A landmark ruling in the United States has significant implications for startups in the AI and legal tech sectors. A federal judge ruled against the AI legal research startup Ross Intelligence, siding with Thomson Reuters in a case concerning the use of copyrighted headnotes from Westlaw to train Ross’ AI platform. This decision marks the first major copyright ruling against an AI company in the U.S., affecting over 39 similar lawsuits. The judge rejected Ross’ fair use defense, emphasizing the startup’s commercial motivations and lack of transformative use. This verdict could influence ongoing and future copyright disputes involving AI companies, such as OpenAI and Microsoft, who argue their generative AI models transform copyrighted content. The outcome is seen as a strong victory for copyright holders but also highlights the complexities of fair use regarding AI training data.
