In a lawsuit filed by Reddit against Anthropic, a federal district court has remanded the case back to California state court, ruling that Reddit's state-law claims for breach of contract, unjust enrichment, trespass to chattels, tortious interference, and unfair competition are not preempted by the federal Copyright Act. The court found that Reddit's allegations, including that Anthropic bypassed technical safeguards to access and use Reddit user content to train its AI chatbot, contained 'extra elements' beyond copyright infringement that allowed the state-law claims to proceed.

Why it matters

This ruling is a significant win for Reddit in its ongoing battle against alleged unauthorized scraping and use of its platform content by AI companies. The decision affirms that social media platforms can pursue state-law claims to protect their user data and technical infrastructure, even if the content itself may be subject to copyright protection. The case highlights the tensions between AI development and user privacy/platform integrity that many tech companies are navigating.

The details

Reddit filed suit against Anthropic in California state court, alleging the AI company scraped user content from Reddit's platform without authorization and used it to train its AI chatbot Claude. Reddit asserted five state-law causes of action, including breach of contract, unjust enrichment, trespass to chattels, tortious interference, and unfair competition. Anthropic removed the case to federal court, arguing the Copyright Act preempted Reddit's state-law claims. However, the district court sided with Reddit, finding the state-law claims contained 'extra elements' beyond copyright infringement, such as allegations that Anthropic bypassed Reddit's technical safeguards and violated its user agreement. The court ruled the Copyright Act did not preempt Reddit's claims, and remanded the case back to state court.

  • Reddit filed the lawsuit against Anthropic in California state court in early 2026.
  • The federal district court issued its ruling remanding the case to state court on April 16, 2026.
