     Dissenting opinion filed by Circuit Judge HUGHES, in
    which Circuit Judges LOURIE, BRYSON, and DYK join.
REYNA, Circuit Judge.
     Congress has prohibited the Director of the United
States Patent and Trademark Office from instituting
inter partes review if the petition requesting that review
is filed more than one year after the petitioner, real party
in interest, or privy of the petitioner is served with a
complaint for patent infringement. 35 U.S.C. § 315(b).
Congress also provided that the Director’s determination
“whether to institute an inter partes review under this
section shall be final and nonappealable.” Id. § 314(d).
The question before us is whether the bar on judicial
review of institution decisions in § 314(d) applies to time-
bar determinations made under § 315(b). In Achates
Reference Publishing, Inc. v. Apple Inc., 803 F.3d 652, 658
(Fed. Cir. 2015), a panel of this court held in the affirma-
tive that a § 315(b) time-bar determination is final and
nonappealable under § 314(d). Today, the court revisits
this question en banc.
    We recognize the strong presumption in favor of judi-
cial review of agency actions. To overcome this presump-
tion, Congress must clearly and convincingly indicate its
intent to prohibit judicial review. We find no clear and
convincing indication of such congressional intent. We
therefore hold that the time-bar determinations under
§ 315(b) are appealable, overrule Achates’s contrary
conclusion, and remand these cases to the panel for
further proceedings consistent with this opinion.
                     I. BACKGROUND
                 A. America Invents Act
    In 2011, Congress passed the Leahy-Smith America
Invents Act (“AIA”), which created inter partes review
(“IPR”) proceedings. See Pub. L. No. 112-29, § 6(a)–(c),
125 Stat. 284, 299–305 (2011); 35 U.S.C. §§ 311–319. IPR

and other post-grant proceedings are intended to be quick
and cost effective alternatives to litigation for third par-
ties to challenge the patentability of issued claims. H.R.
Rep. No. 112-98, pt. 1, at 48 (2011); 157 Cong. Rec. 2,710
(2011) (statement of Sen. Grassley). Sections 311 and 312
of Title 35 establish who may petition for IPR, the
grounds for review in an IPR, the earliest permitted time
for a petition for an IPR, and the requirements of the
petition for an IPR. Under § 311, a person who is not the
owner of a patent may petition the Director to institute
IPR of one or more patent claims on permitted grounds,
alleging unpatentability on certain prior art bases. Sec-
tion 312 provides that the petition must, among other
things, “identif[y], in writing and with particularity, each
claim challenged, the grounds on which the challenge to
each claim is based, and the evidence that supports the
grounds for the challenge to each claim.” 35 U.S.C.
§ 312(a)(3). Section 313 provides that the patent owner
may file a preliminary response to the petition.
    In § 314, subsection (a) prescribes the threshold “de-
termin[ation]” required for the Director to institute: a
“reasonable likelihood” that the petitioner will succeed in
its patentability challenge to at least one of the chal-
lenged patent claims. Subsections (b) and (c) prescribe
the timing of and notice requirements for the institution
decision. And § 314(d) addresses judicial review of the
Director’s IPR institution determination under § 314.
Specifically, § 314(d) provides that “[t]he determination
by the Director whether to institute an inter partes re-
view under this section shall be final and nonappealable.” 2
(emphasis added).

    2  The Director has delegated the authority to insti-
tute IPR to the Patent Trial and Appeal Board (“the
Board”). 37 C.F.R. §§ 42.4(a), 42.108. We have held this
8                          WI-FI ONE, LLC   v. BROADCOM CORP.

    The remainder of the IPR-related provisions of the
AIA go beyond the preliminary procedural requirements
and the preliminary determination regarding likely
unpatentability. Section 315, for example, governs the
relationship between IPRs and other proceedings con-
ducted outside of the IPR process. The provision at issue
in this appeal, § 315(b), provides that “[a]n inter partes
review may not be instituted if the petition requesting the
proceeding is filed more than 1 year after the date on
which the petitioner, real party in interest, or privy of the
petitioner is served with a complaint alleging infringe-
ment of the patent.” This one-year time bar does not
apply to a request for joinder under § 315(c).
    Section 316 addresses the “conduct of” IPRs, including
amendments of the patent and evidentiary standards.
Section 317 addresses settlement.
    If the Director determines to institute IPR, in most
cases, the Board must “issue a final written decision with
respect to the patentability of any patent claim challenged
by the petitioner,” as well as any new claims added during
IPR. 35 U.S.C. § 318(a). Any party to IPR “dissatisfied”
with the final written decision may appeal that decision to
this court. Id. §§ 141(c), 319.
                        B. Achates
    In 2015, a panel of this court decided the same issue
before us today: whether § 314(d) precludes judicial
review of § 315(b) time-bar determinations. In Achates,
the Board canceled certain patent claims through IPR.
803 F.3d at 653. On appeal, the patent owner argued that
the Board acted outside of its statutory authority by

delegation to be constitutionally and statutorily permissi-
ble. Ethicon Endo-Surgery, Inc. v. Covidien LP, 812 F.3d
1023, 1033 (Fed. Cir. 2016).
WI-FI ONE, LLC   v. BROADCOM CORP.                         9

instituting IPR on a petition that was time-barred under
§ 315(b). Id. The panel rejected this argument, holding
that “35 U.S.C. § 314(d) prohibits this court from review-
ing the Board’s determination to initiate IPR proceedings
based on her assessment of the time bar of § 315(b), even
if such assessment is reconsidered during the merits
phase of proceedings and restated as part of the final
written decision.” Id. at 658. According to the panel, the
Board’s misinterpretation of § 315(b) does not constitute
ultra vires agency action that might otherwise support
judicial review. Id. at 658–59. Concluding that this court
is barred from reviewing § 315(b) decisions, the panel
dismissed for lack of jurisdiction. Id. at 659.
                          C. Cuozzo
    Subsequent to our decision in Achates, the Supreme
Court decided Cuozzo Speed Technologies, LLC v. Lee, 136
S. Ct. 2131 (2016). In Cuozzo, the Court addressed
whether § 314(d) bars judicial review of determinations
regarding compliance with § 312(a)(3), i.e., whether the
petition identified with sufficient particularity “each
claim challenged, the grounds on which the challenge to
each claim is based, and the evidence that supports the
grounds for the challenge to each claim.” Id. at 2139–42.
     The Supreme Court’s analysis of § 314(d) began with
a recognition of the “‘strong presumption’ in favor of
judicial review.” Id. at 2140 (quoting Mach Mining, LLC
v. EEOC, 135 S. Ct. 1645, 1651 (2015)). The Court ex-
plained that the presumption of judicial review “may be
overcome by ‘“clear and convincing”’ indications, drawn
from ‘specific language,’ ‘specific legislative history,’ and
‘inferences of intent drawn from the statutory scheme as a
whole,’ that Congress intended to bar review.” Id. (quot-
ing Block v. Cmty. Nutrition Inst., 467 U.S. 340, 349–50
(1984)).
    The Supreme Court held that the presumption in fa-
vor of judicial review was overcome regarding whether a
10                          WI-FI ONE, LLC   v. BROADCOM CORP.

