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.
