Before L OURIE , R EYNA , and H UGHES , Circuit Judges.

H UGHES , Circuit Judge

. This case presents three Administrative Procedure Actchallenges involving the United States Patent and Trademark Office . Odyssey challenge s procedural actions taken by the PTO in two patent applications and makes a third facial challenge to certain PTO procedural rules governing practice before the Patent Trial and Appeal Board in ex parte appeals

. The Eastern District of Virginia dismissed the former two challenges for lack of subject matter jurisdiction because the PTO had not taken final agency action

. It dismissed the latter challenge as barred by 28 U .S.C. § 2401, the six

- year statute of limitations for challenges to agency action. Because we agree with the district court that the first two challenges concern non

- final agency action and the latter challenge is barred by § 2401 , we affirm.

I
Odyssey L ogistics and Technology Corp oration (Odyssey)

, disapproving of certain decisions of the PTO, challenged the legality of those PTO decisions in district court under the Administrative Procedure Act (APA) . The first challenge (Count I) relates to the prosecution of U.S. Patent Application No. 11/005,678. The second challenge (Count II) relates to the prosecution of U.S. Patent Application No. 11/465,603. The third c hallenge (Count III) contests whether amendments to the Rules of Pract ice Before the Board of Patent Appeals and Interferences in Ex Parte Case: 19-1066 Document: 47 Page: 2 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 3

Appeals conform with the PTO’s statutory authority

. 1 See Rules of Practice Before the Board of Patent Appeals and Interferences in Ex Parte Appeals , 76 Fed. Reg. 72,270 (Nov. 22, 2011) ( codified at 37 C.F.R. pt s. 1 and 41)

. Werecount the factual and procedural history of each challenge in turn.

A

Count I arises from the examination of Odyssey’s ’678 patent application. Odyssey filed the ’678 application in 2004

. After a number of procedural disputes over the examination of the application, including multiple appeal s to this Court, see In re Riggs

, 457 F. App’x 923 (Fed. Cir. 2011) ; Odyssey Logistics & Tech. Corp. v. Kap pos , No. 11

- 1441 (Fed. Cir. filed June 20, 2011) (voluntarily dismissed)

, the Patent Trial and Appeal Board heard Odyssey’s appeal of the examiner’s rejections in the ’678 application. On April 29, 2016, the Board reversed the examiner’s rejections

. J.A. 1225, 1 229

– 30. The PTO did not, however, issue Odyssey a notice of allowance for the ’678 application

. Instead, on Sept ember 23, 2016, the Technology Center Director issued what Odyssey refers to as the “examiner’s request for rehearing.” 2 Appellant’s Br. at 14; J.A. 1267. The rehearing request argued that the Board had applied

1 These rules refer to the Board of Patent Appeals and Interferences because they were promulgated before the America Invents Act replaced the BPAI with the Patent Trial and Appeal Board on September 16, 2012. See Leahy

Smith America Invents Act, Pub. L. No . 112

- 29, §§ 7, 35, 125 Stat. 284, 313, 341 (Sept. 16, 2011) (codified as amended at 35 U.S.C. § 6). Because the relevant eventshere occurred after that date, we refer to the deciding administrative body as the Patent Trial and Appeal Board.

2 The PTO us es “rehearing” to describe “reconsideration.” 37 C.F.R. § 41.2. Case: 19-1066 Document: 47 Page: 3 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 4

an incorrect version of 35 U.S.C. § 102(e) to determin e whether a reference qualified as prior art and also requested clarification as to which claims the Board was reversing . J.A. 12 69

– 72. Odyssey was given the opportunity to respond to the rehearing request both before and after the Board received it. See J.A. 1282, 13 71

. O n both occasions, Odyssey did not address the merits of the examiner’s arguments, instead o bjecting to the procedural propriety of the rehearing request

. See id. Odyssey also filed petitionsobjecting to the rehearing procedure, and requests for reconsideration when those petitions were dismissed. J.A. 1326, 1334, 1357, 1360, 13 62

. Odyssey e ventually made some arguments on the merits “under protest,” J.A. 1370, but instead of waiting for the Board’s decision on these arguments , Odyssey filed this challenge to the request for rehearing in the Eastern District of Virginia.

