18 Presently before the Court is Defendant Eli Lilly and Company’s Motion for
19 Attorneys’ Fees Under 25 U.S.C. Section 285 (“Mot.,” ECF No. 80-1). Plaintiff
20 Genentech, Inc. filed a Response in Opposition to (“Opp’n,” ECF No. 82) and Defendant
21 filed a Reply in Support of (“Reply,” ECF No. 83) the Motion. The Court took the matter
22 under submission without oral argument pursuant to Civil Local Rule 7.1(d)(1). See ECF
23 No. 84. After considering the Parties’ arguments and the law, the Court DENIES
24 Defendant’s Motion.
25 BACKGROUND
26 Plaintiff Genentech, Inc. is the owner of U.S. Patent No. 10,011,654 (the “’654
27 patent”), entitled “Antibodies Directed to IL-17A/IL-17F Heterodimers.” First Amended
28 Complaint (“FAC”) ¶¶ 3, 18, ECF No. 29. The ’654 patent claims “methods of making
1 antibodies, including humanized antibodies, to the newly discovered IL-17A/F antigen.”
2 Opp’n at 2 (citing Ex. A, ECF No. 80-14 at 66:34-79:6, Example 1). Presently, Plaintiff
3 does not have a product covered by the ’654 patent. See Mot. at 7.
4 On July 2, 2018, simultaneous with the issuance of the ’654 patent, Plaintiff
5 commenced this action alleging Defendant Eli Lilly and Company infringed the ’654
6 patent. FAC ¶¶ 3, 5, 26–43. Defendant markets a formulation of an antibody called
7 ixekizumab as a treatment for moderate to severe plaque psoriasis and psoriatic arthritis in
8 adults under the trademark Taltz. Id. ¶ 3. Plaintiff alleged that the ixekizumab antibody
9 in Defendant’s Taltz falls within the scope of protection of the ’654 patent. Id. ¶ 26.
10 This action is part of a global dispute between Plaintiff and Defendant over the rights
11 to this discovery. The Parties have litigated numerous international actions over Plaintiff’s
12 European patents related to the ’654 patent, and foreign courts have examined the validity
13 of Plaintiff’s European patents. See, e.g., Eli Lilly & Co. v. Genentech, Inc, [2019] EWHC
14 387 (Pat), Ex. Y, ECF No. 80-38 (finding Plaintiff’s EP 1,641,822 B1, a European
15 counterpart related to the ’654 patent, invalid for obviousness); Eli Lilly & Co. v.
16 Genentech, Inc, [2020] EWHC 261 (Pat), Ex. Z, ECF No. 80-39 (finding Plaintiff estopped
17 from arguing EP 2,784,084 B1 claims are valid based on findings related to EP ’822
18 patent). The findings of the UK courts are on appeal. Opp’n at 17.
19 After Plaintiff filed the present action, Defendant filed a motion to dismiss the
20 original complaint and strike allegations therein. ECF No. 24. Before Plaintiff filed a
21 response, the Parties jointly moved for leave to file an amended complaint, ECF No. 27,
22 which the Court granted, ECF No. 28. Plaintiff then filed its FAC on October 17, 2018.
23 ECF No. 29. On November 13, 2018, Defendant filed a second motion to dismiss alleging
24 failure to state a claim and improper venue and moving to strike portions of Plaintiff’s
25 FAC. ECF No. 30. Shortly after Defendant filed the second motion to dismiss, Plaintiff
26 filed an ex parte application for leave to seek expedited discovery related to Defendant’s
27 contentions that venue was improper in this District. ECF No. 34. The Court granted the
28 motion and allowed limited discovery on the issue of venue. ECF No. 39. On September
1 12, 2019, the Court granted in part and denied in part Defendant’s motion to dismiss,
2 declining to strike portions of the FAC and finding venue was proper in this District, but
3 also finding that Plaintiff’s allegations as pleaded in the FAC were insufficient to support
4 a claim for willful infringement. ECF No. 59. On October 4, 2019, Defendant filed its
5 Answer and Affirmative Defense, pleading that the “asserted claims of the ’654 patent are
6 invalid under 35 U.S.C. § 112 for a lack of written description.” ECF No. 63 at 7.
7 On April 2, 2019, Defendant filed a petition for Post Grant Review (“PGR”) before
8 the Patent Trial and Appeal Board (“PTAB”), challenging the patentability of all claims of
9 the ’654 patent as unsupported by written description and enablement under 35 U.S.C.
10 § 112 and as anticipated under 35 U.S.C. § 102. See generally Ex. B, ECF No 80-15. On
11 October 7, 2019, the PTAB issued an Institution Decision finding that it is more likely than
12 not that the ’654 patent claims are unpatentable based on a lack of written description. See
13 Ex. E, ECF No. 80-18 at 11–12, 22–25.
14 On November 21, 2019, the Parties jointly moved to stay the instant case, ECF No.
15 69, and this Court granted the stay on November 26, 2019 pending a decision by the PTAB
16 regarding the patentability of patent ’654, ECF No. 72. Plaintiff requested four extensions
17 on the deadline to file its Patent Owner Response before the PTAB, and Plaintiff ultimately
18 never filed a response. Declaration of Katherine Helm (“Helm Decl.”) ¶ 10, ECF No. 80-
19 2. Plaintiff moved for an adverse judgement in the PTAB proceeding without ever making
20 substantive arguments in favor of patent ’654’s validity before this Court or before the
21 PTAB. Mot. at 1.
22 On February 26, 2020, Plaintiff moved for voluntary dismissal of this case with
23 prejudice. ECF No. 73. On March 16, 2020, this Court granted Plaintiff’s motion and
24 declared Defendant the prevailing party. ECF No. 77. On March 30, 2020, the Parties
25 filed a joint motion to bifurcate the “exceptional case” determination and attorneys’ fees
26 motion under Federal Rule of Civil Procedure 54(d)(2). ECF. No. 78. The Court granted
27 the joint motion, ECF No. 79, and Defendant subsequently filed the instant Motion seeking
28 a determination that this case is exceptional, ECF No. 80-1.
