Wang v. Vidal (22-1510): Federal Circuit Affirms Sealed Bid Auction Patent Unpatentable
Kevin Sunlin Wang appealed the USPTO’s rejection of his sealed bid auction patent application (US14/967301) to the Federal Circuit, which affirmed the unpatentability finding after 915 days of proceedings. The ruling forecloses patent protection for Wang’s claimed method and system for sealed bid auctions at this application stage.
Federal Circuit closes the door on Wang’s sealed bid auction patent claim
Kevin Sunlin Wang filed appeal case 22-1510 on 4 March 2022, challenging the USPTO’s determination that his patent application US14/967301 — directed to a method and system for sealed bid auctions — was unpatentable. The defendants are Katherine K. Vidal, in her capacity as USPTO Director, and Andrew Hirshfeld. The case was heard by the United States Court of Appeals for the Federal Circuit, the specialist appellate court for all US patent matters.
On 4 September 2024, the Federal Circuit issued an affirmance, upholding the USPTO’s unpatentability finding. An affirmance at this level means the appellate panel found no reversible error in the agency’s analysis — the claimed invention as presented in US14/967301 remains unpatentable, and Wang’s application does not advance toward an issued patent. The basis of termination is recorded as ‘Unpatentable.’
The 915-day duration — filed March 2022, closed September 2024 — suggests the matter involved substantive briefing rather than a swift procedural resolution, though the specific grounds for unpatentability (e.g., § 101 subject matter eligibility, § 102 anticipation, or § 103 obviousness) are not detailed in the available public record. What drove the USPTO’s original rejection and the precise claims at issue remain matters for the underlying prosecution history. Wang’s further options at this stage — such as a petition for rehearing en banc or certiorari to the Supreme Court — face a significantly elevated bar.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means the Federal Circuit found no reversible error below
When the Federal Circuit affirms, it concludes that the USPTO’s decision — here, that application US14/967301 is unpatentable — was legally and factually sound. The appellate panel applies deferential review to factual findings and de novo review to legal conclusions. Affirmance does not necessarily endorse every line of the USPTO’s reasoning; it means the outcome survives appellate scrutiny. Wang’s application cannot proceed to issuance on these claims.
No reversible error foundWang’s sealed bid auction claims remain unpatentable after appeal
For Wang, the affirmance is a final adverse outcome at the Federal Circuit level. The claimed method and system for sealed bid auctions as embodied in US14/967301 will not issue as a US patent in their current form. Wang could theoretically seek en banc rehearing or petition the Supreme Court for certiorari, but both paths carry very low statistical success rates. Continuation or divisional applications with materially different claim language remain a theoretical — but uncertain — alternative route.
Application does not proceed to issuanceUSPTO’s patentability determination is fully vindicated at appellate level
The USPTO, represented by Director Vidal and Commissioner Hirshfeld, successfully defended its rejection across both the agency and appellate stages. This outcome reinforces the agency’s examination standards as applied to this class of invention — sealed bid auction systems — and signals that the examiners’ and PTAB’s analysis of the application’s shortcomings withstood the highest specialised patent appellate scrutiny available in the US system.
USPTO rejection upheldSealed bid auction technology space sees one fewer patent barrier
For companies operating in online auctions, procurement platforms, and e-commerce bid systems, the affirmance means US14/967301 will not create an enforcement risk. The ruling is consistent with the broader post-Alice trend of courts and the USPTO applying heightened scrutiny to method-and-system claims in financial and transactional technology. Competitors and platform developers working in sealed bid auction mechanisms can note that this particular claim set poses no future infringement exposure.

Official order — verbatim text
The single-word verdict ‘AFFIRMED’ with basis ‘Unpatentable’ indicates the Federal Circuit panel found no reversible error — legal or factual — in the USPTO’s rejection of US14/967301. At the appellate level, legal conclusions on patentability (including § 101, § 102, or § 103 determinations) are reviewed de novo, while underlying factual findings receive deference. An unqualified affirmance forecloses the application from proceeding to grant on the challenged claims, and the USPTO’s examination standards as applied to this sealed bid auction method are effectively endorsed by the court.
