Before O’MALLEY, WALLACH, and TARANTO, Circuit Judges. Opinion for the court filed by Circuit Judge WALLACH. Dissenting opinion filed by Circuit Judge O’MALLEY. WALLACH, Circuit Judge. Appellant Uniloc 2017 LLC (“Uniloc”) appeals the U.S. Patent and Trademark Office’s (“USPTO”) Patent Trial and Appeal Board’s (“PTAB”) denial of its motion for re- hearing in the inter partes review (“IPR”) of Uniloc’s U.S. Patent No. 8,566,960 (“the ’960 patent”), arguing that “[t]he PTAB misapprehended the law in concluding it is permissible in an IPR proceeding for the [PTAB] to con- sider a § 101 challenge” to Uniloc’s proposed substitute claims (“the Substitute Claims”). J.A. 597; see J.A. 596– 602 (Uniloc’s Request for Rehearing). In denying Uniloc’s request, the PTAB concluded that it may analyze § 101 Case: 19-1686 Document: 87 Page: 3 Filed: 07/22/2020

The USPTO Director designated the Rehearing De- nial as precedential. See id. Uniloc timely appealed under 35 U.S.C. §§ 141(c), 142, and 319. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(A). We affirm. BACKGROUND I. The Statutory Framework Congress enacted the Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112–29, 125 Stat. 284, in 2011 to “improve patent quality and limit unnecessary and coun- terproductive litigation costs[,]” H.R. REP. No. 112-98, pt. I, at 40 (2011). The AIA included changes to the inter partes reexamination provisions. See 35 U.S.C. §§ 311–319 (to- gether, the “IPR Statutes”). Specifically, Congress re- placed inter partes reexamination with IPR, which “was designed to improve on the inter partes reexamination pro- cess.” Regents of the Univ. of Minn. v. LSI Corp., 926 F.3d 1327, 1335 (Fed. Cir. 2019), cert. denied, 140 S. Ct. 908 (2020). “Although Congress changed the name from ‘reexamination’ to ‘review,’ nothing convinces us that, in doing so, Congress wanted to change its basic purposes, namely to reexamine an earlier agency decision.” Id. (quot- ing Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2137 (2016)). Under the AIA, “a person who is not the owner of a pa- tent may file with the [USPTO] a petition to institute an [IPR] of the patent[,]” 35 U.S.C. § 311(a), but may “request to cancel as unpatentable [one] or more claims of a patent only on a ground that could be raised under [§] 102 or 103[,]” id. § 311(b); see id. §§ 102(a)(1) (2006) (providing that “[a] person shall be entitled to a patent unless the claimed invention was patented, described in a printed Case: 19-1686 Document: 87 Page: 4 Filed: 07/22/2020

publication, or in public use, on sale, or otherwise available to the public before [its] effective filing date”), 103 (2006) (“A patent may not be obtained . . . if the differences be- tween the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.”). 1 The USPTO Director may institute an IPR if the petition “shows that there is a reasonable likeli- hood that the petitioner would prevail with respect to at least [one] of the claims challenged in the petition.” Id. § 314(a); see Oil States Energy Servs. v. Greene’s Energy Grp., LLC, 138 S. Ct 1365, 1371 (2018) (“The decision whether to institute [IPR] is committed to the Director’s discretion.”). The PTAB “shall . . . conduct each [IPR] in- stituted[,]” 35 U.S.C. § 316(c), where “the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence[,]” id. § 316(e). “During an [IPR] . . . , the patent owner may file [one] motion to amend the patent” by “[c]ancel[ing] any chal- lenged patent claim” and “[f]or each challenged claim, pro- pose a reasonable number of substitute claims.” Id. § 316(d)(1). The proposed substitute claims “may not en- large the scope of the claims of the patent or introduce new matter.” Id. § 316(d)(3). When an IPR is completed, “the [PTAB] shall issue a final written decision with respect to

However, because the application that led to the ’960 patent never contained a claim having an effective fil- ing date on or after March 16, 2013 (the effective date of the statutory changes enacted in 2011), or a reference un- der 35 U.S.C. §§ 120, 121, or 365(c) to any patent or appli- cation that ever contained such a claim, the pre-AIA § 102 and § 103 apply. See id. § 3(n)(1), 125 Stat. at 293. Case: 19-1686 Document: 87 Page: 5 Filed: 07/22/2020

the patentability of any patent claim challenged by the pe- titioner and any new claim added under [§] 316(d).” Id. § 318(a). Moreover, “the Director shall issue and publish a certificate . . . incorporating in the patent by operation of the certificate any new or amended claim determined to be patentable.” Id. § 318(b). “Any proposed amended or new claim determined to be patentable and incorporated into a patent following an [IPR]” will “have the same effect as” reissued patents have on certain intervening rights under 35 U.S.C. § 252. Id. § 318(c). II. The ’960 Patent Entitled “System and Method for Adjustable Licensing of Digital Products,” the ’960 patent is directed to the “prob- lem . . . that consumers of software . . . use . . . digital prod- ucts on multiple devices[,]” where consumers have “a legitimate need to install and use the software on every computer.” ’960 patent col. 1 ll. 31–34, 40–41. The ’960 patent teaches the “adjust[ment] [of] the number of devices allowed to use a digital product (e.g., software) under a li- cense.” Id., Abstract. To enable the communication involv- ing the adjustable license, the ’960 patent discloses computer components, such as a “processor module” and a “memory module.” Id. col. 7 ll. 46–47; see id. col. 7 ll. 36– 47. Independent claim 26, proposed as a substitute to in- dependent claim 1, is illustrative of the Substitute Claims, and recites: A system for adjusting a license for a digital prod- uct over time, the license comprising at least one allowed copy count corresponding to a maximum number of devices authorized for use with the digi- tal product, comprising: a communication module for receiving a re- quest for authorization to use the digital Case: 19-1686 Document: 87 Page: 6 Filed: 07/22/2020

J.A. 339–40. 2 III. Procedural History Appellees Hulu, LLC and Netflix, Inc. (together, “Hulu”) filed a petition with the PTAB to institute an IPR of claims 1–25 of Uniloc’s ’960 patent. J.A. 89; see J.A. 89– 164 (Petition for IPR). 3 The PTAB instituted the IPR in August 2017. Amazon.com, Inc. v. Uniloc Lux. S.A. (“Insti- tution Decision”), No. IPR2017-00948, 2017 WL 3484959 (P.T.A.B. Aug. 14, 2017). On August 1, 2018, the PTAB issued a final written decision finding claims 1–8, 18–22, and 25 unpatentable over the prior art. See Amazon.com, Inc. v. Uniloc Lux. S.A.

IPR2017-00948, 2018 WL 3695200, at *30 (P.T.A.B. Aug. 1, 2018). 4 Eight months earlier in the IPR, in January 2018, Uniloc had filed a Motion to Amend, within the PTAB- specified due date, asking the PTAB to enter the Substitute Claims (claims 26–28) for independent claims 1, 22, and 25 if the PTAB found the latter unpatentable. See id. at *1; J.A. 310–51 (Motion to Amend); J.A. 313. Hulu opposed the Motion to Amend in February 2018, arguing, among other things, that the Substitute Claims are directed to pa- tent-ineligible subject matter under § 101. J.A. 386; see J.A. 381–413 (Opposition to Motion to Amend). Uniloc re- plied in March 2018 that Hulu was not permitted to raise a § 101 argument in opposition to the Substitute Claims, but did not respond with substantive arguments that its Substitute Claims meet the standards for eligibility under § 101. J.A. 508–09; see J.A. 495–512 (Reply to Motion to Amend). In its Final Written Decision, the PTAB, in addition to explaining why the challenged original claims are un- patentable, denied Uniloc’s Motion to Amend the claims, concluding that “[Hulu] ha[d] shown by a preponderance of the evidence that [the Substitute Claims] are directed to non-statutory subject matter under 35 U.S.C. § 101.” Final Written Decision, 2018 WL 3695200, at *30; id. at *24–27. Ineligibility was the sole ground on which the PTAB denied the motion to amend. The PTAB rejected Hulu’s other ob- jections to the Substitute Claims—obviousness in violation