petition met the requirements of § 312(a)(3). Id. at 2142.
The Court considered the dispute about § 312(a)(3)’s
particularity requirement to be “an ordinary dispute” over
the Director’s institution decision. Id. at 2139. The Court
concluded that § 314(d) “must, at the least, forbid an
appeal that attacks a ‘determination . . . whether to
institute’ review by raising this kind of legal question and
little more.” Id. (alteration in original). The Court spoke
of “the kind of initial determination at issue here—that
there is a ‘reasonable likelihood’ that the claims are
unpatentable on the grounds asserted.” Id. at 2140
(quoting § 314(a)). The Court held:
     where a patent holder merely challenges the Pa-
     tent Office’s “determin[ation] that the information
     presented in the petition . . . shows that there is a
     reasonable likelihood” of success “with respect to
     at least 1 of the claims challenged,” § 314(a), or
     where a patent holder grounds its claim in a stat-
     ute closely related to that decision to institute in-
     ter partes review, § 314(d) bars judicial review.
Id. at 2142 (alterations in original). The Supreme Court
noted that the question of whether a petition was pleaded
with particularity amounted to “little more than a chal-
lenge to the Patent Office’s conclusion, under § 314(a),
that the ‘information presented in the petition’ warranted
review.” Id. In the Court’s words, a challenge to the
sufficiency of the “information presented in the petition”
was a nonappealable “mine-run” claim. Id. at 2136, 2142.
    The dissent contends that the statutory language of
§ 314(d) “is absolute and provides no exceptions.” Dis-
senting Op. at 8. The Supreme Court in Cuozzo rejected
this contention. The Court made clear that its holding
was limited; it expressly left open the potential for review,
under certain circumstances, of decisions to institute IPR.
First, the Court emphasized that its “interpretation
applies where the grounds for attacking the decision to
WI-FI ONE, LLC   v. BROADCOM CORP.                       11

institute inter partes review consist of questions that are
closely tied to the application and interpretation of stat-
utes related to” the institution decision, emphasizing the
“under this section” language of § 314(d) in the citation
that follows. 136 S. Ct. at 2141. In stating its holding
(quoted above), the Court further tied the “closely related”
language to the specific “reasonable likelihood” determi-
nation made under § 314(a). Id. at 2142. The Court
expressly declined to “decide the precise effect of § 314(d)
on appeals that implicate constitutional questions, that
depend on other less closely related statutes, or that pre-
sent other questions of interpretation that reach, in terms
of scope and impact, well beyond ‘this section.’” 3 Id. at
2141 (emphases added). Second, the Court noted that its
holding does not “categorically preclude review of a final
decision where a petition fails to give ‘sufficient notice’
such that there is a due process problem with the entire
proceeding.” Id. Finally, the Court wrote that its holding
does not “enable the agency to act outside its statutory
limits by, for example, canceling a patent claim for ‘indef-
initeness under § 112’ in inter partes review.” Id. at
2141–42. “Such ‘shenanigans,’” according to the Court,
“may be properly reviewable in the context of § 319 and
under the Administrative Procedure Act.” Id. at 2142.
                    D. The Present Appeal
     In 2010, Telefonaktiebolaget LM Ericsson (“Ericsson”)
filed its complaint for infringement of U.S. Patent Nos.

    3   The dissent’s reliance on Briscoe v. Bell, 432 U.S.
404 (1977), is misplaced. Unlike Cuozzo, Briscoe does not
address whether a statutory section precluding judicial
review of determinations “under this section” would apply
to determinations made under any other section of that
statute or a different statute.

6,772,215 (“’215 patent”), 6,466,568 (“’568 patent”), and
6,424,625 (“’625 patent”) in the United States District
Court for the Eastern District of Texas against multiple
defendants. 4 The case progressed to a jury trial, where
the jury found that the defendants infringed the asserted
claims. This court reviewed that determination. Erics-
son, Inc. v. D-Link Sys., Inc., 773 F.3d 1201 (Fed. Cir.
2014). Broadcom Corporation (“Broadcom”), the appellee
here, was never a defendant in that litigation.
     In 2013, Broadcom filed three separate petitions for
IPR of the ’215, ’568, and ’625 patents. 5 When Broadcom
filed the IPR petitions, Ericsson owned these patents.
During the pendency of the IPRs, Ericsson transferred
ownership of the three patents to Wi-Fi One, LLC (“Wi-
Fi”).
    In response to Broadcom’s petitions, Wi-Fi argued
that the Director was prohibited from instituting review
on any of the three petitions. Specifically, Wi-Fi argued
that the Director lacked authority to institute IPR under
§ 315(b) because Broadcom was in privity with defendants
that were served with a complaint in the Eastern District
of Texas litigation. Wi-Fi alleged that the IPR petitions
were therefore time-barred under § 315(b) because Erics-

     4  Ericsson brought suit against D-Link Systems,
Inc., Netgear, Inc., Acer, Inc., Acer America Corp., Gate-
way, Inc., Dell, Inc., Belkin International, Inc., Toshiba
America Information Systems, Inc., and Toshiba Corp.
Intel Corp. intervened and Ericsson amended its com-
plaint to add Intel as a defendant. See Ericsson Inc. v. D-
Link Sys., Inc., No. 6:10-CV-473, 2013 WL 4046225, at
*24 n.1 (E.D. Tex. Aug. 6, 2013), aff’d in part, vacated in
part, rev’d in part, 773 F.3d 1201 (Fed. Cir. 2014).
    5   The technical aspects of the patents are not rele-
vant to this opinion.
WI-FI ONE, LLC   v. BROADCOM CORP.                      13

