USPTO Discretion in IPR Denials Confirmed by Federal Circuit in Apple v. Squires
The Federal Circuit’s decision in Apple Inc. v. Squires, Case No. 2024-1864 (Fed. Cir. Feb. 13, 2026) reinforces a powerful reality in modern patent litigation: the Director of the United States Patent and Trademark Office (“USPTO”) possesses broad discretion to deny institution of Inter Partes Review (“IPR”), even when a petition otherwise meets statutory thresholds.
For patent owners and challengers alike, this decision is not just procedural. It reshapes litigation strategy, forum selection, and the timing of patent challenges. It also signals continued judicial deference to agency authority under the Administrative Procedure Act (“APA”).
In practical terms, companies can no longer assume that filing a strong IPR petition guarantees review. Instead, discretionary denial has become a central strategic variable, particularly in cases involving parallel district court litigation.
What Is IPR and Discretionary Denial?
IPR is an administrative proceeding conducted by the Patent Trial and Appeal Board (“PTAB”) that allows third parties to challenge the validity of the claims of an issued patent. It is governed primarily by 35 U.S.C. §§ 311-319 and serves as a streamlined alternative to district court litigation for resolving certain patentability issues.
Key features include:
A focus on prior art patents and printed publications
A lower burden of proof than in district court (preponderance of the evidence rather than clear and convincing evidence)
A relatively expedited timeline, typically resulting in a final written decision within 12-18 months of institution
What Is Discretionary Denial?
Even when a petition satisfies the statutory threshold under 35 U.S.C. § 314(a) (i.e., a reasonable likelihood that at least one challenged claim is unpatentable) the USPTO Director, acting through the PTAB, retains discretion to deny institution. This authority reflects the agency’s role in managing its docket and ensuring efficient resolution of patent disputes.
Common discretionary denial considerations include:
The existence of parallel district court litigation proceeding on a similar or faster timeline
Concerns about duplicative proceedings and potentially inconsistent outcomes
Broader considerations of judicial and administrative efficiency
The PTAB has historically relied on policy frameworks such as the Fintiv factors, derived from the precedential decision in Apple Inc. v. Fintiv, Inc., IPR2020-00019, 2020 WL 2126495 (P.T.A.B. Mar. 20, 2020), to guide this analysis, particularly in cases involving parallel litigation. However, these frameworks are not mandated by statute and have evolved over time through USPTO guidance, Director review decisions, and shifts in administrative priorities.
The Primary Conflict Driving the Appeal
At the heart of the Apple Inc. case was a familiar but increasingly significant tension in patent law: whether the USPTO should institute an IPR when a parallel district court case involving the same patent is already progressing on a similar or faster timeline. Apple filed a petition for IPR challenging patents that had been asserted against it in ongoing district court litigation, presenting prior art arguments that appeared to satisfy the statutory threshold for institution under 35 U.S.C. § 314(a). That provision requires a showing that there is a reasonable likelihood that at least one challenged claim is unpatentable, serving as the gateway standard for PTAB review. However, despite meeting this threshold, the USPTO denied institution based on discretionary considerations tied to the parallel litigation, including the stage of the district court proceedings and concerns about duplicative adjudication across forums.
Apple challenged that denial, arguing that the agency had exercised its discretion too broadly in a manner that undermined the intended role of IPR proceedings. According to Apple, IPR was designed by Congress to function as an efficient administrative mechanism for reassessing patent validity, and the use of discretionary denial in cases where the statutory threshold is met weakens that function. Apple further contended that reliance on factors such as district court scheduling and litigation efficiency introduces uncertainty into the system, making it more difficult for petitioners to predict whether and when PTAB review will be available. The company also asserted that the denial was arbitrary and capricious under the APA, arguing that agency decision-making must be grounded in consistent and reasoned analysis rather than shifting policy considerations.
