US judge certifies 'pirated books' class of copyright owners suing Anthropic
( July 17, 2025, 17:24 GMT | Official Statement) -- MLex summary: US District Judge William Alsup partially granted a motion for class certification in copyright litigation against Anthropic. A "pirated books" class will include all "beneficial or legal copyright owners" of books in versions of Library Genesis and Pirate Library Mirror that Anthropic downloaded, regardless of whether they were used for AI training. He denied certification of an alternative Books3 class, saying books downloaded from that source "came with fewer fields of metadata, less routinely complete files of content, and as a result the identification of titles and authors would be too problematic."See file attached....
