       McKEAGUE, Circuit Judge. Z Technologies alleges that The Lubrizol Corporation
violated the Sherman, Clayton, and analogous state-law antitrust acts by raising prices and
enforcing a non-compete clause following Lubrizol’s acquisition of the assets of another

company, which established a monopoly in the market for petroleum wax-based oxidates.
Lubrizol moved to dismiss the claim on the pleadings. The primary question presented on appeal
is whether Z Technologies’s claims are barred by the statute of limitations. Z Technologies
contends that the continuing violations and hold-and-use doctrines extend the statute of
limitations on the Sherman and Clayton Acts, respectively. The district court rejected the
continuing-violations argument after determining that the increase in prices by Lubrizol and the
alleged implementation of a non-compete clause did not constitute a “new and independent”
injury.    The district court likewise found the hold-and-use argument inapplicable because
Lubrizol’s alleged implementation of a non-compete clause from the acquisition agreement was
not a “new use” of an “asset” extending the statute of limitations. As the district court correctly
rejected Z Technologies’s continuing-violations and hold-and-use arguments, we AFFIRM.

                                       I. BACKGROUND

          The Lubrizol Corporation is a chemical manufacturer that produces petroleum wax-based
oxidates, which are used to create anti-corrosion products. Z Technologies is a purchaser of such
oxidates and makes anti-corrosion products for car manufacturers.          On February 7, 2007,
Lubrizol acquired the Lockhart Company’s (“Lockhart”) oxidate business and oxidate assets.
This acquisition left Lockhart’s oxidate production facility in Flint, Michigan (“the Flint Plant”)
partially unused.

          As part of the purchase agreement, Lockhart agreed to a non-compete clause that
“prohibited Lockhart, for a period of five years from the date of the purchase agreement, from
directly or indirectly engaging in any business competitive with the assets it sold to Lubrizol.”
Though it is not clear how or when it happened, Lubrizol allegedly later employed the non-
compete clause “to prevent the use or re-lease of the [Flint Plant] to another oxidates
manufacturer.”

          All the parties agree that the purchase of Lockhart provided Lubrizol with a monopoly in
the oxidate market. At the time of the acquisition, Lubrizol and Lockhart together accounted for
98% of oxidate sales in the United States. After acquiring Lockhart, Lubrizol increased prices
for oxidates in March, July, and November of 2007, and again in May, July, and September of
2008. These increases taken together raised the price of oxidates by approximately 70%.
No. 13-1254                Z Tech. Corp. v. Lubrizol Corp.                                         Page 3

         Following the price increases, on February 26, 2009, the Federal Trade Commission
brought a complaint alleging that, by acquiring Lockhart, Lubrizol created a monopoly in the
oxidate market for rust-preventative additives and thereby violated Section 5 of the Federal
Trade Commission Act and Section 7 of the Clayton Act. On April 7, 2009, Lubrizol entered
into a consent agreement with the Federal Trade Commission in which Lubrizol promised: (1) to
divest the oxidates assets acquired from Lockhart to a third company, Additives International,
Inc.; (2) to “remove and rescind any prohibition or restraint including . . . any noncompete
agreements, on the sale or use of all or any part of respondent Lockhart’s Flint Plant for the
manufacture and sale of any products produced at the Flint Plant by Additives International or
any other person;” and (3) to lease the Flint Plant to Additives International.

         Z Technologies filed its Complaint on May 18, 2012. The Complaint alleged, among
other things, that Lubrizol had violated the Sherman and Clayton Acts and Michigan antitrust
laws by purchasing Lockhart’s oxidate business and obtaining a monopoly in the oxidate-
production market. On August 17, 2012, Lubrizol filed a motion to dismiss the First Amended
Complaint for failure to state a claim upon which relief might be granted, and on February 5,
2013, the district court granted the motion after determining that all of the claims were time-
barred. Z Technologies appeals the dismissal.

