A federal judge in San Francisco ruled that Anthropic's use of copyrighted books to train its AI system is fair use under US copyright law.
Judge William Alsup found Anthropic's AI training transformative as it analyzed writing, extracted uncopyrightable data, and developed new technology.
Training the large language model (LLM) was considered transformative as it aimed to teach statistical relationships between words to generate new text.
The process was compared to learning how to write by reading books rather than copying them verbatim.
There was no evidence that Anthropic's model reproduced or directly substituted the original works.
Anthropic downloaded millions of copyrighted books from various sources, including pirate sites, to train its AI model.
The court ruled that obtaining books through piracy infringed authors' copyrights and was not protected as fair use.
A trial is scheduled in December to determine damages related to the infringement.
The case originated from a class action lawsuit by authors alleging Anthropic used unauthorized copies of their books for training its AI model.
While training AI on lawfully obtained works is legal, relying on pirated materials was criticized for undermining copyright protections.
The ruling is considered significant for the AI industry, affirming fair use with legally obtained materials but cautioning against piracy.
Various companies, including OpenAI, Meta, and Stability AI, are facing legal challenges over alleged unauthorized use of copyrighted material for training AI models.
The decision is anticipated to impact copyright disputes in the AI industry, with appeals and further litigation likely to follow.
