Expert rule: There are reviewable non-final agency actions

by Ian J. Howard | May 7, 2026 | Patents

In a decision addressing the scope of constitutional challenges to agency action, the US Court of Appeals for the District of Columbia Circuit affirmed a district court’s injunction barring an investigation by the US International Trade Commission premised on a protective order issued by an unconstitutionally appointed administrative law judge (ALJ). Sidak v. ITC, Case No. 23-5149 (D.C. Cir. Apr. 24, 2026) (Katsas, Rao, Walker, JJ.)

Gregory Sidak served as an expert witness in a 2017 Commission proceeding. During that proceeding, the presiding ALJ issued a protective order governing confidential information. At the time, ALJs were appointed unilaterally by the Commission’s chairman – a practice later called into question by the Supreme Court’s decision in Lucia v. SEC, which held that ALJs are “inferior officers” who must be appointed by the president, courts, or the “head” of a department. The Commission subsequently ratified the appointments of its ALJs but did not ratify their prior actions, including the protective order at issue.

Years later, the ITC initiated an investigation into whether Sidak violated that protective order. In response, Sidak filed suit in district court seeking to enjoin the investigation, arguing that the order was unenforceable because it had been issued by an improperly appointed ALJ and never ratified. The district court granted a permanent injunction, and the Commission appealed.

The DC Circuit affirmed, first addressing several threshold procedural issues. The Court determined that the district court had subject matter jurisdiction under 28 U.S.C. § 1331 because Sidak’s claim arose directly under the US Constitution. The Court explained that no applicable statutory review scheme displaced that jurisdiction for this type of claim, and that litigants may pursue equitable relief to enjoin unconstitutional agency action.

The DC Circuit also rejected the Commission’s argument that Sidak’s claim was unripe. Because the case presented purely legal questions regarding the enforceability of the protective order and Sidak faced a credible threat of sanctions, the dispute was both constitutionally and prudentially ripe. The Court further explained that final agency action is not required where a plaintiff brings an implied constitutional claim rather than a claim under the Administrative Procedure Act.

Turning to timeliness, the DC Circuit determined that Sidak had not forfeited his Appointments Clause challenge. Unlike a party that invokes an agency adjudication and seeks a ruling on the merits, Sidak was a third-party witness who neither initiated the underlying proceeding nor sought relief from the ITC. The Court emphasized that forfeiture principles apply differently in that context and that Sidak had no earlier opportunity or obligation to raise his claim.

On the merits, the DC Circuit affirmed the district court’s decision to enjoin the Commission’s investigation. The Commission did not dispute that the ALJ who issued the protective order had been improperly appointed or that the order had not been ratified. The DC Circuit concluded that the district court did not abuse its discretion by granting injunctive relief to prevent enforcement of an order lacking constitutional authority.

Finally, the DC Circuit rejected the Commission’s challenge [...]

Applicant-admitted prior art may inform but can’t be basis for IPR challenges

by Ashley K. Justice | Jul 24, 2025 | Patents

The US Court of Appeals for the Federal Circuit clarified that while applicant-admitted prior art (AAPA) may be cited as evidence of general background knowledge in inter partes review (IPR) proceedings, it cannot serve as the basis for an IPR ground. The Court also confirmed that the petitioner had Article III standing to cross-appeal based on concrete plans for future activity. Shockwave Medical, Inc. v. Cardiovascular Systems, Inc., Case No. 23-1864 (Fed. Cir. July 14, 2025) (Lourie, Dyk, Cunningham, JJ.)

Shockwave Medical owns a patent directed to treating atherosclerosis using a balloon catheter in combination with shockwaves generated by electrodes and a pulse generator. The patent specification acknowledged that “over-the-wire angioplasty balloon catheters” were well known in the art. Cardiovascular Systems, Inc. (CSI) filed an IPR petition asserting that it would have been obvious to modify a European patent application with the angioplasty balloon catheter disclosed in the AAPA.

The Patent Trial & Appeal Board found all but one claim unpatentable as obvious, relying on the AAPA solely as evidence of background knowledge. Both parties appealed.

Shockwave challenged the Board’s reliance on the AAPA, arguing that 35 U.S.C. § 311(b) prohibits using AAPA as a basis for an IPR petition. The Federal Circuit disagreed, reaffirming its prior decisions in Qualcomm I and Qualcomm II. In Qualcomm I, the Court explained that AAPA cannot be the basis of a ground in an IPR petition but can be evidence of background knowledge. In Qualcomm II, the Court found that the Board erred in determining that the use of AAPA was proper when the petitioner expressly included AAPA in one of its grounds. Relying on these decisions, the Court explained that while AAPA cannot form the basis of a ground in an IPR petition, it may be used to demonstrate the general knowledge of a person of ordinary skill in the art and to supply missing claim limitations.

Shockwave pointed to a table in the Board’s final written decision listing AAPA under “reference(s)/basis” as evidence that the Board improperly relied on AAPA as a ground. The Federal Circuit rejected this argument, distinguishing Qualcomm II and emphasizing that the petitioner, not the Board, defines the grounds for review. Because CSI did not rely on AAPA as a ground, its use was permissible.

CSI cross-appealed the Board’s finding that one claim was not obvious. Shockwave challenged CSI’s standing, but the Federal Circuit found that CSI had Article III standing because it had concrete plans to begin clinical trials and because of Shockwave’s public statements suggesting it would assert the patent. The Court concluded that these facts created a substantial risk of future infringement.

On the merits, the Federal Circuit agreed with CSI that the Board erred by failing to consider the prior art as a whole. The Court reiterated that the obviousness inquiry requires evaluating the combined teachings of the prior art, not individual references in isolation. Finding no evidence to support the Board’s conclusion, the Court reversed the Board’s decision as to the remaining [...]

