A U.S. Circuit judge ruled that Ross Intelligence, a defunct legal-research startup, was not permitted to copy Thomson Reuters content to train a competing AI-based legal platform, rejecting a fair-use defense. This marks the first federal appellate decision on fair use in AI copyright litigation, setting precedent in a question central to ongoing cases by OpenAI, Microsoft, Meta, and others. For financial institutions, this ruling materially increases legal and regulatory risk for any AI vendor whose training-data provenance rests on claimed fair use of third-party copyrighted content without explicit licensing.