On the other side, the USPTO maintained that § 314(a) grants the Director substantial discretion in deciding whether to institute review, reflecting the agency’s responsibility to manage its docket and ensure efficient use of administrative resources. The agency emphasized that institution of IPR is not automatic upon satisfaction of the statutory threshold, but instead involves balancing competing institutional interests, including efficiency, fairness to the parties, and the avoidance of duplicative (or potentially conflicting) proceedings. In particular, the USPTO pointed to the risk that parallel district court and PTAB proceedings could result in unnecessary duplication of effort or inconsistent outcomes on the same patent claims. This dispute ultimately framed a broader legal question for the Federal Circuit: whether the USPTO’s discretionary authority under § 314(a) permits denial of institution even when the threshold showing is satisfied, and how that discretion should be reconciled with the statutory purpose of IPR and the broader goals of consistency, efficiency, and access to administrative patent review.
The Federal Circuit’s Decision
The Federal Circuit affirmed the USPTO’s authority to deny institution of inter partes review, emphasizing both the discretion afforded under 35 U.S.C. § 314(a) and the limited scope of judicial review under the APA. The court’s analysis reinforced the principle that institution decisions are committed largely to agency discretion and are subject to a highly deferential standard of review when judicial scrutiny is available at all.
The court made several key determinations:
Discretion Under § 314(a): The statute permits the Director to deny institution of IPR even where a petitioner demonstrates a reasonable likelihood of prevailing on at least one challenged claim. The statutory threshold establishes eligibility for consideration but does not create an entitlement to review.
Limited APA Review and Deference: Where review is available, the USPTO’s decision-making is evaluated under the “arbitrary and capricious” standard. In practice, however, Supreme Court precedent such as Cuozzo Speed Technologies v. Lee ,579 U.S. ____(2016) and Thryv, Inc. v. Click-To-Call Technologies, 590 U.S. ____(2020) significantly limits judicial review of institution decisions, reinforcing substantial deference to the agency.
Parallel Litigation as a Relevant Factor: The court recognized that the USPTO may consider the existence and posture of parallel district court proceedings when determining whether to institute review, including concerns related to efficiency, timing, and potential duplication of effort.
Consistency with the Statutory Scheme: The court rejected the argument that discretionary denial, in this context, is inconsistent with the structure of the inter partes review system, finding it compatible with the agency’s statutory authority to manage institution decisions.
What the Court Did Not Do
Importantly, the Federal Circuit did not:
Eliminate or invalidate discretionary denial frameworks used by the USPTO
Impose rigid or mandatory rules governing when institution must occur
Require uniform application of any specific multi-factor test across all cases
Instead, the decision preserves significant flexibility for the USPTO to adapt its institution practices through policy guidance and case-by-case adjudication, leaving continued room for administrative evolution in PTAB practice.
Current Landscape: Where Things Stand Now
Following the Federal Circuit’s decision in Apple Inc, the USPTO retains substantial flexibility in how it manages IPR petitions, particularly when parallel district court litigation is involved. The ruling reinforces a broader trend in patent law: institution decisions are not purely mechanical applications of statutory thresholds, but instead reflect a layered analysis that incorporates policy considerations and institutional priorities. As a result, both petitioners and patent owners must operate in an environment in which discretion plays a decisive role in whether review proceeds.
In practice, this has led to a more dynamic and, at times, less predictable PTAB landscape. The Director continues to influence outcomes through policy guidance, precedential decisions, and the evolving use of discretionary denial frameworks. While earlier decisions and guidance (e.g., those associated with Fintiv) attempted to formalize how parallel litigation should be evaluated, Apple Inc underscores the fact that these frameworks are not rigid rules. Instead, they function as flexible tools that the USPTO may apply, modify, or even deprioritize depending on broader administrative goals.
Several key dynamics currently define the post-Squires environment:
Petitioners face increased uncertainty regarding whether strong invalidity arguments will lead to institution, particularly when district court proceedings are advancing quickly.
District court scheduling (e.g., firm trial dates) continues to play an outsized role in discretionary denial analysis.