4 In a related action, a district court invalidated all claims of the ’960 patent under § 101, upon concluding that they were “drawn to [patent-]ineligible subject matter,” Uniloc USA, Inc. v. Amazon.com, Inc., 243 F. Supp. 3d 797, 811 (E.D. Tex. 2017), and this court affirmed that judgment on August 9, 2018, after the Final Written Decision in the present IPR was issued, 733 F. App’x 1026 (Fed. Cir. 2018). Case: 19-1686 Document: 87 Page: 9 Filed: 07/22/2020

of § 103, enlargement of claim scope in violation of § 316(d), and indefiniteness in violation of § 112(a). Id. at *27–30. Uniloc requested a rehearing on August 31, 2018, J.A. 596–602 (Request for Rehearing), by which time this court had affirmed the federal-court judgment of invalidity of all original claims, see supra n.4. Uniloc argued that “[t]he PTAB misapprehended the law in concluding it is permissible in an IPR proceeding for the [PTAB] to con- sider a § 101 challenge” to its Substitute Claims. J.A. 597. As far as we have been shown, Hulu filed nothing at that point contending that the PTAB had lost any authority it had to consider the Substitute Claims given the final fed- eral-court invalidation of the original claims—a contention that would have called for vacatur of the Final Written De- cision rather than denial of rehearing. The PTAB denied Uniloc’s Request for Rehearing, concluding that § 101 eli- gibility may be considered by the PTAB in determining pro- posed substitute claim patentability in IPR proceedings. See Rehearing Denial, 2019 WL 343802, at *5. The USPTO Director designated the Rehearing Denial as precedential. See id. DISCUSSION I. Standard of Review and Legal Standard “We review the PTAB’s factual findings for substantial evidence and its legal conclusions de novo.” Redline Detec- tion, LLC v. Star Envirotech, Inc., 811 F.3d 435, 449 (Fed. Cir. 2015) (citation omitted). To determine whether the PTAB’s interpretation of the statute is in accordance with the law, we review the statute pursuant to the two-step Chevron analysis. See Nan Ya Plastics Corp. v. United States, 810 F.3d 1333, 1341 (Fed. Cir. 2016); see also Chev- ron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 467 U.S. 837, 842–43 (1984). When reviewing an agency’s con- struction of a statute, we must first determine “whether Congress has directly spoken to the precise question at is- sue.” Chevron, 467 U.S. at 842. If the answer is yes, then Case: 19-1686 Document: 87 Page: 10 Filed: 07/22/2020

the inquiry ends, and we “must give effect” to Congress’s unambiguous intent. Id. at 842–43; see Sullivan v. Stroop, 496 U.S. 478, 482 (1990) (“If the statute is clear and unam- biguous that is the end of the matter, for the court . . . must give effect to the unambiguously expressed intent of Con- gress.” (internal quotation marks and citation omitted)). We may find Congress has expressed unambiguous intent by examining “the statute’s text, structure, and legislative history, and apply[ing] the relevant canons of interpreta- tion.” Heino v. Shinseki, 683 F.3d 1372, 1378 (Fed. Cir. 2012) (internal quotation marks and citation omitted). If Congress has not directly spoken to the precise ques- tion at issue, we must consider “whether the agency’s an- swer [to the question] is based on a permissible construction of the statute.” Chevron, 467 U.S. at 843. The agency’s “interpretation governs in the absence of unam- biguous statutory language to the contrary or unreasona- ble resolution of language that is ambiguous.” United States v. Eurodif S.A., 555 U.S. 305, 316 (2009) (citing United States v. Mead Corp., 533 U.S. 218, 229–30 (2001)). II. The Case Is Not Moot In response to an order of this court directing the par- ties to address whether the case is moot, Hulu asserts that this court lacks jurisdiction on the ground of mootness. The Director and Uniloc disagree. We reject the mootness con- tention. We may dismiss a case for mootness “only if ‘it is im- possible for [us] to grant any effectual relief whatever’ to [Uniloc] assuming it prevails.” Mission Product Holdings, Inc. v. Tempnology, LLC, 139 S. Ct. 1652, 1660 (2019) (cit- ing Chafin v. Chafin, 568 U.S. 165, 172 (2013)). In this case, it is readily possible to grant Uniloc effectual relief if Uniloc is right on the merits. Uniloc’s appeal brief argues that the PTAB is statutorily barred from rejecting a Sub- stitute Claim based on § 101. If Uniloc is correct, it is en- titled to a certificate adding its Substitute Claims to Case: 19-1686 Document: 87 Page: 11 Filed: 07/22/2020

UNILOC 2017 LLC v. HULU, LLC 11

the ’960 patent, because the PTAB rejected all other grounds for finding unpatentability and Hulu has not chal- lenged the PTAB’s rulings in those respects. A judgment providing for addition of the Substitute Claims to Uniloc’s patent would be effectual relief. Hulu argues otherwise by making new arguments about how to read Uniloc’s contingent motion to amend and about the USPTO’s statutory authority. Specifically, Hulu contends that Uniloc’s motion to amend was not actually made “during the IPR” because it was contingent on the PTAB finding the original claims unpatentable—a finding that Hulu treats as ending the IPR. Relatedly, Hulu con- tends that, once the dispute in the IPR over the original claims was mooted by the final federal-court judgment of invalidity of those claims (which occurred after the Final Written Decision but before rehearing was sought), the USPTO lacked statutory authority to consider the proposed substitute claims. On these bases, Hulu suggests that the dispute over the Substitute Claims is moot because the statute precludes Uniloc from securing an addition of those claims to the patent. The Director, like Uniloc, disagrees. We reject Hulu’s arguments. First, under ordinary re- quirements for preservations of arguments, Hulu has waived these arguments. Before the PTAB, Hulu did not argue that the PTAB could not reach the motion to amend because the motion had to be read as resting on a contin- gency (finding the specified original claims unpatentable) that would already have ended the IPR. Nor did Hulu ar- gue to the PTAB in response to Uniloc’s petition for rehear- ing—which was filed after the federal-court invalidity judgment became final—that the Final Written Decision, or even just the part denying the motion to amend, must be vacated because the dispute over the original claims was moot and the PTAB had lost statutory authority to reach the proposed Substitute Claims. In this court, Hulu like- wise made no argument for lack of PTAB statutory author- ity to reach the Substitute Claims, either by filing a cross- Case: 19-1686 Document: 87 Page: 12 Filed: 07/22/2020

12 UNILOC 2017 LLC v. HULU, LLC

appeal to secure a vacatur of the PTAB’s rulings and dis- missal of the IPR or by presenting any such argument in its brief as Appellee, which simply sought affirmance. A question of an agency’s statutory authorization ordi- narily is not a nonwaivable “jurisdictional” issue. See PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1362 (Fed. Cir. 2018); see also Acoustic Tech., Inc. v. Itron Networked Solutions, Inc., 949 F.3d 1360, 1365 (Fed. Cir. 2020); Jal- bert v. SEC, 945 F.3d 587, 593–94 (1st Cir. 2019). Moreo- ver, in assessing whether there is an Article III case or controversy, a court ordinarily assumes the correctness of the plaintiff’s contentions on the merits. See, e.g., James v. J2 Cloud Servs., LLC, 887 F.3d 1368, 1372 (Fed. Cir. 2018); Rocky Mountain Helium, LLC v. United States, 841 F.3d 1320, 1325 (Fed. Cir. 2018); Macy v. GC Servs. Ltd. Pshp., 897 F.3d 747, 759 (6th Cir. 2018); Judicial Watch, Inc. v. Kerry, 844 F.3d 952, 954–55 (D.C. Cir. 2016). Here, if Uniloc is right in its argument about the PTAB’s statu- tory authority—that the PTAB has authority to entertain the substitute claims even once the original claims are fi- nally invalidated and that the PTAB lacks authority to con- sider § 101 before issuing the substitute claims—or if Uniloc has waived its first argument, then the Director (who agrees with Uniloc on that argument and has not ad- dressed waiver) would issue the substitute claims, giving Uniloc concrete relief. We need not decide if there is some exception to the or- dinary application of waiver principles here. In any event, we reject on the merits Hulu’s arguments that the PTAB lacked statutory authority to reach the Substitute Claims and the USPTO lacks statutory authority eventually to add those claims to the patent if we were to agree with Uniloc that § 101 eligibility is an impermissible ground for reject- ing substitute claims in an IPR. Hulu cites no authority for treating the contingent motion—as the USPTO treated it and as Hulu treated it until responding to this court’s directive to address mootness—as anything but a standard Case: 19-1686 Document: 87 Page: 13 Filed: 07/22/2020

