Appeals court rejects fair use for Ross’s AI training
It is the first US appeals ruling on AI training and copyright. The court’s reasoning is sealed for now, and the case involves a search tool, not generative AI.
A US appeals court on September 29 upheld a ruling that Ross Intelligence infringed Thomson Reuters’ copyright by using material from Westlaw’s legal summaries to train an AI search tool. It is the first US appeals ruling on whether AI training can be fair use. The 32-page opinion is sealed while the two sides propose redactions.
