What happened in UMG v. Udio? (plain-language case tracker)

Timeline from the docket (1:24-cv-04777, S.D.N.Y.)

• June 24, 2024 — the same label coalition sues Uncharted Labs (Udio's legal entity) in the Southern District of New York.
• November 5, 2025 — a stipulation so-ordered by Judge Hellerstein states that all claims "asserted by Plaintiffs UMG Recordings, Inc. and Capitol Records, LLC … are hereby dismissed without prejudice," and that claims "asserted by all other Plaintiffs … shall not be affected." Without prejudice means the claims can be refiled — the standard posture while a commercial relationship is being implemented.
• November 25, 2025 — Warner's entities dismiss, also without prejudice.
• April 15, 2026 — the court denies the defense motion to dismiss one of the remaining Sony plaintiffs' counts: the case proceeds.
• June 29, 2026 — scheduling order extends document discovery to August 25, 2026 and sets a status conference for September 18, 2026.

How does this differ from the Suno case?

Same plaintiffs' coalition, same filing day, different exits: Warner left the Suno case with prejudice but this one without; UMG left this case but is still fighting Suno. The asymmetry is the tell that these exits are negotiated commercial positions, not legal conclusions — and why per-case, per-plaintiff tracking (which this Index does) beats headline summaries.
