Uniswap founder Hayden Adams publicly confirmed that Uniswap has prevailed in a patent lawsuit brought by entities linked to Bancor over the core automated market maker (AMM) pricing formula used in decentralized exchanges. The dispute centered on Bancor-related plaintiffs Bprotocol Foundation and LocalCoin Ltd., which claimed their 2017 U.S. patent covered the constant product market maker mechanism—commonly expressed as the formula x y = k—used to price and trade tokens in Uniswap liquidity pools. In his post on X, Adams thanked legal teams including Fund Defi, Solana Institute and the Uniswap Foundation, characterizing Bancor’s position as attempting to patent “first grade level math” for token pricing on a blockchain. The court dismissed the Bancor-side patent claims, finding that the asserted patents covered abstract ideas and did not qualify for protection under U.S. law, and that the infringement allegations did not meet the legal standard required for patent enforcement. Legal commentary around the ruling emphasizes that simple, widely known mathematical formulas underlying DeFi protocols are difficult to monopolize through patents, especially when implemented in open-source software. The decision is viewed as a significant win not only for Uniswap but for the broader DeFi ecosystem, reducing legal uncertainty for other projects using similar AMM models and reinforcing the principle that foundational mechanisms like constant product formulas remain part of the public domain rather than exclusive proprietary assets.