B

Count II arises fr om the prosecution of Odyssey’s ’603 application. Odyssey filed the ’603 application in 2006. After a final rejection of all claims of the ’603 application

, Odyssey appealed the examiner’s rejections and, at the same time, filed a petition demanding that the examiner make certain evidence part of the written record and supplement his responses to Odyssey’s arguments with additional explanation . J.A. 1805, 1816; J.A. 1858. The examiner responded

, declining to include the additional evidence but further explaining his disagreement with Odyssey’s arguments for allowance . B ecause the examiner had responded, the Technology Center Director d ismissed the petition as moot.

With th is petition resolved, t he examiner filed hi s answer to Odyssey’s appeal brief . The examiner’s answer did
not desig nate any new grounds of rejection

, see J.A. 187 6

, but Odyssey believed that the answer included new grounds, so Odyssey filed a new petition, requesting that the Technology Center Dire ctor designate certain portions Case: 19-1066 Document: 47 Page: 4 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 5

of the examiner’s answer as new grounds of rejection . J.A. 1894. T he Technology Center Director dismissed this petition on the merits, finding that the portions of the answer with which Odyssey took issue did not set forth new grounds of rejection

. J.A. 1910

– 1 3

. Rather than filing a brief replying to the examiner’s answer and waiting to see if the Board would strike certain portions of its reply as improper, Odyssey challenged the dismissal of the petition in the Eastern District of Virginia

. C

Count III arises from the PTO’s 2011 amendments to its rules of practice in ex parte appeals

. See 76 Fed. Reg. 72,270

. The PTO gave four purposes for these amendments: (1) “to ensure that the Board has adequate information to decide ex parte appeals on the merits, while not unduly burdening appellants or examiner s with unnecessary briefing requirements”; (2) “to eliminate any gap in time from the end of briefing to the commencement of the Board ’ s jurisdiction”; (3) “to clarify and simplify petitions practice on appeal”; and (4) “to reduce confusion as to which cla ims are on appeal.” Id. at 72,27 1

. The PTO first published the amendments as a notice of proposed rulemaking in the Federal Register on Nov. 15, 2010. Rules of Practice Before the Board of Patent Appeals and Interferences in Ex Parte Appeals

, 75 Fed. Reg. 69,828 ( proposed Nov. 15, 2010)

. The final rules were published on Nov. 22, 2011. See 76 Fed. Reg. 72,270

. The amendments apply to all ex parte appeals filed on or after Jan uary 23, 2012. Id. Odyssey challenged th e legality of these amendmen ts , framing this C ount as a “facial” challenge to the 2011 amendments. See J.A. 31

– 32 , 45.

II
In the district court, the PTO moved to dismiss all three counts. It argued that the district court lacked subject matter jurisdiction for the first two counts, and that the third count was barred by the statute of limitations. Case: 19-1066 Document: 47 Page: 5 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 6

Odyssey opposed the dismissal of Counts I and III . Odyssey conceded that Count II should be dismissed but urged that it should be dismissed as moot under this Court’s intervening decision in In re Durance

, 891 F.3d 991 (Fed. Cir. 2018) , rather than for lack of subject matter jurisdiction

. See J.A. 1986.

The district court agreed with the PTO and dismissed all three counts. The court dismissed t he first two counts because Odyssey was challenging actions not yet final before the Board ; the Board could provide Odyssey with anadequate remedy, and if not, Odyssey had statutory remedies for appeal under 35 U.S.C. §§ 141 or 145 . The court held altern atively that it lacked a final agency action that would provide jurisdiction under § 704 of the APA

. The
court did not address mootness, noting that doing so would require it to “ rule substantively on whether the recent decision in the Federal Circuit in the Durance case ” applied
to Count II. J.A. 199 6