son, the patents’ previous owner, had already asserted
infringement in district court against defendants that
were in privity with petitioner Broadcom more than a
year prior to the filing of the petitions.
    Wi-Fi filed a motion seeking discovery regarding in-
demnity agreements, defense agreements, payments, and
email or other communications between Broadcom and
the defendants in the Eastern District of Texas litigation.
The Board denied both the motion and Wi-Fi’s subsequent
motion for rehearing. Wi-Fi petitioned this court for a
writ of mandamus, which we denied. In re Telefonaktiebo-
laget LM Ericsson, 564 F. App’x 585 (Fed. Cir. 2014).
    The Board instituted IPR on the challenged claims,
and issued Final Written Decisions finding the challenged
claims unpatentable. In the Final Written Decisions, the
Board determined that Wi-Fi had not shown that Broad-
com was in privity with the defendants in the Eastern
District of Texas litigation, and therefore, the IPR peti-
tions were not time-barred under § 315(b). Broadcom
Corp. v. Wi-Fi One, LLC, No. IPR2013-00601, 2015 WL
1263008, at *4–5 (P.T.A.B. Mar. 6, 2015); Broadcom Corp.
v. Wi-Fi One, LLC, No. IPR2013-00602, 2015 WL
1263009, at *4 (P.T.A.B. Mar. 6, 2015); Broadcom Corp.
v. Wi-Fi One, LLC, No. IPR2013-00636, 2015 WL
1263010, at *4 (P.T.A.B. Mar. 6, 2015).
    Wi-Fi appealed the Final Written Decisions, arguing,
among other things, that this court should reverse or
vacate the Board’s time-bar determinations. A panel of
this court rejected Wi-Fi’s arguments, reasoning that
Achates renders the § 315(b) time-bar rulings nonappeal-
able. See Wi-Fi One, LLC v. Broadcom Corp., 837 F.3d
1329, 1333 (Fed. Cir. 2016) (“Wi-Fi does not dispute that
Achates renders its challenge to the Board’s timeliness
ruling nonappealable if Achates is still good law.”). Be-
cause the panel concluded that Cuozzo did not implicitly
overrule Achates, it held Wi-Fi’s time-bar challenges to be
14                          WI-FI ONE, LLC   v. BROADCOM CORP.

unreviewable, and affirmed. Id. at 1334–35, 1340; see
also Wi-Fi One, LLC v. Broadcom Corp., 668 F. App’x 893
(Fed. Cir. 2016) (summarily affirming the time-bar deci-
sions on the ’568 and ’625 patents).
    Wi-Fi petitioned for rehearing en banc. We granted
Wi-Fi’s petition to consider whether we should overrule
Achates and hold that the Director’s § 315(b) time-bar
determinations are subject to judicial review. The ques-

                       II. DISCUSSION
    As with any agency action, we apply the “strong pre-
sumption” favoring judicial review of administrative
actions, including the Director’s IPR institution deci-
sions. 6 Cuozzo, 136 S. Ct. at 2140; see also Gutierrez de

     6     Final decisions of the PTO are reviewed according
to the standards provided in the Administrative Proce-
dure Act (“APA”). Cuozzo, 136 S. Ct. at 2142; Unwired
Planet, LLC v. Google Inc., 841 F.3d 1376, 1379 (Fed. Cir.
2016). And 28 U.S.C. § 1295(a)(4)(A) provides this court
with exclusive jurisdiction over an appeal from a decision
of “the Patent Trial and Appeal Board of the United
States Patent and Trademark Office with respect
to . . . inter partes review under title 35.”
WI-FI ONE, LLC   v. BROADCOM CORP.                        15

Martinez v. Lamagno, 515 U.S. 417, 424 (1995) (“[F]ederal
judges traditionally proceed from the ‘strong presumption
that Congress intends judicial review.’”); Bowen v. Mich.
Acad. of Family Physicians, 476 U.S. 667, 670 (1986);
United States v. Nourse, 34 U.S. (9 Pet.) 8, 28–29 (1835).
Accordingly, if a statute is “reasonably susceptible” to an
interpretation allowing judicial review, we must adopt
such an interpretation. Kucana v. Holder, 558 U.S. 233,
251 (2010); Gutierrez de Martinez, 515 U.S. at 434.
    In view of this strong presumption, we will abdicate
judicial review only when Congress provides a “clear and
convincing” indication that it intends to prohibit review.
Cuozzo, 136 S. Ct. at 2140; see Lindahl v. Office of Pers.
Mgmt., 470 U.S. 768, 778 (1985); Block, 467 U.S. at 349–
50; Return Mail, Inc. v. U.S. Postal Serv., 868 F.3d 1350,
1357 (Fed. Cir. 2017).
     We find no clear and convincing indication in the spe-
cific statutory language in the AIA, the specific legislative
history of the AIA, or the statutory scheme as a whole
that demonstrates Congress’s intent to bar judicial review
of § 315(b) time-bar determinations. See Cuozzo, 136 S.
Ct. at 2140. The parties have not cited, nor are we aware
of, any specific legislative history that clearly and con-
vincingly indicates congressional intent to bar judicial
review of § 315(b) time-bar determinations. We review
the statutory language and the statutory scheme in turn.
    Starting with the statutory language, § 314(d) pro-
vides that “[t]he determination by the Director whether to
institute an inter partes review under this section shall be
final and nonappealable.” (emphasis added). The natural
reading of the statute limits the reach of § 314(d) to the
determination by the Director whether to institute IPR as
set forth in § 314. Subsection (a) of § 314—the only
subsection addressing substantive issues that are part of
the Director’s determination “under this section”—reads:
16                          WI-FI ONE, LLC   v. BROADCOM CORP.

     (a) Threshold.--The Director may not authorize
     an inter partes review to be instituted unless the
     Director determines that the information present
     in the petition filed under section 311 and any re-
     sponse filed under section 313 shows that there is
     a reasonable likelihood that the petitioner would
     prevail with respect to at least 1 of the claims
     challenged in the petition.
    Subsection (a) does only two things: it identifies a
threshold requirement for institution, and as Cuozzo
recognized, it grants the Director discretion not to insti-
tute even when the threshold is met. 136 S. Ct. at 2140
(“[T]he agency’s decision to deny a petition is a matter
committed to the Patent Office’s discretion.”). It does not
address any other issue relevant to an institution deter-
mination. The language of § 314(a) defines the threshold
in terms of determinations that are focused on the pa-
tentability merits of particular claims. This determina-
tion is only preliminary, aimed just at what is reasonably
likely to be decided when patentability is fully addressed,
should an IPR be instituted. See Cuozzo, 136 S. Ct. at
2140. In referring to the preliminary patentability de-
termination, the Court characterized the Director’s discre-
tion regarding institution as being “akin to decisions
which, in other contexts, we have held to be unreviewa-
ble.” Id. 7

     7  Examples include an agency’s discretionary deci-
sion not to initiate a proceeding, Cuozzo, 136 S. Ct. at
2140, a grand jury’s determination of probable cause, id.,
and a court’s denial of summary judgment, see Ortiz v.
Jordan, 562 U.S. 180, 183–84 (2011); Switz. Cheese Ass’n,
Inc. v. E. Horne’s Market, Inc., 385 U.S. 23, 25 (1966);
Function Media, LLC v. Google Inc., 708 F.3d 1310, 1322
(Fed. Cir. 2013).
WI-FI ONE, LLC   v. BROADCOM CORP.                        17

