     Before NEWMAN, LINN, and CHEN, Circuit Judges.
 LINN, Circuit Judge.
     SawStop Holding LLC (“Sawstop”) appeals from the
 District Court’s grant of summary judgment in favor of the
 United States Patent and Trademark Office (“PTO”) in
 each of two suits filed by Sawstop to challenge the denial
 of patent term adjustments (“PTAs”) for Sawstop’s U.S. Pa-
 tent Nos. 9,522,476 (“’476 patent”) and 9,927,796 (“’796 pa-
 tent”). For the reasons discussed infra, we affirm.
                               I
     To compensate for certain delays during prosecution of
 patents, Congress added provisions for patent term adjust-
 ment in the American Inventors Protection Act of 1999.
 The Act directs the PTO to grant patent term adjustments
 to offset three categories of prosecution delay set forth in
 35 U.S.C. § 154(b)(1)(A), (B), and (C). Subsection (A) delay
 accrues when the PTO fails in certain specified ways to
 timely respond to the applicant. Subsection (B) delay ac-
 crues when the PTO fails to issue a patent within a certain
 time from filing. Neither of those subsections is at issue in
 this case. At issue in this consolidated appeal is subsection
 (C) delay, which is codified in 35 U.S.C. § 154(b)(1)(C) and
 accrues for certain delays associated with appellate review.
 That provision reads, inter alia:
     Subject to the limitations under paragraph (2), if
     the issue of an original patent is delayed due to . . .
         (iii) appellate review by the Patent Trial
         and Appeal Board or by a Federal court in
Case: 21-1537    Document: 50     Page: 3    Filed: 09/14/2022

 SAWSTOP HOLDING LLC   v. VIDAL                            3

        a case in which the patent was [1] issued
        under a decision in the review [2] reversing
        an adverse determination of patentability,
    the term of the patent shall be extended 1 day for
    each day of the pendency of the proceeding, order,
    or review, as the case may be.
 35 U.S.C. § 154(b)(1)(C) (emphasis added). The meanings
 of the two italicized phrases noted above are at the center
 of these appeals.
     The patents at issue in these cases are both directed to
 power saws with a safety feature that instantly stops the
 saw blade upon contact with flesh. Issuance of these pa-
 tents was delayed by appeals before allowance. For both
 patents, Sawstop requested PTA for (C) delay under the
 specific facts surrounding the appeals pursued in each
 case.
     With respect to the application that led to the issuance
 of the ’476 patent, claim 11 was finally rejected by the ex-
 aminer as being obvious over Figures 7–9 of Lokey, which
 show a table saw with a rubber block engaging to stop
 blade rotation, and Figures 1–5 of Lokey, which show a
 handheld saw with a pivoting cam brake, in combination
 with the disclosure of Fergle, which teaches an explosive
 actuator. Sawstop appealed that rejection to the Patent
 Trial and Appeal Board (“Board”).
      The Board held that “the examiner [did] not make suf-
 ficient findings regarding modifying the structure of
 Lokey’s embodiment of Figures 7–9 to incorporate cam
 brake members 24 of Lokey’s embodiment of Figures 1–5,”
 and thus concluded that “the Examiner [had] not made the
 initial factual findings required to demonstrate a prima fa-
 cie case of obviousness of claim 11.” J.A. 1826. Neverthe-
 less, the Board held that Lokey Figures 7–9 were sufficient
 in themselves to teach the pivotable component limitation
 in claim 11 and render claim 11 obvious in combination

