     Before LOURIE, BRYSON, and REYNA, Circuit Judges.
 BRYSON, Circuit Judge.
     Appellant SoftView LLC appeals from a decision of the
 Patent Trial and Appeal Board in two inter partes reexamination proceedings. Based on a prior decision in an inter
 partes review (“IPR”) proceeding, the Board held all claims
 of SoftView’s 
U.S. Patent No. 7,461,353
 (“the ’353 patent”)
 invalid under the estoppel provision set forth in 
37 C.F.R. § 42.73
(d)(3)(i).
      SoftView challenges the Board’s application of section
 42.73(d)(3)(i) on various grounds. First, SoftView contends
 that the PTO improperly interpreted the regulation in a
 manner that gave it broader scope than the common law
 rule of collateral estoppel. Second, SoftView argues that
 the Patent and Trademark Office (“PTO”) lacks statutory
 authority to promulgate a regulation governing the estoppel effect of IPR decisions in subsequent proceedings before
 the PTO. Third, SoftView maintains that the regulation by
 its terms does not apply to claims that have already issued.

 SOFTVIEW LLC v. APPLE INC.                                  3



     We uphold the validity of the regulation and the estoppel standard adopted in the regulation. With respect to the
 scope of the regulation, however, we agree with SoftView
 that the regulation applies to new claims or amended
 claims, but not to previously issued claims.
                               I
     1. The Leahy-Smith America Invents Act (“AIA”), Pub.
 L. No. 112–29, 
125 Stat. 284
 (2011), established the IPR
 process and gave the PTO rulemaking authority to implement it. Specifically, Congress instructed the Director of
 the PTO to prescribe regulations “governing inter partes
 review . . . and the relationship of such review to other proceedings under this title.” 
35 U.S.C. § 316
(a)(4).
     Pursuant to its authority under section 316(a)(4), the
 PTO promulgated rules governing the procedures to be followed in IPR proceedings. Among those rules was the rule
 codified at 
37 C.F.R. § 42.73
(d)(3), which addressed the operation of estoppel principles in patent office proceedings.
      That rule prohibits a patent owner from “taking action
 inconsistent with the adverse judgment” in various proceedings, including IPR proceedings. As the PTO explained when the regulation was issued, section 42.73(d)(3)
 applies to judgments in “derivation proceedings, inter
 partes review, post-grant review, and covered business
 method review.” Rules of Practice for Trials Before the Patent Trial and Appeal Board and Judicial Review of Patent
 Trial and Appeal Board Decisions (“Rules of Practice II”),
 
77 Fed. Reg. 48612
, 48649 (Aug. 14, 2012). In particular,
 the regulation prohibits a patent owner from “obtaining in
 any patent: (i) A claim that is not patentably distinct from
 a finally refused or canceled claim.”
     2. The ’353 patent is directed to displaying internet
 content on mobile devices. Various phone manufacturers
 have challenged the validity of the ’353 patent in proceedings before the PTO. In 2011, Apple filed a request for inter
Case: 23-1005     Document: 73      Page: 4    Filed: 07/26/2024

 partes reexamination of the ’353 patent. Proceeding No.
 95/000,634. Over the next two years, Apple filed a separate
 request for ex parte reexamination of the ’353 patent, proceeding No. 90/009,994, and Motorola also filed a request
 for inter partes reexamination of the ’353 patent, proceeding No. 95/002,132. On October 12, 2012, Kyocera filed a
 petition for inter partes review of 18 of the 319 claims of the
 ’353 patent, proceeding No. IPR2013-00007. The Board
 stayed all of the reexamination proceedings pending the
 outcome of the IPR proceeding.
     On March 27, 2014, the Board issued a final written
 decision in the IPR proceeding, finding each of the 18 challenged claims of the ’353 patent unpatentable. This court
 summarily affirmed. SoftView LLC v. Kyocera Corp., 
592 F. App’x 947
 (Fed. Cir. 2015). The IPR certificate issued on
 January 12, 2016, canceling the challenged claims.
     3. The stay of the ex parte and inter partes reexamination proceedings challenging the remaining claims of the
 ’353 patent was lifted on November 27, 2015. In ex parte
 reexamination No. 90/009,994, SoftView amended various
 claims of the patent, which were then deemed patentable
 over the prior art. There are 107 such amended claims. 1
     To the extent they differ more than trivially from the
 canceled claims, the amended claims merely combine limitations from multiple canceled claims. For example, original claims 1, 118, and 138 (which depends from claim 118)



