Fastcase has filed a lawsuit in U.S. federal court against Canadian legaltech firm Alexi, alleging breach of contract, trade secret misappropriation, and trademark infringement. The complaint centres on a 2021 licensing agreement that Fastcase says barred redistribution of its legal database.
Fastcase claims Alexi trained AI models on its data, displayed Fastcase case law, and used its trademarks in ways that could imply affiliation. Alexi CEO Mark Doble disputes the allegations, calling them a misunderstanding timed to the recent Clio–vLex acquisition. The case comes amid intensifying competition in AI-driven legal research. No court schedule has been set.