. The district court dismissed Count III, holding that 28 U.S.C. § 2401 barred the claims. J.A. 1997. The court held that Hire Order Ltd. v. Marianos , 698 F.3d 168, 170 (4th Cir. 2012), require s the statute of limitation s for a facial APA challenge to run from the date the regulations were published. Because the amended ex parte appeal regulations were published on Nov ember 22, 2011, and the complaint was filed on Jan uary 23, 2018 (six years aft er the effective date rather than the publication date ), the statute of limitations had run. J.A. 1997. T he district court held that , even if construed as an as

- applied challenge, it lacked subject matter jurisdiction to decide the challenge because, wit hout final agency action, the challenge could still be raised in the ongoing Board proceeding.
Odyssey timely appealed. We have jurisdiction under 28 U.S.C. § 1295(a)(1). Case: 19-1066 Document: 47 Page: 6 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 7

III
We review procedural rules following “the rule of the regional circuit, unless the issue is unique to patent law and therefore exclusively assigned to the Federal Circuit .” Madey v. Duke Univ. , 307 F.3d 1351, 1358 (Fed. Cir. 2002). APA claims against the PTO “raise[] a substantial question of patent law.” Exela Pharma Scis., LLC v. Lee , 781 F.3d 1349, 1352 (Fed. Cir. 2015). We “review [] de novo the district court’s dismissal of [a plaintiff’s] APA claims against the PTO for lack of subject matter jurisdiction.” Pregis Corp. v. Kappos , 700 F.3d 1348, 1354 (Fed. Cir. 2012 )

. As
to procedural questions not relating to patent law, t heFourth Circuit “review[s] the district court’s grant of a motion to dismiss de novo, focusing only on the legal sufficiency of the complaint.” McCauley v. Home Loan Inv. Bank, F.S.B. , 710 F.3d 551, 554 (4th Cir. 2013).

A
We first address whether Odyssey satisfied the APA ’s finality requirement

, see 5 U.S.C. § 704, for judicial review of Count I, Odyssey’s challenge to the Examiner’s Request for Rehearing in the ’678 appeal. On appeal, Odyssey argues that the Board’s reversal of the examiner’s rejections in the ’67 8 appeal was a final agency action, and the rehearing proceedings are an ultra vires action by the PTO.Odyssey characterizes the rehearing as a second Board proc eeding and urges us to consider the Board’s rehearing as an “attempted end

- [ run ] around the inability of the PTO” to directly appeal the Board’s decision. Appellant’s Br. 3 1

. We disagree.
In the context of the APA, “ an action is final if it both (1) mark [s] the consummation of the agency’s decisionmaking proces s and (2) is one by which rights o r obligations have been determined, or from which legal consequences will flow.” Smith v. Berryhill , 139 S. Ct. 1765, 1775

– 76 (2019) ( internal quotations omitted ) (first alteration in original) . Until the Board issues its rehearing decision, the Case: 19-1066 Document: 47 Page: 7 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 8

PTO has not consummated its decision

- m aking process and Odyssey’s rights and obligations in the ’678 patent have not been determined. Without such final action from the PT O, the APA does not entitle Odyssey to judicial review.
The rehearing process here is ordinary agency action in accordance with the PTO’s Manual of Patent Examining Procedure

. See M.P.E.P. 1214.04. 3 During a rehearing, t he Board continues to consider the validity of an application’s claims

. A lthough it found the claims allowable during the ’678 application’s appeal, the Board may reconsider its decision when the examiner requests rehearing. Id. See also In re Alappat , 33 F.3d 1526, 1531 (Fed. Cir. 1994), abrogated on other grounds by In re Bilski , 545 F.3d 943 (Fed. Cir. 2008) (allowing the Director to designate members of the Board to rehear a Board decision after the examiner requested rehearing under MPEP 1204.04); Applicati on of Schmidt , 377 F.2d 639, 641 (C.C.P.A. 1967) (“While requests for reconsideration by examiners are rare, it has been the settled practice to entertain them

. . . .”). Under the APA, “[t] he timely filing of a motion to reconsider renders the underlying order nonfinal for purposes of judicial review. ” Stone v. I.N.S. , 514 U.S. 386, 392 (1995)