     1   The amended claims are claims 5, 23–27, 60–61,
 122, 137, 140–41, 147, 156, 174–77, 238–42, 248, 259, and
 274–77, as well as the claims that depend from those directly amended, which are claims 9, 12–14, 16–17, 19–21,
 71–83, 85, 86, 88–111, 126, 129, 130, 132, 134, 135, 162–
 64, 166–67, 215, 226–36, 245–47, 251, 265, 266, 268, and
 270–71. This list includes some claims that are not on appeal.

 were all found invalid in the IPR. Amended claim 5 combines the device of claim 1 together with the method of
 claim 118/138, with only immaterial differences in phrasing. Compare ’353 patent, Ex Parte Reexamination Certificate at col. 1, line 31, to col. 2, line 10 (amended claim 5)
 with ’353 patent at col. 22, ll.15–43 (canceled claim 1) and
 
id.
 at col. 34, ll. 6–19 (canceled claim 138).
     In the inter partes reexaminations, the examiner found
 the overwhelming majority of claims unpatentable over the
 prior art under 
35 U.S.C. § 103
. On appeal, the Board reversed the examiner’s obviousness rejections on the ground
 that there was “insufficient articulated reasoning to support the Examiner’s final conclusion that the claims would
 have been obvious to one of ordinary skill in the art at the
 time of Appellant’s invention.” J.A. 69. The Board, however, entered a new ground of rejection as to all pending
 claims based on 
37 C.F.R. § 42.73
(d)(3)(i). The Board applied that regulation both to the “amended claims” and to
 the claims that had already issued.
     Going claim by claim, the Board found that each claim
 was either essentially the same as a canceled claim or
 merely a combination of limitations that had previously
 been invalidated on obviousness grounds in the IPR.
 Where the Board found the latter, it reasoned that the limitations in combination “merely perform as they did in each
 sub-combination.” See, e.g., J.A. 90. For that reason, the
 Board held that the claims were not “patentably distinct”
 from those that had been invalidated in the IPR proceeding
 and were therefore invalid under section 42.73(d)(3)(i) of
 the PTO’s regulations.
                               II
     SoftView first challenges the Board’s interpretation of
 the term “patentably distinct” that is used in section
 42.73(d)(3)(i). SoftView contends that the regulation was
 intended to codify the common law doctrine of collateral estoppel and that the Board improperly interpreted the
Case: 23-1005     Document: 73     Page: 6    Filed: 07/26/2024




 6                                  SOFTVIEW LLC v. APPLE INC.




 regulation as giving broader preclusive effect to the decision in the IPR proceeding involving the ’353 patent claims
 than would have been the case if the Board had applied
 common law collateral estoppel principles.
      The Board gave the term “patentably distinct” in section 42.73(d)(3)(i) the same meaning as that term is given
 in obviousness-type double patenting cases and in interference proceedings. See, e.g., Takeda Pharm. Co. v. Doll, 
561 F.3d 1372, 1375
 (Fed. Cir. 2009) (addressing whether
 claims are “patentably distinct” for purposes of double patenting rejection); In re Deckler, 
977 F.2d 1449, 1452
 (Fed.
 Cir. 1992) (precluding an applicant from obtaining “claims
 for inventions that are patentably indistinct from those in
 an interference that the applicant had lost”). Applying the
 same definition of the term “patentably distinct,” the Board
 interpreted section 42.73(d)(3)(i) to prohibit a patent owner
 from obtaining a claim that would be anticipated by, or obvious in light of, a previously canceled claim. See J.A. 17,
 77 (citing Eli Lilly & Co. v. Barr Lab’ys, Inc., 
251 F.3d 955
,
 968 (Fed. Cir. 2001)).
     Because the term “patentably distinct” has a specialized meaning in patent law, it can be presumed that the
 PTO intended to adopt that meaning when it promulgated
 the regulation. Identical words used in a given field of law
 typically carry the same meaning. See Henson v. Santander Consumer USA Inc., 
582 U.S. 79, 85
 (2017). Thus, absent strong evidence to the contrary, the PTO’s use of the
 term “patentably distinct” in section 42.73(d)(3)(i) should
 be read to invoke the term’s established meaning in the
 double patenting and interference contexts. That is particularly so because the term “patentably distinct” serves a
 similar purpose in all three settings: to prohibit a patentee
 from exploiting patent claims that are not materially distinguishable from claims that have either expired or been
 invalidated in prior proceedings.
Case: 23-1005    Document: 73      Page: 7    Filed: 07/26/2024




