-Reddit filed suit against Anthropic alleging that since approximately 2022, Anthropic engaged in unauthorized scraping of Reddit's platform to obtain user-generated content for training its Claude AI models. Reddit contends that Anthropic's access violated Reddit's user agreement restrictions on data access methods and bypassed technical safeguards, constituting breach of contract, trespass to chattels, and violations of California's unfair competition law.<ref name="loeb"/><ref name="iipla">[https://iipla.org/anthropic-reddit-spar-over-keeping-ai-case-in-federal-court/ IIPLA, Anthropic, Reddit Spar Over Keeping AI Case in Federal Court]</ref>

-Anthropic removed the case to federal court, arguing that Reddit's claims were preempted by the federal Copyright Act under 17 U.S.C. § 301. On March 31, 2026, the federal court granted Reddit's motion to remand, holding that the Copyright Act does not preempt Reddit's state-law claims. The court found that each of Reddit's claims contains "extra elements" qualitatively different from copyright's exclusive rights, including:

-* Breach of user agreement restrictions on access methods
-* Bypassing technical safeguards and infrastructure protection measures
-* Privacy protections and consumer fairness beyond mere reproduction
-The court applied the two-part preemption test under § 301: (1) subject matter within copyright (satisfied, as Reddit's content is original expression), and (2) equivalent rights (not satisfied due to the extra elements). The case was remanded to California state court.<ref name="loeb"/><ref name="law360"/>
-== Significance ==
-The remand ruling is significant because it means AI training data cases involving state-law claims (breach of contract, trespass to chattels, unfair competition) may proceed in state court, even where the underlying content is copyrightable. This avoids federal court's exclusive jurisdiction and allows plaintiffs to pursue broader remedies under state law. The ruling also signals that AI companies cannot automatically federalize scraping disputes by raising copyright preemption defenses.
-Anthropic may appeal the remand order. In state court, Anthropic may still raise fair use and other defenses.<ref name="loeb"/>