. The

3 Under MPEP 1214.04, “[t] he examiner may request rehearing of the Board decision. Such a request should normally be made within 2 months of the return of the application to the [Technology Center]

. . . .” Calling the request the “examiner’s” is somewhat of a misnomer: “A ll requests by the examiner to the Board for rehearing of a decision must be approved by the [Technology Center]

. . . D irector and must also be forwarded to the Office of the Deputy Commissioner for Patent Examination Policy for approval before mailing. ” Id. The request is entered in the electronic file and “mailed or given to the” applicant, who has two months to reply before the request is forwarded to the Board. See id. Case: 19-1066 Document: 47 Page: 8 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 9

reconsideration process is the last stop on the PTO’s path to a final disposition, after which, if the Board does reverse itself, Odyssey will have an “adequ ate remedy in court” by appealing the Board’s decision under 35 U.S.C. §§ 141 or 145. See 37 C.F.R. § 90.3(b)(1) (explaining that the applicant’s time to challenge a Board decision in an appeal or civil action starts anew after the Board’s action on rehearing) ; c f. Automated Merch. Sys., Inc. v. Lee , 782 F.3d 1376

, 1381 (Fed. Cir. 2015) (finding no final agency action in asuit challenging the PTO’s refusal to terminate reexamination proceedings despite the request of the patent owner).
In Odyssey’s view, MPEP 1214.04 cannot apply because the examiner’s request for rehearing did not occur within 63 days, and, according to Odyssey, the Board loses jurisdiction 63 days after it issues its final decision , and these regulations must supersede PTO procedur al guidelines from the MPEP . Appellant’s Reply Br. 15

– 1 7 ; (citing 37 C.F.R. §§ 41.52

, 41.35(b)(2) )

. See also 37 C.F.R. § 90.3 (requiring than an applicant appeal a Board decision under § 141 or § 145 within 63 days)

. But neither § 41.52 nor § 41.35(b)(2 ) constrict the Patent Office’s time to request rehearing; they instead bind the patent applicant. E.g.

, 37 C.F.R. § 41.52 (a)(1) (“ Appellant may file a single request for rehearing within two months of the date of the original decision of the Board

. ” (emphasis added) ). Instead, the regulatory context suggests that the Director may override the Board’s “jurisdiction” so long as he does not circumvent eventual Board review. See 37 C.F.R. § 41.35 (“ Prior to the entry of a decision on the appeal by the Boar d , the Directormay sua sponte order the proceeding remanded to the examiner. ” (internal cross

- reference omitted)) ; Hyatt v. U.S. Pat. & Trademark Off. , 904 F.3d 1361, 1375 (Fed. Cir. 2018) (“ Allowing examiners to reopen prosecution does not deprive ap plicants of their right to appeal final examinerrejections because reopening prosecution cannot circumvent PTAB review. ”)

, cert. denied sub nom. Hyatt v. Iancu

, 140 S. Ct. 45 (2019)

. Case: 19-1066 Document: 47 Page: 9 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 10

If the Director may divest the Board of its authority over an appeal s o long as he does not circumvent the applicant’s statutory right to appeal

, the Director logically also may grant the Board authority to reconsider its appeal

. Issuing a request for rehearing under MPEP 1214.04 simply makes use of the Director’s authority over the examination

process under 35 U.S.C. §§ 131, 132. See M.P.E.P. 1002.02 (delegating the Director’s authority to approve “[r]equests from the examiner for

. . . rehearing of a [Board] decision” to the Deputy Commissioner for Patents ).

In s ome circumstances, the PTO’s d elay in making a request for rehearing , although technically conforming with the statute and regulation, may cause unfair prejudice to the applicant of such gravity that an applicant may seek otherwise

- premature recourse in th e courts

. Hyatt

, 904 F.3d at 1375 (“[T] he APA offers a remedy for [abusive use of agency rules to delay proceedings] by enabling reviewing courts to compel agency actions unlawfully withheld or unreasonably delayed without adequate reason or justification

. ”) But nothing indicates that such abusive action took place here

. I f Odyssey did encounter any unfair prejudice, it may raise the issue after the Board has reached a final decision. And if Odyssey prevails before the Board, it can seek appropriate Patent Term Adjustment to compensate for any delay. See 35 U.S.C. § 154(b)(4).

