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.

Court orderOctober 8, 2025Concord Music Group, Inc. v. Anthropic PBC (Concord I) · N.D. Cal. 5:24-cv-03811

Judge denies music publishers' request to add BitTorrent claims to their first suit against Anthropic

The publishers had asked on Aug. 11, 2025 to file a second amended complaint. Their motion said they learned from Judge Alsup's rulings in Bartz v. Anthropic that Anthropic had used BitTorrent to download books from LibGen and Pirate Library Mirror, and alleged that those books included lyric and sheet music collections containing their songs. They wanted to add those downloads to their existing claims and to add new distribution claims based on alleged uploading during the torrenting. After a hearing, Judge Lee denied the motion in a minute order, for reasons stated on the record; the written order does not set them out. The publishers later brought the torrenting claims in a separate suit filed Jan. 28, 2026.

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.
