What are the Reservoir lawsuits against Suno and Anthropic?
On October 21, 2026, music publisher Reservoir filed 2 copyright complaints in the US District Court for the Northern District of California. One names Suno over 1,050 compositions. The other names Anthropic, the company behind Claude, over the lyrics of 853.
The songs include Joni Mitchell’s “Both Sides Now”, Johnny Cash’s “Ring of Fire” and Madonna’s “Papa Don’t Preach”. I covered the filings and Reservoir’s song list 2 days after they landed.
Who is involved in the Reservoir lawsuits?
Reservoir sues through 3 entities: Reservoir Media Management, Inc., its UK subsidiary, and Shapiro, Bernstein & Co. Limited. Its lawyer is Richard S. Busch of Adams & Reese, who also represents Round Hill Music and Gerencia 360 against Suno.
Suno is the AI music generator already facing the major labels and a German ruling in GEMA’s favor. Anthropic is sued separately over lyrics and already faces several publisher suits in the same court.
What Reservoir claims Suno did
Reservoir says Suno ripped its songs from YouTube with YT-DLP, through proxy networks from Bright Data, and that the scraper dropped the headers and footers where songwriter credits sit. It cites leaked Suno source code that it says names “Both Sides Now”, Ben Harper’s “Diamonds on the Inside” and “Ring of Fire”.
It also claims Suno trained on covers paired with the original recordings, and that a “Miles Davis like” blues prompt returned 2 tracks that are unlicensed derivatives.
What Reservoir claims Anthropic did
Reservoir says Claude learned its lyrics from Common Crawl, Books3 and The Pile, and that Anthropic picked a text-extraction tool called Newspaper because it removed copyright notices. It quotes Claude Sonnet 5 describing its own song rewrites as landing “very close to the originals”.
What is Reservoir asking the court to do?
Each complaint asks for actual damages and profits, or statutory damages of up to $150,000 per song for willful infringement, $2,500 per circumvention and $25,000 per removal of copyright management information. That works out to $177,500 per song, or $186.4 million against Suno and $151.4 million against Anthropic.
Both also ask for impoundment or destruction of every unauthorized copy, including copies in training datasets, internal repositories, model weights and server infrastructure, plus a full accounting of the training data.
How does this case fit the wider AI music litigation?
Reservoir is the third Busch client to sue Suno since August, after Round Hill and Gerencia 360. On the Anthropic side, it joins Concord v. Anthropic, where Judge Eumi Lee heard the fair use motions on the day Reservoir filed, and Sony Music Publishing and Warner Chappell v. Anthropic.
What this means for you
- The song list sets the price. Reservoir’s exhibit lists registered songs with a statutory maximum on each, so the demand grows with every song added.
- The DMCA counts don’t depend on fair use. Circumvention and stripped credits ask how the files were taken, not what the model produced.
- Nothing changes for existing Suno tracks today. The complaints target Suno’s and Anthropic’s copies and models, not user accounts, and no court has ruled.
How this fits the bigger picture
Publishers are no longer waiting on the major-label cases. Each new filing brings its own catalog list and the same per-song arithmetic. The next thing to watch is how Suno and Anthropic answer.
