CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR 

THE FEDERAL CIRCUIT 

No. 18–916. Argued December 9, 2019—Decided April 20, 2020 

Inter partes review is an administrative process that permits a patent 

challenger to ask the U. S. Patent and Trademark Office to reconsider 

the validity of earlier granted patent claims. For inter partes review 

to proceed, the agency must agree to institute review. See 35 U. S. C. 

§314. Among other conditions set by statute, if a request comes more

than a year after suit against the requesting party for patent infringement, “[a]n inter partes review may not be instituted.” §315(b). The 

agency’s “determination . . . whether to institute an inter partes review 

under this section shall be final and nonappealable.” §314(d). 

Entities associated with petitioner Thryv, Inc. sought inter partes 

review of a patent owned by respondent Click-to-Call Technologies, 

LP. Click-to-Call countered that the petition was untimely under 

§315(b). The Patent Trial and Appeal Board (Board) disagreed and 

instituted review. After proceedings on the merits, the Board issued a

final written decision reiterating its §315(b) decision and canceling 13 

of the patent’s claims as obvious or lacking novelty. Click-to-Call appealed the Board’s §315(b) determination. Treating the Board’s application of §315(b) as judicially reviewable, the Court of Appeals concluded that the petition was untimely, vacated the Board’s decision, 

and remanded with instructions to dismiss. 

Held: Section 314(d) precludes judicial review of the agency’s application 

of §315(b)’s time prescription. Pp. 6–14.

(a) A party generally cannot contend on appeal that the agency 

should have refused “to institute an inter partes review.” §314(d). 

That follows from §314(d)’s text and Cuozzo Speed Technologies, LLC 

v. Lee, 579 U. S. ___. In Cuozzo, this Court explained that §314(d) 

“preclud[es] review of the Patent Office’s institution decisions”—at

Syllabus 

least “where the grounds for attacking the decision to institute inter

partes review consist 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., at ___. Pp. 6–7.

(b) The question here is whether a challenge based on §315(b) ranks 

as an appeal of the agency’s decision “to institute an inter partes review.” §314(d). There is no need to venture beyond Cuozzo’s holding

that §314(d) bars review at least of matters “closely tied to the application and interpretation of statutes related to” the institution decision, 579 U. S., at ___. A §315(b) challenge easily meets that measurement. Section 315(b), setting forth a circumstance in which “[a]n inter

partes review may not be instituted,” expressly governs institution and 

nothing more. Pp. 7–8.

(c) This conclusion is strongly reinforced by the statute’s purpose 

and design. Congress designed inter partes review to weed out bad 

patent claims efficiently. Allowing §315(b) appeals, however, would

unwind agency proceedings determining patentability and leave bad 

patents enforceable. Pp. 8–10. 

(d) In Click-to-Call’s view, §314(d)’s bar on judicial review is limited

to the agency’s threshold determination under §314(a) of the question

whether the petitioner has a reasonable likelihood of prevailing. 

Cuozzo is fatal to that interpretation, for the Court in that case held

unreviewable the agency’s application of a provision other than 

§314(a). Contrary to Click-to-Call’s contention, §314(d)’s text does not 

limit the review bar to §314(a). Rather than borrowing language from 

related provisions that would have achieved Click-to-Call’s preferred 

meaning, Congress used broader language in §314(d). Click-to-Call 

also insists that Congress intended judicial supervision of the agency’s 

application of §315(b), but the statute instead reflects a choice to entrust that issue to the agency. Finally, SAS Institute Inc. v. Iancu, 584 

U. S. ___, offers Click-to-Call no assistance. Unlike the appeal held 

reviewable in SAS Institute, Click-to-Call’s appeal challenges not the 

manner in which the agency’s review proceeds once instituted, but 

whether the agency should have instituted review at all. Pp. 10–13.

(e) Click-to-Call argues in the alternative that its §315(b) objection 

is authorized as an appeal from the Board’s final written decision, 

which addressed the §315(b) issue. Even labeled that way, Click-toCall’s appeal is still barred by §314(d) because Click-to-Call’s contention remains, essentially, that the agency should have refused to institute inter partes review. P. 14.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 

APPEALS FOR THE FEDERAL CIRCUIT 

[April 20, 2020] 

JUSTICE GINSBURG delivered the opinion of the Court.* 

Inter partes review is an administrative process in which

a patent challenger may ask the U. S. Patent and Trademark Office (PTO) to reconsider the validity of earlier

granted patent claims. This case concerns a statutorily prescribed limitation of the issues a party may raise on appeal 

from an inter partes review proceeding.

When presented with a request for inter partes review,

the agency must decide whether to institute review. 35 

U. S. C. §314. Among other conditions set by statute, if the 

request comes more than a year after suit against the requesting party for patent infringement, “[a]n inter partes

review may not be instituted.” §315(b). “The determination 

by the [PTO] Director whether to institute an inter partes 

review under this section shall be final and nonappealable.” 

§314(d).†

2 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

Opinion of the Court 

response to a petition from Thryv, Inc., resulting in the cancellation of several patent claims. Patent owner Click-toCall Technologies, LP, appealed, contending that Thryv’s 

petition was untimely under §315(b).

The question before us: Does §314(d)’s bar on judicial review of the agency’s decision to institute inter partes review

preclude Click-to-Call’s appeal? Our answer is yes. The 

agency’s application of §315(b)’s time limit, we hold, is 

closely related to its decision whether to institute inter 

partes review and is therefore rendered nonappealable by

§314(d). 

I 

The Patent and Trademark Office has several ways “to

reexamine—and perhaps cancel—a patent claim that it had 

previously allowed.” Cuozzo Speed Technologies, LLC v. 

Lee, 579 U. S. ___, ___ (2016) (slip op., at 3). Congress established the procedure at issue here, inter partes review,

in the Leahy-Smith America Invents Act (AIA), 125 Stat.

284, enacted in 2011. See 35 U. S. C. §311 et seq. Inter 

partes review allows third parties to challenge patent

claims on grounds of invalidity specified by statute. 

§311(b).

For inter partes review to proceed, the agency must agree

to institute review. §314. Any person who is not the patent’s owner may file a petition requesting inter partes review. §311(a). The patent owner may oppose institution of 

inter partes review, asserting the petition’s “failure . . . to 

meet any requirement of this chapter.” §313.

The AIA sets out prerequisites for institution. Among

them, “[t]he Director may not authorize an inter partes review to be instituted unless the Director determines . . . 

that there is a reasonable likelihood that the petitioner 

would prevail with respect to at least 1 of the claims challenged in the petition.” §314(a). Most pertinent to this case, 
 

 

Cite as: 590 U. S. ____ (2020) 3 

Opinion of the Court 

“[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 

infringement of the patent.” §315(b).

After receiving the petition and any response, the PTO 

“Director shall determine whether to institute an inter 

partes review under this chapter.” §314(b). The Director 

has delegated institution authority to the Patent Trial and

Appeal Board (Board). 37 CFR §42.4(a) (2019). As just 

noted, the federal agency’s “determination . . . whether to 

institute an inter partes review under this section” is “final

and nonappealable.” 35 U. S. C. §314(d). 

Upon electing to institute inter partes review, the Board

conducts a proceeding to evaluate the challenged claims’ validity. See §316. At the conclusion of the proceeding—if 

review “is instituted and not dismissed”—the Board “issue[s] a final written decision with respect to the patentability of ” the challenged claims. §318(a). “A party dissatisfied with the final written decision . . . may appeal the 

decision” to the Court of Appeals for the Federal Circuit.

§319. 

II 

Respondent Click-to-Call owns a patent relating to a 

technology for anonymous telephone calls, U. S. Patent No.

5,818,836 (’836 patent). In 2013, petitioner Thryv sought

inter partes review, challenging several of the patent’s 

claims.1 

In opposition, Click-to-Call urged that §315(b) barred institution of inter partes review because Thryv filed its petition too late. Click-to-Call pointed to an infringement suit 

—————— 1More precisely, the petition was filed by four companies, including 

YellowPages.com, LLC, and Ingenio, LLC. Through “a series of mergers, 

sales, and name changes,” both became Thryv. Brief for Petitioner 8. 

For simplicity, we refer to Thryv and its predecessor entities as “Thryv.” 
 

 

4 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

Opinion of the Court 

filed in 2001, which ended in a voluntary dismissal without 

prejudice.2 In Click-to-Call’s view, that 2001 suit started 

§315(b)’s one-year clock, making the 2013 petition

untimely.

