Bancor has filed a lawsuit against Uniswap, alleging that the popular decentralized exchange unlawfully used its patented automated market maker (AMM) technology.
Bancor claims it developed and patented the “constant product AMM” model in 2016, with patents granted in 2017, and that Uniswap integrated this innovation without permission when it launched in 2018.

The lawsuit, filed in the U.S. District Court for the Southern District of New York, is led by the Bprotocol Foundation and LocalCoin, and seeks damages for Uniswap Labs’ alleged infringement, along with the Uniswap Foundation’s role in its promotion.
Mark Richardson, Bancor’s project lead, said the legal move was necessary to protect the DeFi industry’s integrity and prevent unchecked competition.
Market data highlights a stark contrast in reach: Uniswap processed around $3.8 billion in 24-hour trading volume, while Bancor lagged behind at just under $380,000, ranking 142nd.
