The complaint adds to a mounting docket of author and publisher claims that Anthropic trained its Claude models on pirated book text, testing how far last year's fair-use rulings for AI training actually extend once copying methods are in dispute. For data licensing markets, each new suit sharpens the incentive for AI labs to document provenance and pursue cleared datasets rather than risk statutory damages at scale.
According to Yahoo Finance, the case seeks $75 million in damages tied to the alleged use of unauthorized book copies.