The Board disagreed. Section 315(b) did not bar the institution of inter partes review, the Board concluded, because a complaint dismissed without prejudice does not

trigger §315(b)’s one-year limit. Finding no other barrier to 

institution, the Board decided to institute review. After 

proceedings on the merits, the Board issued a final written 

decision reiterating its rejection of Click-to-Call’s §315(b) 

argument and canceling 13 of the patent’s claims as obvious 

or lacking novelty.

Click-to-Call appealed, challenging only the Board’s determination that §315(b) did not preclude inter partes review. The Court of Appeals dismissed the appeal for lack of 

jurisdiction, agreeing with Thryv and the Director (who intervened on appeal) that §314(d)’s bar on appeal of the institution decision precludes judicial review of the agency’s 

application of §315(b). Citing our intervening decision in 

Cuozzo, see infra, at 6–7, we granted certiorari, vacated the

judgment, and remanded. Click-to-Call Technologies, LP v. 

Oracle Corp., 579 U. S. ___ (2016). On remand, the Court 

of Appeals again dismissed the appeal on the same ground.

Thereafter, in another case, the en banc Federal Circuit 

held that “time-bar determinations under §315(b) are appealable” notwithstanding §314(d). Wi-Fi One, LLC v. 

Broadcom Corp., 878 F. 3d 1364, 1367 (2018). The majority

opinion construed §314(d)’s reference to the determination

whether to institute inter partes review “under this section” 

—————— 2The 2001 suit was brought by Inforocket.Com, Inc.—then the exclusive licensee of the ’836 patent—against Keen, Inc. See Inforocket.Com, 

Inc. v. Keen, Inc., No. 1:01–cv–05130 (SDNY). While the suit was pending, Keen acquired Inforocket and the District Court dismissed the suit

without prejudice. By the time of the inter partes review petition, Keen 

had become Ingenio (now Thryv).

Opinion of the Court 

as trained on the likelihood-of-success requirement stated 

in §314(a). Id., at 1372. The §315(b) timeliness 

determination, the majority concluded, “is not ‘closely

related’ to the institution decision addressed in §314(a).” 

Id., at 1374 (quoting Cuozzo, 579 U. S., at ___ (slip op., at 

12)). The majority therefore held that for §315(b) appeals,

§314(d) does not displace the usual presumption favoring

judicial review of agency action. Wi-Fi One, 878 F. 3d, at 

1374–1375. In a concurring opinion, Judge O’Malley 

emphasized a “simpler” basis for the same conclusion. Id., 

at 1375. In her view, §314(d) shields from review only the 

agency’s assessment of a petition’s “substantive adequacy,” 

not questions about the agency’s “authority to act.” Id., at 

1376. 

Judge Hughes, joined by Judges Lourie, Bryson, and Dyk,

dissented, expressing a position that today’s dissent 

characterizes as “extraordinary.” Post, at 6. Those judges

concluded that §314(d) conveys Congress’ “clear and

unmistakable” “intent to prohibit judicial review of the

Board’s [inter partes review] institution decision.” Wi-Fi 

One, 878 F. 3d, at 1378. That prohibition applies to §315(b)

issues, the Federal Circuit dissenters maintained, because 

§315(b) “describes when an [inter partes review] may be 

‘instituted.’” Id., at 1377, 1378–1379 (quoting §315(b)). 

In light of its en banc decision in Wi-Fi One, the Court of 

Appeals granted panel rehearing in this case. Treating the 

Board’s application of §315(b) as judicially reviewable, the 

panel’s revised opinion held that the Board erred by instituting review. The petition for inter partes review here was

untimely, the Court of Appeals held, because the 2001 infringement complaint, though dismissed without prejudice,

started the one-year clock under §315(b).3 The court therefore vacated the Board’s final written decision, which had

Opinion of the Court 

invalidated 13 of Click-to-Call’s claims for want of the requisite novelty and nonobviousness, and remanded with instructions to dismiss. 

We granted certiorari to resolve the reviewability issue,

587 U. S. ___ (2019), and now vacate the Federal Circuit’s 

judgment and remand with instructions to dismiss the appeal for lack of appellate jurisdiction. 

III 

A 

To determine whether §314(d) precludes judicial review

of the agency’s application of §315(b)’s time prescription, we 

begin by defining §314(d)’s scope. Section 314(d)’s text renders “final and nonappealable” the “determination by the 

Director whether to institute an inter partes review under 

this section.” §314(d) (emphasis added). That language indicates that a party generally cannot contend on appeal

that the agency should have refused “to institute an inter

partes review.”

We held as much in Cuozzo. There, a party contended on 

appeal that the agency should have refused to institute inter partes review because the petition failed §312(a)(3)’s requirement that the grounds for challenging patent claims 

must be identified “with particularity.” 579 U. S., at ___ 

(slip op., at 6) (internal quotation marks omitted). This 

“contention that the Patent Office unlawfully initiated its 

agency review is not appealable,” we held, for “that is what 

§314(d) says.” Id., at ___ (slip op., at 7). Section 314(d), we 

explained, “preclud[es] review of the Patent Office’s institution decisions” with sufficient clarity to overcome the 

—————— 

ting en banc had considered and agreed with the panel majority’s conclusion that a complaint voluntarily dismissed without prejudice can trigger 

§315(b)’s time bar. Click-to-Call Technologies, LP v. Ingenio, Inc., 899 

F. 3d 1321, 1328, n. 3 (CA Fed. 2018). On that issue, Judge Taranto issued a concurring opinion, id., at 1343–1347, and Judge Dyk, joined by

Judge Lourie, issued a dissenting opinion, id., at 1350–1355. That question is outside the scope of our review. 
 

 

 

Cite as: 590 U. S. ____ (2020) 7 

Opinion of the Court 

“‘strong presumption’ in favor of judicial review.” Id., at 

___–___ (slip op., at 9–11) (quoting Mach Mining, LLC v. 

EEOC, 575 U. S. 480, 486 (2015)). See Cuozzo, 579 U. S., 

at ___– ___ (slip op., at 9–11) (finding “‘clear and convincing’ 

indications . . . that Congress intended to bar review” (quoting Block v. Community Nutrition Institute, 467 U. S. 340, 

349–350 (1984))).

We reserved judgment in Cuozzo, however, on whether 

§314(d) would bar appeals reaching well beyond the decision to institute inter partes review. 579 U. S., at ___ (slip 

op., at 11). We declined to “decide the precise effect of 

§314(d) on,” for example, “appeals that implicate constitutional questions.” Ibid. Instead, we defined the bounds of 

our holding this way: “[O]ur interpretation applies where 

the grounds for attacking the decision to institute inter 

partes review consist 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.” 

Ibid. 

B 

We therefore ask whether a challenge based on §315(b) 

ranks as an appeal of the agency’s decision “to institute an

inter partes review.” §314(d). We need not venture beyond 

Cuozzo’s holding that §314(d) bars review at least of matters “closely tied to the application and interpretation of 

statutes related to” the institution decision, 579 U. S., at 

___ (slip op., at 11), for a §315(b) challenge easily meets that 

measurement. 

Section 315(b)’s time limitation is integral to, indeed a 

condition on, institution. After all, §315(b) sets forth a circumstance in which “[a]n inter partes review may not be

instituted.” Even Click-to-Call and the Court of Appeals 

recognize that §315(b) governs institution. See Brief for Respondent Click-to-Call 1 (§315(b) is “a clear limit on the

Board’s institution authority”); Wi-Fi One, 878 F. 3d, at 
 

 

8 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

Opinion of the Court 

1373 (“§315(b) controls the Director’s authority to institute 

[inter partes review]”).

Because §315(b) expressly governs institution and nothing more, a contention that a petition fails under §315(b) is 

a contention that the agency should have refused “to institute an inter partes review.” §314(d). A challenge to a petition’s timeliness under §315(b) thus raises “an ordinary 

dispute about the application of ” an institution-related 

statute. Cuozzo, 579 U. S., at ___ (slip op., at 7). In this 

case as in Cuozzo, therefore, §314(d) overcomes the presumption favoring judicial review.4 

C 

The AIA’s purpose and design strongly reinforce our conclusion. By providing for inter partes review, Congress, 

concerned about overpatenting and its diminishment of 

competition, sought to weed out bad patent claims efficiently. See id., at ___ (slip op., at 8); H. R. Rep. No. 112–

98, pt. 1, p. 40 (2011) (“The legislation is designed to establish a more efficient and streamlined patent system that

will improve patent quality and limit unnecessary and 

counterproductive litigation costs.”).5 

—————— 4We do not decide whether mandamus would be available in an extraordinary case. Cf. Cuozzo Speed Technologies, LLC v. Lee, 579 U. S. 

