Alphabet Shareholder Sues Sundar Pichai and 12 Others Over AI Training on Copyrighted Works, Including Music Tool Lyria

A shareholder derivative suit filed by Phil Rosen names Alphabet CEO Sundar Pichai and 12 other defendants, alleging that Google improperly trained its AI models — including Lyria, its music-generation tool — on copyrighted works. Because the suit is filed derivatively on Alphabet's behalf, any damages recovered would flow to the company rather than to Rosen personally.

The case adds to a growing wave of copyright litigation targeting the data practices behind large AI systems, and is notable for its focus on generative music AI alongside broader model training claims.