                                                  II. ANALYSIS

         All of Z Technologies’s claims, including the Sherman Act, Clayton Act, and Michigan
Antitrust claims, are subject to a four-year and forty-day statute of limitations.1 See 15 U.S.C.
§ 15b (“Any action to enforce any cause of action under section 15, 15a, or 15c of this title shall
be forever barred unless commenced within four years after the cause of action accrued. No
cause of action barred under existing law on the effective date of this Act shall be revived by this
Act.”); Mich. Comp. Laws §§ 445.781, 445.784(2) (2009) (“It is the intent of the legislature that

         1
           As previously discussed, the Federal Trade Commission filed a complaint against Lubrizol on February
26, 2009, and then resolved the complaint by consent decree on April 7, 2009. The statute of limitations is generally
suspended during the pendency of any civil or criminal proceeding instituted by the United States, and Z
Technologies argues that this forty-day period should be added to the statute of limitations under 15 U.S.C. § 16(i).
See Yoder Bros., Inc. v. California-Florida Plant Corp., 537 F.2d 1347, 1361 (5th Cir. 1976) (“The tolling provision
of the statute has the effect of giving antitrust plaintiffs a period of four years plus the length of the Government suit
for which they can recover.”). Assuming Z Technologies is correct and the forty days should be added, we are
presented with a statute of limitations of four years and forty days.
No. 13-1254            Z Tech. Corp. v. Lubrizol Corp.                               Page 4

in construing all sections of this act, the courts shall give due deference to interpretations given
by the federal courts to comparable antitrust statutes, including, without limitation, the doctrine
of per se violations and the rule of reason.”); see also DXS, Inc. v. Siemens Med. Sys., Inc., 100
F.3d 462, 467 (6th Cir. 1996).

        Lubrizol acquired Lockhart’s oxidate business on February 7, 2007, and Z Technologies
filed its Complaint on May 18, 2012, approximately five years and three months later. At first
glance, Z Technologies’s claims appear to be barred by the statute of limitations. The primary
question presented on appeal, then, is whether Lubrizol’s conduct subsequent to the acquisition,
including charging “supra-competitive” prices and enforcing a non-compete clause from the
acquisition agreement, retriggered the date from which the statute of limitations is measured.
We assess this question claim by claim.

    1. Standard of Review

        This court reviews de novo a district court’s ruling granting a motion to dismiss under
Federal Rule of Civil Procedure 12(b)(6). Dubay v. Wells, 506 F.3d 422, 427 (6th Cir. 2007).
When reviewing pleadings, “we do not require heightened fact pleading of specifics, but only
enough facts to state a claim to relief that is plausible on its face.” Bell Atl. Corp. v. Twombly,
550 U.S. 544, 570 (2007). “A claim has facial plausibility when the plaintiff pleads factual
content that allows the court to draw the reasonable inference that the defendant is liable for the
misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009).

        “In deciding whether to grant a Rule 12(b)(6) motion, we must construe the complaint in
the light most favorable to the plaintiff, accept all factual allegations [of the plaintiff] as true, and
determine whether the plaintiff undoubtedly can prove no set of facts in support of his claims
that would entitle him to relief.” Ricco v. Potter, 377 F.3d 599, 602 (6th Cir. 2004) (internal
citation and quotation marks omitted). “Although this standard for Rule 12(b)(6) dismissals is
quite liberal, more than bare assertions of legal conclusions is ordinarily required to satisfy
federal notice pleading requirements.” Advocacy Org. for Patients & Providers v. Auto Club Ins.
Ass’n, 176 F.3d 315, 319 (6th Cir. 1999) (internal citation and quotation marks omitted).
No. 13-1254               Z Tech. Corp. v. Lubrizol Corp.                                       Page 5

    2. Sherman Act Claim

         Z Technologies first alleges a violation of Section 2 of the Sherman Antitrust Act,
15 U.S.C. § 2. The district court determined that the statute of limitations prevented the claim
from proceeding. We agree.

         The Sherman Antitrust Act makes it an offense to “monopolize, or attempt to
monopolize, or combine or conspire with any other person or persons, to monopolize any part of
the trade or commerce among the several States.” Id. Claims brought under the Act are subject
to a four-year statute of limitations from the date “the cause of action accrued.” Id. § 15b; see
also Zenith Radio Corp. v. Hazeltine Research Inc., 401 U.S. 321, 338 (1971).

