Thomson Reuters Urges Third Circuit to Block Ross Intelligence’s Copyright Appeal
Thomson Reuters Centre GmbH has requested the U.S. Court of Appeals for the Third Circuit to deny Ross Intelligence Inc.’s attempt to reverse a key copyright ruling in a closely watched lawsuit concerning AI training practices.