 SOFTVIEW LLC v. APPLE INC.                                 7



     In its first argument to the contrary, SoftView contends
 that the term “not patentably distinct” in section
 42.73(d)(3)(i) should be interpreted to mean “substantially
 the same.” SoftView argues that the requirement that a
 claim be “substantially the same” as the previously canceled claim was meant to adopt the principles of common
 law collateral estoppel.
     In support of that argument, SoftView points out that
 the initially proposed version of section 42.73(d)(3)(i) provided that estoppel based on a prior adverse ruling in an
 IPR proceeding would apply to “[a] claim to substantially
 the same invention as the finally refused or cancelled
 claim.” Rules of Practice for Trials Before the Patent Trial
 and Appeal Board and Judicial Review of Patent Trial and
 Appeal Board Decisions (“Rules of Practice I”), 
77 Fed. Reg. 6879
, 6913 (Feb. 9, 2012). In the final version of the regulation, the PTO revised that language to read “[a] claim
 that is not ‘patentably distinct’ from a finally refused or
 canceled claim.” Although the PTO did not explain why it
 made the change from the initially proposed version of the
 regulation, it appears likely that the change was made for
 clarification, as the term “not patentably distinct” has a
 precise meaning in patent law, whereas “substantially the
 same” does not.
     There is also support outside the context of section
 42.73(d)(3) for the argument that “not patentably distinct”
 means “substantially the same.” See SimpleAir, Inc. v.
 Google LLC, 
884 F.3d 1160, 1167
 (Fed. Cir. 2018) (holding,
 in the context of claim preclusion, that “claims which are
 patentably indistinct are essentially the same”). In fact,
 elsewhere in the PTO’s regulations, the term “substantially
 the same” is defined to mean “patentably indistinct.” 
37 C.F.R. § 42.401
.
     While SoftView is correct that the terms “not patentably distinct” and “substantially the same” are equivalent,
 that does not advance SoftView’s argument that the Board
Case: 23-1005     Document: 73     Page: 8    Filed: 07/26/2024




 8                                  SOFTVIEW LLC v. APPLE INC.




 misapplied section 42.73(d)(3)(i). The Board found that the
 regulation barred SoftView from obtaining claims that
 were not patentably distinct from those canceled in the IPR
 proceeding; the Board plainly would have reached the same
 conclusion if it had used the “substantially the same” test
 for which SoftView has advocated, as that test is defined to
 invoke the “not patentably distinct” standard.
     SoftView’s second argument is that section
 42.73(d)(3)(i) should be construed as adopting common law
 principles of collateral estoppel. SoftView bases that argument principally on a response by the PTO to comments on
 the proposed version of section 42.73(d)(3) during the
 promulgation process. In response to a complaint that the
 proposed rule was at odds with various legal doctrines, the
 PTO stated that the regulation was “consistent with the
 AIA, other statutory provisions, the common law related to
 estoppel, and the common law related to the recapture
 rule.” Rules of Practice II, 77 Fed. Reg. at 48649.
     SoftView’s position is unpersuasive. The Board’s analysis, which involved comparing the claims before it with
 the previously canceled claims, paralleled the analysis under common law collateral estoppel, which would have involved comparing the claims before the Board with the
 prior art. In holding that the claims before it were not materially different from the canceled claims in any way that
 would affect patentability, the Board’s approach merely
 considered whether the resolution of an issue in a previous
 case bars the relitigation of that issue in a subsequent case.
 That is the same question addressed under the common
 law rule. See Regents of the University of Minnesota v. LSI
 Corp., 
926 F.3d 1327
, 1345–46 n.5 (Fed. Cir. 2019) (“To the
 extent the estoppel provisions in 
37 C.F.R. § 42.73
(d)(3)
 prevent a patent owner from obtaining a patent on claims
 that are patentably indistinct from cancelled claims in an
 IPR proceeding, that result is no different than what is
 mandated under traditional principles of res judicata and
 collateral estoppel.”).

