Thomson Reuters Wins Major AI Copyright Case: A Blow to Generative AI

Thomson Reuters has won a landmark AI copyright lawsuit against Ross Intelligence, a legal AI startup. The court rejected Ross's fair use defense, finding its intent was to compete with Westlaw. This ruling is a significant setback for generative AI companies, potentially impacting future cases. Many AI tools were trained on copyrighted material, and this decision suggests that the common fair use arguments may not hold up. While Ross Intelligence shut down in 2021 due to litigation costs, financially strong companies like OpenAI and Google are better positioned to withstand prolonged legal battles.
