Before PROST, TARANTO, and CHEN, Circuit Judges.
PROST, Circuit Judge.
CyWee Group Ltd. (“CyWee”) requested that the Direc-
tor of the U.S. Patent and Trademark Office (“PTO”) rehear
two inter partes review (“IPR”) proceedings, each of which
Case: 20-1565 Document: 153 Page: 3 Filed: 02/08/2023
CYWEE GROUP LTD. v. GOOGLE LLC 3
had resulted in a final written decision of the Patent Trial
and Appeal Board (“Board”) determining all challenged
claims unpatentable. CyWee’s request was denied as to
each IPR. CyWee appeals those denials. We affirm.
BACKGROUND
In June 2018, Google LLC (“Google”) filed two petitions
for IPR challenging certain claims of CyWee’s patents. Cy-
Wee filed a preliminary response to each petition on Sep-
tember 14, 2018. On December 11, 2018—within three
months of CyWee’s preliminary responses—the Board in-
stituted (for each petition) IPR on all challenged claims.
After institution, each IPR was joined by other parties. Be-
cause of those joinders, on December 4, 2019, the Board ex-
tended its deadline for the final written decisions—a
deadline that’s typically one year from institution—by one
month, making the new deadline January 10, 2020. E.g.,
J.A. 7869–73. On January 9, 2020, the Board issued its
final written decision in each IPR, determining all respec-
tive challenged claims unpatentable for obviousness.
CyWee appealed both Board decisions to this court in
March 2020, and we consolidated the appeals. In addition
to challenging the merits of the Board’s unpatentability de-
terminations, CyWee challenged the appointment of Board
administrative patent judges (“APJs”) as unconstitutional
in view of the Appointments Clause, U.S. CONST. art. II,
§ 2, cl. 2. In a March 2021 decision, we affirmed. We re-
jected CyWee’s Appointment Clause challenge as fore-
closed by our then-governing precedent, including Arthrex,
Inc. v. Smith & Nephew, Inc., 941 F.3d 1320 (Fed. Cir.
2019). See CyWee Grp. Ltd. v. Google LLC, 847 F. App’x
910, 913 (Fed. Cir. 2021). We also rejected or otherwise
disposed of CyWee’s other challenges. Id. at 912–14. Cy-
Wee petitioned for panel and en banc rehearing. After
denying both, this court issued its mandate on June 10,
2021.
Case: 20-1565 Document: 153 Page: 4 Filed: 02/08/2023
4 CYWEE GROUP LTD. v. GOOGLE LLC
Eleven days after the mandate, the Supreme Court is-
sued its decision in United States v. Arthrex, Inc., 141 S. Ct.
1970 (2021) (“Arthrex”). The Court held in Arthrex that
APJs’ power to render final patentability decisions unre-
viewable by an accountable principal officer gave rise to an
Appointments Clause violation. Id. at 1980–82, 1985. The
Court remedied the violation by (1) vitiating anything in
35 U.S.C. § 6(c) that prevented the Director from reviewing
final Board decisions in the IPR context and (2) “re-
mand[ing] to the Acting Director for him to decide whether
to rehear” the case. Id. at 1987.
After Arthrex issued, CyWee moved this court to recall
its mandate and remand to the PTO for proceedings con-
sistent with Arthrex. We recalled the mandate, remanded
“for the limited purpose of allowing CyWee the opportunity
to request Director rehearing of the final written deci-
sions,” and required CyWee to inform this court within
14 days of any decision denying rehearing. Order at 3
(Sept. 23, 2021), ECF No. 109. On remand, CyWee’s re-
quests for Director rehearing were referred to the Commis-
sioner for Patents, who at the time was performing the non-
exclusive functions of the Director and Deputy Director
(those two offices were vacant at the time). The Commis-
sioner denied rehearing and ordered that the Board’s final
written decisions were “the final decision[s] of the agency.”
J.A. 41578. CyWee thereafter filed, in accordance with an
order of this court, amended notices of appeal challenging
the rehearing denials.
CyWee’s opening brief challenged, among other things,
the Commissioner’s authority to perform the review Ar-
threx contemplates. Before any response brief was filed,
Google moved to stay the appeal, citing the relatively ad-
vanced state of this court’s consideration of the same issues
in Arthrex, Inc. v. Smith & Nephew, Inc., No. 18-2140, as
argued and submitted to a panel of this court on March 30,
2022. We stayed the instant case pending this court’s man-
date in that case.