    In contrast, § 315(b) controls the Director’s authority
to institute IPR that is unrelated to the Director’s prelim-
inary patentability assessment or the Director’s discretion
not to initiate an IPR even if the threshold “reasonable
likelihood” is present. Section 315(b) reads:
    (b) Patent Owner’s Action. An inter partes re-
    view may not be instituted if the petition request-
    ing the proceeding is filed more than 1 year after
    the date on which the petitioner, real party in in-
    terest, or privy of the petitioner is served with a
    complaint alleging infringement of the patent.
    The time limitation set forth in the preceding sen-
    tence shall not apply to a request for joinder un-
    der subsection (c).
    The dissent states that § 315(b) “does not go to the
merits of the petition.” Dissenting Op. at 5. This is
correct. The time-bar decision is nowhere referred to in
§ 314(a).    Additionally, the time bar is not focused on
particular claims, whereas § 314(a)’s threshold determi-
nation is; the time bar involves only the time of service of
a complaint alleging infringement “of the patent.” Noth-
ing in § 315(b) sets up a two-stage process for addressing
the time bar: the time-bar determination may be decided
fully and finally at the institution stage.
    The time-bar determination, therefore, is not akin to
either the non-initiation or preliminary-only merits
determinations for which unreviewability is common in
the law, in the latter case because the closely related final
merits determination is reviewable. See supra note 7.
Because § 314(a) does not mention this distinct issue, the
PTO’s position that the time-bar determination is unre-
viewable runs counter to the principle, as reflected in
Cuozzo, that favors reading the statute to comport with,
18                         WI-FI ONE, LLC   v. BROADCOM CORP.

not depart from, familiar approaches to comparable
issues. 8
    This reading is consistent with the overall statutory
scheme as understood through the lens of Cuozzo’s di-
rective to examine the statutory scheme in terms of what
is “closely related” to the § 314(a) determination. The
Supreme Court in Cuozzo stated that “§ 314(d) bars
judicial review” both when “a patent holder merely chal-
lenged the Patent Office’s ‘determin[ation] that the infor-
mation presented in the petition . . . shows that there is a
reasonable likelihood’ of success ‘with respect to at least 1
of the claims challenged,’ § 314(a)” and, in addition, when
“a patent holder grounds its claim in a statute closely
related to that decision to institute inter partes review.”
136 S. Ct. at 2142 (alterations in original) (emphasis
added). The statutory scheme demonstrates that several
sections of the AIA, such as the preliminary procedural
requirements stated in §§ 311–13, relate more closely to
the determination by the Director. The “reasonable
likelihood” determination under § 314(a) is clearly about
whether “the claims are unpatentable on the grounds
asserted.” Id. at 2140. The Court’s statement of its
holding thus strongly points toward unreviewability being
limited to the Director’s determinations closely related to
the preliminary patentability determination or the exer-
cise of discretion not to institute.

     8   Although § 314(d) uses language somewhat differ-
ent from the language of precursor provisions, there is no
reason to infer a deliberate broadening of the scope of
nonreviewability—certainly not a clear and convincing
reason. Indeed, the Court in Cuozzo stressed the similari-
ty of § 314(d) to its precursors, without mentioning differ-
ences. 136 S. Ct. at 2140.
WI-FI ONE, LLC   v. BROADCOM CORP.                        19

    Whether a petitioner has complied with § 315(b) is not
such a determination, as it has nothing to do with the
patentability merits or discretion not to institute. The
time-bar provision contrasts with many of the preliminary
procedural requirements stated in §§ 311–13, which
relate to the Director’s ability to make an informed pre-
liminary patentability determination pursuant to
§ 314(a). Specifically, § 315(b) time-bar determinations
are fundamentally different from those evaluating the
satisfaction of § 312(a)(3)’s requirements, at issue in
Cuozzo. Section 312(a)(3) demands particularity as to
“each claim challenged, the grounds on which the chal-
lenge to each claim is based, and the evidence that sup-
ports the grounds for the challenge to each claim.” That
requirement is closely tied to the Director’s determination
of a “reasonable likelihood” of unpatentability of at least
one claim. The time bar is not.
    The issue that Wi-Fi appeals also is not “some minor
statutory technicality.” Cuozzo, 136 S. Ct. at 2140. The
time bar is not merely about preliminary procedural
requirements that may be corrected if they fail to reflect
real-world facts, but about real-world facts that limit the
agency’s authority to act under the IPR scheme. 9 The

    9   For instance, the dissent conflates “real party in
interest” as used in § 312(a)(2) and § 315(b), and claims
that “§ 312(a)(2) is part and parcel of the timeliness
inquiry under § 315.” Dissenting Op. at 10. This is
incorrect. For example, if a petition fails to identify all
real parties in interest under § 312(a)(2), the Director can,
and does, allow the petitioner to add a real party in
interest. See, e.g., Intel Corp. v. Alacritech, Inc., No.
IPR2017-01392, Paper No. 11, at 23 (P.T.A.B. Nov. 30,
2017); Elekta, Inc. v. Varian Medical Sys., Inc., No.
IPR2015–01401, 2015 WL 9898990, at *4, *6 (P.T.A.B.
20                          WI-FI ONE, LLC   v. BROADCOM CORP.

timely filing of a petition under § 315(b) is a condition
precedent to the Director’s authority to act. It sets limits
on the Director’s statutory authority to institute, balanc-
ing various public interests. And like § 315 as a whole, it
governs the relation of IPRs to other proceedings or
actions, including actions taken in district court.
    Thus, the statutory scheme as a whole demonstrates
that § 315 is not “closely related” to the institution deci-
sion addressed in § 314(a), and it therefore is not subject
to § 314(d)’s bar on judicial review. Cuozzo, 136 S. Ct. at
2142; cf. Credit Acceptance Corp. v. Westlake Servs., 859
F.3d 1044, 1049–51 (Fed. Cir. 2017) (holding that a simi-
lar nonappealability provision with respect to post-grant
review, 35 U.S.C. § 324(e), does not preclude our review of
an estoppel determination under 35 U.S.C. § 325(e)(1)).
Accordingly, our review of the statutory language and the
statutory scheme reveals no clear and convincing indica-
tion of Congress’s intent to bar judicial review of § 315(b)
time-bar determinations.
    Enforcing statutory limits on an agency’s authority to
act is precisely the type of issue that courts have histori-
cally reviewed. See, e.g., City of Arlington v. F.C.C., 569
U.S. 290, 307 (2013); Bowen, 476 U.S. at 671; Leedom v.
Kyne, 358 U.S. 184, 190 (1958). As a statutory limit on
the Director’s ability to institute IPR, the § 315(b) time