___, ___–___, n. 5 (2016) (ALITO, J., concurring in part and dissenting in 

part) (slip op., at 5–6, n. 5). 5The dissent acknowledges that “Congress authorized inter partes review to encourage further scrutiny of already issued patents.” Post, at 

14. Yet the dissent, despite the Court’s decision upholding the constitutionality of such review in Oil States Energy Services, LLC v. Greene’s 

Energy Group, LLC, 584 U. S. ___ (2018), appears ultimately to urge that 

Congress lacks authority to permit second looks. Patents are property, 

the dissent several times repeats, and Congress has no prerogative to 

allow “property-taking-by-bureaucracy.” Post, at 1, 18–21. But see Oil 

States, 584 U. S., at ___ (slip op., at 7) (“patents are public franchises”

(internal quotation marks omitted)). The second look Congress put in 

place is assigned to the very same bureaucracy that granted the patent 

in the first place. Why should that bureaucracy be trusted to give an 
Cite as: 590 U. S. ____ (2020) 9 

Opinion of the Court 

Allowing §315(b) appeals would tug against that objective, wasting the resources spent resolving patentability 

and leaving bad patents enforceable. A successful §315(b) 

appeal would terminate in vacatur of the agency’s decision; 

in lieu of enabling judicial review of patentability, vacatur

would unwind the agency’s merits decision. See Cuozzo, 

579 U. S., at ___ (slip op., at 8). And because a patent owner 

would need to appeal on §315(b) untimeliness grounds only 

if she could not prevail on patentability, §315(b) appeals 

would operate to save bad patent claims. This case illustrates the dynamic. The agency held Click-to-Call’s patent

claims invalid, and Click-to-Call does not contest that holding. It resists only the agency’s institution decision, mindful that if the institution decision is reversed, then the 

agency’s work will be undone and the canceled patent 

claims resurrected. 

Other features of the statutory design confirm that Congress prioritized patentability over §315(b)’s timeliness requirement. A petitioner’s failure to satisfy §315(b) does not

prevent the agency from conducting inter partes review of

the challenged patent claims; the agency can do so at another petitioner’s request. §311(a). Nor does failure to satisfy §315(b) prevent the original initiator from participating

on the merits; the §315(b)-barred party can join a proceeding initiated by another petitioner. §315(b), (c). And once 

inter partes review is instituted, the agency may issue a final written decision even “[i]f no petitioner remains in the 

inter partes review.” §317(a). It is unsurprising that a statutory scheme so consistently elevating resolution of patentability above a petitioner’s compliance with §315(b) would 

exclude §315(b) appeals, thereby preserving the Board’s adjudication of the merits. 

—————— 

honest count on first view, but a jaundiced one on second look? See post, 

at 19–20. 
 

 

 

10 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

Opinion of the Court 

Judicial review of §315(b) rulings, moreover, would do little to serve other statutory goals. The purpose of §315(b), 

all agree, is to minimize burdensome overlap between inter 

partes review and patent-infringement litigation. Brief for 

Petitioner 24; Brief for Federal Respondent 36; Brief for Respondent Click-to-Call 37. Judicial review after the agency

proceedings cannot undo the burdens already occasioned.

Nor are §315(b) appeals necessary to protect patent claims

from wrongful invalidation, for patent owners remain free 

to appeal final decisions on the merits. §319. 

IV 

Click-to-Call advances a narrower reading of §314(d). In 

Click-to-Call’s view, which the dissent embraces, post, at 6– 

18, the bar on judicial review applies only to the agency’s 

threshold determination under §314(a) of the question

whether the petitioner has a reasonable likelihood of prevailing. Section 314(d) addresses the “determination by the 

Director whether to institute inter partes review under this 

section” (emphasis added), and, Click-to-Call maintains, 

§314(a) contains “the only substantive determination referenced in” the same section as §314(d). Brief for Respondent

Click-to-Call 16. This interpretation, Click-to-Call argues, 

supplies a clear rule consonant with the presumption favoring judicial review. Cf. supra, at 4–5 (Federal Circuit’s en 

banc Wi-Fi One decision). 

Cuozzo is fatal to Click-to-Call’s interpretation. Section 

314(d)’s review bar is not confined to the agency’s application of §314(a), for in Cuozzo we held unreviewable the 

agency’s application of §312(a)(3). 579 U. S., at ___–___ 

(slip op., at 7–8). Far from limiting the appeal bar to

§314(a) and “nothing else” as Click-to-Call urges, Brief for

Respondent 29, the Court’s opinion in Cuozzo explained

that the bar extends to challenges grounded in “statutes related to” the institution decision. 579 U. S., at ___ (slip op., 

at 11). 
Cite as: 590 U. S. ____ (2020) 11 

Opinion of the Court 

The text of §314(d) offers Click-to-Call no support. The 

provision sweeps more broadly than the determination 

about whether “there is a reasonable likelihood that the petitioner would prevail.” §314(a). Rather, it encompasses

the entire determination “whether to institute an inter 

partes review.” §314(d).

And §314(d) refers not to a determination under subsection (a), but to the determination “under this section.” That 

phrase indicates that §314 governs the Director’s institution of inter partes review. Titled “Institution of inter 

partes review,” §314 is the section housing the command to 

the Director to “determine whether to institute an inter 

partes review,” §314(b). Thus, every decision to institute is

made “under” §314 but must take account of specifications

in other provisions—such as the §312(a)(3) particularity requirement at issue in Cuozzo and the §315(b) timeliness requirement at issue here. Similar clarifying language recurs 

throughout the AIA. See, e.g., §315(c) (referring to the Director’s determination regarding “the institution of an inter 

partes review under section 314” (emphasis added)); §314(b) 

(referring to “a petition filed under section 311,” the section 

authorizing the filing of petitions (emphasis added));

§314(b)(1) (referring to “a preliminary response to the petition under section 313,” the section authorizing the filing of 

preliminary responses to petitions (emphasis added)). 

If Congress had intended Click-to-Call’s meaning, it had 

at hand readymade language from a precursor to §314(d):

“A determination by the Director under subsection (a) shall 

be final and non-appealable.” 35 U. S. C. §312(c) (2006 ed.) 

(emphasis added) (governing inter partes reexamination). 

Or Congress might have borrowed from a related provision:

“A determination by the Director pursuant to subsection (a) 

of this section that no substantial new question of patentability has been raised will be final and nonappealable.” 35 

U. S. C. §303(c) (emphasis added) (governing ex parte reex-

Opinion of the Court 

amination). Instead, Congress chose to shield from appellate review the determination “whether to institute an inter 

partes review under this section.” §314(d) (emphasis

added). That departure in language suggests a departure 

in meaning. See Henson v. Santander Consumer USA Inc., 

582 U. S. ___, ___ (2017) (slip op., at 6). 

Click-to-Call doubts that Congress would have limited 

the agency’s institution authority in §315(b) without ensuring judicial supervision. Congress entrusted the institution

decision to the agency, however, to avoid the significant

costs, already recounted, of nullifying a thoroughgoing determination about a patent’s validity. See supra, at 8–9. 

That goal—preventing appeals that would frustrate efficient resolution of patentability—extends beyond §314(a)

appeals.

Click-to-Call also contends that we adopted its interpretation of §314(d) in SAS Institute Inc. v. Iancu, 584 U. S. ___ 

(2018). Neither of our holdings in that case assists Clickto-Call, and both holdings remain governing law. SAS Institute first held that once the agency institutes an inter 

partes review, it must “resolve all of the claims in the case.” 

Id., at ___ (slip op., at 1). SAS Institute located that rule in 

§318(a), which requires the agency to decide “the patentability of any patent claim challenged by the petitioner.” 