         Z Technologies alleges a “continuing antitrust” violation; that is, a violation where
Z Technologies’s interests “[we]re repeatedly invaded.” Peck v. Gen. Motors Corp., 894 F.2d
844, 849 (6th Cir. 1990) (per curiam). When a continuing violation occurs, “the statute of
limitations runs from the commission of the act that causes the plaintiff’s damage.” Id. As the
Peck court further clarified, “even when a plaintiff alleges a continuing violation, an overt act by
the defendant is required to restart the statute of limitations and the statute runs from the last
overt act.”     Id. (emphasis added) (internal citation and quotation marks omitted).                        Before
assessing, however, whether the overt act requirement has been satisfied in the present case, we
must determine whether the continuing violations doctrine even applies to price increases
following a merger or acquisition. We conclude that it does not.

              A. The Continuing Violations Doctrine Does Not Apply to Price Increases
                 Following a Merger or Acquisition

         Z Technologies argues that the continuing violations doctrine applies to a price increase
following a merger or acquisition.2 There is simply no support for this contention. With only
two exceptions, all of the cases cited by Z Technologies in which a price increase extended the


         2
          Z Technologies discusses extensively two district court cases, In re Skelaxin (Metaxalone) Antitrust Litig.,
No. 1:12-md-2343, 2013 WL 2181185, at *27–29 (E.D. Tenn. May 20, 2013), and In re Wholesale Grocery
Products Antitrust Litig., 722 F. Supp. 2d 1079, 1086–89 (D. Minn. 2010). As both of these cases involved price
increases brought in conspiracy claims, not in merger monopolization or unilateral monopolization claims, they
provide little guidance as to whether price increases that are not the result of two companies conspiring together
should be treated as an overt act.
No. 13-1254               Z Tech. Corp. v. Lubrizol Corp.                                       Page 6

statute of limitations involved antitrust conspiracy claims,3 and the excepted cases involved
monopolization claims where a party unilaterally monopolized a market or undertook action, in
addition to price increases, to monopolize a market.4 None of the cited cases indicate that a price
increase following a merger or acquisition, by itself, extends the statute of limitations.
         The focus on conspiracy cases for a continuing violations offense makes intuitive sense.
In a conspiracy, each price increase requires further collusion between multiple parties to
maintain the monopoly; in a merger-acquisition case, however, the cause of harm is the merger
itself. The subsequent price increases do not further the company’s monopoly because the
company has already obtained the monopoly.

         Observations from our sister circuits, as well as limited guidance from the Supreme
Court, support our conclusion that price increases in the merger-acquisition context do not
extend the statute of limitations. In Concord Boat Corp. v. Brunswick Corporation, the Eighth
Circuit noted that “[c]ontinuing violations have not been found outside the RICO5 or Sherman
Act conspiracy context . . . because acts that simply reflect or implement a prior refusal to deal or
acts that are merely unabated inertial consequences (of a single act) do not restart the statute of
limitations.”     207 F.3d 1039, 1052 (8th Cir. 2000) (internal citation and quotation marks
omitted).     Similarly, while the Supreme Court has never directly limited the scope of the
continuing violations doctrine, it appears to have employed the doctrine only in conspiracy and

Lower Lake Erie Iron Ore Antitrust Litig., 998 F.2d 1144, 1171–72 (3d Cir. 1993) (conspiracy by several railroads);
In re Skelaxin (Metaxalone) Antitrust Litig., 2013 WL 2181185, at *6–10 (conspiracy to restrain trade); In re
Wholesale Grocery Prods. Antitrust Litig., 722 F. Supp. 2d at 1082–83 (market and customer allocation conspiracy);
Molecular Diagnostics Labs. v. Hoffmann-La Roche Inc., 402 F. Supp. 2d 276, 278–79 (D.D.C. 2005) (conspiracy
to maintain monopoly); In re K-Dur Antitrust Litig., 338 F. Supp. 2d 517, 525–26 (D.N.J. 2004) (conspiracy to
restrain trade by delaying release of generic drug); In re Buspirone Patent Litig., 185 F. Supp. 2d 363, 365–67
(S.D.N.Y. 2002) (conspiracy to restrain trade by listing nonapplicable patent); In re Nine West Shoes Antitrust Litig.,
80 F. Supp. 2d 181, 183–85 (S.D.N.Y. 2000) (price-fixing conspiracy).
         4
          The first case cited by Z Technologies that does not involve a conspiracy claim is Meijer, Inc. v. 3M, No.
04-5871, 2005 WL 1660188 (E.D. Pa. July 13, 2005), but that case involved an attempt to maintain a monopoly by
charging supra-competitive prices to suppress competition, not a merger acquisition resulting in a monopoly like in
the present action. Id. at *4. The second case is Free FreeHand Corp. v. Adobe Systems Inc., 852 F. Supp. 2d 1171
(N.D. Cal. 2012). There, contrary to Z Technologies’s contention, the district court did not extend the statute of
limitations solely on the basis of price. Instead, the district court determined that ceasing development of software,
channeling existing customers to a different software, and bundling software constituted new post-merger acts that
extended the statute of limitations. Id. at 1187. These types of overt acts that the district court relied upon in Free
FreeHand are absent in the present case.