UNILOC 2017 LLC v. HULU, LLC 13

form of in-the-alternative pleading, in which the second al- ternative, contingent on rejecting the first, is part of the proceeding and may be reached in the same decision as the first. As far as we have been shown, it would be unprece- dented, and contrary to the established practice of consid- ering contingent motions to amend, to treat the contingency (finding original claims unpatentable) as end- ing the IPR so that the proposed substitute claims could no longer be considered. Nothing in 35 U.S.C. § 316(d), or in other provisions of the statute, requires such a dramatic restriction on the availability of amendments in an IPR. Nor does the wording of Uniloc’s particular motion to amend—requesting consideration of the Substitute Claims if the PTAB “finds” specified original claims unpatentable, J.A. 313—require such a surprising conclusion. Similarly, Hulu has pointed to no statutory language that provides a basis for concluding that, once original claims no longer present a live dispute, the PTAB and the USPTO lose authority to consider proposed substitute claims that were presented in a contingent motion timely filed during the IPR when the original claims did present a live dispute. The USPTO treats such a request to consider proposed substitute claims as having an independent con- tinuing presence in the proceeding, not dependent on a live controversy continuing as to the original claims. That treatment is reasonable. Hulu points to no contrary au- thority. Indeed, the USPTO’s treatment is consistent with § 316(d)’s express contemplation that a patent owner may drop original claims and seek to replace them with substi- tute claims. It is consistent with the Manual of Patent Ex- amining Procedure’s description of the operation of ex parte reexamination, which has long allowed consideration of added claims to continue once original claims in reexam- ination have been held invalid in a final federal-court judg- ment. MPEP § 2286. Moreover, when Congress replaced the inter partes reexamination provisions with the IPR provisions in the AIA, Congress did not carry forward pre- Case: 19-1686 Document: 87 Page: 14 Filed: 07/22/2020

14 UNILOC 2017 LLC v. HULU, LLC

AIA § 317(b), concerning the termination of an inter partes reexamination based on parallel judicial proceedings. In reaching a contrary conclusion, the dissent relies on the word “substitute” in § 316(d), reasoning that there can- not be a substitute claim once the original claims have been finally been held invalid or cancelled. We disagree. The word “substitute” does not entail, as the dissent suggests it does, that the patentee must give what amounts to consid- eration—something of value—to obtain a replacement claim. Such a requirement is not necessitated by the ordi- nary meaning of “substitute” or by the use of the word in the IPR context, to which a notion of a bargain or exchange with the USPTO is foreign. The proposed replacement claims are “substitutes” no matter the value or continued existence of the original claims, as a replacement party is a “substitute” upon death of an original party. See Fed. R. Civ. P. 25(a); Fed. R. App. P. 43(a). In short, we see no mootness impediment to our juris- diction to consider Uniloc’s statutory contention about PTAB authority to consider § 101 eligibility for proposed substitute claims. As explained next, we conclude that the PTAB was authorized by statute to assess Uniloc’s pro- posed Substitute Claims for eligibility under § 101 and, finding the claims ineligible, to deny the motion to amend. III. The Text, Structure, and Legislative History of the IPR Statutes Confirm that the PTAB May Review Pro- posed Substitute Claims for Patent Eligibility The PTAB denied Uniloc’s Motion to Amend the ’960 patent, concluding that the Substitute Claims were di- rected to patent-ineligible subject matter under 35 U.S.C. § 101. See Final Written Decision, 2018 WL 3695200, at *30. The PTAB concluded that, under the IPR Statutes, it is permitted to review and deny proposed substitute claims during IPR proceedings for patent ineligibility pur- suant to § 101. See Rehearing Denial, 2019 WL 343802, at *5. Uniloc contends that “[t]he [PTAB] erred as a matter Case: 19-1686 Document: 87 Page: 15 Filed: 07/22/2020

UNILOC 2017 LLC v. HULU, LLC 15

of law” by basing its denial of the Motion to Amend on its § 101 determination. Appellant’s Br. 13. Specifically, Uniloc argues that the PTAB is limited in its review of pro- posed substitute claims to anticipation or obviousness, as provided by § 311(b). Id. at 14. We disagree with Uniloc. The PTAB correctly concluded that it is not limited by § 311(b) in its review of proposed substitute claims in an IPR, and that it may consider § 101 eligibility. The deter- mination is supported by the text, structure, and history of the IPR Statutes, which indicate Congress’s unambiguous intent to permit the PTAB to review proposed substitute claims more broadly than those bases provided in § 311(b). See Chevron, 467 U.S. at 842. First, the text of the IPR Statutes supports the conclusion that the PTAB may con- sider § 101 eligibility when reviewing substitute claims. The IPR Statutes plainly and repeatedly require the PTAB to determine the “patentability” of proposed substitute claims. Section 318 requires the PTAB “issue a final writ- ten decision with respect to the patentability of . . . any new claim added under [§] 316(d).” 35 U.S.C. § 318(a) (empha- sis added). It further provides that “the Director shall is- sue and publish a certificate . . . incorporating in the patent by operation of the certificate any new or amended claim determined to be patentable.” Id. § 318(b) (emphasis added). Moreover, it states that “[a]ny proposed amended or new claim determined to be patentable and incorporated into a patent following an [IPR]” will “have the same effect as” if it had been originally granted. Id. § 318(c) (emphasis added) (incorporating by reference 35 U.S.C. § 252). As we have concluded, a § 101 analysis constitutes a “patentabil- ity” determination. See Versata Dev. Grp., Inc. v. SAP Am., Inc., 793 F.3d 1306, 1329–31 (Fed. Cir. 2015) (explaining that the use of the phrase “conditions of patentability” in the AIA extends to § 101 challenges); see also id. at 1330 (“[B]oth our opinions and the Supreme Court’s opinions over the years have established that § 101 challenges [are] . . . patentability challenges.”); Aristocrat Techs.

Austl. Ltd. v. Int’l Game Tech., 543 F.3d 657, 661 (Fed. Cir. 2008) (“It has long been understood that the Patent Act sets out the conditions for patentability in three sec- tions: [§§] 101, 102, and 103.” (citing Graham v. John Deere, 383 U.S. 1, 12 (1966))). The plain language of the IPR Statutes demonstrates Congress’s intent for the PTAB to review proposed substitute claims for overall “patenta- bility”—including under § 101—of the claims. Despite Uniloc’s claim to the contrary, see Appellant’s Br. 14, Congress did not intend § 311 to constrain the PTAB’s review of proposed substitute claims to anticipa- tion and obviousness, pursuant to § 102 and § 103, respec- tively, excluding other invalidity issues, such as those that might arise under § 101. Section 311 is confined to the re- view of existing patent claims, not proposed ones: it limits “[a] request to cancel as unpatentable [one] or more claims of a patent” to a “ground that could be raised under [§] 102 or [§] 103[.]” 35 U.S.C. § 311(b) (emphases added). The plain language of the statute limits the provision to the IPR petitioner’s “request to cancel” a claim that is “of a patent,” but it does not so limit the PTAB’s evaluation of proposed substitute claims. Id. To “cancel” carries the ordinary meaning to “annul or destroy[,]” Mac’s Shell Serv., Inc. v. Shell Oil Prods. Co., 559 U.S. 175, 183 (2010) (internal quo- tation marks and citation omitted); see WEBSTER’S THIRD NEW INTERNATIONAL DICTIONARY (1961) (providing the def- inition of “cancel” as the “destr[uction] [of] the force, effec- tiveness, or validity”), which presupposes that which is being “cancelled” is already in effect. In § 311(b), the infin- itive “to cancel” is followed by its direct object, the phrase “[one] or more claims[.]” 35 U.S.C. § 311(b); see id. (“A pe- titioner in an [IPR] may request to cancel . . . [one] or more claims[.]”). When given its ordinary meaning, § 311(b) pro- vides that only claims that are in effect may be annulled. In an IPR, only the preexisting claims of the at-issue patent are in effect, as an IPR petition may only be brought of an already issued patent. See id. § 311(a) (“[A] person who is Case: 19-1686 Document: 87 Page: 17 Filed: 07/22/2020

