MEMORANDUM OPINION & ORDER
Mоlecular Diagnostics Laboratories (“MDL”) brings this action against Hoff-mann-La Roche, Inc., Roche Molecular Systems, Inc. (collectively, “Roche”), PE Corporation, PE Biosystems Group, the Perkin-Elmer Corporation, PE Applied Biosystems, and Applera Corporation (collectively, “Applera”), on behalf of itself and a class of all those similarly situated, alleging that Roche and Applera violated the Sherman Act, 15 U.S.C. §§ 1 et seq. MDL claims that it was forced to pay an artificially inflated price for Thermus aquaticus DNA polymerase {“Taq") as a result of the enforcement by Applera and Roche of a patent allegedly obtained by fraud. Currently before the court are Roche’s and Applera’s motions to dismiss MDL’s complaint. Upоn consideration of the motions, the opposition thereto, and the record of this case, the court concludes that the motions must be denied.
I. BACKGROUND
Taq is a thermostable enzyme derived from Thermus aquaticus bacteria and an important component of a process known as “polymerase chain reaction” (“PCR”). PCR is a technique used to replicate DNA, allowing small DNA samples to yield larger quantities that can then be studied or manipulated. During the PCR process, a sample of DNA is subjected to rapid fluctuations between extreme temperatures— Taq is able to withstand these volatile temperature changes and still remain an effective catalyst for the replication of DNA.
Thermus aquaticus was discovered in the 1960s and, because it is able to survive in high temрerature environments, its potential application in the PCR process was quickly recognized. Cetus Corporation (“Cetus”) was among the scientific teams that attempted to isolate a thermostable polymerase from Thermus aquaticus. As early as 1985, Cetus and the Perkin-Elmer Corporation 1 entered into a joint venture called PE Cl, created “to commercialize Cetus’s DNA amplification technology.” Compl. ¶ 21. After a number of unsuccessful patent applications, on December 26, 1989, the United States Patent & Trademark Office (“PTO”) issued Cetus U.S. Patent No. 4,889,818 (“ ’818 patent”) for the DNA polymerase contained in Thermus aquaticus.
In 1991 Cetus assigned the ’818 patent to Roche as part of a transaction valued at approximately $300 million. 2 Compl. ¶ 17. Roche also purchased Cetus’s ownership interest in PECI, thereby assuming Cetus’s position in the partnership. Compl. *279 ¶ 22. In addition, various members of the Applera and Roche defendants subsequently entered into a distribution agreement used to facilitate the production, sale, and distribution of Taq.
Both Roche and Applera currently remain active in the Tag-market.
MDL, a direct purchaser of Tag, alleges that the market dominance enjoyed by Roche and Applera results from a fraudulently obtained patent. According to MDL, the application for the ’818 patent “materially misrepresented[ed] facts, om-itt[ed] specific and important contrary data, misstated] scientific principles, mis-present[ed] the content of prior art, аnd falsely reported] data.” Compl. ¶ 29.
On September 23, 2004 MDL filed the instant action. MDL claims that Applera and Roche, through the enforcement of the ’818 patent and “a variety of schemes and agreements,” 3 have conspired to monopolize the market for Taq, and restrained trade to the detriment of competitors and consumers. As a result of Applera’s and Roche’s allegedly anticom-petitive behavior, MDL asserts that it has suffered antitrust injury by being forced to pay “supra-competitive prices for Tag and PCR-related products.” Compl. ¶ 61.
II. DISCUSSION
Applera and Roche each move to dismiss the complaint pursuant to Fed.R.Civ.P. 12(b)(6) and 9(b) on a variety of grounds. The court will address their arguments in turn.
A. Standing
A grant of a patent exempts the holder from the normal prohibition against monopolies.
See Walker Process Equip., Inc. v. Food Mach. & Chem. Corp.,
In Walker Process, the Supreme Court permitted plaintiffs to seek treble damages under the antitrust laws when the fraudulent procurement of a patent is coupled with a violation of section 2 of the Sherman Act. Id. at 178. Here, MDL maintains that Applera and Roche used the ’818 patent, procured by fraud, to monopolize the market for Taq. Because MDL is a direct consumer of Tag, MDL assеrts that it has standing to prosecute a Walker Process claim as an injured party under the antitrust laws. In response, both Applera and Roche argue that the Walker Process decision did not contemplate direct consumers as suitable plaintiffs in this type of action. Rather, they contend, the only entity with standing to bring a Walker Process claim is a competitor or, more specifically, an entity against whom a fraudulently obtained patent is, or could be, enforced. 4
*280
Applera and Roche rely on
In re Remer-on Antitrust Litig.,
Carrot Components
is factually distinguishable. Unlike here, the plaintiff in
Carrot Components
was not a customer of the defendant, but rather claimed to be a competitor. The court dismissed thе complaint because the plaintiff “failed to establish that defendant had sought to enforce the patent against plaintiff, or that plaintiff had some reasonable basis for fearing such attempted enforcement.”