1 LEGAL STANDARD
2 Under 35 U.S.C. § 285, the court “in exceptional cases may award reasonable
3 attorneys’ fees to the prevailing party” in a patent infringement lawsuit. The Supreme
4 Court construed this language in Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572
5 U.S. 545, 553–54 (2014). Specifically, the Octane Court rejected the Federal Circuit’s pre-
6 Octane interpretation of the “exceptional case” language as “rigid and mechanical,”
7 holding that the prior method “impermissibly encumber[ed] the statutory grant of
8 discretion to district courts.” Id. at 553. Octane established a flexible approach: “[A]
9 district court may award fees in the rare case in which a party’s unreasonable conduct—
10 while not necessarily independently sanctionable—is nonetheless so ‘exceptional’ as to
11 justify an award of fees.” Id. at 555.
12 Under Octane, a case may warrant a fee award if the litigation is objectively baseless,
13 or if the litigation is brought in subjective bad faith. Id. In particular, a case is
14 “exceptional” when it “stands out from others with respect to the substantive strength of a
15 party’s litigating position (considering both the governing law and the facts of the case) or
16 the unreasonable manner in which the case was litigated.” Id. at 554. Courts may look to
17 pre-Octane case law for guidance on whether a case was litigated in an unreasonable
18 manner. SFA Sys., LLC v. Newegg Inc., 793 F.3d 1344, 1349 (Fed. Cir. 2015). District
19 courts “may determine whether a case is ‘exceptional’ in the case-by-case exercise of their
20 discretion, considering the totality of the circumstances.” Octane Fitness, LLC, 572 U.S.
21 at 554. To guide its discretion, a court may consider a non-exclusive list of factors,
22 including: “frivolousness, motivation, objective unreasonableness (both in the factual and
23 legal components of the case) and the need in particular circumstances to advance
24 considerations of compensation and deterrence.” Id. at n.6 (citing Fogerty v. Fantasy, Inc.,
25 510 U.S. 517, 534 n.19 (1994)). Additionally, Octane rejected the former requirement that
26 patent litigants establish their entitlements to attorneys’ fees by “clear and convincing
27 evidence” in favor of a lower, preponderance of the evidence standard. Id. at 557–58.
28 ///
1 Finally, Octane does not mandate attorneys’-fee awards in all exceptional cases; i.e.,
2 even if a court determines that a case is “exceptional,” the court still has discretion to deny
3 attorneys’ fees. See Ion Health & Fitness, Inc. v. Octane Fitness, LLC, Nos. 2011–1521,
4 2011–1636, 2014 WL 4194609, at *3 (Fed. Cir. 2014) (“The Supreme Court’s decision in
5 Octane did not, however, revoke the discretion of a district court to deny fee awards even
6 in exceptional cases.”); see also S.C. Johnson & Son, Inc. v. Carter-Wallace, Inc., 781 F.2d
7 198, 201 (Fed. Cir. 1986) (“Even an exceptional case does not require in all circumstances
8 the award of attorney fees.”).
9 ANALYSIS
10 The parties do not dispute that Defendant is a prevailing party as required by § 285.
11 Therefore, the award of attorneys’ fees turns on whether Defendant has carried its burden
12 to establish this case is exceptional.
13 Defendant raises several arguments why this case is exceptional. Defendant argues
14 that this case is exceptional because (1) Plaintiff’s case was objectively baseless because
15 the ’654 patent claims are facially invalid; and (2) Plaintiff acted with subjective bad faith
16 in initiating and persisting in these proceedings. See Mot. at 12–22. The Court discusses
17 Defendant’s arguments in turn, addressing Plaintiff’s counterarguments where relevant.
18 I. Substantive Strength of Litigation Position
19 Defendant argues that Plaintiff’s case was baseless because the ’654 patent claims
20 are facially invalid under controlling law. Mot. at 13–14. “To be objectively baseless, the
21 infringement allegations must be such that no reasonable litigant could reasonably expect
22 success on the merits.” Dominant Semiconductors Sdn. Bhd. v. OSRAM GmbH, 524 F.3d
23 1254, 1260 (Fed. Cir. 2008) (citation omitted). Defendant contends that functional genus
24 claims like those claimed in the ’654 patent “have been specifically repudiated by both the
25 Federal Circuit and corresponding PTO Guidance.” Mot. at 4. Specifically, the Federal
26 Circuit in Amgen Inc. v. Sanofi rejected the “newly characterized antigen test” as
27 “flout[ing] basic principles of the written description requirement.” 872 F.3d 1367, 1378
28 (Fed. Cir. 2017), cert. denied, 139 S. Ct. 787 (2019). Defendant argues that the patent
1 examiner applied the rejected newly characterized antigen standard to Plaintiff’s
2 application for the ’654 patent, and mistakenly issued the patent on this basis. Mot. at 4–
3 5.
4 Plaintiff argues that the ’654 patent was issued by the United States Patent and
5 Trademark Office (“USPTO” or “PTO”), and therefore it is presumed valid. Opp’n at 5.
6 Plaintiff states that Defendant “points to no authority finding the presumption of validity
7 is reduced by subsequent case law developments,” and it is Defendant’s burden to prove
8 invalidity. Id. at 6 (citing Microsoft Corp. v. i4i Ltd. P’ship, 564 U.S. 91, 95 (2011)).