Ibid. (emphasis in original; internal quotation marks omitted). SAS Institute next held that §314(d) did not bar judicial review of §318(a)’s application. Id., at ___–___ (slip op., 

at 12–14). Our decision explained that “nothing in §314(d) 

or Cuozzo withdraws our power to ensure that an inter 

partes review proceeds in accordance with the law’s demands.” Id., at ___ (slip op., at 14). That reviewability holding is inapplicable here, for Click-to-Call’s appeal challenges not the manner in which the agency’s review

“proceeds” once instituted, but whether the agency should 

have instituted review at all. 
Cite as: 590 U. S. ____ (2020) 13 

Opinion of the Court 

Click-to-Call homes in on a single sentence from SAS Institute’s reviewability discussion: “Cuozzo concluded that 

§314(d) precludes judicial review only of the Director’s ‘initial determination’ under §314(a) that ‘there is a “reasonable likelihood” that the claims are unpatentable on the 

grounds asserted’ and review is therefore justified.” Id., at 

___ (slip op., at 13) (quoting Cuozzo, 579 U. S., at ___ (slip 

op., at 9)). But that sentence’s account of Cuozzo is incomplete. Recall that Cuozzo itself applied §314(d)’s appeal bar 

to a challenge on grounds other than §314(a). See supra, at 

10. To understand how far beyond §314(a) the bar on judicial review extends, we look to the statute and Cuozzo; for 

the reasons stated above, they establish that §314(d) bars 

challenges resting on §315(b).6 

—————— 6Defending Click-to-Call’s interpretation, the dissent takes a view of

our precedent that neither Click-to-Call nor the Federal Circuit advances. See post, at 15–18. The dissent does not consider itself bound 

by Cuozzo’s conclusion that §314(d) bars appeal 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,” 579 U. S., at

___ (slip op., at 11). According to the dissent, that statement is dicta 

later repudiated in SAS Institute Inc. v. Iancu, 584 U. S. ___ (2018).

But Cuozzo concerned an appeal resting on a “related statutory section”: §312(a)(3). 579 U. S., at ___ (slip op., at 7). That §312(a)(3) 

challenge was tied to institution, the Court explained, for two reasons: 

first, because it “attack[ed] a ‘determination . . . whether to institute’ 

review,” id., at ___–___ (slip op., at 7–8); second, because the §312(a)(3)

challenge was related to invoking §314(a)’s condition on institution, id., 

at ___ (slip op., at 12). Cuozzo’s recognition that §314(d) can bar challenges rooted in provisions other than §314(a) was hardly “dicta,” post, 

at 16—it was the Court’s holding. And SAS Institute purported to adhere 

to Cuozzo, not to overrule it. 584 U. S., at ___–___ (slip op., at 13–14). 

The Court in SAS Institute said, specifically, that it discerned “nothing 

in . . . Cuozzo” inconsistent with its conclusion. Id., at ___ (slip op.,

at 14).

We do not so lightly treat our determinations as dicta and our decisions

as overruling others sub silentio. Nor can we countenance the dissent’s 

dangerous insinuation that today’s decision is not “really” binding precedent. Post, at 17–18 (“[W]ho can say?”); post, at 18 (“Litigants and lower

Click-to-Call presses an alternative reason why the

Board’s ruling on its §315(b) objection is appealable. The 

Board’s final written decision addressed the §315(b) issue,

so Click-to-Call argues that it may appeal under §319, 

which authorizes appeal from the final written decision. 

But even labeled as an appeal from the final written decision, Click-to-Call’s attempt to overturn the Board’s §315(b) 

ruling is still barred by §314(d). Because §315(b)’s sole office is to govern institution, Click-to-Call’s contention remains, essentially, that the agency should have refused to

institute inter partes review. As explained, §314(d) makes

that contention unreviewable.

SUPREME COURT OF THE UNITED STATES 

No. 18–916 

THRYV, INC., FKA DEX MEDIA, INC., PETITIONER v. 

CLICK-TO-CALL TECHNOLOGIES, LP, ET AL. 

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 

APPEALS FOR THE FEDERAL CIRCUIT 

[April 20, 2020] 

JUSTICE GORSUCH, with whom JUSTICE SOTOMAYOR joins

as to Parts I, II, III, and IV, dissenting. 

Today the Court takes a flawed premise—that the Constitution permits a politically guided agency to revoke an

inventor’s property right in an issued patent—and bends it 

further, allowing the agency’s decision to stand immune

from judicial review. Worse, the Court closes the courthouse not in a case where the patent owner is merely unhappy with the merits of the agency’s decision but where 

the owner claims the agency’s proceedings were unlawful 

from the start. Most remarkably, the Court denies judicial 

review even though the government now concedes that the

patent owner is right and this entire exercise in propertytaking-by-bureaucracy was forbidden by law. 

It might be one thing if Congress clearly ordained this 

strange result. But it did not. The relevant statute, the 

presumption of judicial review, and our precedent all point 

toward allowing, not forbidding, inventors their day in 

court. Yet, the Court brushes past these warning signs and, 

in the process, carries us another step down the road of ceding core judicial powers to agency officials and leaving the 

disposition of private rights and liberties to bureaucratic 

mercy. 
 

 

 

2 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

I 

Our story stretches back to the 1990s, when Stephen DuVal invented a system for anonymizing telephone calls. Believing in the promise of his idea, Mr. DuVal hired an attorney to secure a patent and sought avenues to bring his

invention to market. Initially, both efforts met with success. In 1998, Mr. DuVal was awarded a U. S. Patent, 

which he licensed to a company called InfoRocket.com, Inc. 

But problems soon emerged. In 2001, InfoRocket accused 

Ingenio, Inc., a predecessor of today’s petitioner Thryv, Inc.,

of infringing Mr. DuVal’s patent. The case carried on in 

federal district court for more than a year before InfoRocket 

and Ingenio decided to merge. The companies then jointly

persuaded the court to dismiss InfoRocket’s lawsuit without 

prejudice.

Still, the quiet did not last long. Following the merger,

the surviving entity—for simplicity, call it Thryv—sought

to turn the tables on Mr. DuVal by asking the Patent Office

to reconsider the validity of his patent in an ex parte reexamination. That agency-led process dragged on for four 

more years, and ended with a mixed verdict: The Patent 

Office canceled a few claims, but amended others and permitted Mr. DuVal to add some new ones too. 

Even the ex parte reexamination wasn’t enough to put 

the parties’ disputes to rest. During the reexamination, 

Thryv terminated its license with Mr. DuVal and stopped 

paying him royalties. But it seems that Thryv continued

using the patented technology all the same. So Mr. Duval 

transferred his patent to respondent Click-to-Call Technologies LP (CTC), which swiftly took the patent back to court.

CTC noted that Thryv couldn’t exactly plead ignorance

about this patent, given that the company or its predecessors had previously licensed the patent, been sued for infringing it, and asked the Patent Office to reexamine it. 

When it came to Mr. DuVal’s patent, CTC alleged, Thryv 
 

Cite as: 590 U. S. ____ (2020) 3 

GORSUCH, J., dissenting 

had done just about everything one can do to a patent except invent it. 

Thryv responded by opening another new litigation front

of its own. One year after CTC filed its federal lawsuit, 

Thryv lodged another administrative petition with the Patent Office, this time seeking inter partes review. Echoing

some of the same arguments that led to its push for an 

ex parte administrative reexamination nine years earlier, 

and adding other arguments too, Thryv (again) asked the 

agency to cancel Mr. DuVal’s patent on the grounds that it 

lacked novelty and was obvious. At the same time, Thryv

sought to stay proceedings in CTC’s infringement suit. 

Thryv argued that the district court should defer to the 

newly initiated inter partes review. Like many district 

courts facing the prospect of parallel administrative proceedings, this one obliged. 

Why at this late hour did Thryv prefer to litigate before 

the agency rather than a federal district court? The 

agency’s ex parte reexamination years earlier hadn’t helped 

Thryv much. But since then, Congress had adopted the

Leahy-Smith America Invents Act (AIA), 35 U. S. C. §100 

et seq. That law created the inter partes review process,

which provides a number of benefits to accused infringers

such as Thryv. Like federal court litigation, inter partes 

review holds the advantage of allowing a private party attacking a patent’s validity to participate in adversarial proceedings, rather than rely on the agency to direct its own 

investigation as it does in ex parte reexamination. Compare 35 U. S. C. §316 with §§302, 304, 305. Inter partes 

review also allows a party challenging a patent all manner 

of discovery, including depositions and the presentation of 

expert testimony. §316; 37 CFR §§42.51–42.65 (2019). At 

the same time, the burden of proof is lower—requiring challengers like Thryv to prove unpatentability only by a preponderance of the evidence, §316(e), rather than under the 

clear and convincing standard that usually applies in court. 
 

