A US appeals court on Tuesday upheld a ruling for information services company Thomson Reuters in its copyright dispute with former legal-research rival Ross Intelligence over Ross’ alleged misuse of copyrighted material to train an AI-powered legal search engine. The 3rd US Circuit Court of Appeals rejected Ross’ argument that its search engine made fair use of material from Thomson Reuters’ Westlaw platform, a first-of-its-kind ruling by a US appeals court in a wave of high-stakes copyright cases over AI training.Source: US appeals court upholds Thomson Reuters’ landmark win in AI training lawsuit