monopolization cases not involving mergers or acquisitions. See, e.g., Klehr v. A.O. Smith
Corp., 521 U.S. 179, 189 (1997) (RICO conspiracy where the Court observed “in the case of a
‘continuing violation,’ say, a price fixing conspiracy that brings about a series of unlawfully high
priced sales . . . each sale to the plaintiff, starts the statutory period running again” (emphasis
added) (internal quotation marks omitted)); Zenith, 401 U.S. at 338–39 (involving a “continuing
conspiracy to violate the antitrust laws”); Hanover Shoe, Inc. v. United Shoe Mach. Corp.,
392 U.S. 481, 483–84 (1968) (applying continuing violations doctrine in a monopolization case
not involving merger or acquisition); see also Phillip Areeda and Herbert Hovenkamp, Antitrust
Law: An Analysis of Antitrust Principles and Their Application, ¶ 320, 297 (3d ed. 2007)
(“While the cases are not consistent, they are significantly more likely to restart the statute when
the action complained of is conspiratorial rather than unilateral.”).

        Similarly, this court has applied the continuing violations doctrine only to conspiracy
claims, see, e.g., Peck, 894 F.2d at 849; Barnosky Oils, Inc. v. Union Oil Co. of Cal., 665 F.2d
74, 81 (6th Cir. 1981), and to unilateral monopolization claims when a party already possesses a
monopoly and takes action to preserve the monopoly, see, e.g., DXS, 100 F.3d at 467. We have
not discovered a case, let alone a Sixth Circuit authority, nor has Z Technologies identified one,
in which the continuing violations doctrine has been applied to price increases following a
merger or acquisition. Taken altogether, it is clear from the complete absence of supporting case
law that the continuing violations doctrine does not apply to such claims.

        B. Price Increases Are Not Overt Acts

        Assuming arguendo, however, that the continuing violations doctrine does apply to a
price increase following a merger or acquisition, the question still arises whether the price
increases in the present case constitute “overt acts” that extend the statute of limitations. Again,
Sixth Circuit precedent, leading antitrust commentators, and case law from our sister circuits all
indicate that price increases in the merger-monopolization context are not “overt acts” extending
the statute of limitations.
No. 13-1254           Z Tech. Corp. v. Lubrizol Corp.                              Page 8

              i. Under Sixth Circuit precedent, price increases are not overt acts.

       Our Sixth Circuit cases clearly indicate that price increases following a merger or
acquisition are not overt acts. The most important tenet of the Sixth Circuit’s continuing
violations doctrine is that “a newly accruing claim for damages must be based on some injurious
act actually occurring during the limitations period, not merely the abatable but unabated inertial
consequences of some pre-limitations action.” Barnosky Oils, 665 F.2d at 81 (internal citation
and quotation marks omitted). Put more simply, an overt act “(1) . . . must be a new and
independent act that is not merely a reaffirmation of a previous act; and (2) . . . must inflict a new
and accumulating injury on the plaintiff.” DXS, 100 F.3d at 467 (internal citation and quotation
marks omitted). Based upon this principle, the Sixth Circuit has repeatedly rejected invocations
of the continuing-violations defense that are mere reaffirmations of a previous act.

       This principle was first expressed in Barnosky Oils, Inc., v. Union Oil Company of
California. There, we rejected the argument that a seller, who “benefitted” from later sales made
under an anticompetitive contract, was not protected by the statute of limitations because of the
continuing violations doctrine:

       That [the plaintiff] may have suffered, and [the defendant] may have benefitted,
       from the consequences of [the defendant’s] conduct during the limitations period
       does not render the act a continuing violation of the antitrust laws. The
       ‘unabated inertial consequences’ of the 1971 contract are qualitatively distinct
       from the acts that gave rise to continually accruing causes of action . . . .