B

We next address whether Odyssey met the final agency action requirement for Count II, Odyssey’s challenge to the PTO’s dismissal of its petition ’603 application

, or whether Count II should have been instead dismissed as moot under Durance

. W e affirm the district court’s resolution of C ount II . The d ismissal of Odyssey’s petition to designate new grounds is non

- final agency action because the dismissal did not determine any rights o r obligations or result in any legal consequences. Until the Board refuse s to consider arguments made in Odyssey’s reply brief for Case: 19-1066 Document: 47 Page: 10 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 11

exceeding the permissible scope of the brief under 37 C.F.R. § 41.41, the denial of Odyssey’s petition to designate new grounds h as not determined any rights or resulted in any legal consequences

. 4 The district court was therefore correct to dismiss Count II for lack of finality.

T he district court was not obligated to dispose of the

case on the more uncertain mootness ground

— or even consider it

. “[A] federal court has leeway to choose among threshold grounds for denying audience to a case on the merits.” Sinochem Int ’ l Co. v. Malaysia Int ’ l Shipping Corp. , 549 U.S. 422, 431 (2007) (internal quotation marks omitted) ; see Long Term Care Partners, LLC v. United States , 516 F.3d 225, 233 (4th Cir. 2008) (upholdin g the district court’s dismissal of a case on APA finality grounds without reaching a “ difficult to resolve ” standing issue).The district court did not err by “tak[ing] the less burdensome course.” Sinochem , 549 U.S. at 436.

C
Finally, we turn to whether the district court properly dismissed Odyssey’s facial challenge to the PTO’s 2 011

ex parte appeal amendments because the statute of limitations had run. Odyssey argues that the statute of limitations governing facial challenge s of agency regulations

4 A lthough the district court appropriately declined to reach how Durance may or may not apply to the ’603 appeal, Durance is instructive in showing that other litigants understood the correct process to raise an APA challenge to the PTO’s failure to designate new grounds of rejection. In that case, the appellants submitted a reply brief containing the arguments they wanted to make,waited for the final decision of the Board, requested rehearing, and only then turned to the courts for judicial review of the agency action. See In re Durance , 891 F.3d 991 , 999

– 1000 ( Fed. Cir. 2018)

. Case: 19-1066 Document: 47 Page: 11 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 12

under 28 U.S.C. § 2401 starts on the effective date of the regulations, not the published date. Odyssey urges us to ignore as dictum the Fourth Circuit’s statement to the contrary in Hire Order

, 698 F.3d at 170

, and to apply Preminger v. Sec ’ y of Veterans Affairs , 517 F.3d 1299, 1307 (Fed. Cir. 2008)

, which , in its view, suggests that the effective date provides the correct rule. Appellant’s Br. 35

– 36; Appellant’s Reply Br. 24

– 27. Odyssey argues that Hyatt, 904 F.3d at 1372

, confi rms this conclusion because it makesa substantive facial challenge to the rules’ statutory compliance and therefore, under Hyatt

, 

### “ the right of action accrued from the first adverse application of the amended rules against Odyssey, which could not have been any earlier than the effective date of the amended rules. ” Appellant’s Br. 38. We disagree with Odyssey on all fronts

. The district court’s decision is unquestionably correct under Hire Order

. Odyssey characterized Count III as a facial chall enge in its amended complaint , J.A. 45, and requested a remedy that would go beyond any applications of the contested rules to its appeals. J.A. 48. Odyssey does not retreat from that characterization before this Court. See Appellant’s Br. 34, 38; Appel lant’s Reply Br. 27. Under Hire Order

, for “a facial challenge to an agency ruling [,]

. . .the limitations period begins to run when the agency publishes the regulation.” Hire Orde r , 698 F.3d at 170 (internal quotation marks omitted)

. The challenged rules were published in the Federal Register on November 22, 2011; Odyssey filed its facial challenge on January 23, 2018, more than six years later. J.A. 1997. Count III is therefore barred by 28 U.S. C. § 2401.

