort to support its affirmative defenses of anticipation and obviousness was deficient for a number of reasons.
First, neither the IPONZ decision nor the Smithers Rapra Report deals with the '881 patent. The IPONZ decision concerns the New Zealand patent and the Smithers Rapra Report analyzes the International Patent. This is particularly significant because the aforementioned patents were the basis for the initial U.S. patent application submitted by Flexiteek International, which was rejected by the PTO. It was not until Flexiteek International amended the U.S. patent application *1311 and resubmitted it in September of 2004 that the PTO allowed a single claim to ultimately be embodied in the '881 patent.
Second, courts in the United States should exercise caution in according weight to a decision from a foreign patent office, which uses different procedures, standards and laws. See Heidelberger Druckmaschinen AG v. Hantscho Comm'l Prods., Inc., 21 F.3d 1068, 1072 (Fed.Cir. 1994). The IPONZ decision not only analyzes a different patent, but does so under a different set of laws than those applicable to the '881 patent. These factors diminish the probative value of the IPONZ decision. In addition, Defendants' attempts to demonstrate that their affirmative defenses of anticipation and obviousness created genuine issues for trial consisted primarily of arguing for a wholesale adoption of the conclusions reached in the IPONZ decision, rather than an independent analysis of the available prior art and the '881 patent. Accordingly, the Court had serious concerns of regarding the admissibility of the IPONZ decision under Rule 403 of the Federal Rules of Evidence. Evidence must be admissible at trial or capable of being presented in admissible form at trial to be considered on a motion for summary judgment. Fed.R.Civ.P. 56(e); Denney v. City of Albany, 247 F.3d 1172, 1189 n. 10 (11th Cir.2001).
Third, Defendants did not submit an expert report analyzing the '881 patent and the available prior art. "What a prior art reference discloses or teaches is determined from the perspective of one of ordinary skill in the art." Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1361 (Fed.Cir.2008). Further, "[w]hether a patent claim would have been obvious in light of prior art references is determined from the perspective of one of ordinary skill in the art." Id. Defendants submitted an expert report of Mark L. Weber entitled "Infringement Analysis," which focused on the issue of infringement and did not address Defendants' affirmative defenses of anticipation and obviousness. Moreover, the Court granted Plaintiffs' Motion in Limine [DE 92] and excluded testimony from Mr. Weber during the jury trial. In opposing that Motion, Defense counsel acknowledged that Mr. Weber was not "one of ordinary skill in the art."
Fourth, 35 U.S.C. § 282 provides that:
In actions involving the validity or infringement of a patent the party asserting invalidity or noninfringement shall give notice in the pleadings or otherwise in writing to the adverse party at least thirty days before the trial, of the country, number, date, and name of the patentee of any patent, the title, date, and page numbers of any publication to be relied upon as anticipation of the patent in suit or ... as showing the state of the art, and the name and address of any person who may be relied upon as the prior inventor or as having prior knowledge of or as having previously used or offered for sale the invention of the patent in suit. In the absence of such notice proof of the said matters may not be made at the trial except on such terms as the court requires.
35 U.S.C. § 282. On May 22, 2009, Plaintiffs filed a Motion in Limine [DE 92] in which they argued "[a]t this stage of the proceedings, the Plaintiff still does not know which prior art references the Defendants will be relying on to carry their burden of proof, by clear and convincing evidence," with respect to Defendants' affirmative defenses related to invalidity. (DE 92 at 14.) On June 9, 2009, Defendants responded to Plaintiffs' Motion in Limine and cited specifically to prior art referred to by the PTO and IPONZ, which Defendants intended to rely on in support *1312 of their affirmative defenses. Due to the fact that the trial in this action began on June 15, 2009, the Court finds that Defendants failed to comply with 35 U.S.C. § 282.
Conversely, Plaintiffs set forth affirmative evidence to establish that the '881 patent was valid. Plaintiffs' submitted an expert report in which Plaintiffs' expert identifies 3 elements of the '881 patent that were not rendered invalid by the prior art available at the time the patent was issued, including prior art referenced in the IPONZ decision. The elements identified in the report are:
1. The underside surface has a longitudinal structure, which, in conjunction with the material of the invention, facilitates curved formations.