 SOFTVIEW LLC v. APPLE INC.                                 9



      SoftView’s core complaint is that the Board applied estoppel based on the IPR decision canceling claims from the
 ’353 patent rather than comparing the claims before it to
 the prior art. As to that issue, however, the plain text of
 the regulation unambiguously supports the Board’s action.
 Section 42.73(d)(3)(i) goes beyond the common law rule by
 calling for a comparison between the claims an applicant is
 “obtaining” and the “finally refused or canceled claim.”
 Whether the Board’s action was lawful thus depends on
 whether the PTO had statutory authority to issue the regulation, an issue that we address below.
                              III
      Because section 42.73(d)(3) renders unpatentable a
 category of claims that would not necessarily be unpatentable on obviousness grounds over the prior art, SoftView
 argues that the PTO lacked authority to promulgate it.
 Under the legal framework in place absent the regulation,
 claims are judged for obviousness over the prior art—not
 over previously canceled claims, as allowed by the regulation. SoftView contends that the PTO has statutory authority to issue regulations on procedural matters, but not
 on substantive issues of patent law, such as the estoppel
 effect of PTO decisions. The appellees and the intervenor,
 however, point to 
35 U.S.C. § 316
(a)(4), which authorizes
 the Director to prescribe regulations “establishing and governing inter partes review under this chapter and the relationship of such review to other proceedings under this
 title.” We reject SoftView’s argument and hold that section
 42.73(d)(3) of the PTO’s regulations was lawfully promulgated pursuant to the agency’s rulemaking authority under
 section 316(a)(4) of the Patent Act.
    This court has held that 
35 U.S.C. § 2
(b)(2)(A), which
 authorizes the PTO to issue regulations that “govern the
 conduct of proceedings in the Office,” does not authorize the
 PTO to issue “substantive” rules. See Cooper Techs. Co. v.
 Dudas, 
536 F.3d 1330
, 1335–36 (Fed. Cir. 2008). But
Case: 23-1005    Document: 73     Page: 10    Filed: 07/26/2024




 10                                SOFTVIEW LLC v. APPLE INC.




 section 316(a)(4) refers broadly to regulations “governing
 inter partes review and the relationship of such review to
 other proceedings” before the PTO, and it provides a separate source of rulemaking authority for the PTO to issue
 such regulations. 2
     Thus, contrary to SoftView’s contention, section
 316(a)(4) is not limited to authorizing the PTO to issue procedural rules. The Supreme Court made that point explicitly in Cuozzo Speed Techs., LLC v. Lee, 
579 U.S. 261
 (2016), in which the Court distinguished section 316(a)(4)
 from section 2(b)(2)(A), which this court had interpreted as
 being “limited to procedural rules.” 3 
Id. at 277
. The Court
 held the caselaw interpreting section 2(b) inapplicable because section 316(a)(4) is not limited to “proceedings,” and




      2   To be sure, the PTO’s authority under Section
 316(a)(4) is not unbounded. See Ernst & Ernst v. Hochfelder, 
425 U.S. 185
, 213–14 (1976). Section 316(a)(4) does
 not grant the PTO the authority to legislate new patent
 laws, but rather charges it with prescribing regulations
 governing IPR proceedings. See Oral Arg. 26:00–50 (appellee conceding that the PTO does not have “unfettered” authority under section 316(a)(4)). We do not define the exact
 limits of this statutory provision today but narrowly determine that it authorized the PTO to promulgate section
 42.73(d)(3)(i). The task of defining the bounds of section
 316(a)(4) is for a later date and to be decided on a record
 with briefing more dedicated to that issue and in consideration of the Supreme Court’s recent ruling in Loper Bright
 Enters. v. Raimondo, Nos. 22-451, 22-1219, (U.S. June 28,
 2024).
      3   The Court questioned whether section 2(b)(2)(A) itself should be limited to procedural rules, noting that the
 statute “does not clearly contain the Circuit’s claimed limitation.” Cuozzo, 
579 U.S. at 277