9 The Federal Circuit decided Amgen on October 5, 2017, while prosecution of the
10 ’654 patent was still ongoing. In response to Amgen, the USPTO issued a Memorandum
11 on February 22, 2018 that instructed examiners not to allow claims based on the newly
12 characterized antigen test:
13 In view of the Amgen decision, adequate written description of a
newly characterized antigen alone should not be considered
14
adequate written description of a claimed antibody to that newly
15 characterized antigen, even when preparation of such an
antibody is routine and conventional.
16
17 . . .
18
The [earlier] training materials [utilizing the newly characterized
19 antigen test] are outdated and should not be relied upon as
reflecting the current state of the law regarding 35 U.S.C. §§ 101
20
and 112.
21
22 Ex. X. at 2–3, ECF No. 80-37 (emphasis in original).
23 It cannot be reasonably disputed that Plaintiff was aware of the Amgen decision
24 while prosecution of the ’654 patent was ongoing. In addition to Amgen being “widely
25 publicized and discussed in the patent law community,” Mot. at 6, Plaintiff’s Assistant
26 General Counsel sat on a panel on April 11, 2018, that described how “[t]he Federal
27 Circuit’s decision in Amgen Inc. v. Sanofi eliminated the ‘well-characterized antigen’ test
28 for compliance with the written description requirement for antibodies[,]” Ex. 7 at 10, ECF
1 No. 80-9. Moreover, Plaintiff argued in another action that a patent covering antibodies
2 lacked sufficient written description. See Baxalta Inc. v. Genentech, Inc., No. CV 17-509-
3 TBD, 2018 WL 3742610, at *7 (D. Del. Aug. 7, 2018).
4 Therefore, the question before the Court is whether the Amgen decision affected the
5 validity of the ’654 patent and placed Plaintiff in an exceptionally weak litigation position.
6 A. Presumption of Validity
7 Section 282(a) of the Patent Act provides that “[a] patent shall be presumed valid,”
8 and that “[t]he burden of establishing invalidity of a patent or any claim thereof shall rest
9 on the party asserting such invalidity.” 35 U.S.C. § 282(a). The party asserting invalidity
10 “has the added burden of overcoming the deference that is due to a qualified government
11 agency presumed to have properly done its job, which includes one or more examiners . . .
12 whose duty it is to issue only valid patents.” PowerOasis, Inc. v. T-Mobile USA, Inc., 522
13 F.3d 1299, 1304 (Fed. Cir. 2008) (quoting Am. Hoist & Derrick Co. v. Sowa & Sons, 725
14 F.2d 1350, 1359 (Fed. Cir. 1984)); see also Hyatt v. Kappos, 625 F.3d 1320, 1334 (Fed.
15 Cir. 2010) (en banc) (recognizing the deference owed to the USPTO as “the knowledgeable
16 agency charged with assessing patentability”). “The party supporting validity has no initial
17 burden to prove validity, having been given a procedural advantage requiring that he come
18 forward only after a prima-facie case of invalidity has been made.” Stratoflex, Inc. v.
19 Aeroquip Corp., 713 F.2d 1530, 1534 (Fed. Cir. 1983).
20 Defendant argues that Plaintiff “ignored controlling law and relied on what it knew
21 to be a rejected legal standard . . . as the basis to overcome written description rejections
22 by the PTO.” Mot. at 4. Therefore, Plaintiff “repeatedly evaded its duty to notify the
23 Examiner,” and as a result, the “Examiner mistakenly allowed the patent on this rejected
24 standard[.]” Id. at 4–5. Plaintiff counters that Defendant “has never alleged that the ’654
25 patent is unenforceable due to inequitable conduct . . . [and Defendant] cites no authority
26 that [Plaintiff] had a duty to disclose the Amgen decision during prosecution.” Opp’n at
27 16. Defendant argues that the Court need not determine whether Plaintiff’s actions during
28 patent prosecution amount to inequitable conduct to find that this case is exceptional. See
1 Reply at 5–6. While Defendant correctly states that the “exceptional case analysis . . .
2 considers whether a plaintiff’s conduct is unreasonable with respect to the factual and legal
3 components of the case,” id. at 6, Defendant argues that Plaintiff’s litigation was baseless
4 from its inception, see id. at 20. Given that Plaintiff initiated litigation immediately upon
5 issuance of the ’654 patent, it is reasonable for Plaintiff to rely on the ’654 patent’s
6 presumption of validity unless the patent was invalid. Therefore, the Court will examine
7 whether inequitable conduct invalidated the ’654 patent, which would render Plaintiff’s
8 initiating this action objectively unreasonable. Otherwise, the presumption of validity
9 provides Plaintiff with some basis for suing Defendant for patent infringement.
10 An otherwise valid patent may be rendered unenforceable by virtue of inequitable
11 conduct committed during the prosecution of the patent application before the USPTO.
12 Glaverbel Societe Anonyme v. Northlake Marketing & Supply, Inc., 45 F.3d 1550, 1556
13 (Fed. Cir. 1995). Patent applicants “have a duty to prosecute patent applications in the
14 [USPTO] with candor, good faith, and honesty.” Honeywell Int’l Inc. v. Universal Avionics
15 Sys. Corp., 488 F.3d 982, 999 (Fed. Cir. 2007). “A party asserting inequitable conduct
16 must prove by clear and convincing evidence that a patent applicant breached that duty by
17 (1) ‘fail[ing] to disclose material information or submit[ting] materially false information
18 to the PTO’ with (2) ‘intent to mislead or deceive the examiner.’” Advanced Magnetic
19 Closures, Inc. v. Rome Fastener Corp., 607 F.3d 817, 829 (Fed. Cir. 2010) (quoting
20 McKesson Info. Solutions, Inc. v. Bridge Med., Inc., 487 F.3d 897, 913 (Fed. Cir. 2007))
21 (alterations in original). The nondisclosure or misrepresentation must meet threshold
22 levels of both materiality and intent. Molins PLC v. Textron, Inc., 48 F.3d 1172, 1178
23 (Fed. Cir. 1995). Because a patent is presumed valid under 35 U.S.C. § 282, inequitable
24 conduct requires proof by clear and convincing evidence. Manville Sales Corp. v.