Barnosky Oils, 665 F.2d at 82 (emphasis added) (internal citation and quotation marks omitted).
More recently, in Grand Rapids Plastics, Inc., v. Lakian, this court again declined to apply the
continuing violations doctrine because “even if the payment agreement [which permitted
payment of unlawful commissions] constituted a continuing violation . . . the individual
payments to [the defendant] were only a manifestation of the previous agreement.                 The
individual payments therefore do not constitute a ‘new and independent act,’ as required to
restart the statute of limitations.” 188 F.3d 401, 406 (6th Cir. 1999).

       Thus, while none of the cases address price increases per se, our decisions have
repeatedly emphasized that profits, sales, and other benefits accrued as the result of an initial
wrongful act are not treated as “independent acts.” Rather, they are uniformly viewed as
No. 13-1254           Z Tech. Corp. v. Lubrizol Corp.                             Page 9

“ripples” caused by the initial injury, not as distinct injuries themselves. See e.g., Peck, 894 F.2d
at 849 (rejecting a continuing violations defense even though plaintiffs alleged they had felt the
adverse impact of the defendant’s conspiracy within the timeframe permitted by the statute of
limitations); Eichman v. Fotomat Corp., 880 F.2d 149, 160 (9th Cir. 1989) (“[R]eceipt of profits
from an illegal contract by an antitrust defendant is not an overt act of enforcement which will
restart the statute of limitations.”). There is no compelling reason to treat profits derived from a
price increase differently.

       Each of the cases discussed so far have involved a determination that the defendant’s
conduct did not constitute an independent action for continuing violations purposes. It is helpful
therefore to review what has been considered an independent violation. In DXS, Inc. v. Siemens
Medical Systems, Inc., for example, Siemens, which both sold and serviced x-ray equipment,
established a policy restricting third-party maintenance of equipment originally manufactured by
Siemens. 100 F.3d at 467–68. Almost two years after nominally creating the policy, Siemens
made misrepresentations to several hospitals regarding its warranties and thereby harmed the
plaintiff, a third-party service provider. Id. On review, we found that the plaintiff’s claims were
not time barred after determining that the continuing violations doctrine applied. Id. To reach
this conclusion, the court assessed whether a series of letters sent to local hospitals by Siemens to
convince them to abandon the competing third-party servicer were mere “reaffirmations” of the
previously announced policy or constituted a “new and independent act.” Id. We found that
they were “new and independent” because the previously announced policy had not been “final”
and had not been enforced for two years. Id.

       The present case is clearly distinct from the situation presented in DXS. While DXS
involved a policy shift and “new” conduct designed to further a monopolistic goal, here the only
conduct complained of were the price increases. No new or subsequent action was undertaken to
obtain a monopoly because one had already been accomplished and, as the DXS court
acknowledged, “[i]f, as the district court assumed, Siemens had implemented its new policies
from the date of the [original policy], then the court might have been correct in concluding that
Siemens’s statements were merely effects of the [original policy] that caused no new injury to
DXS.” Id. at 468. The conduct at issue in this case falls squarely within this illustration. There
No. 13-1254              Z Tech. Corp. v. Lubrizol Corp.                                  Page 10

is no question that the ability to affect market prices arising out of the acquisition of Lockhart’s
oxidate business was complete at the time of the merger. Thus, under DXS and in light of other
Sixth Circuit case law indicating that benefits and profits derived from wrongful conduct are not
“independent” overt acts but, rather, reaffirmations of a previous act, we conclude that price
increases do not constitute overt acts for purposes of the continuing violations doctrine.

               ii. Leading antitrust commentators and other circuits also indicate that price
                   increases, like those that occurred in this case, are not overt acts.

        Our conclusion that price increases, such as the ones that occurred in this case, are not
overt acts is supported by leading commentators and our sister circuits. It is axiomatic that
horizontal mergers,6 such as the one that took place in the present case, lead to a concentrated
market position and enable the merged company to reduce output and to raise prices. See
Antitrust, ¶ 320, at 288. As Professor Areeda explains:

        [I]t would seem that high prices following an anticompetitive merger or the
        creation of a monopoly are mere ‘inertial consequences’ that one naturally
        expects to flow from such acts. An automatic and thus ‘inertial’ consequence of a
        merger is the making of subsequent sales. By contrast, a series of ongoing
        meetings to correct a cartel and adjust its prices is hardly ‘inertial,’ but manifest a
        commitment to renewing the competitive act. Most of the decisions are consistent
        with these observations.