The court in In re Remeron, by comparison, did find that a direct purchaser lacked standing to bring a Walker Process claim. However, the court offered little justification for its holding, stating:
Plaintiffs, as direct purchasers, neither produced mirtzapine nor would have done so; moreover, Plaintiffs were not party to the initial patent infringement suits. Plaintiffs may not now claim standing to bring a Walker Process claim by donning the cloak of a Clayton Act monopolization claim.
The inclusion of the fact that the plaintiffs were not parties in the initial patent infringement suits suggests that the court confused the harm addressed through a
Walker Process
claim. The court appears to believe that, standing alone, the enforcement of the fraudulently procured patent is the relevant injury in a
Walker Process
claim, hence the court’s assertion that a plaintiff must be an actual or potential competitor. This, however, is not the case.
Walker Process
claims are intended to address antitrust injury, thus the requirement that a plaintiff be able to allege a violation of Section 2 of the Sherman Act.
5
See Walker Process,
*281
Viewed properly as an antitrust claim, there is little reason to think that standing requirements for
Walker Process
claims differ from standing requirements in more conventional antitrust actions.
See Unit-herm Food Sys., Inc. v. Swift-Eckrich, Inc.,
The court appreciates that a number of factors should be considered before adopting a broad rule with respect to standing. Conferring standing upon every individual tangentially affected by an alleged antitrust violation presents the risk of duplicative recovery, and may subject defendants to an onslaught of litigation.
See Hawaii v. Standard Oil Co.,
Examining these factors, the court sees no reason to limit standing to competitors. While entities facing enforcement actions are more likely to rely on Walker Process, this reflects more that they are in a stronger position to detect wrongdoing than a Congressional preference. If one believes that one of the primary purposes of a treble damages action is deterrence, then increasing the number of parties scrutinizing the actions of potential monopolists will further that goal. Moreover, because direct purchasers have frequent interactions with the defendants, they have a strong incentive to discover and litigate the offense. See William H. Page, The *282 Scope of Liability For Antitrust Violations, 37 Stan. L. Rev. 1445, 1488 (1985). Those against whom a patent is enforced, by comparison, will generally have limited contact with a defendant unless there is the suspicion of infringement.
Nor is there any particular difficulty in determining damages for direct purchasers.
As
the Supreme Court stated in
Illinois Brick,
direct purchasers are a preferred plaintiff, in part, for the ease of apportioning damages: “We conclude that the legislative purpose in creating a group of ‘private attorneys general’ to enforce the antitrust laws under § 4 is better served by holding direct purchasers to be injured to the full extent of the overcharge paid by them than by attempting to apportion the overcharge among all that may have absorbed a part of it.”
Based on the foregoing, analysis, the court finds that direct purchasers have standing to pursue Walker Process claims.
B. Statute of Limitations
Having decided that MDL has standing to assert the antitrust claims raised in its complaint, the court must next turn to Applera’s and Roche’s arguments that these claims are barred by the statute of limitations.
It is well settled that the statute of limitations for antitrust actions is four years.
See Klehr v. A.O. Smith Corp.,
Defendants urge that, at the latest, MDL was on notice of the alleged fraud perpetrated against the PTO by December 7, 1999. On this date, the court in
Hoffmann-La Roche, et al. v. Promega Corp.,
*283 MDL does not contest that it first became aware of its claims via the Promega litigation. However, MDL asserts that only a later, May 2004 decision — which reaffirmed the findings in the December 1999 opinion following a remand by the Court of Appeals for the Ninth Circuit— provided sufficient notice of its claims to initiate litigation. Compl. ¶ 52. According to MDL, Applera and Roche “fraudulently concealed” their anticompetitive conduct such that their deceptive conduct could not have been discovered earlier, and accordingly, the statute of limitations should be tolled until the actual discovery of the alleged wrongdoing.
The fraudulent concealment doctrine relieves a plaintiff from its obligation to comply with the relevant statute of limitations. Where the plaintiff:
remains in ignorance ... without any fault or want of diligence or care on his part, the bar of the statute does not begin to run until the fraud is discovered, though there be no special circumstances or efforts on the part of the party committing the fraud to conceal it from the knowledge of the other party.