4 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

Microsoft Corp. v. i4i L. P., 564 U. S. 91 (2011). Perhaps 

most appealing, proceedings take place before the Patent

Trial and Appeal Board, rather than in an Article III court,

so there is no jury trial before a tenure-protected judge, only

a hearing before a panel of agency employees.

Some say the new regime represents a particularly

efficient new way to “kill” patents. Certainly, the numbers 

tell an inviting story for petitioners like Thryv. In approximately 80% of cases reaching a final decision, the 

Board cancels some or all of the challenged claims.

Patent Trial and Appeal Board, Trial Statistics 10 (Feb.

2020), https://www.uspto.gov/sites/default/files/documents/

Trial_Statistics_2020_02_29.pdf. The Board has been busy,

too, instituting more than 800 of these new proceedings 

every year. See id., at 6. 

Still, Thryv faced a hurdle. Inter partes review “may not 

be instituted” based on an administrative petition filed

more than a year after “the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent” in federal court. 35 

U. S. C. §315(b). So, while Congress sought to move many 

cases out of court and into its new administrative process, 

it thought patent owners who have already endured long

challenges in court shouldn’t have to face another layer of

administrative review. After all, some repose is due inventors. Patents typically last 20 years; what happens to the 

incentive to invent if litigation over them lasts even longer 

(as it has for Mr. DuVal)? By anyone’s estimation, too, 

§315(b)’s time bar was sure to pose a special problem for 

Thryv. Yes, Thryv had petitioned for inter partes review

one year after being served with CTC’s complaint. But 

nearly 12 years had passed since Thryv’s predecessor and 

privy first found itself on the business end of a lawsuit alleging that it had infringed Mr. DuVal’s patent. 

Despite this apparently fatal defect, the Board plowed 
 

Cite as: 590 U. S. ____ (2020) 5 

GORSUCH, J., dissenting 

ahead anyway. No one could dispute that Thryv’s predecessor and privy had been “served with a complaint alleging

infringement of the patent” more than a decade earlier. But 

that complaint didn’t count, the Board declared, because it 

was dismissed without prejudice. The Board cited nothing 

in §315(b) suggesting this distinction makes a difference

under the statute’s plain terms. Instead, the Board tiptoed 

past the problem and proceeded to invalidate almost all of 

the patent claims before it, even those the Patent Office itself had affirmed in its own ex parte proceeding years before. No doubt this was exactly what Thryv hoped for in its

second bite at the administrative apple. 

Thryv’s victory may have taken years to achieve, but it

didn’t seem calculated to last long. Predictably, CTC appealed the Board’s interpretation of §315(b) to the Federal 

Circuit. And just as unsurprisingly, the court held that dismissed complaints do count as complaints, so Thryv’s inter

partes administrative challenge was time barred from the 

start. Mr. DuVal’s patent had already survived one 

ex parte reexamination Thryv instigated. The patent had 

been the subject of long and repeated litigation in federal 

courts. The agency had no business opening yet another 

new inquiry into this very old patent. 

But Thryv had one maneuver left. It sought review in 

this Court, insisting that Article III courts lack authority 

even to say what the law demands. According to Thryv, a 

different provision, §314(d), renders the agency’s interpretations and applications of §315(b) immune from judicial review. So the Board can err; it can even act in defiance of 

plain congressional limits on its authority. But, in Thryv’s 

view, a court can do nothing about it. Enforcement of 

§315(b)’s time bar falls only to the very Patent Office officials whose authority it seeks to restrain. Inventors like 

Mr. DuVal just have to hope that the bureaucracy revoking

their property rights will take the extra trouble of doing so 

in accordance with law. 
 

6 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

That’s the strange place we now find ourselves. Thryv

managed to persuade the Court to grant its petition for 

certiorari to consider its extraordinary argument. And 

today the Court vindicates its last and most remarkable 

maneuver. 

II 

A 

How could §314(d) insulate from judicial review the 

agency’s—admittedly mistaken—interpretation of an entirely different provision, §315(b)? The answer is that it 

doesn’t. 

To see why, look no further than §314(d). The statute 

tells us that “[t]he determination by the Director whether

to institute an inter partes review under this section shall 

be final and nonappealable.” So the only thing §314(d) insulates from judicial review is “[t]he determination” made 

“by the Director” “under this section”—that is, a determination discussed within §314. Nothing in the statute insulates agency interpretations of other provisions outside 

§314, including those involving §315(b). 

This arrangement makes sense. Given that §314(d)

speaks of “[t]he” determination by the Director “under this

section,” it comes as no surprise that the section mentions

just one such “determination.” It is found in §314(a), where

the Director “determines” whether the parties’ initial pleadings suggest “a reasonable likelihood” the petitioner will 

prevail in defeating at least some aspect of the challenged 

patent. And it is easy to see why Congress might make a 

preliminary merits assessment like that exempt from further view: If the Director institutes a meritless petition, the 

Board can summarily affirm the patent’s validity. See 

§318(a); 37 CFR §§42.71–42.73. In any event, the Board is

obligated to render a final—and judicially reviewable—decision within a year. 35 U. S. C. §§141(c), 316(a)(11), 
Cite as: 590 U. S. ____ (2020) 7 

GORSUCH, J., dissenting 

318(a), 319. So judicial review of the Director’s initial appraisal of the merits isn’t really eliminated as much as it is 

channeled toward the Board’s final decision on those merits. That process finds a ready analogue elsewhere in our 

law. Much as here, an indicted criminal defendant unhappy with a grand jury’s finding of probable cause isn’t 

permitted to challenge that preliminary assessment, but 

may instead move the court for acquittal after the government has presented all its evidence. See Costello v. United 

States, 350 U. S. 359, 363 (1956); Fed. Rule Crim. Proc. 

29(a).

Matters outside §314 are different. Take the provision

before us, §315(b). It promises that an inter partes review

“may not be instituted” more than a year after the initiation

of litigation. This stands as an affirmative limit on the 

agency’s authority. Much like a statute of limitations, this 

provision supplies an argument a party can continue to 

press throughout the life of the administrative proceeding

and on appeal. Nothing in §315(b) speaks of a “determination by the Director,” let alone suggests that the

agency’s initial ruling on a petition’s timeliness is “final and 

nonappealable.” 

To pretend otherwise would invite a linguistic nonsense. 

We would have to read §314’s language speaking of “[t]he”

“determination” “under this section” to include not one determination but two—and to include not only the determination actually made under “this section” but also a second 

assessment made about the effect of an entirely different

section. 

To pretend otherwise would invite a practical nonsense

as well. Because the Director’s initial “reasonable likelihood” determination under §314(a) relates to the merits, it 

will be effectively reviewed both by the Board and courts as

the case progresses. But when does the Director’s application of §315(b)’s time bar get another look? Under Thryv’s

interpretation, a provision that reads like an affirmative 
 

 

8 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

limit on the agency’s authority reduces to a mere suggestion. No matter how wrong or even purposefully evasive, 

the Director’s assessment of a petition’s timeliness is always immune from review. And even that’s not the end of 

it. In other cases, the Board has claimed it has the right to 

review these initial timeliness decisions, and Thryv seems 

content with those rulings. See, e.g., Medtronic, Inc. v. Robert Bosch Healthcare Systems, Inc., 839 F. 3d 1382 (CA Fed. 

2016). So it turns out the company doesn’t really want to 

make an initial administrative timeliness decisions final; it 

just wants to make them unreviewable in court, defying

once more §314’s plain language and any rational explanation, except maybe as an expedient to win the day’s case. 

B 

Confronting so many problems in the statute’s text,

Thryv seeks a way around them by offering a competing account of the law’s operation. While §314 empowers the Director to make an institution decision, Thryv asserts that

various provisions scattered throughout the chapter—such 

as §§314(a), 315(a)(1), and 315(b)—help guide the decision.

And on Thryv’s interpretation, all questions related to the 

Director’s institution decision should be insulated from review, no matter where those rules are found. What about 

the fact §314 speaks of insulating only “[t]he” “determination” “under this section”? Thryv says this language serves 

merely to indicate which institution authority is unreviewable—namely, the Director’s authority to institute an inter

partes proceeding pursuant to §314, rather than pursuant 

to some other provision.