25 Paramount Sys., Inc., 917 F.2d 544, 551 (Fed. Cir. 1990).
26 Materiality is not limited to prior art, but instead embraces any information that a
27 reasonable examiner would be substantially likely to consider important in deciding
28 whether to allow an application to issue as a patent. GFI, Inc. v. Franklin Corp., 265 F.3d
1 1268, 1274 (Fed. Cir. 2001) (citing Akron Polymer Container Corp. v. Exxel Container,
2 Inc., 148 F.3d 1380, 1382 (Fed. Cir. 1998)). Pursuant to 37 C.F.R. § 1.56(b),
3 information is material to patentability when it is not cumulative
to information already of record or being made of record in the
4
application, and
5 (1) It establishes, by itself or in combination with other
information, a prima facie case of unpatentability of a
6
claim, or
7 (2) It refutes, or is inconsistent with, a position the
applicant takes in
8
(i) Opposing an argument of unpatentability relied on by
9 the Office, or
(ii) Asserting an argument of patentability . . .
10
11 Here, the patent examiner previously rejected claims of the ’654 patent for failure to
12 comply with the written description requirement. Ex. O at 6, ECF No. 80-28. In August
13 2016, Plaintiff argued the ’654 patent claims were supported by adequate written
14 description and overcame the examiner’s rejection by explicitly relying on the newly
15 characterized antigen test. Id. at 6–7 (citing Ex. W at Example 13, page 46, ECF No. 80-
16 36). Therefore, it appears the patent examiner would not have found the claims patentable
17 but for the application of the newly characterized antigen test. After the Amgen court
18 rejected the newly characterized antigen test in October 2017, it stands to reason that the
19 patent examiner should have reexamined these claims for their validity under the written
20 description standard articulated in Amgen. It is unclear from the evidence before the Court
21 whether the patent examiner did reevaluate the ’654 patent claims in light of Amgen.
22 Defendant argues Plaintiff failed to disclose the change in law to the patent
23 examiner, despite having numerous opportunities to do so before the patent was issued on
24 July 3, 2018. Mot. at 7–8. Plaintiff had interviews with the examiner on December 12,
25 2017 and January 2, 2018. Exs. Q, R, ECF Nos. 80-30, 80-31. Plaintiff had further contact
26 with the examiner after the USPTO issued the February Memorandum on Amgen, including
27 filing corrected application papers. See Exs. S, T, U, V, ECF Nos. 80-30–80-35.
28 ///
1 The patent examiner, whose “duty it is to issue only valid patents,” PowerOasis,
2 Inc., 522 F.3d at 1304, already should have been aware of Amgen during prosecution of
3 the ’654 patent because of the USPTO’s memorandum on the subject. Indeed, other courts
4 have found that it was reasonable for a patent applicant to assume that the examiner was
5 aware of important legal decisions issued while the patent was still undergoing prosecution,
6 and therefore “it was not unreasonable for [the plaintiff] to begin its litigation analysis with
7 the presumption of validity that initially attached to such patents.” CertusView Techs.,
8 LLC v. S & N Locating Servs., LLC, 287 F. Supp. 3d 580, 586 (E.D. Va. 2018); see also
9 DietGoal Innovations LLC v. Chipotle Mexican Grill, Inc., No. 2:12-CV-00764-WCB,
10 2015 WL 1284826, at *2 (E.D. Tex. Mar. 20, 2015) (finding that patent “issued well after
11 [relevant Supreme Court] decisions came down is prima facie evidence against” position
12 that patent was “obviously invalid”). Here, the patent was undergoing prosecution for eight
13 months after the Federal Circuit issued its decision in Amgen and four months after the
14 USPTO issued the memorandum advising examiners not to use the newly characterized
15 antigen test. This refutes Defendant’s assertion that the litigation was “baseless.” It was
16 not unreasonable for Plaintiff to assume its patent was valid because the examiner
17 presumably examined and issued the patent under Amgen.
18 Defendant has not met the threshold burden of showing materiality, and there is no
19 evidence before the Court that Plaintiff intended to deceive the examiner. In light of the
20 memorandum on Amgen issued by the USPTO, Plaintiff’s disclosure of the Amgen decision
21 would have been cumulative under 37 C.F.R. § 1.56(b). Therefore, Plaintiff was not
22 required to disclose the Amgen decision to the patent examiner because such a disclosure
23 would have been cumulative and therefore immaterial.
24 To overcome the presumption of validity, Defendant must prove by clear and
25 convincing evidence that Plaintiff committed inequitable conduct. Here, Defendant has
26 not carried its burden. Accordingly, the Court finds that Plaintiff could rely on the ’654
27 patent’s presumption of validity and there was a reasonable basis to bring this infringement
28 action.
1 When the newly characterized antigen test was rejected in Amgen, Plaintiff was on
2 notice that the ’654 patent claims were susceptible to attack under the written description
3 requirement. However, the Court finds Plaintiff’s position immediately after the issuance
4 of ’654 patent was not exceptionally weak because the ’654 patent was presumptively
5 valid. See CertusView Techs., LLC, 287 F. Supp. 3d at 587 (finding that infringement
6 claims were not “objectively unreasonable” where “there were no governing precedents to
7 guide [the plaintiff] that found nearly identical claims invalid”). It was not “clear that the
8 case should never have been brought from the outset.” Effective Expl., LLC v. BlueStone
9 Nat. Res. II, LLC, No. 216CV00607JRGRSP, 2018 WL 466246, at *2 (E.D. Tex. Jan. 18,
10 2018). Therefore, it was reasonable for Plaintiff to initiate the present action based on the
11 ’654 patent.