Hobson v. Wilson,
Fraudulent concеalment, however, “does not come into play, whatever the lengths to which a defendant has gone to conceal the wrongs, if a plaintiff is on notice of a potential claim.”
Riddell v. Riddell Washington Corp.,
The requisite notice required to defeat a claim of fraudulent concealment is
*284
“an awareness of sufficient facts to identify ... the particular cause of action at issue, not [notice] of just any cause of action.”
Hobson,
By its own admission, MDL received notice of its claims following the publication of the May 2004 opinion in the Promega litigation. Compl. ¶ 52. The factual findings in the 2004 opinion, however, mirror those found in the court’s 1999 opinion. 9 The court sees no reason why the precise factual findings that MDL concedes provided notice of its claims in 2004, were insufficient to provide notice in 1999. MDL suggests that, because the 1999 decision was appealed, the court is incapable of deciding whether MDL was, “on an objec-five basis,” on reasonable notice of its claims. The court finds this argument unpersuasive. The law does not require that a claim be proven by a рreponderance of the evidence, and then affirmed on appeal, before a party is held to be on notice of a claim.
The notice that MDL received was specific and detailed. This is not an instance, such as in
In re Vitamins Antitrust Litig.,
Nor is this a case where MDL can argue that it was unaware of the litigation. Beyond Molecular’s reliance on the
Promega
litigation in its complaint, the court takes judicial notice that the
Promega
litigation, as well as the allegations of inequitable conduct, were well publicized.
See, e.g.,
Roche Ex. E (David Dickson,
Sparks Continue To Fly in
Taq
Patent Dispute,
Nature, Feb. 2, 1995, at 377 (“The principal issue at stake remains whether the thermostable enzyme extracted from
Taq
polymerase by scientists working for Cetus is identical to similar enzymes extracted from the same organism ... which had already been described several times in the literature.”)); Roche Ex. K,
(DNA-Analysis Patent Owned by Roche Unit is Found to Be Invalid,
Wall. St. J., Dec. 8, 1999, at B8 (“An important patent for DNA analysis owned by biotechnology giant Hoffman-La Roche was obtained by deliberately misleading the U.S. Patent and Trademark Office and is invalid, a federal judge ruled yesterday.”)). Moreover, because MDL is a participant in the same industry as the defendants, it is appropriate to impute knowledge of events that were widely circulated within the relevant scientific community.
See Jacobsen,
Accordingly, the court finds that the statute of limitations began to run on December 7, 1999 and expired on December 7, 2003, neаrly a year before MDL filed this action. As a result, in the absence of a continuous violation — addressed below— MDL’s complaint would be barred by the statute of limitations.
MDL insists that, even if it is prohibited from asserting claims arising from the allegedly fraudulent application for the ’818 patent in 1990, under a continuous violation theory it should still be permitted to seek redress for injuries that occurred during the four years preceding the filing of its complaint on September 23, 2004. MDL argues that each time Roche and Applera overcharged a customer, a new claim accrued.
Roche responds that the fraudulent procurement of a patent and subsequent enforcement of that patent is not a continuing violаtion. Rather, by analogizing to what it asserts is a similar case,
In re Relafen Antitrust Litig.,
The underlying logic of
In re Relafen,
however, supports a different conclusion. Though
In re Relafen
involved a class of drug purchasers suing a drug manufacturer for its enforcement of a patent allegedly procured by fraud, in holding that no continuing violation existed the court relied upon
Pace Indus., Inc. v. Three Phoenix Co.,
The instant case, however, does not involve a plaintiff competitor, nor is the enforcement of a patent the relevant injury. As discussed supra, MDL does not allege that Applera or Roche sought to enforce the ’818 patent against MDL. Instead, it *286 asserts that its injury arose through the payment of supra-competitive prices resulting from an illegitimately obtained monopoly on Taq.
That MDL is litigating this action as a purchaser, not a competitor, is a critical distinction. Indeed, the Second Circuit has clarified the implications of this difference in the plaintiffs market position vis a vis an argument that a continuing violation has occurred:
Although the business of a monopolist’s rival may be injured at the time the anticompetitive conduct occurs, a purchaser, by contrast, is not harmed until the monopolist actually exercises its illicit рower to extract an excessive price .... So long as a monopolist continues to use the power it has gained illicitly to overcharge its customers, it has no claim on the repose that a statute of limitations is intended to provide. Thus, in this setting, as in ‘the context of a continuing conspiracy to violate the antitrust laws ... each time a plaintiff is injured by an act of the defendants a cause of action accrues to him to recover the damages caused by that act .... As to those damages, the statute of limitations runs from the commission of the act.’
