AI Lawsuit Tracker counts 248 cases against 76 companies; copyright dominates

Oct 11, 2026 · Gathered automatically from public sources. Not reviewed by a person.

What happened

An updated public database surfaced on October 11, 2026 now tracks 248 AI-related lawsuits against 76 companies across 14 jurisdictions, updated through October 8. Copyright dominates with 145 cases — well over half the total — and 69 cases are flagged as class actions; other categories include chatbot harm, privacy and biometrics, deepfakes and likeness, and antitrust. The most-sued companies are OpenAI (55 cases), Google (25), Meta (21), Microsoft (21) and Anthropic (18); 134 cases are active while only 25 are decided and 18 settled. The overview highlights the US Third Circuit's September 29 affirmance in Thomson Reuters v. Ross — described as the first federal appellate decision on fair use in AI training — while noting it involved a non-generative system and does not decide the pending generative-AI cases.

Why it may matter to you

It is a single, current index of the whole AI-copyright litigation landscape: who is being sued most, where cases stand, and how few have reached final decisions. The Third Circuit's Ross affirmance is the closest thing to appellate guidance on AI-training fair use, even though its limits mean generative-AI cases remain undecided.

What is not yet known

The authors caution that the tracker is anonymous and unaudited and should be used as an index to dockets rather than a legal source. Individual case counts and statuses should be verified against court records.
