Reservoir Seeks More Than $445 Million in Expanded Lawsuits Against Anthropic and Suno
Key Facts
Reservoir is seeking more than $445 million in statutory damages in amended complaints against Anthropic and Suno, according to a report published by Digital Music News on November 12, 2026. The claims include $171.5 million in the Anthropic case and a maximum of $205.2 million in the Suno case. These are amounts Reservoir is seeking under the complaints, not damages awarded by a court. The company says the number of works it alleges infringed its rights increased in both amended filings. The escalation comes as Suno faces multiple legal disputes over the use of music in artificial intelligence systems.
In the amended complaint against Anthropic, Reservoir identified 1,143 works it alleges were infringed, compared with 853 works in the earlier complaint. The company is seeking $171.5 million in statutory damages for those works. The report links the allegation to Claude’s outputs, saying the complaint alleges “verbatim or near-verbatim reproduction of song lyrics.” The claims focus on song lyrics and outputs attributed to Claude. The report did not say that a court had issued a ruling resolving these allegations or awarding the requested damages.
In the Suno case, the number of works Reservoir listed in its amended complaint rose to 1,368, from 1,050 in the earlier complaint. The company is seeking the maximum statutory damages of $205.2 million for the works at issue. The list of rights holders named includes Dionne, Joni Mitchell, Joe Walsh, Miles Davis, Sonny Rollins and Travis Tritt, among others. Reservoir says its claims include alleged infringement related to model training, alleged violations of the Digital Millennium Copyright Act, and rights-infringing outputs. The report also cites an allegation that Suno created derivative works; all are claims in the lawsuit that have not been resolved by a court.
The comparison shows increases in both filings: from 853 to 1,143 works in the Anthropic case, and from 1,050 to 1,368 in the Suno case. Reservoir linked the expanded lists of works to the increased damages it is seeking, but the report does not cite a ruling or court outcome on those claims. The report describes the Suno filing as part of “at least a dozen heated legal battles” facing the company. Among the entities it says have sued Suno are Universal Music and Sony Music, along with GEMA, SOCAN, KODA and Round Hill. The context places the amended complaint within a series of disputes over music rights and their use in generative systems.
EL7 previously reported on October 23, 2026, that Reservoir had filed two lawsuits against Suno and Anthropic, noting 1,050 works in the Suno case and 853 works in the Anthropic case at the time. Those figures were from the earlier complaints, before the lists increased in the amendments covered by the November 12 report. More broadly, the Associated Press reported that Universal Music, Sony Music and Warner Records sued Suno and Udio in 2024, accusing the companies of exploiting protected recordings without compensating their owners. The news agency said Suno had settled its dispute with Warner, while Sony had not settled with either company at the time of publication, and that Suno faced legal challenges in Europe. In the context of those cases, Reuters said Suno and Udio defended their use of protected recordings to train their systems as fair use under U.S. law, and described the lawsuits as an attempt to stifle independent competition.