2. The side interconnections are configured or adapted to curve with the sheets or planks once joined.
3. The upper surface of the side interconnections are roughened or modeled to resemble caulking strips, rubber seams or the like, between planks of wood.
(DE 52-12 ¶¶ 44, 47-48.) Dr. Rhee found that the foregoing did not appear in any of the available prior art and, therefore, these are novel or inventive steps of the '881 patent, "and represent a significant improvement over the inventions of the prior art." (Id. ¶ 51.) "[T]he combination of the previously known elements ... along with the novel or inventive steps, which significantly increased the applications of the invention to the purpose of synthetic teak decking for a boat was not obvious." (Id. ¶ 52.)
Plaintiffs also submitted the Declaration of Svein Abrahamsen that stated that "since the New Zealand patent was granted in September 23, 2002, there was a substantial change in the technology of synthetic teak decking products which made the claims in the New Zealand patent outdated." (DE 59-4 ¶ 10.) Finally, the Plaintiffs filed a chart and analysis to show that the prior art that appeared or was referenced by the IPONZ decision was "redundant" of the prior art that had either been disclosed to or discovered by the patent examiner of the U.S. patent application. (DE 59-3 at 10-11.)
Therefore, the Court holds that in light of the record before it at the time, the entry of summary judgment on the issues of anticipation and obviousness was not a "manifest error."

3. Defendants' Motion Provides an Insufficient Basis for this Court to Reconsider. Alter or Amend its Order

The Defendants' Motion to Reconsider, Alter or Amend cites to a number of prior art references in support of Defendants' affirmative defenses of anticipation and obviousness. (See DE 124 at 5-6.) As mentioned, Defendants' Response to Plaintiffs' Motion in Limine also cites several patents that purportedly render the '881 patent invalid. However, what is lacking is an explanation why such patents were not identified and discussed in response to Plaintiffs' Motion to Strike or Plaintiffs' Motion for Summary Judgment. See O'Neal, 958 F.2d at 1047 ("Denial of a motion to amend is especially soundly exercised when the party has failed to articulate any reason for the failure to raise the issue at an earlier stage in the litigation.") (quotation omitted). Defendants also had a duty under 35 U.S.C. § 282 to give notice to Plaintiffs of the specific prior art references Defendants intended to rely on.
At a minimum, Defendants were aware of the IPONZ decision on March 30, 2009, (see DE 52-15), and had access to the documents Plaintiffs' expert reviewed as of April 30, 2009, when they took his deposition. *1313 (See DE 118 at 11.) Defendants' Response to Plaintiffs' Motion in Limine argues that Plaintiffs did not suffer any prejudice because Plaintiffs were aware of such documents and in fact their expert had reviewed them. The Court disagrees.
"The objective of section 282's provision for advance notice is to prevent unfair and prejudicial surprise by the production of unexpected and unprepared-for prior art references at trial." Eaton Corp. v. Appliance Valves Corp., 790 F.2d 874, 879 (Fed. Cir.1986). "What counts is notice of intent to rely. Therefore, as a general rule, merely mentioning a prior patent or publication in a pre-trial paper, and neglecting to indicate that it will be used at trial, does not normally constitute adequate notice." Id. at 879. Plaintiffs' expert cited at least 32 patents that he reviewed in addition to the IPONZ decision and the Smithers Rapra Report. (See Ex. B to DE 47.) Plaintiffs' expert also submitted a report explaining his reasoning as to why the '881 patent was valid months before the trial. The Court finds that to allow Defendants to remain silent until the eve of trial as to (1) the specific prior art references they intended to rely upon, and (2) their reasoning as to why such references render the '881 patent invalid would provide Defendants with an unfair advantage. Cf. Eaton, 790 F.2d at 880 (affirming a district court's determination to allow in evidence of undisclosed prior art where the district court found "no prejudice whatsoever").
