12 Plaintiff, ORDER GRANTING IN PART AND 13 v. DENYING IN PART DEFENDANT’S MOTION TO DISMISS 14 QUIDEL CORPORATION,

15 Defendant. (ECF No. 13) 16 17 Presently before the Court is Defendant Quidel Corporation’s Motion to Dismiss 18 (“MTD,” ECF No. 13). Also before the Court are Plaintiff FluorDx LLC’s Response in 19 Opposition to (“Opp’n,” ECF No. 14) and Defendant’s Reply in Support of (“Reply,” ECF 20 No. 15) the Motion. After considering Plaintiff’s Complaint, the Parties’ arguments, and 21 the law, the Court GRANTS IN PART and DENIES IN PART Defendant’s Motion. 22 BACKGROUND 23 Plaintiff FluorDx, LLC is a California limited liability corporation located in 24 Carlsbad, California. Compl. ¶ 3, ECF No. 1. Plaintiff is the owner by assignment of U.S. 25 Patent Number 9,274,056 (the “’056 Patent”), issued on March 1, 2016. Id. ¶ 5. The ’056 26 Patent describes an “assay method for detecting the presence of an analyte in a sample 27 using a test strip and then analyzing this strip in a reader that uses an LED light source as 28 the UV excitation source.” Id. ¶ 12. 1 Defendant Quidel Corporation is a Delaware corporation licensed to do business in 2 California and headquartered in San Diego, California. Id. ¶ 4. Defendant manufactures 3 and sells the Sofia and Sofia 2 immunoassay test systems. See id. ¶ 8. The Sofia system, 4 released in 2011, “use[s] lanthanide fluorochrome particles embedded in particles to test 5 for the presence of various analytes. This system or method uses a lateral flow test strip 6 with lanthanide fluorochrome particles to detect the desired analyte and the test strip is then 7 placed into the Sofia reader, which uses an LED light source to excite fluorescent emission 8 and quantify the result.” Id. The Sofia 2 system, released in 2018, is an upgrade to the 9 original Sofia system. Id. 10 Plaintiff filed its Complaint on October 17, 2019. See generally id. Plaintiff alleges 11 Defendant’s Sofia assay systems directly and indirectly infringe Claims 1, 2, 3, 4, 5, 6, 10, 12 11, 12, 14, 17, 18, and 20 of the ’056 patent. Id. ¶¶ 26–38. After being served with the 13 Complaint, Defendant filed the Motion now before the Court. See generally Mot. 14 LEGAL STANDARD 15 A 12(b)(6) motion to dismiss tests the legal sufficiency of the complaint. Fed. R. 16 Civ. P. 12(b)(6); Navarro v. Block, 250 F.3d 729, 732 (9th Cir. 2001). The pleading 17 standard requires only “a short and plain statement of the claim showing that the pleader is 18 entitled to relief.” Fed. R. Civ. P. 8(a)(2). To survive a motion to dismiss, however, the 19 claim to relief must be “plausible on its face.” Bell Atlantic Corp. v. Twombly, 550 U.S. 20 544, 570 (2007). Although a complaint need not contain “detailed factual allegations,” it 21 must provide more than “‘naked assertions’ devoid of ‘further factual enhancement.’” 22 Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (citing Twombly, 550 U.S. at 555–57). Mere 23 “labels and conclusions, and a formulaic recitation of the elements of a cause of action will 24 not do.” Twombly, 550 U.S. at 555. 25 When considering a 12(b)(6) motion, the court must accept all material allegations 26 of the complaint and “construe[ them] in the light most favorable to the nonmoving party.” 27 Cahill v. Liberty Mut. Ins. Co., 80 F.3d 336, 337–38 (9th Cir. 1996). The court need not 28 assume the truth of “legal conclusions” or “assume that ‘the [plaintiff] can prove facts that 1 [he or she] has not alleged.’” Naigan v. Nana Servs., LLC, No. 12-cv-2648 BAS (NLS), 2 2015 WL 300368, at *1 (S.D. Cal. Jan. 22, 2015) (alterations in original) (citing Assoc. 3 Gen. Contractors of Cal. v. Cal. State Council of Carpenters, 459 U.S. 519, 526 (1983)). 4 Dismissal may be based on the absence of a cognizable legal theory, or failure to allege 5 sufficient facts to support a cognizable legal theory. Balistreri v. Pacifica Police Dept., 6 901 F.2d 696, 699 (9th Cir. 1988). Upon dismissal, the district court should grant leave to 7 amend unless “the pleading could not possibly be cured by the allegation of other facts.” 