Id. (emphasis added). “If the mere charging of a monopoly price constitutes a ‘continuing
violation’ tolling the statute, then we have indefinitely lengthened the statute of limitation on
claims of successful monopolization,” id. at 286, and in the process, eliminated repose for the
merged party contrary to congressional intent.

        This precise point was also made by the Eighth Circuit in Midwestern Machinery Co. v.
Northwest Airlines, albeit in the context of a merger claim brought under § 7 of the Clayton Act,
which governs mergers or acquisitions resulting in monopolization. 392 F.3d 265, 269 (8th Cir.
2004). In that case, following the merger of Northwest Airlines and Republic Airlines, the
plaintiffs alleged that Northwest charged a “hub premium,” essentially a price increase for flights

          Horizontal mergers occur when “one firm acquires another firm that produces and sells an identical or
similar product in the same geographic area, and thereby eliminates competition between the two firms.” 3 West’s
Fed. Admin. Prac. § 3067. “[U]nification of the merging firms’ operations may create substantial market power and
could enable the merged entity to raise prices by reducing output unilaterally.” Id. § 3068.
No. 13-1254               Z Tech. Corp. v. Lubrizol Corp.                                     Page 11

through the Minneapolis-St. Paul Airport, and that its action constituted a continuing violation
allowing the plaintiff to avoid the statute of limitations bar. Id. The court rejected this argument
explaining,

         If the initial violation was the merger itself, none of the “continuing violations”
         [the plaintiff] alleges can justify restarting the statute of limitations because these
         acts were not undertaken to further an illegal policy of merger or to maintain the
         merger . . . . Once the merger is completed, the plan to merge is completed, and
         no overt acts can be undertaken to further that plan.
         Unlike a conspiracy or the maintaining of a monopoly, a merger is a discrete act,
         not an ongoing scheme. . . . Even if the initial merger violated § 7, it makes little
         sense to hold that policies were pursued to effectuate the illegal merger as we
         might in a case involving a conspiracy violating § 1 (e.g., cartel meetings
         occurred to effectuate a price-fixing agreement) or a case violating § 2 (e.g.,
         ongoing policy of predatory pricing undertaken to effectuate monopolization).
         Once a merger is completed, there is no continuing violation possible under § 7
         that would justify extending the statute of limitations beyond four years.

Id. at 271 (emphasis added). Z Technologies argues that the above language, which strongly
indicates that a merger is a discrete act and that subsequent price increases are not overt acts,
should not be considered because Midwestern Machinery involved a Clayton Act claim, while
the present claim arises under the Sherman Act.7

         Although it is true that the Sherman Act regulates a broader swath of conduct than the
Clayton Act, the claim in the present case is for an acquisition-merger monopoly, which is the
precise conduct governed by the Clayton Act. There is no reason to treat the same conduct
differently in sister statutes that are designed to promote the same legislative objective.
Moreover, the same statute—15 U.S.C. § 15b—provides the statute of limitations for each.
There is nothing in 15 U.S.C. § 15b that suggests it should be applied one way for merger-
acquisition claims under the Sherman Act but differently for merger-acquisition claims under the
Clayton Act.


         7
          Admittedly, there is dicta in Midwestern Machinery suggesting that the continuing violations doctrine
should remain viable under the Sherman Act. But the Midwestern Machinery court also indicated that “continuing
violations restart the statute of limitations when there is an ongoing scheme, such as a price-fixing conspiracy or an
attempt to monopolize.” 392 F.3d at 275. As this quote reveals, the Midwestern Machinery court believed that the
continuing violations doctrine could be employed for claims of conspiracy or for maintaining a monopoly, but at no
point did it expressly indicate that the continuing violations should be applicable to Sherman merger or acquisition
claims. Id. This would have undercut the very logic that upheld the opinion.
No. 13-1254           Z Tech. Corp. v. Lubrizol Corp.                           Page 12