12 B. Developments After Patent Issuance
13 Having found that Plaintiff’s patent was not invalid for inequitable conduct, Plaintiff
14 “ha[d] the right to vigorously enforce its presumptively valid patent.” Homeland
15 Housewares LLC v. Sorensen Research & Dev. Trust, 581 Fed. Appx. 877, 881 (Fed. Cir.
16 2014). With this presumption in mind, Defendant next argues that Plaintiff persisting in
17 this litigation was objectively unreasonable because the ’654 patent was invalid under
18 Amgen. See Mot. at 13–14.
19 While Plaintiff is afforded a presumption of validity in the ’654 patent, Plaintiff
20 “must continually assess the soundness of pending infringement claims.” Taurus IP, LLC
21 v. DaimlerChrysler Corp., 726 F.3d 1306, 1328 (Fed. Cir. 2013). The statutory
22 presumption of validity does not relieve Plaintiff of its obligation under Federal Rule of
23 Civil Procedure 11 to certify that the claims set forth in its First Amended Complaint are
24 warranted by existing law. Indeed, “all plaintiffs have a duty to critically assess the merits
25 of their case prior to suit. . . . The issuance of a patent cannot and should not be a license
26 to sue with abandon.” Finnavations LLC v. Payoneer, Inc., No. 1:18-CV-00444-RGA,
27 2019 WL 1236358, at *2 (D. Del. Mar. 18, 2019) (granting attorneys’ fees because the
28 plaintiff asserted “clearly patent ineligible claims”).
1 Cases where subsequent changes in the legal landscape called into question the
2 validity of a patent are instructive here. In Inventor Holdings, the district court granted
3 attorneys’ fees based on the weakness of the plaintiff’s patent after the Supreme Court
4 decision in Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), and the need to
5 deter future “wasteful litigation.” Inventor Holdings, LLC v. Bed Bath & Beyond Inc., No.
6 CV 14-448-GMS, 2016 WL 3090633, at *3 (D. Del. May 31, 2016), aff’d, 876 F.3d 1372
7 (Fed. Cir. 2017). The Inventor Holdings district court held that “by the time of the Alice
8 decision, [the plaintiff] was on notice that its claims, much like the claims in Bilski [v.
9 Kappos, 561 U.S. 593 (2010),] and Alice, covered an abstract idea and that the introduction
10 of a computer into these claims did not alter the analysis,” meaning that the business
11 method claims were objectively ineligible under 35 U.S.C. § 101 by the time of Alice. Id.
12 at *4–5. The Federal Circuit concluded that the claims at issue were “manifestly directed
13 to an abstract idea” and agreed with the district court that the “asserted claims were plainly
14 invalid in view of Alice and its reasoning.” Inventor Holdings, LLC, 876 F.3d at 1378–79.
15 The Federal Circuit affirmed the district court’s award of attorneys’ fees and held that “[i]t
16 was [the plaintiff]’s responsibility to reassess its case in view of new controlling law.” Id.
17 Here, Plaintiff argues that the Amgen court did not establish a bright-line rule
18 invalidating all functional antibody genus claims, so Plaintiff was monitoring multiple
19 developments to assess the continuing soundness of its infringement claims. See Opp’n at
20 6–7, 13–14. First, Plaintiff claims that it was waiting for the outcome of the Amgen remand
21 trial and renewed motion for judgment as a matter of law. See id. at 13–14. The Amgen
22 remand trial concluded in February 2019, and the jury found Amgen’s patent claims, by
23 Plaintiff’s own admission “the claims most similar to the ’654 patent claims,” lacked
24 written description support and were invalid. Opp’n at 13; see Amgen Inc. v. Sanofi, No.
25 CV 14-1317-RGA, 2019 WL 4058927, at *1 (D. Del. Aug. 28, 2019), aff’d sub nom.
26 Amgen Inc. v. Sanofi, Aventisub LLC, 987 F.3d 1080 (Fed. Cir. 2021). Plaintiff contends
27 it also was waiting for the district court’s decision on Amgen’s renewed motion for
28 judgment as a matter of law as to the written description support for the broader claims.
1 Opp’n at 13–14. The district court dismissed the JMOL motion as moot on August 28,
2 2019. See generally Amgen, 2019 WL 4058927.
3 Second, Plaintiff claims it was “monitoring the Federal Circuit’s general trend
4 toward requiring a higher level of disclosure to satisfy the written description requirement.”
5 Opp’n at 14. Plaintiff cites to three cases that demonstrate this “general trend.” Opp’n at
6 14 (citing Idenix Pharm. LLC v. Gilead Scis. Inc., 941 F.3d 1149 (Fed. Cir. 2019); Purdue
7 Pharma L.P. v. Iancu, 767 F. App’x 918 (Fed. Cir. 2019); Quake v. Lo, 928 F.3d 1365
8 (Fed. Cir. 2019)). These cases invalidated patent claims based on lack of written
9 description support. Idenix Pharm. LLC, 941 F.3d at 1165–66; Purdue Pharma L.P., 767
10 F. App’x at 923–25; Quake, 928 F.3d at 1367, 1374. Defendant points out that these post-
11 Amgen cases are consistent with the law that existed at the time Plaintiff initiated the
12 present action. Reply at 2. Additionally, the decisions Plaintiff cites were issued months
13 before Plaintiff voluntarily dismissed this action. The Federal Circuit decided Purdue in
14 April 2019, Quake in July 2019, and Idenix in October 2019.
15 Finally, when the PTAB instituted the PGR, Plaintiff was faced with defending the
16 ’654 patent at a lower standard of proof than before a jury. Opp’n at 14–15. Although
17 Defendant would have needed to prove invalidity by clear and convincing evidence in this
18 Court, Defendant would only need to meet the preponderance of the evidence standard in
19 the PGR. Opp’n at 15 (citing 35 U.S.C. § 326(e); Microsoft Corp., 564 U.S. at 95).
