  "summary": "A US appeals court has upheld a ruling in favor of Thomson Reuters in a copyright lawsuit against Ross Intelligence. The court rejected Ross' argument that its use of Thomson Reuters' material was fair use for AI training purposes.\n\nThomson Reuters had sued Ross Intelligence in 2020, alleging that the company had copied and misused thousands of headnotes from its Westlaw platform to train an AI-powered legal search engine. Ross Intelligence shut down its platform in 2021, citing the costs of the litigation.\n\nThe 3rd US Circuit Court of Appeals in Philadelphia made the ruling, which is the first of its kind in a US appeals court regarding copyright cases over AI training. According to Investing.com, the appeals court's reasoning for its decision is currently sealed.",