UNILOC 2017 LLC v. HULU, LLC 17

not the owner of a patent may file with the [USPTO] a pe- tition to institute an [IPR] of the patent.”). In the case of a substitute claim, there is no such prior “force, effectiveness, or validity,” as the substitute claim has never been ap- proved or issued by the USPTO. See id. § 318(a), (b). Re- latedly, a substitute claim is not part “of the patent,” as it has not been previously approved and issued by the USPTO, as § 318 itself expresses that a substitute claim shall be “incorporat[ed] in the patent” only after it is “de- termined to be patentable.” 35 U.S.C. § 318(b). Therefore, a substitute claim that has not been issued cannot be “can- cel[ed],” and so is not “of the patent” when proposed by the patent owner. Id. Accordingly, the limits of § 311(b) do not extend to the PTAB’s review of proposed substitute claims. Second, the structure and legislative history of the IPR Statutes support this conclusion. Regarding structure, the IPR Statutes proceed in chronological order from the IPR petition, to institution, and adjudication: §§ 311–313 pro- vide the rules for filing a petition, § 314 and § 315 address criteria for institution, § 316 guides trial conduct, and §§ 317–319 relate to settlements, final written decisions, and appeals. Section 311, as a provision applying to the petition phase of the proceedings, should not therefore bind a separate adjudication-stage provision, such as § 316. The IPR Statutes’ legislative history also confirms that the PTAB is permitted to review proposed substitute claims for patentability outside of anticipation and obvi- ousness. “Reexamination proceedings . . . are intended to ‘permit any party to petition the [US]PTO to review the ef- ficacy of a patent, following its issuance, on the basis of new information about preexisting technology that may have escaped review at the time of the initial examination.’” In re NTP, Inc., 654 F.3d 1268, 1275 (Fed. Cir. 2011) (altera- tion omitted) (quoting H.R. REP. No. 66-1307, 96th Cong., 2d Sess. (1980), at 3–4). As we explained in NTP, “[t]he scope of reexamination proceedings is limited to ‘sub- stantial new question[s] of patentability,’ 35 U.S.C. Case: 19-1686 Document: 87 Page: 18 Filed: 07/22/2020

18 UNILOC 2017 LLC v. HULU, LLC

§ 303(a) [(2006)], which are questions that have not previ- ously been considered by the [US]PTO,” NTP, 654 F.3d at 1275 (citation omitted). While we noted that the request for reexamination under § 302 may be based only on prior art citations and the patent owner’s written statements, id. (citing 35 U.S.C. §§ 301, 302), we cabined the scope of these limitations to the patent’s “original claims,” stating that “other challenges to the patentability of original claims— such as qualification as patentable subject matter under § 101 . . . —may not be raised in reexamination proceed- ings[,]” id. at 1275–76 (citing 35 U.S.C. §§ 301, 302) (em- phasis added). Moreover, we concluded that “[t]here is no statutory limitation during a reexamination proceeding prohibiting the examiner from conducting a priority analy- sis[,]” under 35 U.S.C. § 120, as a prohibition on such anal- ysis would “strip[] [the examiner] of a critical legal tool needed in performing a proper reexamination.” Id. at 1277. As we explained in NTP, it was Congress’s intent to permit the PTAB to address issues that “have escaped review at the time of the initial examination.” Id. at 1275 (quoting H.R. REP. No. 66-1307, 96th Cong., 2d Sess. (1980), at 3–4). Proposed substitute claims in an IPR proceeding have not undergone a patentability review by the USPTO, see 35 U.S.C. § 316, and so the “substantial new questions of pa- tentability” that “have not previously been considered by the [US]PTO” include all patentability questions, including § 101 patent eligibility, NTP, 654 F.3d at 1275 (internal quotation marks, alteration, and citations omitted). Pro- hibiting the PTAB from reviewing patent eligibility would indeed “strip[] [the PTAB] of a critical legal tool[.]” Id. at 1277. While NTP addressed pre-AIA reexamination pro- ceedings, its reasoning is applicable here, as the underlying motivation for an IPR proceeding did not change with the AIA. Regents, 926 F.3d at 1335 (explaining that “[a]lthough Congress changed the name from ‘reexamina- tion’ to ‘review,’” the “basic purposes” of “reexamin[ing] an earlier agency decision” remained); see H.R.

pt. I, at 46–47 (2011) (explaining that the AIA’s alterations to the inter partes reexamination includes an “expan[sion] [of] the category of documents that may be cited” to, a “con- ver[sion] [of the] inter partes reexamination from an exam- inational to an adjudicative proceeding,” and a number of “improvements to th[e] proceeding”); USPTO REPORT TO CONGRESS ON INTER PARTES REEXAMINATION (2004), at 1 (recommending three areas of improvement to the inter partes reexamination process by: clarifying estoppel provi- sions, providing petitioners with additional opportunities to provide input, and extending statutory deadlines). Moreover, § 311 is premised on the pre-AIA reexamination statute, providing analogous language and a comparable procedural position to the pre-AIA reexamination statute. Compare 35 U.S.C. § 311 (2012) (providing that a petitioner “may file with the [USPTO] a petition to institute an [IPR] of the patent[,]” “request[ing] to cancel as unpatentable [one] or more claims of a patent only on a ground that could be raised under [§] 102 or [§] 103 and only on the basis of prior art consisting of patents or printed publications”), with 35 U.S.C. § 302 (2006) (“Any person at any time may file a request for reexamination by the [USPTO] of any claim of a patent on the basis of any prior art cited under the provisions of [§] 301[.]”); see id. § 301 (2006) (providing prior art as “consisting of patents or printed publications which [the petitioner] believes to have a bearing on the pa- tentability of any claim of a particular patent”). As the USPTO explains, “if a patent owner seeking amendments in an IPR were not bound by § 101 and § 112, then in virtually any case, it could overcome prior art and obtain new claims simply by going outside the boundaries of patent eligibility and the invention described in the spec- ification[,]” Intervenor Br. 25, allowing patents with other- wise invalidated claims “to return from the dead as IPR amendments[,]” id. at 26. Because the proposed substitute claims have not been assessed for patentability by the USPTO, the PTAB achieves the purpose set forth by Case: 19-1686 Document: 87 Page: 20 Filed: 07/22/2020

20 UNILOC 2017 LLC v. HULU, LLC

Congress to review “substantial new questions of patenta- bility” based on claims “that have not previously been con- sidered by the [US]PTO.” NTP, 654 F.3d at 1275 (internal quotation marks, alteration, and citations omitted). In- deed, Uniloc has not identified any other context under Ti- tle 35—e.g., original applications, reexaminations, reissue, etc.—in which the USPTO is required or authorized to newly issue a patent claim without ever having determined that the particular claim meets the statutory requirements for patentability. The result suggested by Uniloc—that the USPTO must issue the Substitute Claims without consid- ering § 101, and leave consideration of eligibility to post- issuance challenges—would therefore be grossly out of keeping with the statutory regime as a whole. The PTAB correctly concluded that it may consider § 101 patent eligi- bility when considering the patentability of proposed sub- stitute claims in an IPR. 5 Uniloc contends that our decision in Aqua Products Inc. v. Matal, 872 F.3d 1290 (Fed. Cir. 2017) (en banc), fore- closes the review of its Substitute Claims under § 101, see Appellant’s Br. 19–21. Specifically, Uniloc, in quoting the Aqua Products plurality, argues that because “[t]he struc- ture of an IPR does not allow the patent owner to inject a wholly new proposition of unpatentability into the IPR by proposing an amended claim[,]” and as a substitute claim must be narrower than the claim it replaces, “[w]hen the

5 As the text, structure, and history of the IPR Stat- utes are unambiguous, we need not reach the issue of def- erence to the USPTO’s interpretation of the statute set forth in its precedential decision. See Nan Ya Plastics Corp., 810 F.3d at 1341 (“If Congress’s intent is clear, ‘that is the end of the matter; for the court, as well as the agency, must give effect to the unambiguously expressed intent of Congress.’” (quoting Chevron, 467 U.S. at 842–43)); see also Rehearing Denial, 2019 WL 343802, at *5.