20 Plaintiff claims this “changed the calculus considerably.” Id.
21 Plaintiff admits that these subsequent developments “cast considerable doubt over
22 whether [Plaintiff] would succeed in defending the validity of the ’654 patent claims.”
23 Opp’n at 14. By Plaintiff’s own admissions, Plaintiff was aware of its weakened litigating
24 position by August 2019 at the latest. This was almost six months before Plaintiff moved
25 to voluntarily dismiss this action. Plaintiff persisted litigating a case it had “considerable
26 doubt” over for months, during which time this Court decided Defendant’s second motion
27 to dismiss, Defendant filed an answer, the PTAB issued its institution decision, the parties
28 ///
1 moved to stay the present action, and Plaintiff requested four extensions to file its Patent
2 Owner Response before the PTAB.
3 This case is unusual because the significant change in the law that weakened
4 Plaintiff’s patent occurred during prosecution instead of after issuance. Therefore, the ’654
5 patent’s presumption of validity is in tension with Defendant’s assertion that the ’654
6 patent is clearly invalid for lack of written description. Ultimately, the Court has made
7 very little in the way of substantive findings in this case. See Munchkin, Inc. v. Luv n’
8 Care, Ltd., 960 F.3d 1373, 1375 (Fed. Cir. 2020) (reversing district court grant of attorneys’
9 fees where the merits of certain arguments were never fully adjudicated before the court).
10 The Court has not undertaken claim construction or examined the validity of Plaintiff’s
11 patent in light of Amgen. A significant body of law has developed around Alice, whereas
12 the same is not yet true for Amgen. The Amgen court held that “[a]n adequate written
13 description must contain enough information about the actual makeup of the claimed
14 products—‘a precise definition, such as by structure, formula, chemical name, physical
15 properties, or other properties, of species falling within the genus sufficient to distinguish
16 the genus from other materials,’ which may be present in ‘functional’ terminology ‘when
17 the art has established a correlation between structure and function.’” Amgen Inc., 872
18 F.3d at 1378 (quoting Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1350 (Fed. Cir.
19 2010)). Further, the Amgen court reminds us that “[a] determination that a patent is invalid
20 for failure to meet the written description requirement of 35 U.S.C. § 112, ¶ 1 is a question
21 of fact[.]” Id. at 1379 (quoting Ariad, 598 F.3d at 1355). The Court did not undertake this
22 fact-based inquiry on the ’654 patent, and it does not endeavor to do so here. While the
23 facts tend to indicate Plaintiff’s litigation position was weakened, the Court cannot go so
24 far as to find that the patent was facially invalid, as Defendant claims. Unlike the issuance
25 of Alice in Inventor Holdings, no single event after issuance “plainly invalid[ed]” the ’654
26 patent’s asserted claims. See Inventor Holdings, LLC, 876 F.3d at 1378–79. Therefore,
27 the Court does not attempt to draw lines as to when it became unreasonable to continue
28 ///
1 litigating the present action when Plaintiff’s case was founded on a presumptively valid
2 patent.
3 Additionally, Defendant is seeking an estimated $10 million in attorneys’ fees. Mot.
4 at 25. Plaintiff argues that Defendant “incurred such high costs for the PGR precisely
5 because the written description issues and the science in the case are complex.” Opp’n at
6 5. Defendant claims that, contrary to Plaintiff’s assertion, the expense of the PGR petition
7 “reflect[s] how important Taltz® is to [Defendant] and the patients it serves, and the high
8 stakes associated with a petition that . . . requires a single presentation of all of the
9 evidentiary and legal arguments up front.” Reply at 5 (citation omitted). The Court agrees
10 with Plaintiff. Although it is true that the PGR petition must be comprehensive, the length
11 and cost tend to show that this is not so straightforward a case as Defendant would have
12 this Court believe. It would be speculative for the Court to find Plaintiff’s patent clearly
13 invalid under Amgen when the Court has not undertaken the fact-intensive examination
14 necessary to support such a finding.
15 Although it appears that Plaintiff likely should have terminated this action sooner,
16 Plaintiff was not unreasonable in instituting the instant litigation because the ’654 patent is
17 afforded the presumption of validity. Although Plaintiff’s litigation position was weak
18 after Amgen, without more from Defendant, “[s]uch a superficial case cannot support a
19 finding of exceptionality.” Munchkin, Inc., 960 F.3d at 1380. Accordingly, this factor
20 weighs against an exceptional case finding.
21 II. Manner of Litigation
22 Turning to the second factor, the manner in which the case was litigated, Defendant
23 argues that Plaintiff acted in subjective bad faith in prosecuting the ’654 patent, initiating
24 this litigation, and then maintaining what Plaintiff knew was an “unwinnable” case. Reply
25 at 1.
26 The Federal Circuit has affirmed findings of litigation misconduct based on the
27 patentee’s destruction of relevant documents and lodging of incomplete and misleading
28 extrinsic evidence. Eon-Net LP v. Flagstar Bancorp, 653 F.3d 1314, 1324–25. (Fed. Cir.
