Suno Faces Bigger Reservoir Lawsuit As AI Claims Top $445 Million

Suno’s fight with Reservoir now covers hundreds more songs, pushing the publisher’s combined demands against the AI music company and Anthropic above $445 million. The catalog at issue includes music recorded by Madonna, Joni Mitchell and Miles Davis.

Reservoir filed amended complaints in Northern California federal court on November 11. Its revised Suno complaint identifies 1,368 compositions, while the separate Anthropic action covers 1,143 works.

Those totals increase the lists from 1,050 and 853 songs, respectively. Reservoir is asking for as much as $205.2 million in copyright damages from Suno and $171.45 million from Anthropic, before its additional claims over access controls and copyright information.

Adding the amounts requested across all three claims in both lawsuits brings the total to $445,702,500. That is Reservoir’s demand, not money a judge has awarded.

The extra demands total $37.62 million against Suno and $31.43 million against Anthropic. They concern allegations that the companies bypassed protections on source material and removed copyright-management information, including details identifying songwriters and publishers.

The Suno filing keeps a detail familiar to anyone who listens to rap: producer tags. Reservoir alleges that generated tracks reproduce those recognizable signatures, part of the producer-tag dispute AllHipHop previously covered.

“For example, Suno has output ‘producer tags’ which are an integral musical part of songs throughout the hip-hop and rap genres, and function as a type of signature for a producer,” Reservoir alleges in the amended complaint.

The publisher also points to 34 recorded examples it says demonstrate copied musical material. Its claims go beyond what listeners hear: Reservoir accuses Suno of obtaining protected music without permission and stripping information that identifies its creators and owners.

Anthropic faces a different output complaint centered on Claude. Reservoir alleges that the chatbot reproduces lyrics and makes adaptations using its compositions, and claims it copied material during training and retains it for future use.

Both filings seek orders to stop the alleged infringement and require unauthorized copies to be impounded or destroyed. Reservoir also wants an accounting of the companies’ training data and scraping activities involving its music.

Reservoir Media Management, its UK affiliate and Shapiro, Bernstein & Co. Limited are the plaintiffs in both cases.