       Finally, Z Technologies argues that “[h]ad Lubrizol not raised prices and drawn the
attention of the Federal Trade Commission, it could have waited until the passing of the four
year statute and raised prices without consequences, but for an exception to the limitations
period.” Perhaps so. But this is not what occurred. Z Technologies was repeatedly harmed
within the limitations period, and it chose not to bring suit. This is precisely the type of conduct
that the statute of limitations is designed to prevent—parties sleeping on their rights. Moreover,
because we want to encourage plaintiffs not to sit on their rights, the statute of limitations is not
extended under the continuing violations doctrine if the plaintiff had actual knowledge of the
initial violation and suffered an injury. See Antitrust Law, ¶ 320c1 at 282, 289 (“Repose is
especially valuable in antitrust, where tests of legality are often rather vague, where many
business practices can be simultaneously efficient and beneficial to consumers but also
challengeable as antitrust violations.”); see also Kyle Graham, The Continuing Violations
Doctrine, 43 GONZ. L. REV. 271, 313–15 (2008). This general rule is particularly apt with
respect to private antitrust suits that are “allowed to correct public wrongs.” Midwestern,
392 F.3d at 272. By encouraging parties to bring suits earlier, the statute of limitations attempts
to minimize the public harm that might arise from harmful monopolies, while promoting mergers
by preserving repose for merged entities.

       Thus, Sixth Circuit precedent indicates price increases should not be treated as overt acts.
Because this position is consistent with others circuits and leading commentators, we conclude
that the price increases in the present case were not overt acts that extended the statute of
limitations.

           C. The Alleged Implementation of the Non-Compete Clause Is Not an Overt Act

       Z Technologies next argues that Lubrizol “prevent[ed] the Flint [P]lant from being re-
leased” and that this conduct constitutes an overt act for purposes of the continuing violations
doctrine. There is little proof to support this claim, apart from the mere existence of the non-
compete provision and a reference in the FTC complaint that “Lubrizol subsequently indicated
that this provision barred Lockhart from leasing its plant in Flint, Michigan, to another oxidates
manufacturer.” As Z Technologies admits, “Exactly what happened with the interpretation of
No. 13-1254            Z Tech. Corp. v. Lubrizol Corp.                          Page 13

this purchase agreement is not clear in the absence of discovery.” Nonetheless, Z Technologies
hypothesizes that “Lubrizol needed to take some action after its purchase to effect this outcome.”

       Unfortunately for Z Technologies, it has not raised its factual allegations above a
“speculative level.” Bell Atl., 550 U.S. at 555. Z Technologies would have us assume not only
that Lubrizol undertook an unknown action at an unknown time blocking the re-lease of the Flint
Plant, but also that this conduct was illegal and took place within four years and forty days of the
filing of the present suit. As the Supreme Court cautioned in Bell Atlantic, a “conclusory
allegation of [wrongful conduct] at some unidentified point does not supply facts adequate to
show illegality.” Id. at 556. Thus, as the well-pleaded facts “do not permit the court to infer
more than the mere possibility of misconduct, the complaint has alleged—but it has not shown—
that the pleader is entitled to relief.” Iqbal, 556 U.S. at 670 (internal citation and quotation
marks omitted).

       Even were this not the case, the implementation of the non-compete clause, which was
originally entered into at the time of the merger, does not constitute a “new and independent” act.
Under a contrary ruling, any contractual provision that was subsequently enforced would
arguably restart the statute of limitations, raising the risks associated with mergers and thereby
discouraging companies from merging. As discussed above, reaffirmations of a previously
announced policy, such as an acquisition or merger, are not considered overt acts, and therefore,
the continuing violations doctrine does not apply. For these reasons, the enforcement of a non-
compete clause is not an overt act extending the statute of limitations under the continuing
violations doctrine.

       As the continuing violations doctrine does not apply in the present case, we AFFIRM the
district court’s dismissal of the Sherman Act claim on statute of limitations grounds.

   3. Clayton Act Claim

       Z Technologies also alleges a hold-and-use violation under the Clayton Act. See United
States v. ITT Continental Baking Co., 420 U.S. 223, 240 (1975) (indicating that the Clayton Act
regulates “holding as well as obtaining assets”). The Clayton Act is an incipiency statute
designed to arrest and prohibit mergers and acquisitions that “lessen competition” or “tend to
No. 13-1254           Z Tech. Corp. v. Lubrizol Corp.                           Page 14