8 Lopez v. Smith, 203 F.3d 1122, 1130 (9th Cir. 2000). When considering claims for 9 infringement of a patent, the pleading standards under Twombly and Iqbal govern. 10 Footbalance Sys. Inc. v. Zero Gravity Inside, Inc., No. 15-CV-1058 JLS (DHB), 2016 WL 11 5786936, at *2–3 (S.D. Cal. Oct. 4, 2016). 12 ANALYSIS 13 Defendant argues that Plaintiff has not plausibly alleged its claims for (1) direct 14 infringement, (2) indirect infringement, or (3) willful infringement. Mot. at 11–17. The 15 Court considers each argument in turn. 16 I. Direct Infringement 17 Plaintiff’s first claim against Defendant is for direct infringement under 35 U.S.C. 18 § 271(a), for “making, using, importing, offering to sell and selling in the United States the 19 Quidel Sofia and Sofia 2 assay systems.” Compl. ¶ 23. To state a claim for direct patent 20 infringement, a plaintiff must allege that the defendant, “without authority[,] makes, uses, 21 offers to sell, or sells any patented invention.” 35 U.S.C. § 271(a); see also Joy Techs., 22 Inc. v. Flakt, Inc., 6 F.3d 770, 773 (Fed. Cir. 1993) (citing Hewlett-Packard Co. v. Bausch 23 & Lomb Inc., 909 F.2d 1464, 1469 (Fed. Cir. 1990), cert. denied, 493 U.S. 1076 (1990)). 24 “To prove infringement, the patentee must show that an accused product embodies all 25 limitations of the claim either literally or by the doctrine of equivalents.” Cephalon, Inc. 26 v. Watson Pharms., Inc., 707 F.3d 1330, 1340 (Fed. Cir. 2013). “To establish literal 27 infringement, every limitation set forth in a claim must be found in the accused product, 28 exactly.” Advanced Steel Recovery, LLC v. X-Body Equip., Inc., 808 F.3d 1313, 1319 (Fed. 1 Cir. 2015) (citing Southwall Techs., Inc. v. Cardinal IG Co., 54 F.3d 1570, 1575 (Fed. Cir. 2 1995)). “Under the doctrine of equivalents, ‘a product or process that does not literally 3 infringe upon the express terms of a patent claim may nonetheless be found to infringe if 4 there is “equivalence” between the elements of the accused product or process and the 5 claimed elements of the patented invention.’” DePuy Spine, Inc. v. Medtronic Sofamor 6 Danek, Inc., 469 F.3d 1005, 1016 (Fed. Cir. 2006) (citing Warner–Jenkinson Co. v. Hilton 7 Davis Chem. Co., 520 U.S. 17, 21 (1997)). 8 Defendant contends Plaintiff fails to show that every limitation in Claim 1 of the 9 ’056 patent can be found in the accused products. Mot. at 11–13. The relevant portion of 10 independent Claim 1 of the ’056 patent claims: 11 1. An assay method for detecting the presence of an analyte in a sample, the method comprising: 12

13 a) providing a test strip comprising:

14 i) a label pad, said label pad comprising a plurality of particles 15 having a plurality of lanthanide fluorochrome molecules embedded therein, and a binding member or a hapten of the 16 analyte bound to the particle, said binding member capable of 17 binding to the analyte, wherein said lanthanide fluorochrome molecules are not chelated. 18 19 ’056 patent, 11:63–12:5. Defendant asserts that Plaintiff cannot show direct infringement 20 of every limitation because Claim 1 requires that the lanthanide fluorochrome molecules 21 are not chelated, id. at 7, while the lanthanide fluorochrome molecules in the Sofia systems 22 are chelated. Id. at 12. 23 Plaintiff responds, arguing that it pled a plausible claim of infringement supported 24 by sufficient facts. Opp’n at 15–16. Plaintiff contends that whether the lanthanide 25 fluorochrome molecules are chelated “is in reality an issue of claim construction.” Id. at 26 16. Plaintiff asserts that construing the term should be done only after the Court allows 27 briefing and holds a hearing, and that claim construction should not be decided on a motion 28 to dismiss. Id. at 17 (citing Fujitsu Ltd. v. Belkin Int’l, Inc., 782 F. Supp. 2d 868, 890 (N.D. 1 Cal. 2011) (“Claim construction and infringement analysis should not be resolved on a 2 motion to dismiss.”)). And even if the Court does entertain Defendant’s invitation to 3 conduct claim construction at this stage, Plaintiff contends that its construction is supported 4 by both the intrinsic and extrinsic record. Id. at 17, 19–21. Plaintiff contends that the 5 inventor acted as his own lexicographer, and that the term “not chelated” in Claim 1 means 6 only that the lanthanide fluorochrome molecules are not chelated to an antibody—it does 7 not mean the lanthanide fluorochrome molecules are not chelated at all. Id. at 17. 