Berkey Photo Inc. v. Eastman Kodak Co.,
Having found that a direct purchaser has standing to assert a
Walker Process
claim, consistency requires a finding that the continuing violation theory entitles MDL tо pursue all claims accruing four years prior to the filing of its complaint. Because MDL is a purchaser, not a competitor, each time MDL was allegedly forced to pay a supra-competitive price as a result of Roche’s and Applera’s anticom-petitive conduct, a separate injury accrued.
See Klehr,
C. Conspiracy Allegations
Applera next asserts that MDL has failed to adequately plead the existence of a conspiracy between itself and Roche. According to Applera, MDL’s complaint fails to allege any conscious agreement to achieve an unlawful goal, and in addition, relies on only “legitimate business conduct” as evidence of any coordinated activity.
In considering Applera’s contentions, the court is mindful that a complaint may not be dismissed pursuant to Fed.R.Civ.P. 12(b)(6) “unless it appears beyond doubt that the plaintiff can prove no set of facts in support of his claim which would entitle him to relief.”
Conley v. Gibson,
With respect to Applera’s assertion that MDL’s complaint relies exclusively on “legitimate business conduct” as evidence of the alleged conspiracy, the court notes that “acts which are in and of themselves legal lose that character when they become constituent elements of an unlawful scheme.”
Cont'l Ore Co. v. Union Carbide & Carbon Corp.,
Because the court draws all reasonable inferences in MDL’s favor, it finds that MDL has met this threshold requirement. Reading the complaint as a whole, there are sufficient allegations that, by аgreement and through concerted activity, Appl-era and Roche sought to monopolize the market for Taq. Among the relevant statements in MDL’s complaint are the assertions that:
In the course of their PCR partnership, Roche and Applera have, through numerous agreements related to the development, licensing, and use of Taq and other PCR products, patent prosecution, and enforcement of the ’818 patent acted in concert and/or conspired with specific intent to dominate and monopolize the market for Taq. Compl. ¶ 63
Roche and Applera have entered into and engaged in a combination and conspiracy to suppress competition for Taq and to exploit jointly the market dominance facilitated by the fraudulently procured ’818 patent. Defendants also entered into numerous agreements involving joint decisions not to compete by price and otherwise, including market allocation agreements. Id. ¶ 67. 12
Taken together, these statements would permit a fact-finder to draw the reasonable *288 inference that Applera and Roche knowingly coordinated their activities in an effort to dominate the Taq market.
Applera would demand that MDL include more specific information with respect to these allegations. This is not what the law requires at this stage of the litigation, however. Accordingly, Appl-era’s motion to dismiss in regards to this issue is denied.
D. Lack of Particularity in Walker Process Claim
Finally, Apрlera moves to dismiss MDL’s complaint under Fed.R.Civ.P. 9(b) (“Rule 9(b)”). Applera contends that the complaint has failed to plead with particularity Applera’s knowledge of the fraud that underlies MDL’s Walker Process claim. That is to say, Applera asserts that MDL’s complaint provides insufficient detail as to whether or not Applera was aware of the alleged fraud involved in the procurement of the ’818 patent.
As an initial matter, the court questions whether Rule 9(b) is applicable to the requirement — present when the defendant enforcing a disputed patent is not the original patent applicant — that the party “en-forc[e] the patent with knowledge of the fraudulent manner in which it was obtained.”
Walker Process,
Assuming arguendo that an obligation to comply with Rule 9(b) exists when pleading a defendant’s knowledge of the underlying fraud in a Walker Process claim, MDL has met the requirement. 14 Rule 9(b) states that “in all averments of fraud or mistake, the circumstances constituting fraud or mistake shall be stated with particularly,” however, “malice, intent, knowledge, and other condition of mind of a person may be averred generally.” Fed.R.Civ.P. 9(b) (emphasis added). Accordingly, MDL’s assertions regarding Applera’s knowledge of the fraud before the PTO are sufficient. 15
Even if the court were to adopt a more stringent standard set forth by some courts — “that circumstances must be
*289
pleaded that provide a factual foundation for otherwise conelusory allegations of scienter,”
Stern v. Leucadia Nat’l Corp.,
As such, Applera’s motion to dismiss pursuant to Rule 9(b) is denied.
III. CONCLUSION
For the aforementioned reasons, it is this 1st day of December, 2005, hereby
ORDERED that Applera’s motion to dismiss [Dkt. # 9] and Roche’s motion to dismiss [Dkt. # 11] are DENIED.
Notes
. Applera Corporation is the successor in whole or part to defendants PE Biosystems Group, PE Applied Biosystems, PE Corporation, and/or the Perkin-Elmer Corporation.