Dec. 31, 2015). For this reason, the PTO has established
procedures to rectify noncompliance of § 312(a)(2). Lu-
mentum Holdings, Inc. v. Capella Photonics, Inc., No.
IPR2015-00739, 2016 WL 2736005, at *3 (P.T.A.B. Mar. 4,
2016) (precedential); 37 C.F.R. §§ 42.8(a)(3), 42.8(b)(1). In
contrast, if a petition is not filed within a year after a real
party in interest, or privy of the petitioner is served with
a complaint, it is time-barred by § 315(b), and the petition
cannot be rectified and in no event can IPR be instituted.

bar is such an issue. We hold that time-bar determina-
tions under § 315(b) are reviewable by this court.
                       III. CONCLUSION
     The Supreme Court in Cuozzo instructed that the
“strong presumption” favoring judicial review “may be
overcome by ‘“clear and convincing”’ indications, drawn
from ‘specific language,’ ‘specific legislative history,’ and
‘inferences of intent drawn from the statutory scheme as a
whole,’ that Congress intended to bar review.” 136 S. Ct.
at 2140. Finding no such clear and convincing indica-
tions, we hold that the Director’s time-bar determinations
under § 315(b) are not exempt from judicial review, and
overrule Achates’s contrary conclusion. We do not decide
today whether all disputes arising from §§ 311–14 are
final and nonappealable. Our holding applies only to the
appealability of § 315(b) time-bar determinations. We
remand for the panel to consider in the first instance the
merits of Wi-Fi’s time-bar appeal.

O’MALLEY, Circuit Judge, concurring.
     I agree with much of the majority’s thoughtful reason-
ing, and I certainly agree with its conclusion that time-
bar determinations under 35 U.S.C. § 315(b) are not
exempt from judicial review. I write separately because,
in my view, the question presented for en banc rehearing
in this case is much simpler than the majority’s analysis
implies; it turns on the distinction between the Director’s
authority to exercise discretion when reviewing the ade-
quacy of a petition to institute an inter partes review
(“IPR”) and authority to undertake such a review in the
first instance. If the United States Patent and Trade-
mark Office (“PTO”) exceeds its statutory authority by
instituting an IPR proceeding under circumstances con-
trary to the language of § 315(b), our court, sitting in its
proper role as an appellate court, should review those
determinations. Indeed, we should address those deci-
sions in order to give effect to the congressionally imposed
statutory limitations on the PTO’s authority to institute
IPRs.
     As we explained in Intellectual Ventures II LLC v.
JPMorgan Chase & Co., 781 F.3d 1372 (Fed. Cir. 2015),
when assessing whether we may exercise jurisdiction over
an appeal from institution decisions regarding covered
business method patents (“CBMs”), Congress consistently
differentiated between petitions to institute and the act of
institution in the AIA. Id. at 1376. The former is what a
party seeking to challenge a patent in a CBM proceeding,
a derivation proceeding, a post-grant proceeding, or an
IPR files—and of which the PTO reviews the sufficiency—
and the latter is what the Director is authorized to do. Id.
Because only the Director or her delegees may “institute”
a proceeding, § 315(b)’s bar on institution is necessarily
4                           WI-FI ONE, LLC   v. BROADCOM CORP.

directed to the PTO, not those filing a petition to institute.
See id.
     The PTO’s own regulations support this reading
of § 315(b); they clearly consider the possibility that the
Board might mistakenly take actions in excess of its
statutory jurisdiction. For example, Part 42 of Title 37 in
the Code of Federal Regulations “governs proceedings
before the Patent Trial and Appeal Board.” 37 C.F.R.
§ 42.1(a) (2016). In addressing “Jurisdiction” for these
proceedings, Part 42 expressly requires that “[a] petition
to institute a trial must be filed with the Board consistent
with any time period required by statute.” Id. § 42.3(b);
see also id. § 42.2 (identifying IPR proceedings as falling
within the definition of “trial”). A straightforward read-
ing of these regulations indicates that the PTO believed,
at least at the time it issued those regulations, that it
would not have statutory jurisdiction or authority to
institute proceedings—including IPRs—in response to
petitions to institute filed outside the time limit set by
statute for such filings, regardless of the adequacy of
those petitions.
    Section 314(d)’s bar on appellate review is directed to
the Director’s assessment of the substantive adequacy of a
timely filed petition. Because § 315(b)’s time bar has
nothing to do with the substantive adequacy of the peti-
tion and is directed, instead, to the Director’s authority to
act, § 314(d) does not apply to decisions under that provi-
sion.
     This conclusion not only is consistent with, but, in my
view, is dictated by the Supreme Court’s reasoning in
Cuozzo Speed Technologies, LLC v. Lee, 136 S. Ct. 2131
(2016). There, the Court considered whether § 314(d)
bars review of determinations by the PTO that a petition
for IPR complies, at least implicitly, with the “particulari-
ty” requirement set forth in § 312(a)(3). 136 S. Ct. at
2138–39. The majority here correctly notes that the
WI-FI ONE, LLC   v. BROADCOM CORP.                       5

Court in Cuozzo “recognize[d] the ‘strong presumption’ in
favor of judicial review that we apply when we interpret
statutes, including statutes that may limit or preclude
review.” Id. at 2140 (quoting Mach Mining, LLC v.
E.E.O.C., 135 S. Ct. 1645, 1650–51 (2015) (internal quota-
tion marks omitted)). The Court observed, however, that
this presumption could be overcome by “clear and convinc-
ing” indications, drawn from “specific language,” “specific
legislative history,” and “inferences of intent drawn from
the statutory scheme as a whole,” that Congress intended
to bar review. Id. (quoting Block v. Cmty. Nutrition Inst.,
467 U.S. 340, 349–50 (1984)).
    In deciding that the presumption in favor of judicial
review was overcome in that case, the Court analyzed and
distinguished Lindahl v. Office of Personnel Management,
470 U.S. 768 (1985). Lindahl involved the question of
whether courts can review disability determinations for
federal employees made by a federal agency. 470 U.S. at
771. According to the majority in Cuozzo, Lindahl in-
volved the construction of a statute that (1) directed an
agency to “determine questions of liability;” (2) made
those determinations “final,” “conclusive,” and “not sub-
ject to review;” and (3) barred courts from revisiting the
“factual underpinnings of . . . disability determinations.”
136 S. Ct. at 2141 (quoting Lindahl, 470 U.S. at 771, 791).
The Court observed, however, that the same statute
permitted courts to consider claims alleging, for example,
that the agency “substantial[ly] depart[ed] from im-
portant procedural rights.” Id. (quoting Lindahl, 470 U.S.
at 791).
    The Cuozzo majority characterized Lindahl’s interpre-
tation of its particular statute as “preserv[ing] the agen-
cy’s primacy over its core statutory function in accord
with Congress’ intent,” and declared that its “interpreta-
tion of the ‘No Appeal’ provision [in the AIA] has the same
effect.” Id. This is because Congress, in enacting the
AIA, recognized that the “core statutory function” of the
6                          WI-FI ONE, LLC   v. BROADCOM CORP.