 with Fergle.  It thus “AFFIRMED” the rejection of
 claim 11, J.A. 1829, on “a NEW GROUND OF
 REJECTION,” J.A. 1827.
     On remand, Sawstop reopened prosecution to address
 the new ground of rejection. It filed several amendments
 and a request for continued examination (“RCE”). The ex-
 aminer eventually allowed claim 11, which issued as
 claim 1 of the ’476 patent. The PTO made no adjustment
 to the term of the patent for the time spent on the appeal.
 Sawstop sought redetermination of that decision. The PTO
 denied Sawstop’s request. In doing so, the PTO cited the
 language of 35 U.S.C. § 154(b)(1)(C)(iii) and held that “the
 claim was not issued under a decision in the review revers-
 ing an adverse determination of patentability” because
 “the claim remain[ed] under rejection after the Board deci-
 sion” and “the patent only issue[d] after further prosecu-
 tion” and amendment. J.A. 2246–47.
     Thereafter, Sawstop filed a complaint in the District
 Court for the Eastern District of Virginia challenging the
 PTO’s interpretation of 35 U.S.C. § 154(b)(1)(C)(iii) and the
 denial of PTA under the Administrative Procedure Act
 (“APA”). Sawstop and the PTO filed cross motions for sum-
 mary judgment. The District Court denied Sawstop’s mo-
 tion and granted the government’s motion, holding that
 because claim 11 was subject to a new ground of rejection
 on appeal, the ’476 patent application was not “issued un-
 der a decision in the review reversing an adverse determi-
 nation of patentability,” and thus was not eligible for PTA
 under § 154(b)(1)(C)(iii). Sawstop Holding LLC v. Iancu,
 496 F. Supp. 3d 944, 950 (E.D. Va. 2020) (“’476 Decision”).
     With respect to the ’796 patent, prosecution culminated
 in the examiner finally rejecting independent claim 1 on
 two bases—anticipation and provisional non-statutory ob-
 viousness-type double patenting (“double patenting”)—and
 finally rejecting dependent claim 2 for anticipation. Saw-
 stop appealed all three rejections to the Board. The Board

 affirmed both rejections of claim 1, but reversed the antic-
 ipation rejection of claim 2, rendering it patentable.
      Sawstop then filed a complaint in the District Court for
 the District of Columbia challenging only the Board’s an-
 ticipation rejection of claim 1. The complaint did not ad-
 dress the provisional double patenting rejection.
 Ultimately, the District Court reversed the anticipation re-
 jection of claim 1. In doing so, it had no reason to and did
 not opine on the provisional double patenting rejection. On
 remand, the Board noted the outstanding provisional dou-
 ble patenting rejection, and gave Sawstop two options for
 allowance: Sawstop could file a terminal disclaimer or can-
 cel claim 1 and rewrite claim 2 as an independent claim.
 J.A. 877. Sawstop chose the latter.
     The Board thereafter issued a notice of allowance of
 claim 2 and other claims dependent therefrom.
 J.A. 887–88. Sawstop nevertheless filed an RCE and con-
 tinued prosecution through several additional amend-
 ments of the claims, drawings, and specifications.
 Eventually, the PTO issued a notice of allowance of the ’796
 patent.     The PTO granted PTA under 35 U.S.C.
 § 154(b)(1)(C)(iii) for the delay incurred in the successful
 reversal of the rejection of claim 2 at the Board. But the
 PTO denied any additional PTA for the delay caused by the
 appeal of claim 1 to the District Court.
     Like it did for the ’476 patent, Sawstop filed a com-
 plaint in the Eastern District of Virginia challenging that
 denial. The District Court entertained cross motions for
 summary judgment, ruling in favor of the PTO. It held that
 the ’796 patent was not entitled to PTA for Sawstop’s ap-
 peal to the District Court for the District of Columbia be-
 cause the appeal did not “revers[e] an adverse
 determination of patentability” as required by 35 U.S.C.
 § 154(b)(1)(C)(iii), as claim 1 remained subject to the out-
 standing provisional double patenting rejection and was
 thus unpatentable both before and after the appeal.

 WL 2021122, at *6–7 (E.D. Va. May 20, 2021) (“’796 Deci-
 sion”). The District Court also held that because claim 1
 was eventually cancelled and thus did not issue in the pa-
 tent, the ’796 patent did not “issue under” an adverse de-
 termination of patentability as that phrase is used in 35
 U.S.C. § 154(b)(1)(C)(iii) and was not eligible for additional
 PTA for that independent reason. Id. at *8.

 cases. We have jurisdiction over final decisions of the Dis-
 trict Court in these patent cases under 28 U.S.C. §§ 1291