petitioner disputes whether a proposed amended claim is patentable, it simply continues to advance a ‘proposition of unpatentability’ in an ‘[IPR] instituted under this chap- ter.’” Id. at 19 (quoting Aqua Prods., 872 F.3d at 1306 (quoting 35 U.S.C. § 316(e))). No opinion in Aqua Products garnered a majority, leaving the only holding as a burden of proof determination, concluding that the USPTO had im- properly adopted regulations assigning the burden of proof with respect to proposed substitute claims. 872 F.3d at 1327–28. The Aqua Products language Uniloc relies upon addresses only whether a petitioner challenging the proposed substitute claims bears § 316(e)’s burden of proof. Appellant’s Br. 19–21; see Aqua Prods., 872 F.3d at 1306 (addressing whether the language of § 316(e), which all conceded applied to challenged claims, “applies equally to proposed substitute claims”). Aqua Products is silent as to whether a petition may raise a patent-ineligibility chal- lenge to a proposed substitute claim. Accordingly, Aqua Products does not foreclose the PTAB’s § 101 review of Uniloc’s Substitute Claims and subsequent denial of Uniloc’s Motion to Amend. CONCLUSION We have considered Uniloc’s remaining arguments— including its argument that it should be given a second chance to address § 101 on the merits in the USPTO, hav- ing bypassed the full opportunity it already had—and find them unpersuasive.

Appeal from the United States Patent and Trademark Office, Patent Trial and Appeal Board in No. IPR2017- 00948. ______________________

O’MALLEY, Circuit Judge, dissenting. Typically, when this court has finally adjudged a pa- tent claim invalid, it also refuses to consider any appeal that demands relief dependent on that claim and vacates any such relief that has been awarded by another tribunal. See e.g., ePlus, Inc. v. Lawson Software, Inc., 789 F.3d 1349, 1361 (Fed. Cir. 2015); Fresenius USA, Inc. v. Baxter Int’l, Inc., 721 F.3d 1330, 1347 (Fed. Cir. 2013); see also Chrimar Case: 19-1686 Document: 87 Page: 23 Filed: 07/22/2020

Sys., Inc. v. ALE USA Inc., 785 F. App’x 854, 856 (Fed. Cir. 2019), cert. denied, No. 19-1124, 2020 WL 3492668 (U.S. June 29, 2020). Here, rather than follow that usual proce- dure, the majority breathes life into a dead patent and uses the zombie it has created as a means to dramatically ex- pand the scope of inter partes review (“IPR”) proceedings. Because the Patent Trial and Appeal Board (“Board”) is es- topped from issuing substitute claims in place of the inval- idated claims of U.S. Patent No. 8,566,960 (“’960 patent”) and because, even if the Board could issue such claims, it would be improper for it to consider 35 U.S.C. § 101, I re- spectfully dissent. I In 2016, Uniloc 1 filed several lawsuits in the Eastern District of Texas, alleging that Hulu, LLC and Netflix, Inc. (“petitioners”), among others, infringed the claims of the ’960 patent. See Uniloc USA, Inc. v. Amazon.com, Inc., 243 F. Supp. 3d 797 (E.D. Tex. 2017). In March 2017, the dis- trict court dismissed the cases for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6), holding all claims of the ’960 patent ineligible for patenting under § 101. Id. at 811. Uniloc appealed, and, on August 9, 2018, we summarily affirmed the district court’s decision. See Uniloc USA, Inc. v. Amazon.com, Inc., 733 F. App’x 1026 (Fed. Cir. 2018). Uniloc did not seek Supreme Court re- view.

1 The “Uniloc” entities that filed suit in district court are named Uniloc USA, Inc. and Uniloc Luxembourg S.A. Appellant in this case is Uniloc 2017 LLC. The technical separateness of those entities’ corporate identities is not relevant to this appeal; there is no dispute that the real parties in interest are the same in both proceedings. I thus refer to all as “Uniloc” throughout. Case: 19-1686 Document: 87 Page: 24 Filed: 07/22/2020

Prior to the district court’s dismissal of Uniloc’s in- fringement actions, petitioners filed a petition for IPR with the Board, challenging all claims of the ’960 patent as an- ticipated or obvious over the prior art. The Board insti- tuted on all claims and grounds. Uniloc filed a patent owner response and a contingent motion to amend the in- dependent claims. The Board issued a final written deci- sion (“FWD”) on August 1, 2018. It held that petitioners had proven the unpatentability of original claims 1–8, 18– 22, and 25, but had not proven the unpatentability of orig- inal claims 9–17, 23, and 24. The Board further denied Uniloc’s motion to amend, holding that those claims, while not otherwise unpatentable over the prior art and other- wise satisfying the statutory and regulatory prerequisites to amendment, were patent ineligible. In its FWD, the Board stated that it had previously ad- dressed § 101 grounds in the IPR context, citing Western Digital Corp. v. Spex Technologies, Inc., 2018 WL 1989599, at *2–3 (P.T.A.B. Apr. 25, 2018); Ariosa Diagnostics v. Isis Innovation Ltd., 2014 WL 4381564, at *31–32 (P.T.A.B. Sept. 2, 2014). J.A. 58–59. It then said that, in its view, it made sense to do so when evaluating proposed substitute claims, in addition to addressing the §§ 102 and 103 grounds raised in the petition. 2

2 The Board’s reference to Western Digital and Ari- osa is curious. In Western Digital, the Board addressed whether a narrowing amendment that coincidentally ap- pears to correct a potential § 101 problem in a challenged claim (for example, a problem identified in a parallel dis- trict court proceeding) would be improper. W. Dig. Corp., 2018 WL 1989599, at *2–3. The Board simply held that, where the amendment satisfies the statutory and regula- tory criteria for amendments in an IPR, the mere fact that it might also help avoid a separate § 101 challenge is not disqualifying. Id. It said nothing about whether a Case: 19-1686 Document: 87 Page: 25 Filed: 07/22/2020

Uniloc requested rehearing as to only the proposed amended claims, which the Board denied on January 18, 2019. In its denial, the Board engaged directly with the statutory language. It focused first on the language of 35 U.S.C. § 311(b): A petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a pa- tent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications. The Board explained that § 311(b) governs the petition, not the petitioner’s response to a patent owner’s motion to amend. Section 316(d), the statutory provision allowing for amendment, it reasoned, is not limited to §§ 102 and 103. In the Board’s view, the distinction between the grounds for challenging original claims and substitute claims is fur- ther reinforced by the treatment of the claims in § 318. J.A.

petitioner or the Board itself could raise a § 101 challenge to an otherwise compliant amendment. The citation to Ariosa fares no better. There, the Board’s entire discussion was premised on the conclusion that the patent owner had the obligation to prove patenta- bility of its amendment—answering any questions about its propriety in that context, including § 101 questions posed in a district court proceeding. See Ariosa Diagnos- tics, 2014 WL 4381564, at *31–32. But, Ariosa predates Aqua Products v. Matal, 872 F.3d 1290 (Fed. Cir. 2017), where we made clear that the burden to prove patentability of a proposed amendment could not be placed on the patent owner precisely because the petitioner had the burden of establishing invalidity under the grounds asserted in the petition, which are limited by statute to challenges under §§ 102 and 103. Notably, the majority does not cite either to support its conclusion. Case: 19-1686 Document: 87 Page: 26 Filed: 07/22/2020