1 2011). Other factors tending to show the case was litigated in an unreasonable manner
2 include “a pattern of litigation abuses characterized by the repeated filing of patent
3 infringement actions for the sole purpose of forcing settlements, with no intention of testing
4 the merits of one’s claims,” SFA Sys., LLC, 793 F.3d at 1350, and “an overall vexatious
5 litigation strategy and numerous instances of litigation misconduct,” Monolithic Power
6 Sys., Inc. v. O2 Micro Int’l Ltd., 726 F.3d 1359, 1366 (Fed. Cir. 2013).
7 First, Defendant argues that Plaintiff engaged in bad faith conduct in procuring the
8 ’654 patent. Mot. at 5. Defendant contends that Plaintiff “made no mention of the binding
9 legal precedent that eviscerated its patentability arguments to the Examiner.” Id. at 7. In
10 response, Plaintiff maintains that “[i]t properly obtained the ’654 patent in good faith.”
11 Opp’n at 19.
12 Although the Court found that Plaintiff was not required to disclose the Amgen
13 decision to the USPTO, see supra Section I.A., Plaintiff’s failure to do so was not in the
14 spirit of good faith patent prosecution. Amgen was a highly relevant legal development
15 that explicitly invalidated Plaintiff’s previous arguments. Although the Court presumes
16 that the patent examiner reexamined Plaintiff’s claims under Amgen based on the USPTO’s
17 memorandum, the ’654 patent’s prosecution history indicates that but for the application
18 of the newly characterized antigen test, the patent examiner would have found the claims
19 unpatentable for lack of written description. Therefore, a patent applicant acting in good
20 faith would have updated the examiner about a subsequent legal development that
21 invalidated its previous argument. Waiting to see if the patent examiner made the
22 connection between Amgen and Plaintiff’s previous position does not demonstrate candor
23 before the USPTO. See, e.g., Kingsland v. Dorsey, 338 U.S. 318, 319 (1949) (“[T]he
24 relationship of attorneys to the [USPTO] requires the highest degree of candor and good
25 faith.” (quotations omitted)). The Court does not condone Plaintiff’s behavior. Although
26 Plaintiff’s patent was presumptively valid, Plaintiff’s actions before the USPTO were
27 unreasonable.
28 ///
1 Second, Defendant argues that Plaintiff engaged in bad faith conduct by initiating
2 the ’654 patent dispute before this Court when it had notice from Defendant that the claims
3 of the ’654 patent would be held invalid under controlling law. Mot. at 14. Defendant
4 argues that the PTAB PGR institution decision confirmed that the claims of the ’654 patent
5 were more likely than not unpatentable under Amgen for lack of written description, but
6 Plaintiff continued to pursue this infringement action. Id. at 16–17. In response, Plaintiff
7 responds that its “litigation positions were not unreasonable, as evidenced by the
8 substantial effort required to mount an invalidity challenge at the PGR and the hard-fought
9 battle between the parties in the UK on related patents.” Opp’n at 19.
10 As an initial matter, the Court is not persuaded by Plaintiff’s argument that the “hard
11 fought battle between the parties in the UK on related patents” is evidence of good faith
12 litigation before this Court. Opp’n at 19. The ’654 patent is subject to different standards
13 of patentability than Plaintiff’s European patents. Therefore, while Plaintiff may have
14 stated a feasible claim in a foreign jurisdiction, Plaintiff still had a duty to litigate in good
15 faith before this Court. Part of Plaintiff’s duty includes ensuring that its claims are viable
16 under the law of this jurisdiction. See Taurus IP, LLC, 726 F.3d at 1328. However, the
17 Court has already determined that Plaintiff was entitled to a presumption of validity in the
18 ’654 patent because the patent was issued by the USPTO immediately before Plaintiff
19 initiated this litigation. See supra Section I.A. Therefore, Plaintiff did not have an
20 improper motive to bring this action. See Checkpoint Sys., Inc. v. All-Tag Sec. S.A., 858
21 F.3d 1371, 1375 (Fed. Cir. 2017) (“[M]otivation to implement the statutory patent right by
22 bringing suit based on a reasonable belief in infringement is not an improper motive.”).
23 As further evidence of Plaintiff’s bad faith, Defendant points to Plaintiff never
24 litigating any substantive aspect of the ’654 patent before this Court or the PTAB. Mot. at
25 15. Plaintiff did not offer a preliminary response to Defendant’s PGR petition on the
26 merits, and Plaintiff did not file a patent owner response or any substantive paper defending
27 the patentability of the ’654 patent claims. Id. at 17–18. Defendant argues that Plaintiff’s
28 “posturing and tactical maneuvering” was a tactic to hide that Plaintiff’s positions were
1 “unreasonable and untenable.” Id. at 18. Defendant claims Plaintiff’s avoidance of
2 litigating on the merits “was part of an unceasing worldwide strategy to extract a royalty”
3 from Defendant’s sales of Taltz. Id. at 1. Plaintiff argues that “[a]t the PGR institution
4 stage, the patent owner is not even required to file a preliminary response.” Opp’n at 8.