 pels affirmance.
                               III
      In considering the meaning of the phrases at issue in
 35 U.S.C. § 154(b)(1)(C)(iii), we begin by reference to the
 plain language of the statute itself. United States v. Hohri,
 482 U.S. 64, 69 (1987). We recently held that the most nat-
 ural meaning of the words “appellate review by the Patent
 Trial and Appeal Board or by a Federal court in a case in
 which the patent was issued under a decision in the review
 reversing an adverse determination of patentability,” when
 applied to an examiner’s unpatentability ruling, requires
 that “the patent issue under a Board decision that reversed
 the examiner’s unpatentability ruling or under a court de-
 cision that reversed a Board unpatentability ruling in the
 matter.” Chudik, 987 F.3d at 1039–40. A “reversal” typi-
 cally means the undoing by an appellate tribunal of a rul-
 ing under review. See id. at 1040. “Type C adjustments
 are for delays that are . . . due to . . . successful appeals.”
 Supernus Pharms., Inc. v. Iancu, 913 F.3d 1351, 1353 (Fed.
 Cir. 2019).
      Here, the District Court held that, consistent with our
 past statutory construction of the (C) delay provision, the
 “unambiguous language imposes two requirements: that
 an adverse determination of patentability be reversed, and
 that the application reviewed in that appeal issue as a pa-
 tent as a result of that reversal.” ’796 Decision, 2021 WL
 2021122, at *5; ’476 Decision, 496 F. Supp. 3d at 948. The
 District Court also concluded that the PTO did not demon-
 strate clear error in judgment in denying the requested
 PTA under 35 U.S.C. § 154(b)(1)(C)(iii) for the ’476 and ’796
 patents as neither patent met either requirement under
 the statute. We find no ambiguity in the language of the
 statute and agree with the conclusions reached by the Dis-
 trict Court for the reasons more fully set forth infra.

                              IV
     With respect to the ’476 patent, Sawstop contends that
 any examiner rejection overturned on appeal, as was the
 examiner’s rejection of claim 11 in this case, qualifies as “a
 reversal of a determination of patentability,” regardless of
 any new grounds of rejection issued by the Board. Sawstop
 argues that the PTO and the District Court improperly in-
 terpreted the statutory expression “reverses an adverse de-
 termination of patentability” to add a new requirement
 that a decision in the review reversing an adverse determi-
 nation of patentability must not subject the claims at issue
 to a new rejection. According to Sawstop, the PTO reading
 finds no support in the statutory text nor serves the under-
 lying purpose of compensating the applicant for appellate
 delays that are not the applicant’s fault.
     The PTO counters by arguing that there was “no rever-
 sal of an adverse patentability determination” because
 claim 11 was unpatentable before and after the Board’s re-
 view in the appeal. According to the PTO, the Board’s set-
 ting aside of the rationale of the examiner’s obviousness
 rejection is irrelevant because it entered new reasoning to
 sustain that same rejection. It also asserts that because
 the Board maintained the unpatentability of claim 11, the
 ’476 patent could not have “issued under” the Board’s deci-
 sion.
     We do not find Sawstop’s argument persuasive. While
 there is no dispute that the Board cast aside the examiner’s
 basis for rejecting claim 11, the Board in the same review
 found claim 11 unpatentable, albeit for a different reason.
 The adverse determination of unpatentability remained
 before and after the appeal to the Board. The appeal thus
 resulted in no substantive change in the patentability of
 claim 11. Such a substantive change is required by the lan-
 guage of the statute itself: the reversal of a “determination
 of patentability” requires a determination that the claim in
 question is substantively allowable, not just free of a

 particular rejection. See Mayo Found. for Med. Educ. &
 Rsch. v. Iancu, 938 F.3d 1343, 1345 (Fed. Cir. 2019) (noting
 that Type C delay “provides PTA for each day the applica-
 tion is pending in . . . a successful appeal to the Patent Trial
 and Appeal Board . . . or a federal court” (emphasis added));
 Supernus, 913 F.3d at 1353 (“Type C adjustments are for
 delays that are . . . due to successful appeals.” (emphasis
 added) (citing 35 U.S.C. § 154(b)(1)(C)(iii))). We reject Saw-
 stop’s attempt to rewrite the statutory text to mandate
 PTA over reversal of a mere “rejection” or “basis for un-
 patentability.” Here, the appeal of the determination of pa-
 tentability of claim 11 was not “successful” as it was not
 “reversed.” The PTO faithfully applied the statutory text
 and did not improperly add a new requirement for eligibil-
 ity for (C) delay.
     The District Court also granted summary judgment on
 an independent basis: that claim 11 of the ’476 patent did
 not “issue under a decision in the review” because after the
 appeal, the claim was subject to a year of additional sub-
 stantive prosecution and amendments to address the
 Board’s new ground of rejection. As can be appreciated
 from the following side-by-side comparison, the claim as is-
 sued was not the same as the claim “under a decision in the
 review.”