8 Although “claim construction at the pleading stage may be appropriate” in some 9 limited instances, it “may be inappropriate where . . . the Court finds that it would benefit 10 from additional briefing and evidence presented at the claim construction phrase.” Scripps 11 Research Inst. v. Illumina, Inc., No. 16-CV-661 JLS (BGS), 2017 WL 1361623, at *4 (S.D. 12 Cal. Apr. 14, 2017). Such is the case here. Plaintiff argues that the inventor acted as his 13 own lexicographer as to the term “not chelated.” Opp’n at 20. Plaintiff’s construction is 14 not clearly foreclosed at this stage, and the Court finds that it would benefit from additional 15 briefing and evidence presented. Claim construction at this stage is thus not warranted. 16 Defendant does not contend Plaintiff suffers any other pleading deficiencies as to 17 the claim for direct infringement, and the Court finds Plaintiff’s Complaint sufficiently 18 alleges the required elements. The Court therefore DENIES Defendant’s Motion to 19 Dismiss Plaintiff’s direct infringement claim. 20 II. Indirect Infringement 21 Plaintiff raises claims of indirect infringement for inducing infringement under 35 22 U.S.C. § 271(b), and contributory infringement under 35 U.S.C. § 271(c). 23 A. Inducing Infringement 24 Plaintiff’s alleges Defendant induced its customers to infringe the ’056 patent by 25 instructing them to use the Sofia assay systems in an infringing manner. Compl. ¶ 24. To 26 state a claim for inducement pursuant to 35 U.S.C. § 271(b), “the patentee must show, first 27 that there has been direct infringement, and second that the alleged infringer knowingly 28 induced infringement and possessed specific intent to encourage another’s infringement.” 1 Kyocera Wireless Corp. v. Int’l Trade Comm’n, 545 F.3d 1340, 1353–54 (Fed. Cir. 2008) 2 (quoting Minn. Mining & Mfg. Co. v. Chemque, Inc., 303 F.3d 1294, 1304–05 (Fed. Cir. 3 2002)) (internal quotation marks omitted). 4 Defendant asserts that “Plaintiff’s Complaint alleges no facts showing knowledge 5 and intent that the induced acts constitute patent infringement.” Mot. at 14. Defendant 6 contends that Plaintiff’s allegations regarding intent are insufficient because Plaintiff 7 alleges only that Defendant “provides instructions and teachings to use the Sofia products,” 8 which Defendant contends is insufficient to survive a motion to dismiss. Id. (citing Vita- 9 Mix Corp. v. Basic Holding, Inc., 581 F.3d 1317, 1328 (Fed. Cir. 2009)). 10 Plaintiff contends that its allegations of both knowledge and intent are sufficient. 11 Opp’n at 21–25. Regarding knowledge, Plaintiff points to allegations in the Complaint 12 that Defendant was advised of the ’056 patent application in 2009, Compl. ¶ 7; “was 13 advised of the ’056 patent and invited to review and discuss a license” in 2017, id. ¶ 9; and 14 responded that it was aware of the ’056 patent in 2018, id. ¶¶ 11, 24. As to intent, Plaintiff 15 alleges that Defendant “provided instructions to customers on the use of its products in a 16 manner that directly infringes the ’056 patent.” Opp’n at 24 (citing Compl. ¶¶ 14–19). 17 The Court finds Plaintiff’s allegations “sufficient to plead induced infringement.” 