Anthropic and its founders are the target of a major lawsuit filed by leading record labels and music publishers, which alleges the company unlawfully obtained and exploited protected works for AI training purposes.
AI copyright battle escalates as music publishers sue
In a complaint filed late Friday in the U.S. District Court for the Northern District of California, Sony Music Publishing, Warner Chappell, and several other music publishers have brought legal action against Anthropic, naming founders Dario Amodei and Benjamin Mann as co-defendants. The plaintiffs allege that Anthropic sourced copyrighted content through “torrenting, scraping, and downloading,” all in service of building its Claude AI system.
The publishers characterize these actions as a “brazen campaign” involving “illegally torrenting, scraping, and downloading copyrighted works,” and claim this conduct constitutes “blatant theft” affecting thousands of protected works. According to the suit, this represents one of the “largest and most blatant ongoing thefts of intellectual property in history.” For further information on the origin of the case, see Music Business Worldwide.
Anthropic denies wrongdoing; case follows earlier lawsuits
Responding through a formal email statement, an Anthropic spokesperson asserted, “We disagree with the publishers’ claims and we intend to defend ourselves robustly in court.” Anthropic insists its approach to copyright matters remains firmly within the bounds of current law.
Anthropic is no stranger to copyright litigation. Attorneys now handling the current case are also representing Concord Music Group and Universal Music Group in another lawsuit filed in January, as detailed in this report. These same legal professionals previously led the Bartz v. Anthropic case, in which authors alleged their books were used without approval in AI training datasets. That landmark suit concluded with Anthropic being ordered to pay $1.5 billion after the court ruled that while using copyrighted materials for AI might be legal, obtaining them through illicit means is not.
Claims of widespread copyright infringement highlight new case
Unlike previous litigation, this lawsuit targets the magnitude of Anthropic’s alleged copyright violations by charging the company with “flagrant piracy” via mass illegal torrenting. The music publishers accuse Anthropic of acquiring millions of copies of books, lyrics, and sheet music protected by copyright through these unlawful methods. Their argument seeks to establish that Anthropic’s practices represent systemic infringement on a grand scale, broadening the scope compared to previous actions.
The eventual resolution of this lawsuit could set significant legal standards for how copyrighted materials are used in AI training, with the outcome potentially shaping the legal framework for acquiring content in the development of new technologies, as publishers pursue major remedies and seek clarity about lawful boundaries.