This interpretation, however, makes a nullity of the very 

language it purports to explain. Section 314 is the only section that authorizes the Director to institute inter partes 

review, making it pointless for Congress to tell us that we’re

talking about the Director’s §314 inter partes review insti-
 

Cite as: 590 U. S. ____ (2020) 9 

GORSUCH, J., dissenting 

tution authority as opposed to some other inter partes review institution authority. In fact, you can strike “under 

this section” from §314(d) and Thryv’s interpretation remains unchanged. That’s a pretty good clue something has 

gone wrong.

Faced with this problem of surplusage, Thryv alludes to 

the possibility that Congress included redundant language 

to be “double sure.” But double sure of what? Thryv does

not identify any confusion that the phrase “under this section” might help avoid. Given the lack of any other provision, anywhere in the U. S. Code, authorizing anyone to institute inter partes review, even the most obtuse reader

would never have any use for the clarification supposedly 

provided by “under this section” on Thryv’s account. 

Maybe so, Thryv replies, but we shouldn’t worry about 

the surplusage here because the AIA contains surplusage

elsewhere. The other putative examples of surplusage

Thryv identifies, however, have no bearing on the provision 

now before us. And even a passing glance reveals no surplusage in them either. Consider §315(c). It says that “the

Director, in his or her discretion, may join as a party to that

inter partes review any person who properly files a petition 

under section 311 that the Director, after receiving a preliminary response under section 313 . . . , determines warrants the institution of an inter partes review under section 

314.” (Emphasis added.) Thryv argues that all these crossreferences are unnecessary. But look closely: Each of 

§315(c)’s cross-references does important work to establish 

the rules for joinder. Strike the first and the requirements

of a joinder petition become undefined. Strike the second 

and it’s a mystery what kind of response the patent owner 

is entitled to file. Strike the third and the Director’s determination whether to grant joinder becomes standardless.

All of this language has a point to it—just as “under this

section” does under a faithful interpretation of §314(d).

That leaves Thryv only one more tenuous textual lifeline 
 

10 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

left to toss. If Congress had wanted to insulate from review 

only “[t]he” “determination” that a petition has a “reasonable likelihood” of success, the company suggests, Congress 

could have spoken of insulating “the determination under

subsection (a)” rather than “the determination under this 

section.” And Thryv reminds us that Congress used that 

latter formulation in nearby and predecessor statutes. See, 

e.g., §303(c) (“[a] determination by the Director pursuant to

subsection (a) of this section . . . will be final and nonappealable”); §312(c) (2006 ed.; repealed 2011) (“[a] determination

by the Director under subsection (a) shall be final and 

non-appealable”).

But so what? One could replace the phrase “my next-door

neighbor to the west” with “my neighbor at 123 Main 

Street” (assuming that is her address) and the meaning

would be the same. Likewise, it hardly matters whether 

Congress spoke of the “determination” “under this section” 

or “under subsection (a).” Either way, our attention is directed within, not beyond, §314. And what’s Thryv’s alternative? It would have us read language speaking of the Director’s determination “under this section” to encompass

any decision related to the initiation of inter partes review 

found anywhere in the AIA—an entire chapter of the U. S. 

Code. That’s sort of like reading “my next-door neighbor to

the west” to include “anyone in town.” Nor do things get

better for Thryv with a careful assessment of nearby and

predecessor statutes. They reveal that Congress knew exactly how to give broader directions like the one Thryv imagines when it wished to do so. See, e.g., §314(b) (directing

our attention to the Director’s decision whether to institute 

inter partes review “under this chapter” rather than “under 

this section”).

Without any plausible textual or contextual hook for its 

position, Thryv finishes by advancing a parade of policy 

horribles. It notes that the AIA imposes lots of other constraints on inter partes review besides the §315(b) timing

GORSUCH, J., dissenting 

provision now before us. For example, the law bars petitioners who have filed declaratory judgment actions from 

challenging the same patent in inter partes review proceedings, §315(a)(1), and it estops petitioners from seeking other 

forms of review once an inter partes proceeding finishes, 

§315(e). If courts are going to review the agency’s application of §315(b), Thryv wonders, are they going to have to 

review the agency’s application of these other provisions 

too? 

But we could just as easily march this parade in the opposite direction. Even assuming (without deciding) that

Thryv is right and the reviewability of all these provisions 

stands or falls together, that seems at least as good an argument for as against judicial review. If so much more is 

at stake, if many more kinds of agency errors could be insulated from correction, isn’t that a greater reason to pay assiduous attention to the statute’s terms? Surely, Thryv’s 

professed concern for judicial economy supplies no license

to ignore our duty to decide the cases properly put to us in

accord with the statute’s terms. 

III 

This last point leads to another reason why we should reject Thryv’s reading of the statute. Even if the company 

could muster some doubt about the reach of §314(d), it

wouldn’t be enough to overcome the “well-settled presumption favoring interpretations of statutes that allow judicial

review of administrative action.” McNary v. Haitian Refugee Center, Inc., 498 U. S. 479, 496 (1991). As this Court 

has long explained, “we will . . . find an intent to preclude 

such review only if presented with clear and convincing evidence.” Reno v. Catholic Social Services, Inc., 509 U. S. 43, 

64 (1993) (internal quotation marks omitted).

The presumption of judicial review is deeply rooted in our 

history and separation of powers. To guard against arbitrary government, our founders knew, elections are not 
 

12 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

enough: “An elective despotism was not the government we

fought for.” The Federalist No. 48, p. 311 (C. Rossiter ed. 

1961) (emphasis deleted). In a government “founded on free 

principles,” no one person, group, or branch may hold all

the keys of power over a private person’s liberty or property. 

Ibid. Instead, power must be set against power, “divided 

and balanced among several bodies . . . checked and restrained by the others.” Ibid. As Chief Justice Marshall 

put it: “It would excite some surprise if, in a government of

laws and of principle . . . a department whose appropriate

duty it is to decide questions of right, not only between individuals, but between the government and individuals,” a

statute might leave that individual “with no remedy, no appeal to the laws of his country, if he should believe the claim 

to be unjust.” United States v. Nourse, 9 Pet. 8, 28–29 

(1835).

It should come as an equal surprise to think Congress

might have imposed an express limit on an executive bureaucracy’s authority to decide the rights of individuals,

and then entrusted that agency with the sole power to enforce the limits of its own authority. Yet on Thryv’s account, 

§315(b)’s command that “inter partes review may not be instituted” would be left entrusted to the good faith of the very

executive officials it is meant to constrain. (Emphasis 

added.) We do not normally rush to a conclusion that Congress has issued such “‘blank checks drawn to the credit of 

some administrative officer.’” Bowen v. Michigan Academy 

of Family Physicians, 476 U. S. 667, 671 (1986) (quoting 

S. Rep. No. 752, 79th Cong., 1st Sess., 26 (1945)).

That usually may be the case, Thryv counters, but this

statute’s unusually modest purpose makes it plausible to

think Congress meant to shield its application from judicial 

review. After all, the company submits, §315(b) is not really 

a firm limit on the agency’s authority, only a claim processing rule. For proof, the company reminds us that 
Cite as: 590 U. S. ____ (2020) 13 

GORSUCH, J., dissenting 

§315(b) bars challengers who have already spent a year litigating in court from petitioning the agency, but leaves

open the possibility that the agency might still institute inter partes review if a different, eligible petitioner happens

to come along. And this theoretical possibility, Thryv tells 

us, suggests that the agency was meant to be allowed to act 

as it wants. 

But Thryv’s reply here is like saying Article III’s “case or 

controversy” requirement isn’t really a limit on the power 

of federal courts, because it’s always possible that some litigant with a live dispute will come forward and require the 

court to settle a particular legal question. The implacable 

fact is that nothing in the AIA gives the Director or the 

Board freewheeling authority to conduct inter partes review. The statute demands the participation of a real party 

in interest, a petitioner who is not barred by prior litigation 

and who is willing to face estoppel should he lose. §§311(a), 

315. And if, as seems likely in our case and many others, 

no one is willing and able to meet those conditions, the law 

does not permit inter partes review. So rather than a claim 

processing rule, §315 is both a constraint on the agency’s

power and a valuable guarantee that a patent owner must 

battle the same foe only once. 