US14/967301 — Method and System for Sealed Bid Auctions
US patent application US14/967301 (published as US20160098788A1) claims a method and system for sealed bid auctions — a transactional technology domain spanning online procurement, real estate bidding, financial markets, and digital advertising. The application’s publication number suggests a filing in the mid-2010s timeframe, a period when the Supreme Court’s Alice Corp. v. CLS Bank decision (2014) was reshaping the patentability landscape for software and business method claims. The specific technical claims of the application are best assessed through the prosecution file history.
Sealed bid auction systems underpin significant commercial infrastructure across procurement platforms, government contracting, real estate, and programmatic advertising. A granted patent in this space would carry meaningful enforcement leverage. The Federal Circuit’s affirmance of unpatentability signals that the claim architecture as filed did not sufficiently distinguish the invention from abstract business method treatment — a challenge endemic to transactional software patents in the post-Alice era. For competitors and platform developers, this outcome removes one potential IP obstacle, though related family members or continuation filings should be independently evaluated.
Should you run an FTO analysis against US14/967301 and related applications?
Product and engineering teams building sealed bid auction functionality — whether for procurement platforms, ad-tech exchanges, real estate systems, or financial markets infrastructure — should note that US14/967301 itself poses no issuance risk following the Federal Circuit’s affirmance. However, FTO clearance for the broader technology space requires screening for any continuation, divisional, or continuation-in-part applications that Wang may have filed or that remain pending with differentiated claim language. The prosecution history of the US14/967301 family is the critical document to obtain.

What this case signals for the auction technology and fintech IP landscape
The Federal Circuit’s affirmance in Wang v. Vidal reinforces key lessons for patent applicants and IP teams in transactional technology.
Transactional method patents face a high bar at the Federal Circuit
The affirmance of unpatentability here is consistent with a sustained pattern of the Federal Circuit applying rigorous scrutiny to method-and-system claims in auction, financial, and e-commerce technology — particularly under § 101 subject matter eligibility doctrine post-Alice. Applicants in this space should ensure claims are tightly anchored to a concrete technical improvement, not a business method abstraction.
USPTO Director-level appeals carry institutional weight that is difficult to overcome
Cases where the USPTO Director is a named defendant signal that the agency’s institutional position on patentability is formally at stake. Federal Circuit panels typically afford deference to agency factual findings, making affirmance the statistically likely outcome in the absence of a clear legal error. IP teams advising clients on appeal should weigh this structural disadvantage before committing to Federal Circuit review.
WANG v Katherine — key questions answered
The Federal Circuit affirmed the USPTO’s unpatentability determination for patent application US14/967301 (method and system for sealed bid auctions) on 4 September 2024. The affirmance means no reversible error was found in the agency’s rejection, and the application will not proceed to grant on the challenged claims.
The patent at issue is US patent application US14/967301, published as US20160098788A1, which covers a method and system for sealed bid auctions. The application was rejected by the USPTO as unpatentable, and that rejection was affirmed by the Federal Circuit in September 2024.
Sealed bid auction claims typically involve transactional or business method steps, which have faced heightened scrutiny under the Supreme Court’s Alice Corp. v. CLS Bank (2014) decision. Under § 101, method claims directed to abstract ideas without a sufficient inventive concept — a concrete technical improvement beyond the abstract method itself — are routinely rejected. The specific grounds in this case are not detailed in the public record.
Following a Federal Circuit affirmance, Wang’s options include petitioning for rehearing en banc before the full Federal Circuit, or filing a petition for a writ of certiorari to the US Supreme Court. Both paths carry very low statistical success rates. Wang could also pursue continuation or divisional applications with materially different claim language at the USPTO, though the affirmance signals significant headwinds for the current claim architecture.
