Sony Music and Warner sue Anthropic, alleging a “brazen campaign” of intellectual property theft

Summary

Sony Music Publishing, Warner Chappell, and other music publishers have filed a lawsuit against Anthropic and its co-founders, Dario Amodei and Benjamin Mann. The companies allege that the AI lab conducted a 'serious illegal torrent and data scraping campaign' to access copyrighted works for training Claude.

Why it matters

This lawsuit builds on the $1.5 billion ruling in the Bartz case. It targets the method of acquisition—specifically piracy—rather than just the use of copyrighted material. This increases the legal risks for how AI labs obtain training data. It also signals coordinated legal action within the music industry, potentially setting a precedent that could reshape data acquisition norms across the entire AI sector.

Highlights

• Anthropic was already ordered to pay $1.5 billion in damages in the Bartz case for pirated content.
• The new lawsuit specifically alleges that millions of books containing lyrics and sheet music were illegally torrented.
• The same legal team behind the Concord and Universal Music Group lawsuits is driving this action.

Critical take

The article repeats the publishers' inflammatory language ('serious', 'outright piracy') without providing independent verification or technical details on how the data was obtained. Anthropic's one-sentence denial is presented without any counter-evidence. This leaves the reader with a distinctly one-sided narrative.