Realizing that its textual arguments are too strained to

demonstrate clearly and convincingly that Congress meant 

to displace judicial review, Thryv asks us to draw “inferences” from the AIA “as a whole.” Brief for Petitioner 16 

(internal quotation marks omitted). In particular, the company tells us that Congress’s “overriding purpose” in creating inter partes review was to “weed out poor quality patents,” and that judicial enforcement of §315(b) would slow 

this progress. Id., at 24 (quotation altered). But to support

its thematic account of the law’s goals, Thryv rests on one 

thin reed after another—a House Report here, a floor statement there, and a few quotations from Cuozzo Speed Technologies, LLC v. Lee, 579 U. S. ___ (2016), that summarize 
 

14 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

these same sources. All the rest is generously filled in by

the company’s own account about how inter partes review 

ought to work. 

That’s far from enough. The historic presumption of judicial review has never before folded before a couple stray 

pieces of legislative history and naked policy appeals. Besides, Thryv’s submissions cannot withstand the mildest inspection even on their own terms. No one doubts that Congress authorized inter partes review to encourage further 

scrutiny of already issued patents. But lost in Thryv’s telling about the purposes of the AIA is plenty of evidence that 

Congress also included provisions to preserve the value of 

patents and protect the rights of patent owners. For example, Congress sharply limited the legal grounds that might 

be pursued in inter partes review, §311(b); afforded patent 

owners an opportunity to respond to petitions prior to institution, §313; and, most relevant today, protected patent 

owners from the need to fight a two-front war before both 

the Board and federal district court, §315. Legislating involves compromise and it would be naive to think that, as

the price for their zealous new procedures for canceling patents, those who proposed the AIA didn’t have to accept 

some protections like these for patent holders. Yet, Thryv

glides past all these provisions without comment. Worse, 

taking the company’s argument to its logical conclusion

could render these protections into “‘merely advisory’” features of the law. Bowen, 476 U. S., at 671. If adopted,

Thryv’s vision of an administrative regime singularly focused on the efficient canceling of patents could become 

self-fulfilling.

A case decided just weeks ago supplies a telling point of 

comparison. In Guerrero-Lasprilla v. Barr, 589 U. S. ___ 

(2020), Congress sought to expedite the removal of aliens

convicted of certain aggravated felonies by foreclosing judicial review of their cases unless they raised “questions of

law.” See 8 U. S. C. §§1252(a)(2)(C), (D). But the statute 
 

Cite as: 590 U. S. ____ (2020) 15 

GORSUCH, J., dissenting 

there was ambiguous about mixed questions of law and fact: 

Were these (reviewable) questions of law, or (unreviewable) 

determinations of fact? Because the statute could be interpreted either way, this Court held, the presumption of reviewability preserved the aliens’ ability to argue mixed 

questions on appeal. Today, the textual arguments for

shielding the agency’s decision from review are even 

weaker, and the same presumption that preserved judicial

review for felons seeking discretionary relief from removal 

should do no less work for patent holders seeking to defend

their inventions. 

IV 

Even if the statute’s plain language and the presumption 

in favor of review dictate a ruling against it, Thryv finishes 

by suggesting we must ignore all that and rule for it anyway 

because precedent commands it. Maybe our precedent is

wrong, the company says, but it binds us all the same.

In particular, Thryv points us to Cuozzo. There, the 

Court suggested that §314(d) could preclude review in 

cases: (1) where a litigant challenges the Director’s reasonable likelihood of success determination under §314(a), or 

(2) where a litigant “grounds its claim in a statute closely 

related to that decision to institute inter partes review.”

579 U. S., at ___ (slip op., at 12). That first path is faithful

to the plain language of §314(d). The second appears nowhere in the statute but is, instead, a product of the judicial 

imagination. Still, Thryv says, we must follow that path 

wherever it leads and, because §315(b) decisions are 

“closely related” to §314(a) decisions, we shouldn’t review 

them. 

But Cuozzo hardly held so much. In fact, Cuozzo had no 

need to explore the second path it imagined, for it quickly 

concluded that the argument before it was “little more than 

a challenge to the Patent Office’s conclusion under §314(a),” 
 

 

 

16 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

a decision shielded from judicial review under any interpretation of §314(d). Id., at ___ (slip op., at 12). So all the discussion about the reviewability of decisions outside §314(a)

turned out to be nothing more than dicta entirely unnecessary to the decision. Nor did anything in Cuozzo directly

address §315(b) decisions, let alone declare them to 

be “close enough” to §314(a) decisions to preclude judicial

review. 

That’s just the beginning of Thryv’s precedent problems, 

too. In SAS Institute Inc. v. Iancu, 584 U. S. ___ (2018), an 

inter partes review petitioner challenged the Director’s

practice of instituting review of some, but not all, of the 

claims challenged in a single petition. The government argued there—much as Thryv argues today—that §314(d) 

shielded this unlawful practice from judicial review. In advancing this argument, the government seized on the same

language in Cuozzo that Thryv now embraces, claiming 

that its opponent’s “grounds for attacking the decision . . . 

are closely tied” to the §314(a) institution decision. Brief 

for Federal Respondent in SAS Institute Inc. v. Iancu, O. T. 

2017, No. 16–969, p. 13. Because no one could say that the 

petitioner’s argument in SAS Institute was “little more than 

a challenge to the Patent Office’s conclusion under §314(a),” 

584 U. S., at ___ (slip op., at 13), we were forced to confront

whether Cuozzo and the relevant statutes actually barred

not just institution decisions under §314(a) but things 

“closely related” to them.

We held they did not. We began, as we did in Cuozzo, by

noting the “strong presumption in favor of judicial review.” 

SAS Institute, 584 U. S., at ___ (slip op., at 13) (internal 

quotation marks omitted). We then put an end to any doubt

about what the dicta in that case might mean: “Given the 

strength of this presumption and the statute’s text, Cuozzo 

concluded that §314(d) precludes judicial review only of the 

Director’s ‘initial determination’ under §314(a).” Ibid. 

(quoting Cuozzo, 579 U. S., at ___ (slip op., at 9); emphasis 
 

Cite as: 590 U. S. ____ (2020) 17 

GORSUCH, J., dissenting 

added). We did not need to overrule Cuozzo, because the 

language the government seized upon from that opinion

was dicta from the start. Still, we made it clear that dicta’s 

day had come: To read Cuozzo as “foreclosing judicial review of any legal question bearing on the institution decision,” we explained, would “overrea[d] both the statute and 

our precedent.” SAS Institute, 584 U. S., at ___–___ (slip 

op., at 12–13). The petitioner’s challenge to the Director’s

partial institution practice could go forward exactly because

it was something other than a disagreement about the Director’s initial determination under §314(a). Id., at ___–___ 

(slip op., at 13–14). 

It’s not surprising that litigants would invite us to 

overread dicta or overlook an unfavorable precedent. What 

is surprising is that the Court would accept the invitation.

In ‘‘cases involving property,” after all, “considerations favoring stare decisis are at their acme.” Kimble v. Marvel 

Entertainment, LLC, 576 U. S. 446, 457 (2015) (internal 

quotation marks omitted). And we are often reminded that 

“stare decisis carries enhanced force when a decision . . . interprets a statute.” Id., at 456. But rather than searching 

for the kind of “superspecial justification,” id., at 458, this 

Court supposedly requires to overrule a precedent like SAS 

Institute, today’s majority quibbles with a few sentences

and quietly walks away. If, as some have worried, “[e]ach

time the Court overrules a case, the Court . . . cause[s] the

public to become increasingly uncertain about which cases

the Court will overrule,” Franchise Tax Bd. of Cal. v. Hyatt, 

587 U. S. ___, ___ (2019) (slip op., at 13), (BREYER, J., dissenting), one can only imagine what a judicial shrug of the 

shoulders like this might yield. 

Litigants and lower courts will also have to be forgiven 

for the confusion to come about the meaning of §314(d)’s review bar. Whether it is limited to the §314(a) determination (as SAS Institute held and parts of Cuozzo suggested)

or also reaches to challenges grounded in “closely related” 
 

18 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

statutes (as other parts of Cuozzo suggested and the Court

insists today)—who can say? And even supposing that 

“closely related to institution” really is the test we’ll apply 

next time, does anyone know what this judicially concocted

formulation even means? Despite three opinions interpreting the same provision in under five years, only one thing 

is clear: Neither the statute nor our precedent can be

counted upon to give the answer. Litigants and lower

courts alike will just have to wait and see. 

