The ruling provides a significant, albeit partial, win for AI companies like Anthropic, OpenAI, Microsoft, and Meta Platforms, by affirming that training AI models on copyrighted material can be considered fair use, potentially reducing future licensing costs for AI development. However, the decision also establishes a precedent that the unlawful storage of pirated content, even if not directly used for training, constitutes copyright infringement, which could lead to substantial damages for Anthropic and similar firms.
A US federal judge, William Alsup, issued a mixed ruling in a copyright lawsuit against AI company Anthropic. The judge ruled that Anthropic's use of copyrighted books by authors Andrea Bartz, Charles Graeber, and Kirk W. Johnson to train its Claude large language model was legal under the 'fair use' doctrine, a significant victory for the AI industry. However, William Alsup also found that Anthropic's practice of copying and storing over 7 million pirated books in a 'central library' constituted copyright infringement. This part of the ruling means Anthropic will face a trial in December to determine statutory damages, which could be up to $150,000 per work for willful infringement. The decision is seen as a landmark ruling for the burgeoning AI industry, providing clarity on the legal limits and opportunities for AI companies like OpenAI, Microsoft, and Meta Platforms, which are also facing similar lawsuits.