During the course of oral argument on June 16, 2009, Defense counsel asserted that Defendants could not fully address the issues of anticipation or obviousness until this Court conducted the claim construction on June 4, 2009. However, the timing of the claim construction did not preclude Defendants from identifying and producing relevant prior art during the course of discovery. Nor did it preclude Defendants from addressing the arguments and evidence Plaintiffs set forth on the record regarding the validity of the '881 patent.
Defendants also argue that § 282 "should be interpreted in light of the permissive nature of Fed.R.Civ.P. 26 regarding relevant evidence." (DE 118 at 9) (citing Eaton, 790 F.2d at 880). However, the Court's decision is reinforced by the fact that not only did Defendants have an affirmative duty under § 282 to identify the prior art, but Plaintiffs filed two separate motions seeking such information. In light of these circumstances, it is not enough for Defendants to argue that Plaintiffs were aware of the universe of documents upon which Defendants might introduce at trial. ATD Corp. v. Lydall, Inc., 159 F.3d 534, 551 (Fed.Cir.1998) (affirming decision to exclude prior art where party "offered no reason to justify its submission long after the close of discovery"). Moreover, this Court informed the parties on May 8, 2009 that it expected "strict compliance with the Local Rules and the Rules of Federal Procedure going forward." (DE 77 at 2.) Therefore, the Court will deny Defendants' Motion to Reconsider, Alter, or Amend.
For the foregoing reasons, it is hereby
ORDERED AND ADJUDGED that Defendants' Motion to Reconsider, Alter or Amend Order Granting in Part Plaintiffs' Motion for Summary Judgment [DE 124] is DENIED.
NOTES
[1]  The Court will briefly state its holding on the issue of standing in light of the extensive argument before the Court on these matters and in order to facilitate the mediation that the parties will be conducting on June 5, 2009, The Court's reasoning on this matter will be fully-articulated in an ensuing Order Denying Defendants' Renewed Motion to Dismiss.
[2]  Apart from a statement in Defendants' Answer [DE 8], which reads "Plaintiffs' claims are barred because of Plaintiffs' laches," Defendants have not placed a scintilla of evidence or argument before this Court to support this defense. Accordingly, Defendants' affirmative defense of laches will be summarily dismissed.
[3]  To be considered on a motion for summary judgment, evidence must be admissible at trial or capable of being presented in admissible form at trial. Fed.R.Civ.P. 56(e); Denney v. City of Albany, 247 F.3d 1172, 1189 n. 10 (11th Cir.2001). The Court has considered the IPONZ Decision in connection with Plaintiffs' Motion because it may be admissible at trial. But Defendants should not construe this decision as a finding that Federal Rules of Evidence regarding admissibility or authentication have been waived by Plaintiffs for the purposes of trial.
[1]  This Order corrects a typographical error contained on page 18 of the original order which stated that "a hearing on" the instant Motion is denied. This Order removes the words "a hearing on" to clarify that the instant Motion is denied.
[2]  Although this Order focuses on the inadequacy of Defendants' disclosure regarding anticipation and obvious, the Court notes that were also deficiencies on the part of the Plaintiffs in the course of this litigation. After a contentious discovery period, during which a number of motions were filed by both sides, the Court entered an Order Denying Motions to Strike [DE 77] on May 8, 2009, 2009 WL 1288562. After noting violations of the Local Rules, but declining to strike the parties' submissions, the Court stated: "The parties should consider themselves warned. This Court will expect strict compliance with the Local Rules and the Rules of Federal Procedure going forward." (DE 77 at 2.) In this regard, the Court capped the potential damages Plaintiffs could receive and precluded Plaintiffs from arguing infringement under the doctrine of equivalents due to untimely disclosures.
[3]  The Scheduling Order [DE 11] in this action directed that fact discovery was to be completed as of March 13, 2009 and expert discovery was to be completed by March 27, 2009.
[4]  The Smithers Rapra Report appears to be technical report prepared for the defendants in the related action discussing the invalidity of the International Patent W/O 01/00948 A1 for a "Shape Conforming Surface Covering" ("International Patent"). (See DE 45-3 at 24.)