V 

It’s a rough day when a decision manages to defy the

plain language of a statute, our interpretative presumptions, and our precedent. But today that’s not the worst of 

it. The Court’s expansive reading of §314(d) takes us further down the road of handing over judicial powers involving the disposition of individual rights to executive agency 

officials. 

We started the wrong turn in Oil States Energy Services, 

LLC v. Greene’s Energy Group, LLC, 584 U. S. ___ (2018). 

There, a majority of this Court acquiesced to the AIA’s provisions allowing agency officials to withdraw already-issued 

patents subject to very limited judicial review. As the majority saw it, patents are merely another public franchise 

that can be withdrawn more or less by executive grace. So 

what if patents were, for centuries, regarded as a form of 

personal property that, like any other, could be taken only

by a judgment of a court of law. So what if our separation

of powers and history frown on unfettered executive power 

over individuals, their liberty, and their property. What the 

government gives, the government may take away—with or

without the involvement of the independent Judiciary. Today, a majority compounds that error by abandoning a good 

part of what little judicial review even the AIA left behind.

Just try to imagine this Court treating other individual

GORSUCH, J., dissenting 

liberties or forms of private property this way. Major portions of this country were settled by homesteaders who

moved west on the promise of land patents from the federal 

government. Much like an inventor seeking a patent for his 

invention, settlers seeking these governmental grants had 

to satisfy a number of conditions. But once a patent issued, 

the granted lands became the recipient’s private property, 

a vested right that could be withdrawn only in a court of 

law. No one thinks we would allow a bureaucracy in Washington to “cancel” a citizen’s right to his farm, and do so despite the government’s admission that it acted in violation

of the very statute that gave it this supposed authority. For 

most of this Nation’s history it was thought an invention 

patent holder “holds a property in his invention by as good 

a title as the farmer holds his farm and flock.” Hovey v. 

Henry, 12 F. Cas. 603, 604 (No. 6,742) (CC Mass. 1846) 

(Woodbury, J., for the court). Yet now inventors hold nothing for long without executive grace. An issued patent becomes nothing more than a transfer slip from one agency 

window to another. 

Some seek to dismiss this concern by noting that the bureaucracy the AIA empowers to revoke patents is the same 

one that grants them. But what comfort is that when the 

Constitution promises an independent judge in any case involving the deprivation of life, liberty, or property? Would 

it make things any better if we assigned the Department of

the Interior the task of canceling land patents because that

agency initially allocated many of them? The relevant constitutional fact is not which agency granted a property

right, but that a property right was granted.

The abdication of our judicial duty comes with a price.

The Director of the Patent and Trademark Office is a political appointee. The AIA vests him with unreviewable authority to institute (or not) inter partes review. Nothing

would prevent him, it seems, from insulating his favorite

firms and industries from this process entirely. Those who 
 

 

20 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

are not so fortunate proceed to an administrative “trial” before a panel of agency employees that the Director also has 

the means to control. The AIA gives the Director the power

to select which employees, and how many of them, will hear 

any particular inter partes challenge. It also gives him the

power to decide how much they are paid. And if a panel 

reaches a result he doesn’t like, the Director claims he may

order rehearing before a new panel, of any size, and including even himself.

No one can doubt that this regime favors those with political clout, the powerful and the popular. But what about 

those who lack the resources or means to influence and 

maybe even capture a politically guided agency? Consider 

Mr. DuVal, who 25 years ago, came up with something the 

Patent Office agreed was novel and useful. His patent survived not only that initial review but a subsequent administrative ex parte review, a lawsuit, and the initiation of another. Yet, now, after the patent has expired, it is

challenged in still another administrative proceeding and

retroactively expunged by an agency that has, by its own 

admission, acted unlawfully. That is what happens when

power is not balanced against power and executive action

goes unchecked by judicial review. Rather than securing

incentives to invent, the regime creates incentives to curry

favor with officials in Washington. 

Nor is it hard to imagine what might lie around the corner. Despite repeated lawsuits, no court ever ruled definitively on Mr. DuVal’s patents. But suppose one had—and

suppose he had prevailed. According to the agency, even

that judgment might not matter much. In other cases, the 

Board has claimed the power through inter partes review 

to overrule final judicial judgments affirming patent rights.

In the Director’s estimation, it appears, even this Court’s 

decisions must bow to the Board’s will. See XY, LLC v. 

Trans Ova Genetics, L. C., 890 F. 3d 1282, 1285–1286, 

1294–1295 (CA Fed. 2018); Fresenius USA, Inc. v. Baxter 
Cite as: 590 U. S. ____ (2020) 21 

GORSUCH, J., dissenting 

Int’l, Inc., 721 F. 3d 1330, 1340–1344 (CA Fed. 2013). It’s 

no wonder, then, that district courts sometimes throw up 

their hands and let the Board take over whenever inter 

partes review and patent litigation begin to overlap. Why

bother with a trial if “the finality of any judgment rendered 

by [a] Court will be dubious”? Order Granting Stay in 

Click-to-call Technologies LP v. Ingenio, Inc., No. 12–cv– 

00465 (WD Tex.), Doc. No. 147, p. 4. 

It’s understandable, too, why the agency might think so 

much is up for grabs. Not only did this Court give away

much of its Article III authority in Oil States on a mistaken 

assessment that patents were historically treated as public

franchises rather than private rights. Some would have 

had the Court go even further. Rather than looking to history to determine how patents were treated, as both the majority and dissent sought to do, these Members of the Court 

suggested that agencies should be allowed to withdraw 

even private rights if “a number of factors”—taken together, of course—suggest it’s a good idea. Commodity Futures Trading Comm’n v. Schor, 478 U. S. 833, 851 (1986); 

see also Oil States, 584 U. S., at ___ (BREYER, J., concurring) (slip op., at 1). These “factors” turn out to include such 

definitive and easily balanced considerations as the “nature

of the claim,” the “nature of the non-Article III tribunal,” 

and the “nature and importance of the legislative purpose

served by the grant of adjudicatory authority to a tribunal 

with judges who lack Article III’s tenure and compensation

protections.” Stern v. Marshall, 564 U. S. 462, 513 (2011) 

(BREYER, J., dissenting). In other words, Article III promises that a person’s private rights may be taken only in proceedings before an independent judge, unless the government’s goals would be better served by a judge who isn’t so 

independent.

Thryv seeks to assure us that affected parties can still file

writs of mandamus in courts if the Patent Office gets really 
 

22 THRYV, INC. v. CLICK-TO-CALL TECHNOLOGIES, LP 

GORSUCH, J., dissenting 

out of hand. But the Court today will not say whether mandamus is available where the §314(d) bar applies, and the 

Federal Circuit has cast doubt on that possibility. In re 

Power Integrations, Inc., 899 F. 3d 1316, 1319 (2018) (“We 

have held that the statutory prohibition on appeals from 

decisions not to institute inter partes review cannot be sidestepped simply by styling the request for review as a petition for mandamus”); In re Procter & Gamble Co., 749 F. 3d 

1376 (2014); In re Dominion Dealer Solutions, LLC., 749 

F. 3d 1379 (2014). Even assuming mandamus is available, 

it is a “drastic [remedy], to be invoked only in extraordinary

situations.” Kerr v. United States Dist. Court for Northern 

Dist. of Cal., 426 U. S. 394, 402 (1976). To be eligible for 

this discretionary relief, a petitioner must first show a 

“clear and indisputable” right. Id., at 403 (internal quotation marks omitted). But how often could a litigant show 

such a “clear and indisputable” right in an area where

courts shirk their duty to say what the law is in the first

place? And how would a court find the will to call a situation “extraordinary” once the agency has been free for so

long to ignore the limits on its power? If the case before us 

doesn’t qualify as “extraordinary,” and if the Board’s admitted flouting of §315(b) isn’t “clear and indisputable,” then 

what extralegal act wouldn’t be just another day at the 

office? 

* 

Two years ago, this Court sanctioned a departure from

the constitutional plan, one in which the Executive Branch

assumed responsibilities long reserved to the Judiciary. In 

so doing, we denied inventors the right to have their claims

tried before independent judges and juries. Today we compound that error, not only requiring patent owners to try 

their disputes before employees of a political branch, but 

limiting their ability to obtain judicial review when those

same employees fail or refuse to comply with the law. Nothing in the statute commands this result, and nothing in the 

Constitution permits it. Respectfully, I dissent.