 10                             SAWSTOP HOLDING LLC   v. VIDAL

     Sawstop challenges the District Court’s reasoning, ar-
 guing that the claim would not have issued but-for the suc-
 cessful appeal, and thus the “patent was issued under a
 decision in the review.” Again, we disagree. Under Saw-
 stop’s reading, the (C) delay provision could apply when an
 adverse determination of patentability is overcome on ap-
 peal, regardless of substantive amendments made after the
 appeal to secure allowance. This interpretation effectively
 reads out the phrase “in which the patent was issued under
 a decision in the review,” and thus cannot be sustained.
 See Hibbs v. Winn, 542 U.S. 88, 101 (2004) (“A statute
 should be construed so that effect is given to all its provi-
 sions, so that no part will be inoperative or superfluous,
 void or insignificant.”) (quoting 2A N. Singer, Statutes and
Case: 21-1537    Document: 50      Page: 11     Filed: 09/14/2022

 SAWSTOP HOLDING LLC   v. VIDAL                              11

 Statutory Construction § 46.06, pp. 181–86 (rev. 6th ed.
 2000).
      The plain language of “issued under a decision in the
 review” means that at least one claim must “issue[] under”
 the mandate of the appellate decision. At a minimum, this
 means that at least one claim that “issued” must have been
 analyzed by the Board or District Court that issued the “de-
 cision in the review.” The statutory requirement is not met
 if the claim that ultimately issues differs substantively
 from the claim under review.
     Because claim 11 of the ’476 patent application was
 subject to an adverse determination of patentability both
 before and after the appeal, and because the claim issued
 only after significant substantive post-appeal prosecution
 and amendment, we affirm the District Court’s determina-
 tion that the ’476 patent did not “issue[] under a decision
 in the review reversing an adverse determination of pa-
 tentability” as that expression is used in 35 U.S.C.
 § 154(b)(1)(C)(iii).
                               V
     The plain language of the (C) delay provision also com-
 pels affirmance as to claim 1 of the ’796 patent.
      Sawstop argues that the statute only requires the re-
 versal of “an adverse determination of patentability” and
 the PTO’s interpretation improperly replaces the statutory
 “an” with a requirement that “all” rejections of a particular
 claim be reversed. Sawstop’s argument again confuses spe-
 cific rejections with the determination of patentability. As
 noted supra, the singular reversal referenced in the statute
 is the determination of patentability of the claim under ap-
 pellate review, not a basis for a rejection or number of re-
 jections.
     We also reject Sawstop’s contention that the PTO’s in-
 terpretation of 35 U.S.C. § 154(b)(1)(C)(iii) fails to give ef-
 fect to the purpose of the statute. According to Sawstop,
Case: 21-1537    Document: 50      Page: 12     Filed: 09/14/2022

 12                             SAWSTOP HOLDING LLC    v. VIDAL

 the purpose of the statute is to compensate applicants for
 certain reductions in patent term that are not the fault of
 the applicant. Such a broad reading overlooks the plain
 language of the statute, which is not nearly as sweeping as
 Sawstop contends. Sawstop provides no basis to support
 its contention that (C) delay was intended to categorically
 compensate applicants for all appellate delays that were
 not the applicant’s fault. As in Chudik, we do not find Saw-
 stop’s policy rationale a convincing reason to depart from
 the plain meaning of the statute. See Chudik, 987 F.3d at
 1034-35, 1040 (affirming a denial of (C) delay where the
 examiner repeatedly reopened prosecution to withdraw her
 own decision after the applicant filed a notice of appeal).
      Sawstop further contends that we should not read “re-
 versing an adverse determination of patentability” to re-
 quire that the claim be suitable for allowance following
 appeal because the separate patent term adjustment pro-
 vision for (A) delay, § 154(b)(1)(A)(iii), expressly references
 “allowable claims.” Sawstop is incorrect. The use of the
 phrase “allowable claims” in the (A) delay provision does
 not implicitly exclude considerations of allowability when
 reading the phrase “reversing an adverse determination of
 patentability” in the (C) delay provisions. Those provisions
 reflect different stages of prosecution during which delay
 may occur and the different reasons for such delay. The act
 giving rise to (A) delay is the PTO’s failure to act after an
 appellate decision “in a case in which allowable claims re-
 main in the application.” The phrase “allowable claims” in
 the (A) delay provision refers to the state of the claims
 when the triggering action—PTO inaction—takes place.
 This is a wholly different context than that of the (C) delay
 provision, “reversing an adverse determination of patenta-
 bility,” which accurately reflects that the appellate change
 of the patentability of the claims is itself the triggering
 event. The acts triggering (A) delay are thus unrelated to
 and independent of the acts giving rise to (C) delay, and

