Bancor has filed a patent infringement lawsuit against Uniswap, alleging unauthorized use of its patented CPAMM technology for automated market making (AMM) within decentralized exchanges. The lawsuit, filed on May 20, 2025, in New York, highlights the complexities of intellectual property rights within DeFi and could significantly impact financial markets. Bancor claims that Uniswap has been operating under their patent since 2018 without explicit permission. The Bprotocol Foundation and LocalCoin Ltd., behind Bancor, emphasize the importance of protecting their innovations. The case involves major crypto entities with Bancor seeking damages from both Uniswap Labs and its foundation for potential financial gains from the violation. Both tokens, BNT (Bancor) and UNI (Uniswap), are at the center of these allegations. This lawsuit could influence the wider DeFi sector by emphasizing the need for clear legal frameworks regarding intellectual property in decentralized finance. Patent disputes in open-source crypto ecosystems are rare, potentially influencing protocols using similar technologies. The outcome of this case may set precedents, impacting future patent litigation and potentially reshaping regulatory landscapes within the space. – Mark Richardson, Project Lead, Bancor