. Roche holds other patents related to the PCR process, among them Patents Nos. 4,683,195 and 4,683,202. Compl. ¶ 18.
. MDL claims that defendants stifled competition by, among other things, enforcing the ’818 patent though affirmative litigatiоn. Specifically, MDL asserts that "Roche, acting on behalf of itself and on behalf of Applera’s predecessor PE, filed an action against Promega Corporation on October 27, 1992, in the United States District Court for the Northern District of California, alleging ... infringement of the '818 Patent” (“the Promega litigation”). Compl. ¶ 37.
. Defendants are indeed correct that the vast majority of
Walker Process
claims are brought by parties against whom a patent is enforced.
See Nobelpharma AB v. Implant Innovations, Inc.,
. Regardless of whethеr there is an antitrust violation, a party against whom a patent is being enforced is always free to raise, as a defense, that the patent was invalid as a result of "inequitable conduct.”
See Nobelpharma AB,
. The
In re Remeron
court's confusion is further evidenced by its acknowledgment that "[pjlaintiffs ... may bring antitrust claims on other grounds even though they are not direct
*281
competitors ....”
. Because the
Promega
litigation plays a central role in the court’s statute of limitations analysis, a brief history of the case is provided. Following Roche's purchase of the '818 patent, Roche came to believe that Promega was violating a license agreement negotiated with Cetus, and assigned to Roche following the purchase of the '818 patent.
See Hoffmann-La Roche Inc. v. Promega Corp.,
. The court notes that MDL argues that, even if the court were to find that Applera’s and Roche's alleged fraud was not self-concealing, defendants have also engaged in affirmative acts of concealment, among them initiating "sham litigation." Such "sham litigation” includes the patent enforcement action against Promega. Because the court finds that MDL was on notice of its claims prior to September 2000, it need not address this distinction.
. The 1999 Order in the
Promega
litigation made a number of specific factual findings in support of its holding that La Roсhe had engaged in inequitable conduct. Among the inequitable activities attributed to La Roche were: (1) "making misleading statements regarding the relative fidelity of
Taq
as compared to the prior art enzymes”; (2) "claiming that
Taq
purified by the method taught in Example VI had a specific activity of 250,000 units/mg”; (3) "presenting Example VI as though it had been performed when, in fact, it had not been performed”; (4) "making deceptive, scientifically unwarranted comparisons between the specific activity of the claimed enzyme and the specific activity reported by Chien et al. and Kalendin et al.”; (5) "claiming that
Taq
purified according to the method taught in Example VI yielded a single 88 ltd band on an SDS PAGE mini-gel”; and (6) "claiming that the
Taq
produced was free from nuclease contamination.”
. While MDL cites a number of cases in support of the proposition that whether a plaintiff was on notice should not be decided on a motion to dismiss, none of these cases involved the degree of notice present in the instant action. In
Firestone v. Firestone,
. For this reason, much of Applera’s cited authority is inapposite. Both
Northlake Mktg. & Supply, Inc. v. Glaverbel S.A.,
. In addition, the complaint alleges coordinated enforcement of the '818 patent.
Id.
¶ 37 ("[R]oche, acting on behalf of itself and on behalf of Applera’s predecessor PE, filed an action against Promega Corporation .-..”). The parties vigorously contest the significance of Applera’s involvement in the
Promega
litigation. It would be imprudent to decide this question of fact at this juncture, and instead, the court will accept MDL's assertion as pleaded. In addition, because MDL has pleaded that Applera had at least some involvement in the attempt to enforce the ’818 patent, the instant case is distinguishable from
Mitsubishi Electric Corp. v. IMS Tech., Inc.,
. There is no dispute that MDL has pled the alleged fraud before the PTO with sufficient particularity.
. The court observes that Rule 9(b) does not place a heavy burden on plaintiffs, given that Rule 9 must be read in conjunction with the relatively liberal pleading requirements of Rule 8.
See Shahmirzadi
v.
Smith Barney, Harris Upham & Co.,
. Allegations regarding Applera's knowledge of the alleged fraud involved in the procurement of the '818 patent appear throughout the complaint, for example:
"Applera and/or its predecessors have maintained agreements with Roche, and entered into new agreements with Roche, to preserve, extend, and exercise power over the Taq market, despite Applera's knowledge that the '818 patent was procured by fraudulent representations and omissions to the PTO. Compl. ¶ 34. (emphasis added);”
[D]efendants have threatened and filed legal actions asserting infringement of the '818 patent, despite being aware of the fraudulent conduct before the PTO that led to the procurement of the patent and, hence, the fact that the patent was invalid. Id. ¶ 37 (emphasis added).