PTO is to make patentability determinations, and chose
to insulate from judicial review preliminary determina-
tions by the PTO as to whether IPR petitions “show[] that
there is a reasonable likelihood that the petitioner would
prevail with respect to at least 1 of the claims challenged
in the petition.” 35 U.S.C. § 314(a); see Cuozzo, 136 S. Ct.
at 2141 (“The text of the ‘No Appeal’ provision, along with
its place in the overall statutory scheme, its role alongside
the Administrative Procedure Act, the prior interpreta-
tion of similar patent statutes, and Congress’ purpose in
crafting IPR, all point in favor of precluding review of the
[PTO]’s institution decisions.” (emphasis added)). For this
reason, the Court found that Cuozzo’s claim that an IPR
petition “was not pleaded ‘with particularity’ under § 312
[wa]s little more than a challenge to the [PTO]’s conclu-
sion, under § 314(a), that the ‘information presented in
the petition’ warranted review.” Id. at 2142 (citation
omitted).
    Section 315(b)’s time bar falls squarely on the other
side of Cuozzo’s appealability ledger, for it is not “closely
tied to the application and interpretation of statutes
related to the [PTO]’s decision to initiate [IPR].” Id. at
2141. Section 315(b) does not contemplate that the PTO
render a decision related to patentability—it simply
places a limit on the PTO’s authority to institute IPRs
that is based on a comparison of two or more dates. And
it does so with the unambiguous phrase “[a]n [IPR] may
not be instituted if . . . .” 35 U.S.C. § 315(b) (emphasis
added). In contrast with the Director’s § 314(a) determi-
nation, which involves the preliminary application of
patentability principles, no such decision is contemplated
in § 315(b). See N.L.R.B. v. SW Gen., Inc., 137 S. Ct. 929,
940 (2017) (describing a clause that “speaks to who ‘may
not’ be an acting officer” as an imperative).
    Put another way, § 315(b) codifies one of the “im-
portant procedural rights” that Congress chose to afford
patent owners in the IPR context. Lindahl, 470 U.S. at
WI-FI ONE, LLC   v. BROADCOM CORP.                        7

791. Allowing judicial review of erroneous determinations
by the PTO as to whether the § 315(b) time bar applies
would prevent the agency from “act[ing] outside its statu-
tory limits,” one of the categories of “shenanigans” envi-
sioned by the majority in Cuozzo. 136 S. Ct. at 2141–42.
     A determination by the PTO whether an IPR petition
is time-barred under § 315(b) is entirely unrelated to the
agency’s “core statutory function” of determining whether
claims are or are not patentable. Id. at 2141 (quoting
Lindahl, 470 U.S. at 791). Unlike the threshold merits
inquiry subsumed within § 314(a), no technical expertise
is required to calculate whether a petition is “filed more
than 1 year after the date on which the petitioner, real
party in interest, or privy of the petitioner is served with
a complaint alleging infringement of the patent.” 35
U.S.C. § 315(b).
    Congress is well versed in establishing statutory time
bars. Congressional discretion should control the applica-
tion of such time bars, not that of the Director of the PTO.
I do not see the need to say more.

HUGHES, Circuit Judge, joined by LOURIE, BRYSON, and
DYK, Circuit Judges, dissenting.
    Congress barred judicial review of the Patent and
Trademark Office (PTO) Director’s decision to institute
inter partes review (IPR) in 35 U.S.C. § 314(d). The
majority opinion, however, limits this prohibition to the
Director’s assessment of the criteria for instituting review
set forth in § 314. Accordingly, this court finds that
§ 314(d) does not apply to other preliminary determina-
tions, such as whether the petition was timely filed. I do
not agree with such a narrow reading of the statute,
which not only contradicts the statutory language, but is
also contrary to the Supreme Court’s construction of that
language in Cuozzo Speed Technologies, LLC v. Lee, 136
S. Ct. 2131 (2016).
    In Cuozzo, the Supreme Court held that § 314(d) pro-
hibited judicial review of “questions that are closely tied
to the application and interpretation of statutes related to
the Patent Office’s decision to initiate inter partes re-
view,” including questions of compliance with 35 U.S.C.
§ 312(a)(3)’s petition requirements. 136 S. Ct. at 2141.
35 U.S.C. § 315(b), which describes when an IPR may be
“instituted,” is even more closely related to institution
decisions than § 312(a)(3)—which does not use the word
“institute.” In my view, Cuozzo confirms that § 314(d) is
not limited to the merits of the petition, but also bars
judicial review of closely related issues such as the peti-
tion’s timeliness. Because the majority opinion is incon-
sistent with Cuozzo and the plain meaning of § 314(d), I
respectfully dissent.

                             I
    Our inquiry should start and end with the words of
the statute. The APA exempts agency actions from judi-
cial review “to the extent that statutes preclude judicial
review.” 5 U.S.C. § 701. There is a “strong presumption
that Congress intends judicial review of administrative
action” and any contrary intent must be clear and con-
vincing. Bowen v. Mich. Acad. of Family Physicians, 476
U.S. 667, 670–71 (1986). This presumption, of course, is
not insurmountable. Congress can enact specific statutes
to bar review, or the legislative history might manifest
Congress’s intent to do so. Id. at 673. Even in the ab-
sence of an express prohibition, the overall statutory
structure might indicate that Congress sought to prohibit
judicial review. See United States v. Fausto, 484 U.S. 439,
447–48 (1988); Block v. Cmty. Nutrition Inst., 467 U.S.
340, 352 (1984).
    Congress’s intent to prohibit judicial review of the
Board’s IPR institution decision is clear and unmistaka-
ble. Section 314(d) states “[t]he determination by the
Director whether to institute an inter partes review under
this section shall be final and nonappealable.” (emphasis
added.) The statute calls out a specific agency determina-
tion, and expressly prohibits courts from reviewing that
decision. “Absent persuasive indications to the contrary,
we presume Congress says what it means and means
what it says.” Simmons v. Himmelreich, 136 S. Ct. 1843,
1848 (2016).
    Cuozzo confirms this interpretation of § 314(d).
There, the Supreme Court found that clear and convinc-
ing indications overcame the presumption in favor of
judicial reviewability with respect to IPR institution
decisions. Cuozzo, 136 S. Ct. at 2140. To reach this
conclusion, the Court looked to the plain language of the
statute, and stressed that whether the “Patent Office
unlawfully initiated its agency review is not appealable”
WI-FI ONE, LLC   v. BROADCOM CORP.                          5

