forty-eight pages
Sony and Warner sued Anthropic and named two founders personally. The personal names are the new part, and the reason they are there is a ruling Anthropic already lost.
Filed late on Friday 29 August in the Northern District of California. Sony Music Publishing, Warner Chappell, and other publishers against Anthropic — and against Dario Amodei and Benjamin Mann, as individuals.
Forty-eight pages. The language in them is not the careful register of a complaint that expects to negotiate: a “brazen campaign of illegally torrenting, scraping, and downloading copyrighted works,” “blatant theft,” “flagrant piracy,” and — the line that made every headline — “one of the largest and most blatant ongoing thefts of intellectual property in history.”
Thousands of copyrighted compositions. Millions of book copies obtained by torrent, the publishers say, including material carrying lyrics and sheet music. Reporting on the complaint identifies Library Genesis and the Pirate Library Mirror among the alleged sources. Statutory damages sought at up to $150,000 per infringed work, jury trial demanded.
Anthropic’s response, in full: “We disagree with the publishers’ claims and we intend to defend ourselves robustly in court.”
To read the filing correctly you need the case that came before it. In Bartz, the authors’ suit, a judge drew a line straight through the middle of the AI copyright question: training a model on copyrighted works can be lawful, and obtaining those works by piracy is not. Two separate acts. Anthropic won the first half and paid $1.5 billion on the second.
That outcome did not resolve the AI copyright fight. It split it in two and handed plaintiffs the easier half.
Because the hard half — is training a transformative fair use? — requires a court to reason about a technology it has no settled doctrine for, and reasonable judges will disagree for a decade. The easy half is a question the law has answered ten thousand times since Napster. Did you download a file you had no license to download? That case does not need an expert on attention mechanisms. It needs a server log.
So look at what this complaint leads with. Not “your model reproduces our lyrics.” Torrenting. Scraping. Named piracy sites. The publishers are not litigating the frontier. They are running the play that already worked, on a defendant who already lost it, in front of a court that has already written the rule down.
The individual defendants are the escalation, and they are worth being precise about.
Naming a chief executive and a co-founder personally in a copyright case is a claim of contributory or vicarious liability — the argument that these people knew about the conduct, had the ability to stop it, and had a direct financial interest in it continuing. It is not routine. It is a specific allegation that the decision to acquire the corpus that way was made by people with names, at a level where those names are known.
What it does tactically is change who in the room is exposed. A corporate defendant weighs a judgment against a balance sheet, and Anthropic’s balance sheet is now very large. An individual defendant weighs it against everything they own. Those two people evaluate settlement differently from each other and differently from the company, and the plaintiffs know it. That asymmetry is the point of putting the names in.
Whether it survives a motion to dismiss is a separate question, and personal-liability theories against executives get trimmed more often than they stick. It may not need to survive long to do its work.
The multiplier is where this stops being a normal lawsuit. $150,000 per work, statutory, times “thousands” of compositions. Do the arithmetic at the low end of thousands and the number clears half a billion before you have argued about a single song. Do it at the high end and it clears the $1.5 billion Anthropic just paid.
Statutory damages are the mechanism, and they were written for a world where infringement was countable — this many copies, of this many records. Applied to a training corpus, the count is whatever the plaintiff can enumerate, and a music publisher’s catalog is enumerable to the individual composition. That is not an accident of this case. It is the structural reason the music industry, not the film industry or the news industry, keeps being first through the door.
They have the best-indexed rights on earth, and the count is the claim.
