Bancor is suing Uniswap for infringement of its DEX smart contract technology patent

The developers behind Bancor have filed a patent infringement lawsuit against Uniswap Labs and the Uniswap Foundation, accusing them of illegally using their underlying decentralized trading platform technology.
The lawsuit, filed in the US District Court for the Southern District of New York, alleges that Uniswap is based on Bancor's patented Constant Product Automated Market Maker (CPAMM) infrastructure.
Bancor invented the CPAMM model in 2016 and developed a mechanism to support permissionless on-chain transactions through smart contracts. The protocol published a white paper and filed a US patent application in 2017. Bancor received two patents in the same year and launched the first CPAMM-based DEX.
The lawsuit alleges that Uniswap's original protocol, launched in November 2018, used the same CPAMM design without authorization. Bancor accuses Uniswap of "profiteering" by deploying its intellectual property without consent.
