A federal judge in San Francisco has dismissed a copyright lawsuit filed by authors Michael Chabon, David Henry Hwang, and others against AI company Anthropic. The authors claimed Anthropic violated their rights by using their works to train its AI models without permission. Judge Vince Chhabria ruled that the authors failed to show specific evidence that Anthropic had actually used their copyrighted works in training its Claude AI model. The judge noted that the authors’ complaint relied heavily on Claude’s ability to discuss their books rather than proving the works were used in training. The ruling gives the authors 30 days to revise their lawsuit with more specific evidence. This case is part of a broader legal battle over AI companies’ use of copyrighted materials for training, with similar lawsuits pending against other major AI firms like OpenAI and Meta. The judge’s decision highlights the challenge authors face in proving their works were specifically used in AI training datasets. However, the ruling was procedural and didn’t address the fundamental question of whether using copyrighted materials to train AI is legal. The case reflects growing tensions between content creators and AI companies over intellectual property rights and fair use in the age of artificial intelligence.
