Reservoir Sued Suno and Anthropic for Up to $338 Million. Here’s What Is Actually on the Record.
Another week, another AI music lawsuit, and this one has a number attached that will travel fast. Before it does, here is what the filings say, what they do not prove, and what a working creator should take from it.
What Was Filed
On October 21, music publisher Reservoir filed two separate suits in the U.S. District Court for the Northern District of California. Per Law Commentary (October 24), which cites the complaints, one targets Suno over 1,050 compositions and the other targets Anthropic over lyrics from 853 compositions. Music Business Worldwide’s October 23 round-up, Billboard and CelebrityAccess (October 25) all report the filings. MBW says the Suno catalog reportedly includes songs by Joni Mitchell, Johnny Cash and Madonna.
Reservoir seeks roughly $186.4 million from Suno and $151.4 million from Anthropic, about $338 million combined. Those are maximum statutory figures. They assume Reservoir wins on liability and persuades the court to award the top of the range.
What Reservoir Alleges
Against Suno, the complaint alleges the company copied protected works from online sources, including YouTube Music, to train a commercial song generator, and that it began licensing only after legal pressure, which Reservoir offers as evidence that a licensing market exists. Both suits add Digital Millennium Copyright Act claims over circumventing access controls and stripping copyright management information such as songwriter credits. Reservoir attorney Richard Busch accused Suno of copying first and licensing later.
What Is Not Established
These are allegations. No court has ruled. Anthropic disputes the claims and says it will defend the case. I found no public Suno response specific to this complaint as of this writing. Suno’s position in the separate Universal and Sony case is on the record, though: in its September 1 answer, reported by MBW on September 8, it admitted obtaining YouTube audio for training while asserting fair use and arguing that any infringement was innocent. In that same case Suno acknowledged on October 20, per Law Commentary, that it kept some training recordings, saying this matched the labels’ earlier requests to preserve datasets.
The Other Side of the Table
The industry is not uniformly suing. Suno’s v6 models launched September 9 with Warner Music Group, BMG and Believe as partners, per MBW. Universal and Sony are not in that deal and remain plaintiffs. Whether training on copyrighted music is fair use is still undecided, and that question, not the headline dollar figure, is what these cases are really about.
What This Means for You
The rules are still being written, so keep your own paper trail. Save your prompts, stems, project files and the date and plan tier you generated on. If a platform’s terms or a court changes the picture, you want proof of what you made and how.
Check the license behind the tool. Suno’s paid terms assign output rights to subscribers, but Suno makes no guarantee that copyright will vest in any output. Know what your platform actually promises you in writing.
Put more of yourself in the record. Lyrics, performance, arrangement and mixing by hand strengthen both your claim to the work and your identity as an artist.
AI is permanent, and the legal system is catching up to it in public. Lawsuits like this one are how the licensing market gets priced, and they lower the gate more safely for creators when the rules are settled. Stay informed, stay documented, and keep making music.
