The Bookseller - News - Anthropic sued by trio of US authors over use of 'pirated books' to train AI chatbot Claude

Earlier this week, lawyers acting on behalf of authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson filed a copyright infringement case in California, US, claiming Anthropic had used "pirated" copies of their books to teach its AI chatbot, Claude.

The legal action accuses Anthropic of "downloading and copying hundreds of thousands of copyrighted books taken from pirated and illegal websites".

This is the latest in a series of legal cases where AI firms stand accused of using authors' material to teach large language models (LLMs) without their consent, or by using allegedly stolen copies of their books.