 may have no bearing on the determination of patentability
 under review in any particular appeal.
      Sawstop argues that the Board’s reversal of the exam-
 iner’s anticipation finding of claim 1 was a reversal of an
 adverse determination of patentability, and that the pres-
 ence of the provisional obviousness-type double patenting
 rejection was inapposite as to whether the Board reversed
 that adverse determination of patentability. The problem
 with Sawstop’s position is that the PTO’s “adverse deter-
 mination of patentability” of claim 1 of the ’796 patent was
 based on two grounds: double patenting and anticipation.
 Sawstop only appealed anticipation without addressing the
 provisional double patenting rejection. As a result, the Dis-
 trict Court for the District of Columbia understandably did
 not address the double patenting rejection. Sawstop’s suc-
 cess in reversing the anticipation rejection left the provi-
 sional double patenting rejection in place. Claim 1 of the
 ’796 patent was thus unpatentable both before the appeal
 (because of anticipation and double patenting) and after
 the appeal (because of double patenting). Like the ’496 pa-
 tent, the appellate decision did not reverse an adverse de-
 termination of patentability. See ’796 Decision, 2021 WL
 2021122, at *6.
      Sawstop argues that the remaining rejection did not af-
 fect “patentability” because it was non-statutory (because
 it was an obviousness-type double patenting rejection) and
 provisional (because the obviousness-rendering reference
 was an application rather than a patent). Citing In re Mott,
 539 F.2d 1291, 1296 (C.C.P.A. 1976), Sawstop argues that
 these characteristics mean that the rejection did not have
 any force or effect until the obviousness-rendering refer-
 ence issued and was thus not a rejection that it could ap-
 peal or the District Court could affirm or reject. Sawstop
 is incorrect.
     First, Sawstop itself recognized that the rejection had
 legal effect as it appealed that rejection to the Board and

 did not claim it was illusory. Moreover, Sawstop never ex-
 plained why it could appeal the rejection to the Board un-
 der 35 U.S.C. § 134, but not to the D.C. District Court
 under 35 U.S.C. § 145. Second, on remand, claim 1 re-
 mained subject to the double patenting rejection, which be-
 came non-provisional following issuance of the application
 on which it was based. This occurred prior to issuance of
 the ’496 patent. To overcome that part of the adverse de-
 termination of patentability, Sawstop needed to either can-
 cel claim 1 and put claim 2 into independent form
 (Sawstop’s chosen action) or file a terminal disclaimer. Un-
 der either action, the patent was not allowable following
 the appeal in light of the pending rejection. For these rea-
 sons, we agree with the District Court that the appeal did
 not reverse an adverse determination of patentability as
 that expression is used in 35 U.S.C § 154(b)(1)(C)(iii).
      We also hold that the District Court was correct that
 the ’796 patent was ineligible for (C) delay for the inde-
 pendent reason that the ’796 patent did not issue under a
 decision in the review. The ’796 patent, as issued, did not
 include claim 1 as appealed. Rather, Sawstop cancelled
 claim 1 and replaced it with an independent form of claim
 2, which had been allowed in dependent form prior to the
 appeal. Sawstop fails to explain how the ’796 patent issued
 under a decision in the review. Sawstop argues in reply
 that the statute only requires that the “patent” issue under
 a decision in the review, not the “claim” that was the sub-
 ject of the appeal. However, that does not change the stat-
 utory text that the patent must issue under the decision in
 the review. Here, the only claim that was subject to the
 decision under review was claim 1, which was cancelled
 and thus not part of the issued patent. The ’796 patent
 therefore did not issue under a decision in the review.
                             VI
    For the foregoing reasons, we affirm the judgments of
 the District Court that the PTO did not err in its

 interpretations of § 154(b)(1)(C)(iii) and did not violate the
 APA by refusing to award additional patent term adjust-
 ments for (C) delay for the ’796 patent and the ’476 patent.
