Uniswap Grabs Early Win as US Judge Dismisses Bancor Patent Lawsuit

A New York federal court has dismissed a patent infringement suit brought by Bancor-affiliated entities against Uniswap, finding that the asserted claims describe abstract ideas that are not eligible for patent protection under US law. Judge John G. Koeltl of the Southern District of New York granted the defendants’ motion to dismiss the complaint filed by Bprotocol Foundation and LocalCoin Ltd. The ruling, issued on February 10, leaves room for the plaintiffs to amend within 21 days; absent a timely amendment, the dismissal would become with prejudice. While the decision represents a procedural win for Uniswap, it does not resolve the merits of the underlying dispute, which centers on whether the decentralized exchange’s technology infringes patented methods for pricing and liquidity.

Key takeaways

• The court applied the Supreme Court’s two-step framework for patent eligibility and determined the challenged claims relate to an abstract concept—the calculation of currency exchange rates for transactions—rather than a patentable invention.
• Even though the patents touch on blockchain-based automation, the judge found no inventive concept sufficient to transform the abstract idea into a patent-eligible application.
• The complaint was dismissed without prejudice, giving Bprotocol Foundation and LocalCoin Ltd. a 21-day window to file an amended complaint addressing the court’s concerns.
• Direct infringement, induced infringement, and willful infringement claims were all dismissed, with the court indicating the plaintiffs failed to plausibly plead that Uniswap’s code contains the patented reserve-ratio features.
• Despite the procedural success for Uniswap, the door remains open for reassertion if the plaintiffs can reframe the allegations to meet the patent-eligibility standard or otherwise articulate a viable infringement theory.

Market context: The ruling sits within ongoing debates over software and business-method patents in crypto, where courts have repeatedly scrutinized whether blockchain-enabled pricing and liquidity mechanisms constitute protectable inventions or abstract financial practices.

Sentiment: Neutral

Market context: The decision comes amid a broader climate in which courts assess blockchain-related claims under established tests for patent-eligibility, potentially influencing how crypto developers approach IP risk and claims enforcement.

Why it matters

The court’s analysis reinforces the notion that merely applying a conventional pricing algorithm within a blockchain framework may not suffice to render a claim patentable. By characterizing the disputed concepts as abstract ideas tied to currency exchange calculations, the ruling underscores the enduring legal distinction between mathematical formulas and patent-eligible tech implementations, even when those implementations run on decentralized networks. For Uniswap (CRYPTO: UNI), the decision protects the platform from an immediate patent-ownership challenge rooted in fundamental pricing logic that was already broadly implemented across digital asset exchanges.

From Bancor’s perspective, the dismissal—without prejudice—creates a strategic opening. The plaintiffs can attempt to adjust the pleading to address the court’s concerns, potentially reframing the claims to emphasize an “inventive concept” or to articulate a more concrete, non-abstract application tied to a particular technology environment. The outcome may influence later filings against other DeFi protocols if claim language can be refined to meet the legal standard, especially in cases where developers claim that specific programmable constraints or reserve mechanisms are patentable because they are uniquely tied to a given protocol.

Beyond the parties involved, the decision signals how the U.S. patent system balances the protection of crypto innovations against broad, abstract financial techniques. While it does not close the door on all IP actions in DeFi, it does remind developers and litigants that the mere use of blockchain infrastructure or smart contracts does not automatically render a broad abstract idea patent-eligible. The landscape remains nuanced, with the potential for future rulings to alter how similar claims are framed and prosecuted.

The immediate post-decision commentary from Uniswap founder Hayden Adams, who publicly celebrated the outcome, reflects the high-stakes nature of these disputes for open-source, community-driven projects. Adams’ brief social post—“A lawyer just told me we won”—highlights how patent battles intersect with developer culture and the public perception of DeFi innovation.

What to watch next

• Whether Bprotocol Foundation and LocalCoin Ltd. file an amended complaint within 21 days, and how the revised claims address the court’s abstract-idea reasoning.
• Any subsequent court rulings that interpret or apply the “inventive concept” standard to parallel DeFi patent cases, potentially shaping future strategy for both plaintiffs and defendants.
• Whether additional documents—such as claim charts or technical specifications—emerge to support allegations of infringement tied to Uniswap’s protocol code.
• Possible settlements or alternative dispute-resolution steps if parties seek to narrow the dispute without protracted litigation.

