Saris, D.J.

INTRODUCTION Plaintiff Ocean Semiconductor LLC (“Ocean”) alleges that Defendant Analog Devices, Inc. (“ADI”) infringes claims 4 and 5 of U.S. Patent No. 6,836,691 (“the ’691 patent”), a “Method and Apparatus for Filtering Metrology Data Based on Collection Purpose,” both directly and indirectly in violation of 35 U.S.C. §§ 271(a), (b), & (g) (Count III). ADI has moved to dismiss on the grounds that Ocean has (1) failed to plausibly allege that the newly accused system, Inficon’s FabGuard system, infringes the ’691 patent and has also (2) failed to plead scienter sufficient to satisfy claims under 35 U.S.C. §§ 271(b) & (g). For the following reasons, the Court DENIES IN PART and ALLOWS IN PART ADI’s motion to dismiss (Dkt. 143).

BACKGROUND On March 28, 2023, the Court allowed without prejudice ADI’s motion to dismiss under 35 U.S.C. § 101 (Dkt. 126). See Ocean Semiconductor LLC v. Analog Devices, Inc., No. 20-12310, 2023 WL 2662186 (D. Mass. Mar. 28, 2023). The Court assumes familiarity with that opinion. Ocean was granted leave to replead “if there [was] a factual basis for alleging that ADI infringed claims 4 and 5” of the ’691 patent. Id. at *8. In discussing these two claims,

the Court found the following: Claims 4 and 5 . . . describe identifying the presence or absence of a workpiece fault and changing the collection purpose data in response. . . . [They] are devoted to the abstract idea of “filtering” but are saved at step 2 [of Alice Corp. Pty. Ltd. v. CLS Bank Int'l, 573 U.S. 208 (2014)] because they carve out a specific innovation as to the use of fault detection data so that the “collection purpose data” is evaluated based on the presence or absence of evidence of faulty data. . . . . The Court cannot conclude that, as a matter of law, the specific technical improvement to the [semiconductor] manufacturing process in claims 4 and 5 is not inventive. The record, the complaint, the specification, and patent claims 4 and 5 together contain concrete allegations that a limitation of excluding false data was not routine or conventional.

Id. at *7-8. On April 27, 2023, Ocean filed a Second Amended Complaint (“SAC”) which alleges for the first time that ADI employs Inficon’s FabGuard system, which fabricates or manufactures products that infringe the ’691 patent. See Dkt. 134. On May 24, 2023, Ocean filed a Third Amended Complaint (“TAC”). See Dkt. 142. In its TAC, Ocean alleges that claims 4 and 5

“specifically provide for additional steps of identifying whether or not a fault condition is present based on the metrology data and changing the collection purpose data responsive to the presence or absence of a fault condition.” Dkt. 142 at 17. The TAC also alleges that use of the Inficon’s FabGuard system infringes the ’691 patent. Id. at 35. LEGAL STANDARD

To survive a Rule 12(b)(6) motion to dismiss, the factual allegations in a complaint must “possess enough heft” to state a claim to relief that is plausible on its face. Bell Atl. Corp. v. Twombly, 550 U.S. 544, 557 (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) (citing Twombly, 550 U.S. at 556). “Plausible, of course, means something more than merely possible, and gauging a pleaded situation’s plausibility is a context-specific job that compels [the court] to draw on [its] judicial experience and common sense.” Schatz v. Republican State Leadership Comm., 669 F.3d 50, 55 (1st Cir. 2012) (cleaned up) (quoting Iqbal, 556 U.S. at 679). DISCUSSION I. Plausibility of Infringement ADI argues that Ocean does not provide factual allegations

that support a plausible claim that the newly accused system, Inficon’s FabGuard system, infringes claims 4 and 5 of the ’691 patent, specifically “the critical claim step of ‘changing the collection purpose data.’” Dkt. 144 at 4. According to ADI, none of the allegations in the claim chart Ocean appended to the TAC support a plausible inference that the accused system meets the “changing the collection purpose data” element. Ocean disagrees, arguing that the claim chart demonstrates the plausibility of its claim and gives the alleged infringer fair notice. The Federal Circuit has ruled that a plaintiff is “not required to plead infringement on an element-by-element basis.” Bot M8 LLC v. Sony Corp. of Am., 4 F.4th 1342, 1352 (Fed. Cir.

2021). “[I]t is enough that a complaint place the alleged infringer on notice of what activity is being accused of infringement.” Id. (cleaned up) (quoting Lifetime Indus., Inc. v. Trim-Lok, Inc., 869 F.3d 1372, 1379 (Fed. Cir. 2017)). “The level of detail required in any given case will vary depending upon a number of factors, including the complexity of the technology, the materiality of any given element to practicing the asserted claim(s), and the nature of the allegedly infringing device.” Id. at 1353; see also Disc Disease Sols. Inc. v. VGH Sols., Inc., 888 F.3d 1256, 1260 (Fed. Cir. 2018) (finding that a plaintiff need not plead every element but must only give the alleged infringer fair notice). ADI argues that Ocean’s claim chart for the ’691 patent (which

is at least 100 pages long) fails to support a plausible inference that the accused system satisfies the “changing the collection purpose data” limitation. The term “collection purpose data” is referenced at least twenty times in Ocean’s claim chart. See Dkt. 142-3 (Exhibit F) at 26, 28, 30, 37-41, 44, 78-79, 81, 83, 86-87, 101, 103, 105, 107-08. Moreover, Ocean asserts at least nine allegations as to how the accused system meets the “changing the collection purpose data” claim element. See id. at 78-89, 101-09. For example, for claim 4, Ocean alleges that “through FabGuard’s root cause analysis, collection purpose data is changed responsive to the fault detection” and “FabGuard changes the collection purpose data in respons[e] to the fault detection.” Id.

at 86-87 (emphasis added). For claim 5, Ocean alleges that “the FabGuard system is able to change the collection purpose data.” Id. at 108 (emphasis added). Ocean also adds that: As an additional example, the FabGuard system is able to change the collection purpose data responsive to identifying the absence of the fault condition because it “can build mathematical correlations between real-time parameter behavior and post-process metrology results” and “[t]hese correlations can be used to improve the knowledge used to determine equipment health, as it takes into account process health beyond available real-time information[.]” Id. at 107 (first alteration in original).
