How the e-mails work

Uses the search, kind and company you set above (not the month or sort). As we post means within about 15 minutes of a new item; digests go out in the morning, U.S. Central time, weekly on Mondays, and only when something new matches. Updates start right away, and every e-mail has a one-click unsubscribe. If you tick Catch me up, the earlier items that match also come two a day, oldest first, each morning until you are up to date; you can stop that alone from any e-mail. Someone you invite gets one e-mail asking them to accept, and nothing more unless they do; we don’t tell them who invited them. Privacy.

AllegationAugust 28, 2026Sony Music Publishing (US) LLC v. Anthropic PBC · N.D. Cal. 5:26-cv-09217

Music publishers sue Anthropic and two founders, alleging the books it torrented from LibGen and PiLiMi included their lyrics and sheet music

Sony Music Publishing, Warner Chappell and affiliated publishers sued Anthropic, Dario Amodei and Benjamin Mann. Relying on the findings in Bartz v. Anthropic, the complaint alleges that the millions of books Anthropic downloaded by BitTorrent from LibGen in June 2021 and from the Pirate Library Mirror in July 2022 included books containing lyrics and sheet music to the publishers' songs, and that because BitTorrent uploads while it downloads, the publishers' distribution right was infringed as well as their reproduction right. It also alleges copying from Books3, The Pile and Common Crawl, and seeks to hold the two founders personally liable. These are allegations; no court has ruled on them in this case.

What the labels mean

Every item says what kind of source it rests on. A court ruling or order is the court's own statement. A company filing is what a defendant says about itself. A government filing is a statement by a government agency that is not a party to the case, such as a statement of interest; it is the government's position, not a ruling. An allegation is what a complaint or motion claims and has not been decided. Reported means press reporting we have not confirmed from the primary document. Summaries are our own; follow the links for the source.

This page is general information, not legal advice. An allegation is not a finding. Whether any of this matters for a particular work or claim is a question for a lawyer.
