Reservoir v. Suno / Anthropic, twin AI training suits over 1,900 compositions
Whether Suno and Anthropic infringed independent publisher Reservoir's catalog by training AI models on 1,050 compositions (Suno) and the lyrics of 853 compositions (Anthropic) without a license; Reservoir seeks statutory damages of up to $150,000 per willfully infringed work plus DMCA damages, over $186 million against Suno and over $151 million against Anthropic.
Latest development
Filed October 21, 2026. Reservoir filed two separate suits in the Northern District of California: one against Suno over 1,050 compositions and one against Anthropic over 853. The complaints seek about $186 million and $151 million respectively, plus injunctions and impoundment of unauthorized copies. The Suno complaint alleges, based on a leaked codebase, that Suno scraped YouTube Music, Deezer and Genius; these are allegations, and no defendant has yet responded in court.

Background
On October 21, 2026, Reservoir Media Management and affiliates filed two separate copyright suits in the US District Court for the Northern District of California, one against AI music generator Suno and one against Anthropic. The Suno complaint covers 1,050 compositions for which Reservoir claims exclusive US control; the Anthropic complaint covers the lyrics of 853 compositions allegedly copied to train Claude.
The filings follow Round Hill's August suits against the same two companies and extend the wave of independent publishers litigating rather than licensing. Reservoir cites the Bartz v. Anthropic ruling in arguing that fair use does not excuse AI training on pirated or unlicensed works. These are allegations in complaints; neither defendant has answered.
Why It Matters for Artists and Fans
Independent catalogs are where songwriters without major-label leverage keep their rights. Each new suit that refuses a quiet licensing settlement raises the odds that a court, not a private deal, decides whether training AI on songs requires permission and payment.