because “that is what § 314(d) says.” Id. at 2139 (empha-
sis added).     Cuozzo also foreclosed any notion that
§ 314(d) only applies to the question of whether the peti-
tion raises a reasonable likelihood of invalidity. See id. at
2141. Instead, the statute prohibits judicial review of
“questions that are closely tied to the application and
interpretation of statutes related to the Patent Office’s
decision to initiate inter partes review.” Id.
     The petition’s timeliness under § 315(b) is part of the
Board’s institution decision, and is therefore barred from
judicial review. Section 315(b) states that “[a]n inter
partes review may not be instituted if the petition re-
questing the proceeding is filed more than 1 year after the
date on which the petitioner, real party in interest, or
privy of the petitioner is served with a complaint alleging
infringement of the patent.” The question of timeliness
does not go to the merits of the petition, nor does it be-
come part of the PTO’s final determination. Instead, the
PTO evaluates timeliness within the context of the PTO’s
preliminary determination of whether to institute IPR at
all. Accordingly, timeliness under § 315(b) is plainly a
question “closely tied” to the Director’s decision to insti-
tute. Indeed, it is a specific requirement for “institution.”
Moreover, although Justice Alito disagreed with the
ultimate result in Cuozzo, even he recognized that “the
petition’s timeliness, no less than the particularity of its
allegations, is ‘closely tied to the application and interpre-
tation of statutes related to the Patent Office’s decision to
initiate . . . review,’ and the Court says that such ques-
tions are unreviewable.” Id. at 2155 (Alito, J., concurring
in part and dissenting in part) (alteration in original).
    This court, however, confines the scope of the judicial
review bar in § 314(d) to “the determination by the Direc-
tor whether to institute IPR as set forth in § 314,” which
establishes the reasonable likelihood standard for insti-
tuting review. Maj. Op. at 15. But again, Cuozzo already
held that § 314(d) is not limited to the Director’s reasona-
6                           WI-FI ONE, LLC   v. BROADCOM CORP.

ble likelihood determination. 136 S. Ct. at 2141. The
Supreme Court rejected the notion that the presumption
of judicial review permits courts to review “any issue
bearing on the Patent Office’s preliminary decision to
institute inter partes review.” Id. Rather, the Supreme
Court explained that “Congress has told the Patent Office
to determine whether inter partes review should proceed,
and it has made the agency’s decision ‘final’ and ‘nonap-
pealable.’ § 314(d). Our conclusion that courts may not
revisit this initial determination gives effect to this statu-
tory command.” Id.
    To sidestep this binding precedent, the majority states
that § 315(b) is appealable because “the time-bar deter-
mination may be decided fully and finally at the institu-
tion stage.” Maj. Op. at 17. And the majority suggests
that § 314(d) is limited to “non-initiation or preliminary-
only merits determinations for which unreviewability is
common in the law.” Id. But if § 314(d) only applies to
issues that are incorporated into the final written deci-
sion, then the appeal bar essentially becomes a prohibi-
tion on interlocutory appeal.        The Supreme Court
expressly rejected this interpretation in Cuozzo. 136 S. Ct.
at 2140. As the Court explained:
    The dissent, like the panel dissent in the Court of
    Appeals, would limit the scope of the “No Appeal”
    provision to interlocutory appeals, leaving a court
    free to review the initial decision to institute re-
    view in the context of the agency's final deci-
    sion. We cannot accept this interpretation. It
    reads into the provision a limitation (to interlocu-
    tory decisions) that the language nowhere men-
    tions and that is unnecessary. The Administrative
    Procedure Act already limits review to final agen-
    cy decisions. The Patent Office’s decision to initi-
    ate inter partes review is “preliminary,” not
    “final.” And the agency's decision to deny a peti-
    tion is a matter committed to the Patent Office’s
WI-FI ONE, LLC   v. BROADCOM CORP.                        7

    discretion. So, read as limited to such preliminary
    and discretionary decisions, the “No Appeal” pro-
    vision would seem superfluous.
Id. (citations omitted).
    The majority concludes that the appeal bar does not
apply to “limits on the Director’s statutory authority to
institute,” Maj Op. at 20. But this position was clearly
rejected in Cuozzo. 136 S. Ct. at 2139–40. Even setting
aside Cuozzo, the Supreme Court also rejected this type of
statutory interpretation in Briscoe v. Bell, 432 U.S. 404
(1977).
    Briscoe involved the Voting Rights Act, which allowed
the Attorney General to determine whether “the precondi-
tions for application of the Act to particular jurisdictions
are met.” Id. at 407. The statute provided that “[a]
determination or certification of the Attorney General or
of the Director of the Census under this section . . . shall
not be reviewable in any court . . . .” Id. at 408. The D.C.
Circuit explained that “[i]t is . . . apparent that even
where the intent of Congress was to preclude judicial
review, a limited jurisdiction exists in the court to review
actions which on their face are plainly in excess of statu-
tory authority.” Id. (quoting Briscoe v. Levi, 535 F.2d
1259, 1265 (D.C. Cir. 1976)). The D.C. Circuit further
concluded that this statute barred judicial review of
substantive issues like “the actual computations made by
the Director of the Census,” but not “whether the Director
acted ‘consistent with the apparent meaning of the stat-
ute.’” Id. at 408–09 (quoting Briscoe, 535 F.2d at 1265).
The Supreme Court reversed, and found that “[s]ection
4(b) of the Voting Rights Act could hardly prohibit judicial
review in more explicit terms.” Id. at 409. The Court
stressed that “[t]he language is absolute on its face and
would appear to admit of no exceptions.” Id.
    Section 314(d) similarly prohibits review of “the de-
termination by the Director whether to institute an inter
8                          WI-FI ONE, LLC   v. BROADCOM CORP.

partes review.” Like the statute in Briscoe, the language
is absolute and provides no exceptions. Nevertheless, the
majority concludes that “[t]he timely filing of a petition
under § 315(b) is a condition precedent to the Director’s
authority to act.” Maj. Op. at 20 (emphasis added). Like
the D.C. Circuit in Briscoe, the majority attempts to
distinguish between “a decision of the Board made within
its jurisdiction” and “an order of the Board made in excess
of its delegated powers.” Briscoe, 535 F.2d at 1264. The
Supreme Court rejected this reasoning, and we should
too.
     Nor does the phrase “under this section” in § 314(d)
limit the bar on judicial review to only a subset of re-
quirements for institution. This court’s majority opinion
finds that § 314(d) does not bar review of timeliness
because the phrase “under this section” “limits the reach
of § 314(d) to the determination by the Director whether
to institute IPR as set forth in § 314.” Maj. Op. at 15
(emphasis added). But to be clear, the phrase “under this
section” simply refers to the fact that inter partes review
is instituted under § 314. The phrase does not limit the
bar on judicial review to the Director’s assessment of the
criteria under § 314. Indeed, Cuozzo foreclosed this
reading by holding that the bar on judicial review extends
to the Director’s assessment of the requirements under
§ 312, which is plainly a different statutory section than
§ 314. 136 S. Ct. at 2141.
                            II
    The plain language of § 314(d) should lead us to con-
clude that Congress intended to preclude judicial review
of whether IPR petitions are timely filed. To the extent
the statute is unclear, the history of the AIA dispels any
doubt that § 314(d) bars judicial review of issues like
timeliness and the identity of real parties in interest.
    The difference between § 314(d) and the bar on judi-
cial review for reexaminations confirms that Congress
WI-FI ONE, LLC   v. BROADCOM CORP.                        9

