A class-action lawsuit against Anthropic regarding alleged piracy has been rejected, with the court finding insufficient grounds for the claims made by the plaintiffs. The decision has significant implications for the legal landscape surrounding AI technologies and copyright issues.

Industry groups, along with Anthropic, warn that certifying copyright class actions in AI training cases could deter investment in AI due to potential excessive liabilities and unresolved copyright issues. Critics argue that the complexity of proving authorship in such cases makes class actions unsuitable, while a judge's lack of thorough analysis of copyright ownership raises further concerns.
