According to CoinMeta, Flinn Artificial Intelligence Technology Co., Ltd. ( Flinn AI ) filed a lawsuit on Thursday in the U.S. District Court of Delaware, accusing Anthropic PBC and OpenAI OpCo of infringing upon its patents. The complaint alleges that Flinn AI claims the two companies have infringed five patents obtained by co-inventors Steven Flynn ( Steven Flinn ) and Naomi Mannipeni ( Naomi Moneypenny ), which date back to late 2015 and early 2016. These inventions are designed to protect neural network technologies based on attention mechanisms, which are a fundamental foundation of modern generative artificial intelligence systems. The complaint specifically mentions that Anthropic's Claude series of large language models continue to infringe upon these patents as new versions are released. Flinn AI points out that with the iteration of the Claude model, its system provides more advanced reasoning, retrieval, memory, and multimodal functions, all of which infringe upon the patents in question. In addition, Flynn also founded ManyWorlds Inc , and Mannipeni later joined that company as well.