intended to broadly prohibit review of IPR institution
decisions. “[A] change in phraseology” in the statute
“creates a presumption of a change in intent.” Crawford
v. Burke, 195 U.S. 176, 190 (1904). And it is unlikely that
Congress would enact a statutory provision using differ-
ent language “without thereby intending a change of
meaning.” Id.; see also Merrill Lynch, Pierce, Fenner &
Smith Inc. v. Manning, 136 S. Ct. 1562, 1578 (2016)
(Thomas, J., concurring) (“[W]hen Congress enacts a
statute that uses different language from a prior statute,
we normally presume that Congress did so to convey a
different meaning.”).
       Even before the AIA, third-parties could seek admin-
istrative patent cancellation through reexamination.
When the PTO receives a request for reexamination, the
Director must determine whether the request raises a
substantial new question of patentability. And 35 U.S.C.
§ 303(c) provides that, “[a] determination by the Director
. . . that no substantial new question of patentability has
been raised will be final and nonappealable.” 1 According-
ly, the statute specifically bars review of the narrow issue
of whether the request raises a “substantial new question
of patentability.” Id. The statute does not bar review of
the entire decision to initiate reexamination.
    In stark contrast, Congress used markedly different
language for inter partes review and post-grant review
proceedings. Instead of barring review of the Director’s

    1 This was similarly true under the old 35 U.S.C.
§ 312(c) (2006), governing inter partes reexamination,
which barred appeal of “[a] determination by the Director
pursuant to subsection (a),” i.e., the determination that “a
substantial new question of patentability affecting any
claim of the patent concerned is raised by the request.” 35
U.S.C. § 312(a) (2006).
10                          WI-FI ONE, LLC   v. BROADCOM CORP.

determination of a specific issue, § 314(d) and 35 U.S.C.
§ 324(e) broadly prohibit review of the Director’s “deter-
mination . . . whether to institute” review. Accordingly,
these statutes identify a specific action by the Director,
not tied to the resolution of a specific issue such as sub-
stantial new question of patentability. Such linguistic
differences are particularly significant because the AIA
retained § 303(c), with its different language, with respect
to reexaminations.
                             III
    Even if we followed the majority’s approach and tried
to parse out which requirements for institution are barred
from judicial review under § 314, it still makes no sense to
distinguish § 315 from §§ 311–314. The assumption that
§ 315 is less closely related to § 314 than the institution
criteria of §§ 311–313, see Maj. Op. at 18–19, is simply
incorrect. For example, § 312(a)(1) and § 312(a)(2) relate
to the payment of fees and identification of real parties in
interest, which the majority agrees cannot be appealed.
These issues, however, bear the same relation to the
institution decision as the inquiry under § 315.
    Under § 315(b), the Director cannot institute review if
the petition was filed more than one year after the peti-
tioner or its real party in interest was served with a com-
plaint alleging infringement. And petitioners have the
onus to identify all real parties in interest under
§ 312(a)(2), which states that a petition “may be consid-
ered only if . . . the petition identifies all real parties in
interest.” Based on the petitioner’s disclosure, the Direc-
tor can assess whether any of the petitioner’s real parties
in interest was served with a complaint more than one
year before the petition. Thus, § 312(a)(2) is part and
parcel of the timeliness inquiry under § 315.
    The majority tries to distinguish between the real
party in interest inquiry under § 312(a)(2) and § 315(b).
Specifically, the majority notes that “if a petition fails to
WI-FI ONE, LLC   v. BROADCOM CORP.                        11

identify all real parties in interest under § 312(a)(2), the
Director can, and does, allow the petitioner to add a real
party in interest.” Maj. Op. at 22 n.11. By contrast, a
petition that is time-barred under § 315 cannot be recti-
fied. Id.
    To illustrate why this distinction is flawed, suppose
that a patent owner argues that an unidentified third-
party, who has not been sued for infringement, is a real
party in interest to the petition. The Director disagrees
with the patent owner and institutes review. No one
disputes that the Director’s decision on real party in
interest is unreviewable in this scenario. Now suppose
the Director makes the exact same determination, but
with respect to a third-party who was sued more than one
year before the petition was filed. Even though the Direc-
tor is making the same factual inquiry, his determination
now becomes reviewable because it implicates the time-
bar. This result is illogical. The same inquiry does not
become more or less “closely related” to the institution
determination simply because the results of that inquiry
have different consequences.
    The facts of this appeal underscore why timeliness
under § 315 is as closely related to the institution decision
as the requirements under § 312. Wi-Fi One does not
contend that Broadcom itself was served with a complaint
more than one year before its petition. Rather, Wi-Fi One
asserts that various defendants in a 2010 Texas lawsuit
were unidentified real parties in interest to Broadcom’s
petition. On remand, the panel must determine whether
the Board properly resolved which parties constitute a
real party in interest under § 312(a)(2). Even Wi-Fi One
recognizes that this inquiry is highly fact dependent, as it
sought broad-ranging discovery into agreements, pay-
ments, and e-mail communications in the proceedings
below. But giving the Board wide discretion on such
preliminary determinations is what enables IPRs to
function as an efficient method of resolving validity
12                         WI-FI ONE, LLC   v. BROADCOM CORP.

issues. Congress would not have “giv[en] the Patent
Office significant power to revisit and revise earlier
patent grants . . . if it had thought that the agency’s final
decision could be unwound under some minor statutory
technicality related to its preliminary decision to institute
inter partes review.” Cuozzo, 136 S. Ct. at 2139–40.
    Vacating the Board’s invalidity decision on the basis
of threshold questions like timeliness or real parties in
interest will squander the time and resources spent
adjudicating the actual merits of the petition. This is
counter to the AIA’s purpose of “providing quick and cost
effective alternatives to litigation.” H.R. Rep. No. 112-98,
pt. 1, at 48 (2011). Congress recognized this issue, so it
prohibited this court from reviewing the Board’s institu-
tion decision. It is not our prerogative to second-guess
that policy decision, nor should we rely on tenuous statu-
tory interpretations to undermine it.
                             IV
   Because we do not have jurisdiction to review the
Board’s determination that Broadcom’s petition was
timely filed, I respectfully dissent.