 instead applies “broadly to regulations ‘establishing and
 governing inter partes review.’” 
Id.
     Section 42.73(d)(3), which prohibits “taking action inconsistent with [an] adverse judgment,” is clearly directed
 to “governing inter partes review” and the “relationship of
 such review to other proceedings” before the PTO. As the
 PTO explained when it adopted the set of regulations to
 which section 42.73(d)(3) belongs, one of the purposes of
 those regulations is to “ensure the integrity of the trial procedures.” Rules of Practice II, 77 Fed. Reg. at 48612. Preventing a patent owner or applicant from acting
 inconsistently with the outcome of an IPR proceeding ensures that the decisions in those proceedings have practical
 effect. Preventing such inconsistent action is therefore
 closely tied to the statutory grant of authority to issue regulations “governing inter partes review.”
     Section 42.73(d)(3)(i) provides a specific example of
 such an inconsistent action. It would be inconsistent with
 the decision in an IPR if, for example, a patent owner obtained claims not patentably distinct from those canceled
 in the IPR by way of a continuation or reissue application.
 Section 42.73(d)(3)(i) thereby serves the same purpose as
 the more general provision in section 42.73(d)(3): ensuring
 the integrity of the proceedings before the PTO by preventing actions that would undermine the outcomes of those
 proceedings. As such, the estoppel provision in section
 42.73(d)(3)(i) falls within the rulemaking authority
 granted to the PTO in section 316(a)(4) of the Patent Act.
                               IV
     Although we agree that the PTO was authorized to
 promulgate section 42.73(d)(3)(i), we disagree with the
 Board’s application of that regulation to previously issued
 claims. By its terms, the regulation applies to “obtaining”
 a claim—not maintaining an existing claim. For that reason, we vacate the Board’s decision as to the “issued claims”

 on appeal but affirm its application of the regulation to the
 “amended claims.” 4
                              A
     Two other panels of the Board have previously held
 that section 42.73(d)(3)(i) does not apply to issued claims.
 In Apple Inc. v. Contentguard Holdings, Inc., the Board explained that
      comments accompanying the rule suggest that it is intended to preclude recapturing in another USPTO proceeding—e.g., prosecuting a continuing or reissue
      application—subject matter that was lost in an AIA
      proceeding. Thus, this rule does not preclude Patent
      Owner from defending the patentability of the challenged claims.

 Corp., IPR2017-00428, at *8 (P.T.A.B Jun. 22, 2018).
     The Board in the present case found the decisions in
 Apple v. Contentguard and General Electric v. United Technologies distinguishable because those decisions were in
 IPR cases, whereas the present case concerns an inter
 partes reexamination. Unlike IPR proceedings, the Board
 reasoned, inter partes reexaminations are “examinationlike” proceedings, warranting the application of a different

     We agree with the Board’s conclusions in Apple v. Contentguard and General Electric v. United Technologies, and
 we hold that the reasoning in those cases applies to both
 IPRs and inter partes reexaminations. For purposes of section 42.73(d)(3)(i), we see no meaningful distinction between maintaining a non-distinct claim in an IPR
 proceeding and maintaining such a claim in an inter partes




