Aperçu du dossier

In a significant outcome for decentralized finance (DeFi) patent litigation, the U.S. District Court for the Southern District of New York dismissed Bprotocol Foundation’s patent infringement complaint against Universal Navigation Inc. — the company behind the widely used Uniswap Protocol — without prejudice. The February 13, 2026 closure of Case No. 1:25-cv-04214 followed Chief Judge John G. Koeltl’s February 10, 2026 Memorandum Opinion & Order granting the defendant’s motion to dismiss.

Filed May 20, 2025, the case centered on two U.S. patents allegedly covering core mechanics of automated market-making within DeFi protocols. The dismissal, resolved in just 269 days without reaching full merits adjudication, carries meaningful implications for blockchain patent assertion strategy, the enforceability of DeFi-related IP, and how courts analyze software-implemented financial protocol patents at the pleading stage.

For patent attorneys, IP professionals, and R&D teams operating in the rapidly evolving blockchain sector, this case offers critical lessons about litigation risk, claim drafting, and freedom-to-operate analysis.

Les parties

Brevets en cause

This landmark case involved two U.S. patents allegedly covering core mechanics of automated market-making within DeFi protocols. Both patents relate to core DeFi infrastructure: algorithmic methods enabling peer-to-contract token trading without intermediaries.

• • U.S. Patent No. 11,107,049 B2 — Automated token exchange and pricing mechanisms (AMM functionality)
• • U.S. Patent No. 11,574,291 B2 — Decentralized liquidity pool and protocol architecture innovations

Le verdict et l'analyse juridique

Résultat

Chief Judge Koeltl’s February 10, 2026 Memorandum Opinion & Order granted Universal Navigation’s motion to dismiss the complaint in its entirety. The formal judgment, entered February 13, 2026, ordered the action dismissed without prejudice, and the case was closed. No damages were awarded. No injunctive relief was granted or denied on the merits.

The specific legal grounds articulated in the Memorandum Opinion are detailed within the court’s record (available via PACER, Case No. 1:25-cv-04214, SDNY). The public docket reflects that dismissal followed briefing on the defendant’s motion, with the court resolving the matter on the face of the pleadings.

Analyse des causes du verdict

The case was filed as a straightforward patent infringement action. However, dismissal at the Rule 12 stage — before any discovery or claim construction — typically reflects one or more foundational pleading deficiencies. For DeFi protocol patents specifically, § 101 eligibility represents a persistent vulnerability. Courts applying the Alice two-step test have frequently found that abstract financial concepts implemented via software — even on blockchain infrastructure — fail to constitute patent-eligible subject matter without a demonstrably inventive technical concept. AMM pricing algorithms, liquidity pool mechanics, and token exchange methods occupy a legally contested zone where eligibility challenges carry significant force.

The without-prejudice nature of the dismissal suggests the court may have identified curable pleading deficiencies rather than an absolute bar — though whether Bprotocol will replead remains an open strategic question.

Signification juridique

This case contributes to a developing body of DeFi patent litigation precedent in federal district courts. Several dimensions merit attention:

• • Alice/§ 101 exposure for DeFi patents: Patent holders asserting blockchain and DeFi protocol claims face heightened scrutiny at the pleading stage.
• • Pleading standards post-Twombly/Iqbal: Courts now require detailed factual allegations connecting specific patent claims to specific accused product functionality.
• • Venue and judge selection: SDNY’s sophistication in financial technology disputes makes it a credible forum with rigorous pleading scrutiny.