77 (“Section 318(b) . . . reiterates this distinction, providing that, if we issue a final written decision, ‘the Director shall issue and publish a certificate canceling any claim of the patent finally determined to be unpatentable, confirming any claim of the patent determined to be patentable, and in- corporating in the patent by operation of the certificate any new or amended claim determined to be patentable.’”) (em- phases in original). The Board further reasoned that its ability to consider § 101 is consistent with its practice of considering § 112 when deciding proposed amended claims. The Board thus concluded that nothing precludes it from evaluating substi- tute claims through the §101 lens and declined rehearing. The Board’s denial of Uniloc’s request for rehearing was designated as precedential. Uniloc appeals. II As an initial matter, contrary to the conclusion reached by the majority, this case is moot. “[A]n appeal should . . . be dismissed as moot when, by virtue of an intervening event, a court of appeals cannot grant any effectual relief whatever in favor of the appellant.” Calderon v. Moore, 518 U.S. 149, 150 (1996) (quotation marks omitted). The ma- jority asserts that, in the event Uniloc is successful on the merits, there is some possibility of relief. Maj. 11. My col- leagues are mistaken. In this case, relief is possible only if, in the event of a remand, the Board has authority to issue substitute claims. See 35 U.S.C. § 316(d)(1)(B) (allowing a patentee to “pro- pose a reasonable number of substitute claims”); § 318(a)– (b) (governing the incorporation of claims added via the op- eration of § 316(d)); 37 C.F.R. § 42.121(a)(3) (“The pre- sumption is that only one substitute claim would be needed to replace each challenged claim . . . .” (emphasis added)) . Completing such a substitution requires that there be Case: 19-1686 Document: 87 Page: 27 Filed: 07/22/2020

original claims to substitute out for the new claims—i.e., in the words of the Patent Office itself, the patentee must “re- place” a challenged claim with a substitute. 3 See Substi- tute, Oxford English Dictionary (3d ed., 2012 update) (“An object, practice, action, etc., which takes the place of an- other; a replacement”); Substitution, Oxford English Dic- tionary (3d ed., 2012 update) (“The action or an act of putting one person or thing in place of another; the fact of being put in another’s place.”). In the context of an IPR, this means that, in exchange for a substitute claim, a pa- tent owner must be capable of relinquishing a patent right. This is a necessary part of the statutory scheme, moreover, as it ensures that the claims issued from IPR, having not

3 The majority contends that its understanding of the statutory scheme on this point is consistent with the United States Patent Office’s treatment of similarly situ- ated claims in inter partes reexamination proceedings. Maj. 13 (citing MPEP § 2286). Inter partes reexamination proceedings are, however, governed by entirely different statutory language than the language relevant here. In an inter partes reexamination, “the patent owner shall be per- mitted to propose any amendment to the patent and a new claim or claims, except that no proposed amended or new claim enlarging the scope of the claims of the patent shall be permitted.” 35 U.S.C. § 314(a) (pre-AIA). In the IPR context the Board is not merely considering “new” claims, it is considering proposed “substitute claims.” § 316(d)(1)(B). A substitute is of an entirely different char- acter than something new. The Board itself has said that, for this reason, “[a]n inter partes review is neither a patent examination proceeding nor a patent reexamination pro- ceeding.” Ariosa Diagnostics, 2014 WL 4381564, at *30. And, that “proposed substitute claims will be added di- rectly to the patent, without examination, if the patent owner’s motion to amend is granted.” Id. (emphasis omit- ted). Case: 19-1686 Document: 87 Page: 28 Filed: 07/22/2020

themselves undergone a separate examination, share a di- rect lineage from claims that were not otherwise invali- dated on non-102 and 103 grounds. After our affirmance of the district court’s ineligibility determination, and once the time expired for Uniloc to seek Supreme Court review of that affirmance, it did not possess any patent rights that it could give up in exchange for a substitute claim. It owned nothing and could not, there- fore, substitute its old claims for new ones. 4 If Uniloc were to prevail in this appeal and return to the Board, the Board would be without power to effectuate a substitution. The finality of our invalidity judgment should therefore be the end of the inquiry in this case. See Fresenius, 721 F.3d at 1344 (explaining that, based on the structure of the stat- utes governing IPRs, a final judgment of invalidity in one proceeding forecloses relief based on a patent claim in a parallel proceeding). Despite a final judgment of invalidity of all original claims of the ’960 patent, the majority declares, without ex- planation, that the Board could grant Uniloc the relief it requests and proceeds to focus its entire analysis on the contingent nature of Uniloc’s motion to amend. Maj. 10– 14. Although I agree with the majority that the contingent nature of the motion to amend is unimportant, I do not agree with the majority that Appellees somehow waived any argument that this matter is moot by not raising this

4 To analogize to ownership of real property, if a court finally determines that a deed to property is defective such that the property belongs to someone else, the former “owner” cannot “substitute” that property for a new par- cel—even if the owner is in the middle of closing a sale. The former “owner” has nothing to give up and, indeed, never had anything to bargain with in the first place. Case: 19-1686 Document: 87 Page: 29 Filed: 07/22/2020

issue prior to our invitation to address it. 5 Because moot- ness implicates Article III’s case or controversy require- ment—a threshold jurisdictional issue—a party cannot waive it. See Genesis Healthcare Corp. v. Symczyk, 569 U.S. 66, 71–72 (2013); Iron Arrow Honor Soc’y v. Heckler, 464 U.S. 67, 70 (1983). It is, moreover, well established that threshold jurisdictional questions can be raised at any time. Schering Corp. v. United States, 626 F.2d 162, 167 (C.C.P.A. 1980). And we have a duty to independently

5 The majority contends, “[a] question of an agency’s statutory authorization ordinarily is not a nonwaivable ‘ju- risdictional’ issue.” Maj. 11. The issue of our jurisdiction is distinct from a challenge to the agency’s authority. While, for example, a party may waive an argument that an agency did not have authority to institute on only some grounds raised in a petition, see PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1361–62 (Fed. Cir. 2018), or an argu- ment that a petition was untimely filed, see Acoustic Tech., Inc. v. Itron Networked Sols., Inc., 949 F.3d 1360, 1365 (Fed. Cir. 2020), it cannot waive an argument that we lack jurisdiction based on mootness resulting from a proper un- derstanding of what relief, if any, the Board could provide in the event of a remand. The majority further asserts, “in assessing whether there is an Article III case or controversy, a court ordinarily assumes the correctness of the plaintiff’s contentions on the merits.” Maj. 12. Three of the cases cited by the majority address standing, not mootness. See James v. J2 Cloud Servs., LLC, 887 F.3d 1368, 1372 (Fed. Cir. 2018); Rocky Mountain Helium, LLC v. United States, 841 F.3d 1320, 1325 (Fed. Cir. 2018); Macy v. GC Servs. Ltd, 897 F.3d 747, 759 (6th Cir. 2018). None stand for the proposition that we must assume that a plaintiff is correct in its interpretation of a statute. See, e.g., Judicial Watch, Inc. v. Kerry, 844 F.3d 952, 954–55 (D.C. Cir. 2016) (discussing factual alle- gations). Case: 19-1686 Document: 87 Page: 30 Filed: 07/22/2020

inquire into our jurisdiction, even absent a party raising the issue. Yarway Corp. v. Eur-Control USA, Inc., 775 F.2d 268, 273 (Fed. Cir. 1985). The majority’s focus on Appel- lees’ failure to raise their mootness arguments earlier is, therefore, misplaced. The majority further places a great deal of weight on whether the Board has authority to issue substitute claims in an ongoing IPR after it holds the original claims invalid. This misses the point. The issue before us is not the extent to which the Board can consider a contingent motion to amend, in an ongoing, non-final IPR. Rather, the question we must answer is whether the Board can consider a re- quest to substitute claims where, in a parallel proceeding with a final judgment, the original claims have been held invalid. As I explain above, the final judgment forecloses consideration of the merits of this appeal and should be given proper effect. 6

6 It is also worth noting that the majority’s determi- nation that this IPR can continue, after a final judgment of invalidity in the district court case, is inconsistent with re- cent policy statements adopted by the Board. In a prece- dential opinion, the Board announced six factors to consider when deciding whether it should exercise its dis- cretion to institute an IPR when a parallel district court case is ongoing: 1. whether the court granted a stay or evidence ex- ists that one may be granted if a proceeding is in- stituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written de- cision; 3. investment in the parallel proceeding by the court and the parties; Case: 19-1686 Document: 87 Page: 31 Filed: 07/22/2020

III After concluding that an invalid patent can serve as a vehicle to reach the merits of this appeal, the majority an- nounces that, when it comes to substitute claims, the Board can engage in a full-blown examination. This revelation runs contrary to the plain language of the statute and the policy of efficiency that underlies the IPR system. A The America Invents Act (“AIA”) IPR provisions estab- lish a clear and intuitive structure for efficiently processing claims challenged by a petitioner. 35 U.S.C. §§ 311–319. Section 311(b) establishes the “scope” of inter partes re- view. A petitioner “may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” § 311(b).