Case: 20-1565 Document: 153 Page: 5 Filed: 02/08/2023
CYWEE GROUP LTD. v. GOOGLE LLC 5
Less than three weeks after we stayed the instant case,
the referenced panel issued its decision, rejecting chal-
lenges concerning the Commissioner’s authority to perform
the review Arthrex contemplates. Arthrex, Inc. v. Smith &
Nephew, Inc., 35 F.4th 1328 (Fed. Cir. 2022) (“Arthrex II”).
After this court’s mandate in Arthrex II, we lifted the stay
in the instant case and directed CyWee to file a supple-
mental brief identifying the arguments from its opening
brief that it believed were not foreclosed or otherwise re-
solved by Arthrex II. Order (Sept. 7, 2022), ECF No. 135.
We have jurisdiction under 28 U.S.C. § 1295(a)(4)(A).
DISCUSSION
CyWee seems to acknowledge that Arthrex II compels
rejecting its challenges to the Commissioner’s authority to
perform the review Arthrex contemplates, including Cy-
Wee’s challenges under the Appointments Clause, the Fed-
eral Vacancies Reform Act, and the Constitution’s
separation of powers. See Appellant’s Supp. Br. 2–3. 1 Cy-
Wee also seems to acknowledge that our decision in In re
Palo Alto Networks, Inc., 44 F.4th 1369 (Fed. Cir. 2022),
compels rejecting its Appointments Clause challenge re-
garding the institution decisions. See Appellant’s Supp.
Br. 3–4. And regardless of CyWee’s willingness to concede
the points, we conclude that Arthrex II and In re Palo Alto
Networks compel rejecting those challenges. See Arthrex
II, 35 F.4th at 1333–40; In re Palo Alto Networks, 44 F.4th
at 1375 (“[T]he statutory and regulatory provisions con-
cerning institution do not violate the Appointments
Clause.”).
CyWee also argues that the Board’s institution deci-
sions and final written decisions were untimely. Appel-
lant’s Br. 19–21; 2 see id. at 39–40 (styling the untimeliness

arguments as implicating “due process”); Reply Br. 2–5. 3
According to CyWee, it was not enough that the Board in-
stituted the IPRs within the statutorily required three
months of receiving CyWee’s preliminary responses. See
35 U.S.C. § 314(b). Nor was it enough that the Board is-
sued its final written decisions within the time the statute
contemplates (i.e., one year from institution, plus in this
case an additional one month due to joinder). See 35 U.S.C.
§ 316(a)(11). Rather, CyWee insists, not only must the Di-
rector be able to review institution decisions and final writ-
ten decisions, she also must perform (or have the
opportunity to perform) such a review within the statutory
deadlines applicable to those decisions. See, e.g., Reply
Br. 4 (“The [PTO] argues that the three-month deadline in
§ 314(b) (for institution) and the one-year deadline in
§ 316(a)(11) (for the final written decision) do not apply to
any Director review decisions. This is incorrect.” (cleaned
up)).
CyWee’s untimeliness arguments are meritless. The
statutory provisions setting specific deadlines for institu-
tion decisions and final written decisions say nothing of
deadlines for any further Director review of those deci-
sions. For an institution decision, § 314(b) provides that,
as relevant here, “[t]he Director shall determine whether
to institute an [IPR] . . . within 3 months after . . . receiving
a preliminary response to the petition.” The Director has
permissibly delegated to the Board the determination of
whether to institute an IPR. Ethicon Endo-Surgery, Inc. v.
Covidien LP, 812 F.3d 1023, 1031–33 (Fed. Cir. 2016) (cit-
ing, among other things, 37 C.F.R. § 42.4(a)); In re Palo
Alto Networks, 44 F.4th at 1373, 1375–77. If the Board
makes that determination within the § 314(b) deadline—
and here, it did—the institution decision is timely, notwith-
standing the possibility that the Director may later revisit
3 “Reply Br.” refers to ECF No. 145.
Case: 20-1565 Document: 153 Page: 7 Filed: 02/08/2023
CYWEE GROUP LTD. v. GOOGLE LLC 7
that decision. For a final written decision, § 316(a)(11) re-
quires the Director to prescribe regulations “requiring that
the final determination in an [IPR] be issued not later than
1 year after” an institution decision is noticed, except that
the Director may adjust that one-year deadline under cer-
tain circumstances. The Director has prescribed such a
regulation. See 37 C.F.R. § 42.100(c) (“An [IPR] proceeding
shall be administered such that pendency before the Board
after institution is normally no more than one year.”).
