LOS ANGELES — The legal battle over copyrighted material used to train artificial-intelligence systems is expanding after Sony Music and Warner Music filed a lawsuit against Anthropic in federal court in California.
The music companies allege Anthropic improperly used copyrighted lyrics and sheet music to train its Claude AI models. Anthropic has maintained that its AI training practices are protected by fair-use principles.
Hollywood and AI Collide
The dispute represents another major confrontation between the entertainment industry and artificial-intelligence developers.
AI companies need enormous amounts of information to train sophisticated models.
Publishers, musicians and other copyright holders argue that training AI systems on their work without permission can deprive creators of potential licensing revenue.
The music industry is particularly concerned because generative AI can produce text that resembles copyrighted lyrics.
Sony and Warner are seeking damages and court orders that could restrict how Anthropic uses copyrighted material.
The case could have implications far beyond the two companies.
If courts establish that AI developers must obtain licenses for certain training materials, the economics of developing large models could change significantly.
Technology companies could face much higher costs.
Artists and publishers could gain greater bargaining power.
The opposite outcome could strengthen the ability of AI companies to train models using publicly available material.
California has become one of the most important legal battlegrounds for this debate because many leading AI companies are based in the state.
The entertainment industry and Silicon Valley are therefore increasingly competing over the legal definition of data.
For Anthropic, the lawsuit creates another challenge as the company expands its AI business.
For creators, it represents a test of whether existing copyright law can keep pace with generative AI.