We need not decide whether this rule is a dict um , because the other authority Odyssey cites leads to the same conclusion. Hyatt definitively sets out the rule applied by this Court , which accords with Hire Order for f acial

, Case: 19-1066 Document: 47 Page: 12 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH

. v. IANCU 13

substantive challe nge s like that raised here

. 5 Under Hyatt
, the statute of limitations for a challenge to the PTO’s statutory authority to promulgate a regulation begins running “ either when the agency makes its initial decision or at the time of an adverse application of the decision against the plaintiff, whichever comes later. ” Hyatt , 904 F.3d at 1372

. The nature of Odyssey’s challenge, being a facialchallenge, means that it does not assert any adverse applications or seek relief in any specific applications. Cf. Educ. Media Co. at Va. Tech, Inc. v. Insley , 731 F.3d 291, 298 n.5 (4th Cir. 2013) (“[A] court considering a facial challenge isto assess the constitutionality of the challenged law without regard to its impact on the plaintiff asserting the facial challenge. In contrast, an as

- applied challenge is based on a developed factual record and the application of a statute to a specific person[.] ” (internal quotation marks and citation omitted; second alteration original)).

5 Numerous courts of appeal have held similarly to Hire Order and Hyatt that the statute of limitations for a substantive facial challenge to a regulation runs from the date of publication. See Rodriguez v. United States , 852 F.3d 67, 82 (1st Cir. 2017) ; Dunn

–McCampbell Royalty Interest, Inc. v. Nat ’ l Park Serv. , 112 F.3d 1283, 1287 (5th Cir. 1997); Wind River Min. Corp. v. United States , 946 F.2d 710, 715 (9th Cir. 1991); Pub. Citizen v. Nuclear Reg. Comm’n , 901 F.2d 147, 152 (D.C. Cir. 1990); see also Comanche Nation of Oklahoma v. Zinke , 754 F. App’x 768, 772 (10th Cir. 2018) ( explaining that “ [p] ublication in the federal regist er generally starts the limitations period for facial challenges ” of a regulation and noting

— based on Wind River , from which Hyatt also drew reasoning

— tha t timing of the statute of limitations based on an “adverse application” of a regulation is inapplicab le to a substantive facial challenge )

. v. IANCU 14

Without any adverse applications , the statute of limitations must accrue “when the agency makes its initial decision.” Hyatt , 904 F.3d at 1372. T hat decision is coterminous with the final agency action, which occurs when the agency promulgate s the final regulation. See Franklin v. Massachusetts , 505 U.S. 788, 797 (1992) (“The core question [in determining whether an agency ac tion is final] is whether the agency has completed its decisionmaking process, and whether the result of that process is one that will directly affect the parties. ”). In no case would the agency’s “initial decision” regarding a regulation take place on the effective date of the regulation.
Hyatt also forecloses Odyssey’s arguments about Preminger

. Hyatt explains that Preminger involved a procedural challenge, which alone distinguishes it from this

case. Hyatt , 904 F.3d at 1372 (citing Preminger

, 517 F. 3d at 1307 ). In addition, Hyatt relies on Preminger for the rule that the relevant “final agency action” starting accrual of the statute of limitations for a procedural challenge is the promulgation of a regulation. Id. (citing Preminger

, 517 F.3d at 130 7 ).
Applying either Hire Order and Fourth Circuit law or Hyatt and Federal Circuit law , 28 U.S.C. § 2401 bars Count III. We therefore affirm the district court’s dismissal of Count III because the statute of limitations to challenge the ex parte appeal rules ha d run before Odyssey filed suit

. IV
We have considered the parties’ other arguments andfind them unpersuasive. Odyssey brought its two challenges to the PTO’s actions during its ex parte appeals too early and brought its challenge to the PTO’s ex parte appeal regulations too late. The district court’s dismissal of the former two challenges for lack of subject matter jurisdiction and of the latter challenge for failure to state a claim is Case: 19-1066 Document: 47 Page: 14 Filed: 05/22/2020ODYSSEY LOGISTICS AN D TECH