4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s ex- ercise of discretion, including the merits. Apple Inc., v. Fintiv, Inc., No. IPR2020-00019, 2020 WL 2126495, at *2 (P.T.A.B. Mar. 20, 2020). These discretion- ary factors strongly indicate that the Board views parallel district court cases as highly relevant to the continued rel- evance of an IPR proceeding. Where, as here, the district court proceeding has eliminated all the claims subject to the IPR, the Board’s own policy supports declaring that IPR over. Case: 19-1686 Document: 87 Page: 32 Filed: 07/22/2020

After institution, § 316, titled “Conduct of Inter Partes Review,” controls the proceeding and includes a subsection that allows a patentee to amend its patent by either (1) canceling any challenged claim or (2) proposing a rea- sonable number of substitute claims for any challenged claim. § 316(d)(1). The substitute claims “may not enlarge the scope of the claims of the patent or introduce new mat- ter.” § 316(d)(3). The governing regulations, implementing the limitations set out in § 316(d)(3), provide that the Board may deny a motion to amend if the amendment does not satisfy the statutory requirements—i.e., if it expands the claim scope, introduces new matter, or if it “does not respond to a ground of unpatentability involved in the trial.” 37 C.F.R. § 42.121(a)(2); see also Aqua Prod., Inc. v. Matal, 872 F.3d 1290, 1301 (Fed. Cir. 2017). Governing the end of IPR proceedings, § 318 is titled “Decision of the Board.” It provides, “[i]f an inter partes review is instituted and not dismissed under this chapter, the [Board] shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner and any new claim added under section 316(d).” § 318(a) (emphasis added). It also requires the Director to issue a certificate in accordance with the decision, once the decision is final. § 318(b). The majority focuses narrowly on the literal text of the three provisions discussed above and fails entirely to con- tend with the clear framework of the IPR provisions. Plain language interpretation requires more than cherry picking provisions out of context. We “must read the words ‘in their context and with a view to their place in the overall statu- tory scheme.’” King v. Burwell, 135 S. Ct. 2480, 2483, 192 L. Ed. 2d 483 (2015) (quoting FDA v. Brown & Williamson Tobacco Corp., 529 U.S. 120, 133 (2000)). The majority starts with the text of § 318 and so will I. The majority contends that the term “patentability” should be understood as having two distinct meanings in the Case: 19-1686 Document: 87 Page: 33 Filed: 07/22/2020

context of § 318. Maj. 14–16. That is, the majority takes the position that “patentability,” which appears only once in the relevant provision, means one thing as to “any pa- tent claim challenged by the petitioner” and something en- tirely different as to “any new claim added under section 316(d).” See § 318(b). Understanding a single word to con- vey two different meanings in a statute is inconsistent with basic principles of statutory interpretation. Cf. Credit Ac- ceptance Corp. v. Westlake Servs., 859 F.3d 1044, 1053 (Fed. Cir. 2017) (“The normal rule of statutory interpreta- tion is that identical words used in different parts of the same statute are generally presumed to have the same meaning.” (brackets omitted) (quoting IBP, Inc. v. Alvarez, 546 U.S. 21, 22 (2005))). Thus, although outside the spe- cific context of this statutory scheme we have stated that § 101 is a patentability provision, see Aristocrat Techs. Austl. Ltd. v. Int’l Game Tech., 543 F.3d 657, 661 (Fed. Cir. 2008), that fact cannot control here. Instead, we must discern an appropriate, single meaning for a term that is used only once in § 318(a). The sole meaning of patentabil- ity must be, therefore, the one contemplated by § 311(b). Even the majority agrees that, as to challenged claims, “pa- tentability” means patentability over §§ 102 and 103 grounds based on limited categories of prior art. Absent some clear intent to give a single word two highly different meanings, we must give “patentability” one meaning in this statute. The meaning that undisputedly applies to challenged claims is the one we must apply universally. 7

7 I recognize that § 318(b) further provides “the Di- rector shall issue and publish a certificate . . . incorporating in the patent by operation of the certificate any new or amended claim determined to be patentable.” 35 U.S.C. § 318(b) (emphasis added). This additional language, how- ever, is clearly in reference to § 318(a), cannot be read as expanding the scope of the Board’s review, and is identical Case: 19-1686 Document: 87 Page: 34 Filed: 07/22/2020

The majority, notably citing no legislative history, next declares, “Congress did not intend § 311 to constrain the [Board’s] review of proposed substitute claims to anticipa- tion and obviousness . . . .” Maj. 16. In support of this conclusion, my colleagues parse the language of § 311(b)— explaining that the provision only applies to those claims which may be canceled. Id. at 16–17. This discussion is beside the point and says nothing about Congress’s intent as to the scope of patentability issues that may be consid- ered in an IPR. It is true that a petitioner may only chal- lenge and seek to cancel issued claims in a petition—unless the petitioner is clairvoyant it could not possibly do more. That undisputed truth does not, however, speak to whether Congress intended the limitations on “scope” found in § 311(b) to apply to substitute claims. Looking at the statutory framework as a whole, “[t]he structure of an IPR does not allow the patent owner to in- ject a wholly new proposition of unpatentability into the IPR by proposing an amended claim.” Aqua Prod., Inc., 872 F.3d 1290, 1306 (Fed. Cir. 2017). The patent owner may only propose narrowed claims that address the issues raised in the petition. See 37 C.F.R. § 42.121(a)(2). Con- trary to the conclusion the majority reaches by cabining the IPR “scope” provision, the overall structure indicates that Congress intended to limit the Board’s authority to a re- view of the specified patentability grounds. To the extent the “chronological” nature of the IPR Statutes bears on this question, § 311 comes first, setting the parameters of what may be considered throughout the proceeding. Substitute claims come into existence only after the scope of the IPR has been set. It follows that Congress did not need to rearticulate a parameter already expressed in prior provi- sions: IPRs are limited to §§ 102 or 103 and to prior art

to the language the provision uses when addressing chal- lenged claims. Case: 19-1686 Document: 87 Page: 35 Filed: 07/22/2020

consisting of patents or printed publications. And, as dis- cussed above, the fact that Congress failed to describe sep- arate standards for evaluating challenged claims and substitute claims conclusively supports such an under- standing Still reaching for history (legislative or otherwise) to support its position, the majority moves to the history of pre-AIA reexamination proceedings. Maj. 17–18. Much like the majority’s consideration of claims that can be can- celed in an IPR, the majority’s discussion of reexamination is irrelevant to the question of whether § 101 is properly considered in the context of an IPR. Reexamination, as is clear from its name, is by its very nature an examination with a different scope than IPRs. See discussion supra note 3. To justify its rationale, the majority looks to In re NTP, Inc., 654 F.3d 1268 (Fed. Cir. 2011), for support; they find very little. In NTP, we held, consistent with the reexami- nation statutes, that § 101 was not an appropriate patent- ability challenge to raise in reexamination and reached the innocuous conclusion that “[t]here is no statutory limita- tion during a reexamination proceeding prohibiting the ex- aminer from conducting a [§ 120] priority analysis.” Id. at 1275–77. But § 120 is not a patentability provision (which appear in Chapter 10 of Title 35, entitled “Patentability of Inventions”). Rather, § 120 is a procedural provision fall- ing under Chapter 11 of Title 35, “Application for Patent.” Our statement in NTP that the Board had access to a nec- essary tool for considering a patent’s priority is thus not the least bit relevant to the scope of the Board’s substantive authority for examining patentability. See id. at 77. What is relevant is the language of the statute actually at issue in this case, which clearly prohibits consideration of pa- tentability challenges other than §§ 102 and 103. Still focusing on NTP, the majority transforms that clear holding into a supposed articulation of a general Case: 19-1686 Document: 87 Page: 36 Filed: 07/22/2020