What the ruling changes for DeFi and IP strategy

Uniswap’s procedural win reinforces the importance of framing crypto innovations in terms of concrete technical improvements rather than broad economic practices. For developers, it underscores the need to articulate how a protocol’s specific architecture—beyond generic pricing formulas—contributes a novel, non-obvious technical solution. For plaintiffs, the decision emphasizes the necessity of tying claims to verifiable technical embodiments, such as particular code features or protocol configurations, that clearly differ from ordinary market operations.

What to watch next

Going forward, observers will closely track whether a revised complaint could survive the patent-eligibility hurdle and, if so, how the court will evaluate whether a claimed feature meaningfully transforms an abstract idea into patent-eligible subject matter. The interplay between public blockchain code and patented concepts is likely to remain a focal point as more DeFi projects navigate IP risk in a rapidly evolving regulatory and judicial environment.

Judicial decision reframes patent-eligibility in a DeFi dispute between Bancor-affiliated plaintiffs and Uniswap

In a decision that foregrounds the ongoing jurisprudence around crypto patents, a New York federal court ruled that Bancor-affiliated plaintiffs’ claims against the Uniswap ecosystem are directed to abstract ideas rather than concrete, patentable inventions. The Southern District of New York, applying the Supreme Court’s two-step framework for patent eligibility, concluded that the core concept—calculating currency exchange rates to facilitate transactions—lacks the inventive concept required to qualify for patent protection. The ruling focuses on US patent law’s limits, not on the operational legitimacy of Uniswap’s decentralized exchange (Uniswap), which remains a foundational player in the DeFi space.

The plaintiffs—Bprotocol Foundation and LocalCoin Ltd.—had alleged that Uniswap’s protocol infringed patents tied to a “constant product automated market maker” mechanism that underpins many liquidity pools on decentralized exchanges. The court’s analysis rejected the argument that merely implementing a pricing formula on blockchain infrastructure could overcome the abstract-idea hurdle. In its view, the use of existing blockchain and smart contract technologies to address an economic problem does not constitute a patentable invention. The court emphasized that limiting an abstract idea to a particular technological environment does not convert it into patent-eligible subject matter, and it found no further inventive concept that would transform the abstract idea into patentable territory.

Crucially, the memorandum explained that the asserted claims cover the abstract idea of determining exchange rates for transactions rather than a specific, novel technical improvement. The court highlighted that “currency exchange is a fundamental economic practice,” and that the claimed method amounted to nothing more than a mathematical transformation performed in a blockchain-enabled setting. The decision expressly notes that merely asserting a mathematical formula within a decentralized framework does not, by itself, generate eligibility. The ruling also rejected arguments that a particular linkage to reserve ratios in Uniswap’s code or ecosystem would rescue the claims from the abstract-idea category.

Beyond the abstract-idea assessment, the court dismissed the infringement theories levelled by the plaintiffs. It found that the amended complaint failed to plausibly plead direct infringement—specifically, that Uniswap’s publicly available code embodies the claimed reserve ratio constants. Claims of induced and willful infringement were likewise dismissed, with the court stating that the plaintiffs did not credibly show that Uniswap’s team had knowledge of the patents before the lawsuit was filed. The dismissal was without prejudice, preserving the option for the plaintiffs to file an amended pleading that could address these shortcomings.

The decision came with a notable public response: Hayden Adams, the founder of Uniswap, took to X to acknowledge the outcome, signaling a morale boost for developers and teams operating in the open-source DeFi space. The public posting underscored the practical impact of court rulings on the culture and momentum of decentralized finance development.

The procedural posture of the case remains in flux. While Uniswap’s legal team secured a favorable procedural ruling, the case is not over. The plaintiffs have 21 days to amend their complaint; failure to do so would convert the dismissal into one with prejudice, effectively ending the action barring any new claims. If Bancor and LocalCoin elect to proceed with an amended filing, the court will scrutinize whether the revised claims meet the patent-eligibility standard and sufficiently articulate any alleged infringement in a way that satisfies the pleading requirements set forth by the court.

In the broader context, the decision contributes to a growing body of decisions that caution against overbroad or abstract patent claims in the crypto and DeFi space. It reinforces the premise that software-driven financial concepts—however novel in a blockchain setting—must advance a concrete technical improvement to clear the patent bar. The outcome also signals that, for now, DeFi projects focusing on open, interoperable codebases may enjoy a degree of protection from aggressive patent assertions based on abstract pricing ideas, at least until a more precise standard for crypto-specific technology claims emerges in the courts.
