Reservoir expands copyright lawsuits against Suno and Anthropic to more than 2,500 songs combined

Reservoir has expanded its copyright lawsuits against AI music company Suno and AI developer Anthropic, adding more than 600 songs and bringing the total number of compositions named to 2,511. The claims allege unauthorised use of Reservoir-controlled works; the amended filings also raise the damages sought, though the allegations have not been established in court.

The Suno complaint now covers 1,368 works and the Anthropic case 1,143, compared with 1,050 and 853 respectively at filing. Reservoir puts its combined claims across copyright and two Digital Millennium Copyright Act counts at more than $445.7 million, up from nearly $337.8 million. The amended Suno filing includes 34 alleged infringing output examples and points to one it says reprises a vocal melody from Evanescence’s “Bring Me to Life”; Suno has previously said its outputs do not reprise specific melodies.