Here, due to joinder, the Board extended the one-year
deadline by one month and issued its final written deci-
sions within that extended deadline. So, unless CyWee can
show that this extension was improper (and as discussed
below, it hasn’t), the Board’s final written decisions were
timely—again, notwithstanding the possibility that the Di-
rector could have later reviewed those decisions. 4
Likewise meritless is CyWee’s argument that the
Board lacked authority to extend the one-year deadline for
final written decisions in the case of joinder. The relevant
statutory provision, § 316(a)(11), states that the Director
4 CyWee’s reply brief might be read to argue that Di-
rector review of institution decisions and final written de-
cisions (or the opportunity for such review) need not comply
with the specific deadlines contemplated by §§ 314(b) and
316(a)(11) but instead with more general notions of timeli-
ness. See Reply Br. 5 (citing 35 U.S.C. § 316(b), which re-
quires the Director to consider the effect of certain
regulations on the PTO’s ability to “timely complete pro-
ceedings instituted under this chapter”); see also id. at 4
(arguing that Director review of a final written decision
must occur “in a reasonable time”). But even assuming (for
argument’s sake) that such a general timeliness require-
ment exists, and that we could review compliance with it,
we see nothing suggesting that the PTO proceedings here
would have violated such a requirement.

“may adjust the time periods in this paragraph [(e.g., the
one-year-from-institution deadline for final written deci-
sions)] in the case of joinder under [§] 315(c).” The Director
has delegated that time-adjustment authority to the Board.
37 C.F.R. § 42.100(c) (“An [IPR] proceeding shall be admin-
istered such that pendency before the Board after institu-
tion is normally no more than one year. The time can
be . . . adjusted by the Board in the case of joinder.” (em-
phasis added)). And that delegation is permissible for at
least two reasons. First, absent affirmative evidence of
contrary congressional intent (which CyWee hasn’t shown),
agency heads have implied authority to delegate to other
officials within the agency. See Ethicon Endo-Surgery,
812 F.3d at 1031–33. Second, Congress’s vesting of broad
rulemaking powers with the Director provides an alterna-
tive source of her authority to delegate. See id. at 1033
(citing 35 U.S.C. §§ 2(b)(2), 316(a)(4)).
CyWee nonetheless maintains that, because there was
no “right” for Director review of the Board’s extension deci-
sions, an Appointments Clause violation has occurred. See
Appellant’s Br. 22. If by “right” CyWee means that the Di-
rector had no right to review those decisions, CyWee is
plainly mistaken: “as a matter of law, the usual rule is that
an agency head’s delegation of her authority to subordi-
nates is premised, at least in part, on the delegating official
maintaining the power to review the decisions of the dele-
gee.” In re Palo Alto Networks, 44 F.4th at 1375 n.3
(cleaned up). And if by “right” CyWee means that there
was no right for it to seek or obtain Director review, even if
it were correct on that score, that also would not give rise
to an Appointments Clause violation. “[T]he Appointments
Clause was intended to prevent unappointed officials from
wielding too much authority, not to guarantee procedural
rights to litigants, such as the right to seek rehearing from
the Director.” Piano Factory Grp., Inc. v. Schiedmayer Ce-
lesta GmbH, 11 F.4th 1363, 1374 (Fed. Cir. 2021); see also
In re Palo Alto Networks, 44 F.4th at 1376 (observing that
Case: 20-1565 Document: 153 Page: 9 Filed: 02/08/2023
CYWEE GROUP LTD. v. GOOGLE LLC 9
language in Arthrex “strongly suggests that delegation to
the Board of the authority to decide on institution without
a mechanism for parties to subsequently request Director
review does not present Appointments Clause problems”);
id. at 1375–77. 5
CONCLUSION
We have considered CyWee’s remaining arguments
and find them unpersuasive. For the foregoing reasons, we
affirm.
AFFIRMED
5 CyWee’s supplemental brief—ordered solely to as-
sess which arguments in its opening brief survived our
later-issued precedent—sought to add new arguments. In
particular, CyWee cited a U.S. Government Accountability
Office report dated July 21, 2022, and “request[ed] that it
be allowed to brief” an issue concerning alleged structural
bias at the Board. Appellant’s Supp. Br. 4–6. We deny the
request.