policy inviting resort to all examination requirements wherever there may be “substantial new questions of pa- tentability.” Maj. 18–19. But, in NTP we explained, with- out qualification, that: The scope of reexamination proceedings is limited to “substantial new question[s] of patentability,” 35 U.S.C. § 303(a), which are questions that have not previously been considered by the PTO, Swanson, 540 F.3d at 1379. These new considerations must be based only on “prior art consisting of patents or printed publications.” 35 U.S.C. § 301; see id. § 302. Thus, other challenges to the patentability of orig- inal claims—such as qualification as patentable subject matter under § 101 or satisfaction of the written description and enablement requirements of § 112—may not be raised in reexamination pro- ceedings. In re NTP, Inc., 654 F.3d at 1275–76 (emphasis added). Oddly, the majority views this language as somehow sup- porting its conclusion that proposed substitute claims must be subject to a full examination in the IPR context. I disa- gree. NTP actually supports the opposite conclusion, by reference to the specific reexamination statute at issue and the limitations articulated therein. That is precisely what we must do here. Even if NTP meant to create an exception to the § 101 exclusion it called out, moreover, and intended to apply it to the as yet unenacted AIA, amending a claim in response to prior art raised in a petition, in the manner contemplated by the IPR statutes, does not somehow inject a new question of patentability as to the claim—substan- tial, or otherwise. If the challenged patent claims were in- valid under § 101 prior to amendment, amending them to be narrower is not going to create a “new” question of pa- tentability. At worst, the claims would be invalid just as Case: 19-1686 Document: 87 Page: 37 Filed: 07/22/2020

they were before. At best, the patentee may have resolved the § 101 issue by amendment. 8 Concerns about 35 U.S.C. § 112 fill out much of the re- mainder of the majority’s opinion. See Maj. 19–20. These concerns are also misguided and misplaced. Section 316(d)(3) mandates that substitute claims not add new matter or enlarge the scope of the claims. 35 U.S.C. § 316(d)(3) (“An amendment under this subsection may not enlarge the scope of the claims of the patent or introduce new matter.”). In order to ensure compliance with the stat- ute, the Board must necessarily discern the scope of the claims and evaluate whether the matter claimed is in the specification. This process may look a great deal like the inquiry required by § 112 and, indeed, the Board may choose to use our indefiniteness and written description case law as a guide. That does not, however, transform the Board’s process of deciding whether the claims comply with the statute into a patentability analysis under § 112. Sec- tion 112 is not, moreover, a patentability provision. Like § 120, it appears in Chapter 11 of Title 35, “Application for

8 The parties quibble about whether a narrower or more detailed claim could somehow move from patent eli- gible to patent ineligible under our § 101 case law. See Ap- pellee’s Br. 28–29 (stating, without example, that such a result is possible); Intervenor’s Br. 26–27 (theorizing a claim where the added point of novelty in a substitute claim, beyond the limitations in the issued claims, is a fun- damental business practice); Appellant’s Reply Br. 6–7 (noting that the Director’s hypothetical is farfetched and contingent on the Board first finding the challenged claims invalid). The mental gymnastics necessary to imagine the situations described by the Director and Appellees are suf- ficient for me to conclude that this is not a legitimate con- cern. And it is certainly not one that could not be addressed in District Court. Case: 19-1686 Document: 87 Page: 38 Filed: 07/22/2020

Patent.” Thus, as applied to substitute claims, § 112 may properly be viewed as a “tool” the Board can use in deciding whether the claims comply with the statute. See In re NTP, Inc., 654 F.3d at 1277. Finally, the majority attempts to diminish the signifi- cance of the Aqua Products plurality opinion by implying that its discussion of the overall IPR statutory scheme was directed only to “whether a petitioner challenging the pro- posed substitute claims bears § 316(e)’s burden of proof.” Maj. 20–21. I respond only by noting that the Aqua Prod- ucts plurality opinion was joined by five of the eleven judges participating in that matter, and only one dissent questioned the opinion’s statement of the statutory scheme. See Aqua Prod., Inc., 872 F.3d at 1306–14 (O’Mal- ley, J., joined by Newman, J., Lourie, J., Moore, J., and Wallach, J.). When faced with a question closely related to the one we address today, a majority of the court declined to adopt an interpretation of § 318(a) that gives two sepa- rate operative meanings to the requirement that the Board determine “patentability” in the IPR context. Id. at 1345– 52 (Taranto, J., dissenting, joined in relevant part by Prost, C.J., Chen, J., and Hughes, J.). Given this history, it is clear to me that Aqua Products is highly relevant to our resolution of this case. B My colleagues’ conclusion that, when it comes to sub- stitute claims, anything goes, is also contrary to the policy supporting the IPR system. IPRs are meant to be an effi- cient, cost-effective means for adjudicating patent validity. See H.R. REP. NO. 112–98, pt. 1, at 48 (2011). They are not intended to also serve as a means for full-blown exam- ination. Consistent with this, the legislative history is clear that substitute claims serve to preserve for the pa- tentee the narrower patent right that is merited in view of the art. See Patent Quality Improvement: Post-Grant Op- position: Hearing Before the Subcomm. on Courts, the Case: 19-1686 Document: 87 Page: 39 Filed: 07/22/2020

Internet, and Intellectual Property of the H. Comm. on the Judiciary, 108th Cong. 10 (2004) (statement of PTO Gen- eral Counsel James A. Toupin: “By providing for the possi- bility of amendment of challenged claims, the proposed system would preserve the merited benefits of patent claims better than the win-all or lose-all validity contests in district court.”). The majority opinion opens substitute claims to an ex- amination equivalent to that undertaken during patent prosecution, in an inter partes environment. The major- ity’s reasoning requires, in effect, that the Board consider all manner of prior art (not just the limited categories men- tion in § 311(b)), as well as all other criteria normally ad- dressed by an examiner, to fulfill its § 318(a) obligation prior to issuing new claims. 9 Presumably, a petitioner will now be free to raise any of these issues in response to a patentee’s motion to amend. The already mammoth task of examining claims in the context of an ex parte prosecu- tion will be fully shifted to an inter partes, litigation driven proceeding that is overseen not by an examiner but by an

9 In stark contrast to the majority’s position, the Precedential Opinion Panel recently made clear that it does not view the Board as independently fulfilling an ex- aminational function. See Hunting Titan, Inc. v. Dynaener- getics Europe Gmbh, No. IPR2018-00600, 2020 WL 3669653, at *4–6 (P.T.A.B. July 6, 2020) (holding that the Board should decide proposed substitute claims on grounds other than those raised by a petitioner in only rare circum- stances). Case: 19-1686 Document: 87 Page: 40 Filed: 07/22/2020

Administrative Patent Judge. 10 The inefficiencies of this process are apparent. 11 Accordingly, in my view, the process the majority ap- proves today runs in the face of the efficient resolution an- ticipated by Congress. It also improperly places an examination process in the hands of an administrative judge. IV This case was dead on arrival—there were no live claims remaining in the ’960 patent. I see the dead patent for what it is—a legal nullity incapable of supporting any further proceedings. I would end the case with that reve- lation. The majority, however, views the ’960 patent as an opportunity and takes it. It declares that dead patents can walk, at least as far as needed to die again on the same § 101 sword that killed it two years ago. That sword, how- ever, does not exist in the IPR context. The Board can can- cel claims and find proposed substitute claims

10 Given the majority’s focus on reexamination pro- ceedings, it is worth pointing out that, in those proceed- ings, an examiner, not an Administrative Patent Judge, takes the first pass at determining patentability. See 35 U.S.C. § 305; MPEP § 2253 11 The inefficiency the Majority introduces is also un- necessary. Substitute claims are not unexamined—they are narrower versions of claims that already went through examination, including under § 101. See 37 C.F.R. § 42.121(a)(2); Aqua Prod., 872 F.3d at 1314–15. To the extent any defect exists in proposed substitute claims, they “remain subject to challenge in various future proceedings, including subsequent IPRs, ex parte reexaminations, dis- trict court litigations, or through the Director’s ability to initiate an ex parte reexamination pursuant to 37 C.F.R. § 1.520.” Aqua Prod., 872 F.3d at 1315. Case: 19-1686 Document: 87 Page: 41 Filed: 07/22/2020

unpatentable, certainly. It simply does not have statutory authority to do so based on § 101. Accordingly, I dissent.
