Reservoir has added 608 works to its copyright lawsuits against Suno and Anthropic. The expanded cases also put Suno’s own words under scrutiny: Reservoir says the company’s music generator reproduces melodies that Suno has told another court it does not reproduce.
The Reservoir copyright lawsuits now list 2,511 compositions across the two complaints, up from 1,903. The music publisher filed amended complaints Nov. 11, following its original lawsuits Oct. 21 in federal court in Northern California.
The Suno complaint lists 1,368 works, up from 1,050. The Anthropic complaint lists 1,143, up from 853. Reservoir says it owns or exclusively controls the U.S. copyrights in the listed works.
Reservoir Points to Suno’s Own Words
The amended Suno complaint adds two exhibits containing 34 recorded outputs that Reservoir alleges infringe its copyrights. One example, tied to Evanescence’s “Bring Me to Life,” allegedly reproduces part of the song’s vocal melody.
Reservoir contrasts that example with Suno’s position in a separate lawsuit brought by Jason Isbell and three other musicians. In a Nov. 3 memorandum supporting its request to dismiss that proposed right-of-publicity class action, Suno said its outputs “do not reprise specific melodies from songs someone else wrote.”
Reservoir argues that its example contradicts that statement. Whether the output infringes the song’s copyright remains a question for the court.
The publisher also alleges that Suno removed a lyric search feature less than a year after introducing it. Reservoir says the removal made infringing outputs harder for rights holders to find. The complaint presents that allegation on information and belief.
What the Reservoir Copyright Lawsuits Seek
Reservoir seeks actual damages and the companies’ profits or, alternatively, statutory damages of up to $150,000 per work willfully infringed.
Adding the amounts requested across the copyright claim and two Digital Millennium Copyright Act counts brings the figures to about $242.8 million against Suno and $202.9 million against Anthropic. Together, that is about $445.7 million, up from roughly $337.8 million in the original complaints.
Those figures describe what Reservoir is seeking. No court has awarded those amounts.
The Anthropic Case Centers on Lyrics
The amended Anthropic complaint largely retains the original allegations while adding works and revising the damages requests. Reservoir alleges that Claude Haiku 4.5 and Sonnet 5 refuse requests to reproduce copyrighted lyrics but will create unauthorized derivative versions.
An Anthropic spokesperson told Billboard in October: “We disagree with the allegations and intend to defend this case vigorously.”
The cases concern the rights in musical compositions. Suno also faces a separate lawsuit involving Elvis Presley’s voice, adding another legal dispute over what AI music services can reproduce without permission.