create monopoly.” 15 U.S.C. § 18; see United States v. E.I. du Pont de Nemours & Co.,
353 U.S. 586, 589 (1957). As with the Sherman Act, a Section 7 cause of action challenging an
acquisition accrues at the time of the merger or acquisition, and there is a four-year statute of
limitations. 15 U.S.C. § 15b; Concord, 207 F.3d at 1050. Similar to a continuing violation
under the Sherman Act, “different uses of assets can justify restarting the statute of limitations”
for a Clayton Act violation. Midwestern, 392 F.3d at 272, 275. If the assets are held and used in
the same manner as when they were acquired, the continued use is treated as an “unabated
inertial consequence of the merger.” Id. at 272. But “[i]f assets are used in a different manner
from the way that they were used when the initial acquisition occurred, and that new use injures
the plaintiff, he or she has four years from the time that the injury occurs to sue.” Id. at 273.
This analysis is referred to as the “hold-and-use” doctrine.

       Z Technologies makes two hold-and-use claims: (1) that Lubrizol caused the non-
competition clause “to be interpreted to prevent the re-leasing of the Flint oxidates plant;” and
(2) that Lubrizol “prevented the Flint [P]lant from being re-leased to prospective oxidates
manufacturers.”    Essentially, Z Technologies argues that the purported use of the non-
competition clause constituted a new use of an “asset” that extends the statute of limitations.

       This claim is also highly speculative in nature and does not satisfy the pleading standards
established under Twombly and Iqbal. Twombly, 550 U.S. at 556. But even if Z Technologies had
provided more detailed facts, the complaint still fails to supply a basis for the conclusion that
Lubrizol used the non-compete clause in a new or different manner. Midwestern, 392 F.3d at
272. The non-compete prohibited certain conduct at the time of signing and likewise prohibited
the same conduct a few years later. If the enforcement of a contractual provision, which was
included in the acquisition agreement presumptively to ensure certain conduct or to protect
certain rights, constitutes a “new” use of that provision, this will effectively undermine merger-
acquisition agreements and subject them to continual challenge.

       Tellingly, Z Technologies has not cited to a single case where implementation of a
contractual provision was found to violate the Clayton Act, and the cases actually cited illustrate
a far more circumscribed notion of what constitutes a “new and independent” act. For example,
in Free FreeHand Corporation v. Adobe Systems Inc., the district court found that ceasing
No. 13-1254           Z Tech. Corp. v. Lubrizol Corp.                           Page 15

development of software, channeling existing customers to a different software, and bundling
software constituted new post-merger acts. 852 F. Supp. 2d 1171, 1187 (N.D. Cal. 2012). But
as the district court emphasized, there was no indication that any of this conduct stemmed from
the merger or was included in the agreement creating the merger. Id. (“Just as in Smith v. eBay,
where plaintiffs’ monopolization claim was not based ‘solely on the fact that eBay acquired
Paypal,’ here, Plaintiffs’ claims are not based solely on the fact that Adobe acquired
Macromedia.” (internal citation omitted)). The same cannot be said here when the subsequent
action allegedly undertaken was a direct result of a term from the acquisition agreement. See
also Midwestern, 392 F.3d at 276 (rejecting the hold-and-use argument after determining that
market power acquired by the defendant as a consequence of the merger was not an “asset” and
had not been used differently); Concord, 207 F.3d at 1051 (rejecting the hold-and-use argument
because no evidence was shown of a different use and because the acquisition was public
knowledge).

       As the assets have not been used in a “new” fashion, we AFFIRM the district court’s
grant of summary judgment on statute of limitations grounds for the Clayton Act claim.

   4. Michigan Antitrust Claims

       The statute of limitations on the Michigan antitrust claims is also four years and forty
days, see Mich Comp. Laws § 445.781, and Michigan has expressly indicated that “in construing
all sections of this act, the courts shall give due deference to interpretations given by the federal
courts to comparable antitrust statutes,” Mich. Comp. Laws § 445.784(2).                   Thus, Z
Technologies’s state law claims rise and fall with its federal antitrust claims. See Little Caesar
Enters. v. Smith, 895 F. Supp. 884, 898 (E.D. Mich. 1995) (“Michigan antitrust law is identical
to federal law and follows the federal precedents.”). As the district court correctly determined
that the Sherman and Clayton Act claims are barred by the statute of limitations, we also
AFFIRM the dismissal of the Michigan antitrust claims.

                                       III. CONCLUSION

       For the foregoing reasons, we AFFIRM the district court’s grant of the motion to dismiss.
