Internet reports that the developers behind Bancor have filed a patent infringement lawsuit against Uniswap Labs and the Uniswap Foundation, accusing them of illegally using its basic decentralized trading platform technology. The lawsuit was filed by the Bprotocol Foundation, a nonprofit organization that supported the development of the Bancor protocol, and LocalCoin Ltd., Bancor's original developer. The lawsuit has been filed in the U.S. District Court for the Southern District of New York, alleging that the Uniswap agreement is based on Bancor's patented Constant Product Automatic Market Maker (CPAMM) infrastructure. Bancor invented the CPAMM model in 2016 and developed a mechanism to support permission-free on-chain transactions through smart contracts. The agreement was released in 2017 with a white paper and a U.S. patent application filed. Bancor received two patents in the same year and launched the first CPAMM-based DEX. The lawsuit alleges that the original protocol launched by Uniswap in November 2018 used the same CPAMM design without authorization. Bancor accused Uniswap of "profiteering" by deploying its intellectual property without consent.
