According to CoinMeta, reported by Cailian News on October 23rd, Reservoir music management company has accused Anthropic PBC of unauthorized reproduction of copyrighted lyrics for training its Claude artificial intelligence model, without paying any copyright fees throughout the process. The music publisher claims that the infringement continues, and the output generated by Claude almost completely replicates the relevant songs, including copyrighted works held by Reservoir. In its lawsuit, Reservoir requests the court to order statutory damages, a permanent ban, and other related remedies, stating that Anthropic's actions have severely damaged the commercial value of its copyright licensing business and violated the Digital Millennium Copyright Act (DMCA).
