Which AI companies have been sued?
Every AI defendant we track, ranked by live case count. Click any company to see every case naming them — court, docket, status, and what's next.
The list below is alive. Counts update from the case dataset on every page load. If a new case is filed naming any of these companies, it appears in their tracker page within 24 hours of docket entry.
The full directory
Each card shows live tracked cases for that defendant. The number includes copyright, DMCA §1202, BIPA biometric, defamation-by-hallucination, and right-of-publicity actions. It excludes securities-fraud "AI-washing" complaints and ordinary employment matters where AI is incidental.
Reading the leaderboard
The headline counts hide important structural differences. A few things to keep in mind as you scan:
- OpenAI's lead can include co-defendant volume. Some lawsuits name OpenAI and Microsoft as joint defendants because of the Microsoft–OpenAI commercial relationship and Azure-hosted training. The directory above counts each case once against the first matching defendant.
- Anthropic's count is Bartz-driven. Several of Anthropic's filings consolidate around the Bartz docket. After the $1.5B settlement, the remaining cases focus on legally-acquired data and post-settlement plaintiffs.
- Music defendants cluster. Suno and Udio were sued in parallel by RIAA labels. The two cases have nearly identical fact patterns and identical fair-use briefing, which is why they tend to track together.
- Image-generation defendants split. Stability AI faces both U.S. (Andersen) and U.K. (Getty) actions. Midjourney's headline case — Disney v. Midjourney — is the first studio-led suit against a generative-image company.
- Character.AI is the outlier. Its tracked cases are not copyright cases. They are wrongful-death and product-liability claims tied to teen users, which makes Character.AI's litigation profile structurally unlike the others.
Tracked but not yet in the verified dataset
A few defendants we monitor but where no case has yet entered the verified dataset (cards above will show "No verified case yet"):
- xAI — Despite the company's scraping of X for Grok training, no IP suit naming xAI has yet entered our verified dataset. This is one of the most-asked questions we get.
- Mistral — Open-weights distribution and France-based incorporation have so far insulated Mistral from U.S. plaintiff actions making it into the dataset.
- Udio — The active U.S. docket against Udio is smaller than Suno's; check the card above for the current verified count.
How we count
Each defendant's count includes only cases where the company is a named party. Subsidiaries are folded into the parent — Marvel-and-Lucasfilm-as-plaintiffs roll up to Disney; Microsoft-and-LinkedIn-as-defendants roll up to Microsoft. We exclude stayed and pre-removal state filings unless they re-emerge under a federal docket. Full methodology here.