5 It does not appear that Plaintiff’s motivation in bringing this action was “to harass
6 or burden an opponent[.]” Checkpoint Sys., Inc., 858 F.3d at 1375. Those cases that courts
7 have found exceptional include “fil[ing] over fifty other lawsuits in the District Court to
8 exploit the high cost to defend complex litigation to extract nuisance value settlements
9 from various defendants.” Rothschild Connected Devices Innovations, LLC v. Guardian
10 Prot. Servs., Inc., 858 F.3d 1383, 1386 (Fed. Cir. 2017) (internal quotation marks and
11 citations omitted); see also Shipping & Transit, LLC v. Hall Enterprises, Inc., No. CV 16-
12 06535-AG-AFM, 2017 WL 3485782, at *7 (C.D. Cal. July 5, 2017) (granting attorneys’
13 fees where the plaintiff “repeatedly dismissed its own lawsuits to evade a ruling on the
14 merits and yet persists in filing new lawsuits advancing the same claims”). Although there
15 are multiple international actions between Plaintiff and Defendant, the Parties have
16 zealously litigated those foreign actions on the merits. In a 142-page judgment, the UK
17 judge stated the case concerning Plaintiff’s European counterpart to the ’654 patent was
18 “one of the most complex patent cases I have ever tried (and I have considerable experience
19 of trying complex patent cases).” Ex. Y at 639 (¶ 3). This observation does not imply a
20 series of nuisance cases, but instead suggests two juggernauts battling over the international
21 rights to this invention. It does not appear that Plaintiff has a pattern of filing baseless
22 lawsuits and then dismissing before litigating on the merits. While a pattern of repeatedly
23 dismissing could suggest Plaintiff was leveraging the high cost of litigation to extract a
24 royalty from Defendant, the Parties’ litigation history does not support this finding.
25 Although the Court does find it concerning that Plaintiff did not test the merits of its
26 infringement claims, it is not clear that it brought this action to harass Defendant.
27 Additionally, a substantive response from Plaintiff was not required until the Patent Owner
28 Response was due before the PTAB.
1 Next, Defendant points to contrary litigation positions Plaintiff took as early as May
2 2018—before the present action was filed—wherein Plaintiff argued that a patent’s
3 functional genus claims were invalid for lack of written description. Mot. at 16 n.6 (quoting
4 Brief for Defendant at 21-22, Baxalta Inc., 2018 WL 3742610, (May 15, 2018)). Plaintiff
5 concedes that Defendant “correctly notes [Plaintiff] was taking a defensive position on the
6 written description issue in other litigation.” Opp’n at 15 n.4 (citations omitted). Plaintiff
7 argues its “awareness of potential issue conflicts provides another good-faith reason for
8 [Plaintiff]’s decision to terminate this case.” Id.
9 Judicial estoppel “prevents a party from prevailing in one phase of a case on an
10 argument and then relying on a contradictory argument to prevail in another phase.”
11 Pegram v. Herdrich, 530 U.S. 211, 227 n.8 (2000). To find judicial estoppel, “a party’s
12 later position must be ‘clearly inconsistent’ with its earlier position.” New Hampshire v.
13 Maine, 532 U.S. 742, 750 (2001). In Baxalta, Plaintiff argued that “the patent lacks
14 sufficient written description to support the breadth of claim 1 under 35 U.S.C. § 112”
15 because the patent “fails to disclose a species representative of the structural breadth” and
16 “fails to disclose species representative in terms of diversity of functional effect.” 2018
17 WL 3742610, at *7–8. However, “[a] determination that a patent is invalid for failure to
18 meet the written description requirement of 35 U.S.C. § 112, ¶ 1 is a question of fact[.]”
19 Amgen Inc., 872 F.3d at 1379 (quoting Ariad, 598 F.3d at 1355). It is not clear that
20 Plaintiff’s position in this litigation would be “clearly inconsistent” with its arguments in
21 Baxalta, as the written description requirement is a fact-intensive inquiry specific to a
22 particular patent. Because the Court did not reach the merits of Plaintiff’s ’654 patent, it
23 is not clear how similar the ’654 patent is to the patent at issue in Baxalta. Therefore, the
24 Court does not find Plaintiff necessarily took contradictory positions in this litigation and
25 Baxalta.
26 Finally, Defendant argues that Plaintiff’s seeking of an adverse judgment against
27 itself in the PGR and the proceedings before this Court does not excuse Plaintiff’s bad faith
28 conduct. Id. at 19. Defendant contends Plaintiff seeking an adverse judgement was merely
1 result of Defendant “forcing [Plaintiff]’s hand” after Defendant incurred substantial
2 ||costs. Jd. Plaintiff pursued this action and participated in the PGR for twenty months
3 “before coming to an abrupt stop, without notice[.]” Jd. In response, Plaintiff contends it
4 ||“honored its duty to reassess its case and acted in good faith to withdraw from the
5 || proceedings and minimize litigation expenses for all involved.” Opp’n at 19.
6 The Court finds that staying the present action pending proceedings before the PTAB
7 || and moving to dismiss the case based on the findings of the PTAB was not, in light of the
8 ||record before this Court, unreasonable. See Pathway Innovations & Techs., Inc. v. IPEVO
9 || Inc., No. 17-CV-312-CAB-BLM, 2020 WL 1983485, at *2 (S.D. Cal. Apr. 24, 2020)
10 || (finding the plaintiff “agreeing to a stay while proceedings before the [United States
11 || International Trade Commission (“|ITC[”)] and PTAB were ongoing, and then dismissing
12 || the case based on the outcome of those proceedings—was not unreasonable”). Rather, the
13 || facts tend to indicate Plaintiff reevaluated its claims and rightfully moved to dismiss the
14 || case based on the PTAB’s institution decision, which the Court encourages when a party
15 || finds its litigation position is weakened.
16 While Plaintiff acted unreasonably in aspects of this litigation, most notably before
17 ||the USPTO during patent prosecution, the Court does not find these actions rise to an
18 || overall level of unreasonableness or bad faith such to warrant an exceptional case finding.
19 || Therefore, this factor weighs against an exceptional case finding.
20 CONCLUSION
21 Based on the foregoing, the Court concludes that under the totality of the
22 ||circumstances, Defendant has not shown that this case is exceptional such that an award of
23 |/attorneys’ fees is justified. The Court therefore DENIES Defendant’s Motion for
24 || Exceptional Case Finding and Attorneys’ Fees.
25 IT IS SO ORDERED.