Show Your Work: PTO Director’s Procedure for Issuing Instructions Is Reviewable

by Rodney Swartz, PhD | Mar 23, 2023 | Patents

The US Court of Appeals for the Federal Circuit affirmed the district court’s finding under the Administrative Procedure Act (APA) that the substance of the US Patent & Trademark Office (PTO) Director’s instructions is unreviewable but reversed the finding that the cloak of unreviewability extended to the procedure used in issuing the instructions. Apple v. Vidal, Case No. 22-1249 (Fed. Cir. Mar. 13, 2023) (Lourie, Taranto, Stoll, JJ.)

The creation of the inter partes review (IPR) program opened new avenues for reviewing the validity of patents following issuance. Since the program’s inception, Congress has recognized that there is a possibility of parallel proceedings at the Patent Trial & Appeal Board and in the district court, that such proceedings could result in conflicting decisions and reduced efficiency in the system. However, Congress left it to the discretion of the two branches to work out such situations among themselves.

As one lever to overcome these issues, Congress provided the Director with unreviewable discretion in deciding whether to institute an IPR. Recently, the Director attempted to leverage this power to increase efficiencies and reduce gamesmanship by instructing the Board on what to consider when instituting an IPR.

Apple and four other companies challenged these instructions in the district court. Apple argued that the Director’s instructions violated the APA by being contrary to the IPR provisions, arbitrary and capricious, and issued without the notice-and-comment rulemaking required under the APA.

Following a motion to dismiss, the district court concluded that Apple’s challenges were directed at the Director’s actions, making them unreviewable by the court. Apple appealed.

On appeal, the Federal Circuit considered all three of Apple’s APA challenges to the instructions, along with whether Apple had standing to bring the suit. The Court agreed with the district court that the question of whether an instruction violates the APA by being contrary to the IPR provisions or by being arbitrary and capricious is directed to the substance of the Director’s action and is not reviewable: “§ 314(a) invests the Director with discretion on the question whether to institute review . . . : The determination by the Director whether to institute an inter partes review . . . shall be final and nonappealable.” As the Federal Circuit noted, this conclusion rests on the well-supported need for the PTO Director to give guidance to delegatees on how to make institution determinations.

The Federal Circuit disagreed that the announcement procedure the Director used for issuing the instructions to the Board was unreviewable, however. As the Court noted, the procedure employed by an agency to announce guidelines is “quite apart” from the substance of those guidelines. Given this distinction, the Court concluded that the procedure the Director used to announce the instructions was reviewable: “The government here has not shown that anything in § 314(d) or elsewhere in the IPR statute supplies clear and convincing evidence that there was to be no judicial review of the choice of announcement procedure, a matter for which generally applicable standards exist.”

Shots Fired: Challenger Must Have Requisite Standing Before Appealing Unfavorable IPR Decisions

by Paul Devinsky | Dec 16, 2021 | Patents

The US Court of Appeals for the Federal Circuit found, in the context of an appeal from an inter partes review (IPR) decision, that the appellant had Article III standing and affirmed a Patent Trial & Appeal Board (Board) decision, holding the challenged claims unpatentable as obvious. ModernaTX, Inc. v. Arbutus Biopharma Corporation, Case No. 20-2329 (Fed. Cir. Dec 2, 2021) (Lourie, J.)

Arbutus owns a patent pertaining to “stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.” Moderna petitioned for IPR of the patent, asserting three grounds:

Moderna alleged that all claims of the challenged patent would have been anticipated and/or obvious in light of International Pat. Publ. WO 2005/007196 (‘196 PCT) or US Pat. Publ. 2006/0134189 (‘189 publication).
Moderna alleged that all claims of the challenged patent would have been obvious over a combination of the ‘196 PCT, the ‘189 publication, Lin and Ahmad.
Moderna alleged that all claims of the challenged patent were anticipated by US Pat. Publ. 2006/0240554 (‘554 publication), and alternatively that the claims would have been obvious over the ‘554 publication.

The Board rejected each of Moderna’s allegations, finding that the claims were not unpatentable as obvious. Moderna appealed.

Before addressing Moderna’s appeal on its merits, the Federal Circuit addressed whether Moderna had proper standing to challenge the Board’s decision. The Court stated that well-established precedent dictates that an appellant seeking review of a Board decision in an IPR must have suffered an injury in fact that is fairly traceable to the challenged conduct of the appellee and is likely to be redressed by a favorable judicial decision. The Court underscored that under IPR statute, there is no standing requirement for petitioners to request institution of IPR by the Board, meaning that a requester need not have a concrete stake in the outcome. Additionally, where the statue itself grants judicial review (such as in the case of an IPR), standing criteria of immediacy and redressability may be “relaxed.” Nonetheless, the Court explained that a party’s participation in the underlying IPR alone does not confer standing on that party to appeal the Board decision before an Article III court such as the Federal Circuit. The party seeking review (in this case Moderna) must show that it possesses requisite injury for standing to appeal.

Moderna asserted that substantial risk existed that Arbutus would bring an infringement suit against Moderna based on Moderna’s COVID-19 vaccine if the challenged patent was to remain valid. In support, Moderna submitted a declaration from its senior vice president and deputy general counsel that Moderna was working to harness proprietary mRNA technology and planned on releasing and applying for emergency use authorization for a COVID-19 vaccine in December 2020. The declaration also described how Arbutus’s conduct created a substantial risk that it would bring subsequent infringement action against Moderna. An example of such conduct was a series of public statements [...]