     5    In support of that distinction, the Board in this case
 cited Ex parte Nelson, 
2020 WL 8186425
 (P.T.A.B. Dec. 31,
 2020), in which the patent owner argued, in an inter partes
 reexamination, that “obtaining” did not include maintaining claims. But the Board in Nelson did not address that
 argument. Instead, the Board rejected the patent owner’s
 position because the provision in section 42.73(d)(3) that
 prohibits a patent owner from taking “action inconsistent
 with the adverse judgment” separately estopped the patent
 owner from arguing issues decided in the earlier IPR. Nelson ultimately held that estoppel applied, “but only to the
 extent that Appellant’s arguments [were] inconsistent with
 the prior adverse judgment.” 
2020 WL 8186425
, at *7; see
 also 
id. at *5
 (“Appellant’s narrow focus on the single example provided in sub-section (i) ignores the broader language in § 42.73(d)(3),” which “is not limited to . . .
 obtaining a claim that is not patentably distinct from a finally canceled claim.” (cleaned up)). The Board in Nelson
 did not hold, as the Board panel in this case believed, that
 section 42.73(d)(3)(i) has the effect of prohibiting a patent
 owner from maintaining non-distinct claims in inter partes
 reexamination proceedings.

 reexamination, and we note that the regulation does not
 draw any such distinction.
      Drawing a distinction between obtaining a new claim
 and maintaining a previously issued claim makes sense. It
 is reasonable to characterize “obtaining” a new claim that
 is not patentably distinct from a finally refused or canceled
 claim” as an “action inconsistent with the adverse judgment” under 
37 C.F.R. § 42.73
(d)(3), because such an action can fairly be viewed as an effort to circumvent the
 prior adverse judgment. By contrast, seeking to maintain
 an already issued claim cannot be viewed as circumventing
 a subsequent decision on related claims. We therefore conclude that, as the plain language of the rule suggests, the
 PTO elected not to include the latter class of claims within
 the scope of the estoppel rule in section 42.73(d)(3)(i). Accordingly, we vacate the Board’s decision as to the issued
 claims that the Board invalidated based on estoppel.
                              B
     SoftView does not challenge the Board’s holding that
 claims amended during an ex parte reexamination are “obtained” for purposes of section 42.73(d)(3)(i). Instead,
 SoftView argues that the amended claims at issue are patentably distinct from the claims canceled in the IPR proceeding. Specifically, SoftView challenges the Board’s
 general methodology of considering whether two obvious
 limitations, when combined, perform differently such that
 their combination renders the resulting claim nonobvious.
 SoftView further argues that errors in claim construction
 infected the Board’s analysis of various claims. We affirm
 the Board’s conclusions on these issues.
     The question whether claims are patentably distinct focuses on “the differences in subject matter between the
 claims.” Amgen Inc. v. F. Hoffman-La Roche Ltd, 
580 F.3d 1340, 1361
 (Fed. Cir. 2009). That step “is analogous to an
 obviousness analysis under 
35 U.S.C. § 103
.” Eli Lilly &
 Co. v. Teva Parenteral Medicines, Inc., 
689 F.3d 1368
, 1377

 (Fed. Cir. 2012). In general, the combination of known elements may be nonobvious if the invention as a whole “is
 more than the predictable use of prior art elements according to their established functions.” KSR Int’l Co. v. Teleflex
 Inc., 
550 U.S. 398, 417
 (2007). The Board’s “patentably distinct” analysis merely applied KSR’s instruction to the canceled claims rather than to prior art references. The Board
 evaluated whether the combination of the canceled claim
 limitations—all of which are individually in the prior art—
 made them anything more than the obvious sum of their
 parts. The Board concluded that it did not.
     There are 107 amended claims at issue in this case.
 SoftView does not raise specific arguments with respect to
 whether particular amended claims are patentably distinct
 from the canceled claims. Our review is therefore limited
 to the Board’s general methodology, which we uphold. We
 do not address whether that methodology was correctly applied to specific claims. We also do not address whether
 the various claim constructions SoftView challenges were
 improper. Even if we were to agree with SoftView’s positions, SoftView’s failure to tie its claim construction arguments to specific claims prevents us from determining
 whether the Board’s constructions “could impact the conclusion.” See State Contracting & Eng’g Corp. v. Condotte
 Am., Inc., 
346 F.3d 1057
, 1068 (Fed. Cir. 2003). We therefore affirm the application of section 42.73(d)(3)(i) to the
 amended claims.
                               V
      We have considered SoftView’s remaining arguments
 and find them unpersuasive. For the reasons stated, we
 affirm the Board’s application of section 42.73(d)(3)(i) to
 the amended claims, but we vacate and remand for further
 consideration of the application of the regulation to issued