At the same time, the decision aligns with a series of Supreme Court and Federal Circuit rulings that collectively limit judicial review of institution decisions. Cases such as Cuozzo and Thryv, Inc. have already established that many institution-related determinations fall outside the scope of appellate review. Apple Inc builds on that foundation by reaffirming that even when review is available under the APA, courts will apply a highly deferential standard. This means that, in most cases, the USPTO’s reasoning will stand so long as it is rational and adequately explained, even if reasonable minds could disagree on the outcome.
For stakeholders, this evolving landscape requires a more integrated and forward-looking approach to patent disputes. PTAB proceedings can no longer be treated as a predictable backstop to district court litigation. Instead, they must be carefully coordinated with broader litigation strategy, taking into account timing, venue, and the likelihood that discretionary factors may ultimately control the outcome.
The USPTO’s institutional interest in efficiency and consistency increasingly shapes whether parallel proceedings are permitted to move forward.
Director-level oversight and policy adjustments remain a significant variable, meaning that PTAB practice may continue to evolve in response to leadership priorities and external pressures.
How Discretionary Denial Is Reshaping Patent Litigation Strategy
The Federal Circuit’s decision carries significant, real-world consequences across the patent ecosystem, particularly for how parties approach IPR and parallel litigation. What was once viewed primarily as a merits-driven process now requires a more nuanced, strategy-first mindset. Discretionary denial has evolved into a central feature of PTAB practice, forcing both challengers and patent owners to think beyond the strength of their legal arguments and consider timing and forum dynamics.
For Patent Challengers
For petitioners, the decision underscores that a strong invalidity case is no longer sufficient on its own. Instead, success increasingly depends on when and how a petition is filed in relation to ongoing litigation.
Key considerations now include:
Timing is Critical: Filing early (ideally before significant district court milestones) can materially reduce the likelihood of discretionary denial
Forum Coordination Matters: Petitioners must align PTAB filings with district court strategy, including venue selection and litigation pacing
Merits are Necessary, But Not Sufficient: Even well-supported petitions may be denied if discretionary factors weigh against institution
Predictability Remains Limited: Outcomes can vary depending on panel composition, Director guidance, and case-specific facts
As a result, petitioners are increasingly adopting proactive filing strategies and conducting earlier prior art investigations to preserve the option of PTAB review.
For Patent Owners
Patent holders, by contrast, may find themselves with additional strategic leverage in both litigation and negotiation contexts. The ability to influence discretionary denial outcomes, particularly through district court timing, can shift the balance of power.
In practical terms, patent owners can:
Accelerate district court proceedings to strengthen arguments against PTAB institution
Reduce exposure to administrative challenges in cases where litigation is already well underway
Use the risk of discretionary denial as leverage in settlement discussions
Shape the procedural narrative to emphasize efficiency and avoid duplicative review
This shift does not eliminate PTAB risk, but it does provide patent owners with more tools to manage when and how their patents are challenged.
For the Patent System Overall
At a systemic level, the decision reinforces the USPTO’s role as an active gatekeeper rather than a passive adjudicator. The agency’s ability to control its docket and prioritize efficiency has broad implications for how patent disputes are resolved in the United States.
Among the most notable effects:
Increased administrative control over PTAB workload and case selection
Ongoing tension between efficiency goals and broad access to patent validity review
Greater procedural complexity for parties navigating dual-track litigation
Continued evolution of PTAB policy through Director guidance and adjudicatory decisions
These developments suggest that the balance between administrative review and district court litigation will remain fluid, shaped as much by policy as by statute. The Apple Inc. decision highlights a fundamental shift in how IPR operates in practice. Rather than serving as an automatic forum for adjudicating patent claim validity, the PTAB now functions within a framework in which access itself is subject to meaningful gatekeeping. The Federal Circuit’s endorsement of broad USPTO discretion makes clear that procedural context, institutional priorities, and litigation posture can be just as decisive as the underlying merits.
For stakeholders across the innovation economy, this means that effective patent strategy must extend beyond legal arguments and incorporate timing, coordination, and foresight at every stage. Those who adapt to this reality will be better positioned to navigate disputes efficiently, while those who rely solely on traditional assumptions about IPR availability may find themselves at a strategic disadvantage.
