The lawsuit was filed by the Bprotocol Foundation, a nonprofit supporting the development of the Bancor Protocol, and LocalCoin Ltd., Bancor’s original developer. The complaint, filed in the U.S. District Court for the Southern District of New York, alleges that Uniswap’s protocol is built on Bancor’s patented constant product automated market maker (CPAMM) infrastructure.

The lawsuit claims Uniswap’s original protocol, launched in November 2018, uses the same CPAMM design without authorization. Bancor alleges Uniswap has “profited greatly” by deploying its intellectual property without consent.
