Sony Music Publishing and Warner Chappell have filed a lawsuit against Anthropic, alleging the AI company used tens of thousands of copyrighted songs without authorization to train its Claude AI models. The suit, filed in California, marks another major legal challenge in the ongoing battle over AI training data.
TL;DR
- Sony and Warner allege Anthropic used 10,000+ copyrighted songs, including works by major artists, to train Claude AI models.
- The lawsuit could expose Anthropic to billions in damages, with potential claims of up to $150,000 per infringed copyright.
- This case highlights the growing legal scrutiny AI companies face over the use of copyrighted material in training data.
What happened
Sony Music Publishing and Warner Chappell have sued Anthropic, alleging the company illegally obtained and used tens of thousands of copyrighted songs, lyrics, and sheet music to train its Claude AI models. The lawsuit, filed in federal court in California, claims Anthropic used unauthorized copies of copyrighted musical compositions on a massive scale. The publishers allege that the material includes lyrics and sheet music associated with artists such as The Beatles, Taylor Swift, Michael Jackson, Mariah Carey, Bon Jovi, Leonard Cohen, and Katy Perry. The complaint also names Anthropic's CEO, Dario Amodei, and co-founder, Benjamin Mann, as defendants. According to the complaint, Anthropic allegedly obtained lyrics and sheet music through torrent downloads, scraping, and other methods. The publishers also claim that the company acquired material from lyrics websites and datasets, including Common Crawl. The lawsuit alleges that Claude can reproduce copyrighted lyrics verbatim in response to user prompts and that the copyrighted material was used to train the models to generate AI-produced song lyrics that could compete with existing copyrighted works as market substitutes. The publishers characterize the alleged conduct as "one of the largest and most blatant ongoing thefts of intellectual property in history."
Why it matters
This lawsuit adds another major copyright dispute to the growing list of legal challenges facing AI developers, raising broader questions about the technology industry's approach to acquiring training data. The case could distinguish itself from other copyright disputes involving Anthropic due to the scale of the alleged infringement, with claims involving "tens of thousands" of musical compositions. The lawsuit arrives as AI companies face legal challenges from various sectors, including authors, publishers, music companies, and news organizations, over the material used to train generative models. The publishers' claims also reflect the particular complexity of music copyright, which could make disputes involving music particularly consequential for AI developers attempting to establish legal frameworks for training models on copyrighted material. The potential financial exposure for Anthropic could reach billions of dollars, with the publishers seeking damages of up to $150,000 for each infringed copyright, as well as a court order preventing Anthropic from using their copyrighted works. The lawsuit alleges that Anthropic and its founders chose to obtain unauthorized copies rather than pay licensing fees for the use of copyrighted material in AI training and development. Anthropic has stated that it disagrees with the publishers' claims and intends to defend itself robustly in court.

Context
The lawsuit arrives as AI companies face legal challenges from various sectors, including authors, publishers, music companies, and news organizations, over the material used to train generative models. Anthropic has already faced similar litigation involving copyrighted content. Universal Music Group sued the company in 2023 over the alleged use of copyrighted song lyrics, and that case remains ongoing. The company also resolved a separate class action involving authors last year through a $1.5 billion settlement. The publishers referenced that agreement in their complaint, arguing that the settlement did not prevent further alleged infringement. The publishers' claims also reflect the particular complexity of music copyright, which could make disputes involving music particularly consequential for AI developers attempting to establish legal frameworks for training models on copyrighted material. The lawsuit highlights the growing legal scrutiny AI companies face over the use of copyrighted material in training data, with potential implications for the broader AI industry.