18 See DermaFocus LLC v. Ulthera, Inc., 201 F. Supp. 3d 465, 471 (D. Del. 2016). Drawing 19 all inferences in its favor, Plaintiff has plausibly pled that Defendant had knowledge of the 20 ’056 patent, and that Defendant induced its customers to infringe by providing instructions 21 to operate the Sofia systems using an infringing method. See id. (denying motion to dismiss 22 inducement claims where the defendant provided educational materials to customers); see 23 also In re Bill of Lading Transmission & Processing Sys. Patent Litig., 681 F.3d 1323, 24 1341 (Fed. Cir. 2012) (finding “it is more than reasonable to infer that [the defendant] 25 intended to induce its customers to use its products to practice the patented method” where 26 the defendant advertised its product could be used “to accomplish the[ advertised] benefits 27 through utilization of the patented method”). 28 /// 1 Defendant’s argument that these allegations are insufficient under Vita-Mix does not 2 change this conclusion. Although the court in Vita-Mix rejected the plaintiff’s arguments 3 that “the product instructions and the design of the device . . . support an inference of 4 intent,” the court rejected those arguments on a motion for summary judgment, finding the 5 “record devoid of actual evidence establishing specific intent to encourage customers to 6 infringe.” 581 F.3d at 1328. At the pleading stage, Plaintiff does not carry the burden to 7 show Defendant had the requisite intent based on evidence in the record; it need only show 8 its allegations are plausible. See In re Bill of Lading, 681 F.3d at 1331–32. Because 9 Plaintiff’s allegations of inducement are just that, the Court DENIES Defendant’s Motion 10 as to Plaintiff’s induced infringement claim. 11 B. Contributory Infringement 12 Plaintiff also alleges that Defendant contributed to infringing the ’056 patent through 13 its sales of the Sofia assay systems. Compl. ¶ 25. To establish contributory infringement 14 under 35 U.S.C. § 271(c), a plaintiff must show: “1) that there is direct infringement, 2) 15 that the accused infringer had knowledge of the patent, 3) that the component has no 16 substantial noninfringing uses, and 4) that the component is a material part of the 17 invention.” Fujitsu Ltd. v. Netgear Inc., 620 F.3d 1321, 1326 (Fed. Cir. 2010) (citing 35 18 U.S.C. § 271(c)). 19 Like the inducement claim, Plaintiff contends Defendant lacks sufficient factual 20 allegations to plausibly state a claim for contributory infringement. Mot. at 15–16. 21 Plaintiff argues that Defendant’s allegations “simply mirror the statutory language of 22 Section 271(c) and are insufficient.” Id. at 15. Defendant specifically argues that “Plaintiff 23 does not identify . . . which component(s) of Sofia are allegedly known to be especially 24 made or adapted for use in infringing the patent or how that component is not a stable 25 article of commerce suitable for noninfringing use.” Id. 26 Also like the inducement claim, the Court finds Plaintiff’s allegations sufficient to 27 plausibly state a claim. As noted above, Plaintiff has sufficiently alleged Defendant’s 28 direct infringement and knowledge of the ’056 patent. 1 As to whether the Sofia systems have noninfringing uses, Plaintiff alleges that 2 Defendant instructs end users to use the Sofia systems in a way that infringes on the ’056 3 patent, and that the systems must be used this way because they are “FDA registered[,] 4 meaning the . . . system must be used as directed by [Defendant] for use as a diagnostic 5 test.” Compl. ¶ 25. And regarding whether the Sofia systems are a material part of the 6 invention, Plaintiff contends the Sofia systems constitute a “material part of the patented 7 inventions” because they infringe the patent by “automatically perform[ing] the steps of 8 the claim methods of the ’056 patent.” Id. ¶ 23. Plaintiff plausibly alleges the Sofia 9 systems themselves are an “apparatus . . . for use in practicing a patented process.” 35 10 U.S.C. 271(c). Drawing all reasonable inferences in Plaintiff’s favor, the Court finds these 11 allegations sufficient. For these reasons, Defendant’s Motion to Dismiss Plaintiff’s 12 contributory infringement claim is DENIED. 13 III. Willful Infringement 14 Finally, Plaintiff alleges that Defendant willfully infringed the ’056 patent. Compl. 