Background of the Lawsuit

Plaintiffs allege that Anthropic PBC engaged in copyright infringement by downloading and using pirated copies of books from ‘shadow library’ websites, specifically Library Genesis (LibGen) and Pirate Library Mirror (PiLiMi), to train its Claude artificial intelligence models without the authors’ permission or compensation. The lawsuit claims Anthropic created a ‘central library’ of these infringing works for AI training purposes.
