Bancor received two U.S. patents for its CPAMM technology and launched the first CPAMM‑based DEX in 2017

Quotes that support claims

According to the May 20 announcement of the lawsuit, Bancor designed the technology in 2016 and patented it in January 2017. The technology underpins the “constant product automated market maker,” which involves using mathematics to add or withdraw resources from a liquidity pool. The application subsequently led to two issued patents.

Bancor, credited with inventing the CPAMM model in 2016, developed the mechanism to power permissionless onchain trades through smart contracts. The protocol released a whitepaper and filed U.S. patent applications in 2017. According to a May 20 press release, Bancor was granted two patents and launched the first CPAMM-based DEX that year.