15 ¶ 39. Section 284 of Title 35 of the United States Code allows courts, in their discretion, 16 to “increase the damages up to three times the amount found or assessed” in cases of willful 17 or bad-faith infringement. 35 U.S.C. § 284. “[T]here is ‘no precise rule or formula’ for 18 awarding damages under section 284.” Halo, 136 S. Ct. at 1932 (quoting Octane Fitness, 19 LLC v. ICON Health & Fitness, Inc., 572 U.S. 545, 1756 (2014)). Instead, district courts 20 should narrow their discretion “so that such damages are generally reserved for egregious 21 cases of culpable behavior.” Id. 22 “[C]ulpability is generally measured against the knowledge of the actor at the time” 23 the infringement occurs. Id. at 1933. Thus, courts have held that “[k]nowledge of the 24 patent alleged to be willfully infringed” is a “prerequisite to enhanced damages.” WBIP, 25 LLC v. Kohler Co., 829 F.3d 1317, 1341 (Fed. Cir. 2016). “[A]llegations of knowledge 26 alone,” however, “are insufficient.” Cont’l Circuits LLC v. Intel Corp., No. CV16-2026 27 PHX DGC, 2017 WL 2651709, at *8 (D. Ariz. June 19, 2019) (citing Halo, 136 S. Ct. at 28 1936 (Breyer, J., concurring)). While “[s]ection 284 allows district courts to punish the 1 full range of culpable behavior,” Halo, 136 S. Ct. at 1933–34, the “sort of conduct 2 warranting enhanced damages” should be reserved for conduct “variously described . . . as 3 willful, wanton, malicious, bad-faith, deliberate, consciously wrongful, flagrant, or— 4 indeed—characteristic of a pirate.” Id. at 1932. Thus, to plead willful infringement, a 5 plaintiff must generally state facts that show (1) the defendant knew, or should have known, 6 of the patent; and (2) the defendant acted egregiously. 7 Although the Court finds Plaintiff’s Complaint contains sufficient allegations to 8 show knowledge, Plaintiff fails to show egregiousness. “Nothing in the [C]omplaint 9 provides specific factual allegations about [Defendant]’s subjective intent or details about 10 the nature of [Defendant]’s conduct to render a claim of willfulness plausible, and not 11 merely possible.” See Hypermedia Navigation LLC v. Google LLC, No. 18-CV-06137- 12 HSG, 2019 WL 1455336, at *4 (N.D. Cal. Apr. 2, 2019). Plaintiff’s only allegations of 13 willfulness are that Defendant “has been involved in license discussions about the ’056 14 patent, yet chose to not take a license,” and that Defendant “either knows or is choosing to 15 willfully blind itself to its infringement of the ’056 patent.” Compl. ¶ 39. Refusing a 16 license alone, however, does not show willfulness; indeed, Defendant’s refusal is “equally 17 consistent with a defendant who subjectively believes the plaintiff’s patent infringement 18 action has no merit.” Slot Speaker Techs., Inc. v. Apple, Inc., No. 13-CV-01161-HSG, 19 2017 WL 4354999, at *2 (N.D. Cal. Sept. 29, 2017). Without more, Plaintiff alleges only 20 “garden-variety” infringement that does not rise to the level of an “egregious case[] of 21 misconduct beyond typical infringement.” Halo, 136 S. Ct. at 1935. 22 The Court therefore GRANTS Defendant’s Motion to Dismiss Plaintiff’s willful 23 infringement claim. See Cont’l Circuits LLC, 2017 WL 679116, at *11 (dismissing willful 24 infringement claim where plaintiff “alleged sufficient facts to show knowledge, but not to 25 show the additional element of egregiousness”). 26 /// 27 /// 28 /// 1 CONCLUSION 2 For the reasons stated, the Court GRANTS IN PART and DENIES IN PART 3 ||Defendant’s Motion. Specifically, the Court DENIES Defendant’s Motion to Dismiss 4 Plaintiffs direct and indirect infringement claims, GRANTS Defendant’s Motion to 5 ||Dismiss Plaintiffs willful infringement claim, and DISMISSES WITHOUT 6 || PREJUDICE Plaintiff's willful infringement claim. Plaintiff MAY FILE an amended 7 complaint, if any, by August 18, 2020. If Plaintiff does not file an amended complaint by 8 date, Defendant SHALL FILE a response to the remaining claims in □□□□□□□□□□ 9 Complaint by September 1, 2020. 10 IT IS SO ORDERED. 11 ||Dated: August 4, 2020 tt 12 pee Janis L.
