Suno cites Udio ruling in bid to block Sony and Universal's 61,026-track expansion
Suno asked the Boston federal court to reject Sony and Universal’s motion to add 61,026 recordings to their copyright case against it. The company filed a notice of supplemental authority days after Judge Alvin K. Hellerstein blocked Sony’s near-identical expansion attempt against Udio on July 2, 2026.
Why the Udio ruling gives Suno a template
Hellerstein kept the New York case against Udio at its original 333 works, writing there is “no requirement” the labels’ wider infringement claims “be done in this lawsuit.” Suno’s filing quotes the order’s core finding: adding 30,000 works near the close of discovery would “materially alter the scope of the case.”
For the same reasons that the Udio court denied the motion in that case, as well as the additional bases identified in Suno's briefing, this Court should deny Plaintiffs' motion here as well.
What is at stake if the Suno case stays at 560 works
The labels’ proposed expansion would push potential statutory damages past $9 billion at up to $150,000 per work. Blocked, Suno’s exposure stays anchored to the 560 works Sony and Universal named in June 2024, as Digital Music News reported.
Suno also pressed the timing argument: “After two years of extensive fact discovery, Suno is entitled to a timely consideration of its fair use defense.” The full case history sits in the RIAA v. Suno tracker.
Frequently asked questions
What did Suno's supplemental authority filing ask the Boston court to do?
Suno asked the Massachusetts federal court to consider Judge Hellerstein's July 2, 2026 order in the Udio case, which denied Sony's motion to add 30,442 recordings, when ruling on Sony and Universal's near-identical motion to add 61,026 works to the Suno case. Suno wants the motion denied.
How does the Udio expansion ruling affect Sony and Universal's case against Suno?
It is persuasive, not binding. The Udio order came from a different district, so the Boston judge can ignore it. But it gives Suno a fresh federal ruling holding a late, massive expansion would materially alter a case near the close of discovery, the exact scenario in the Suno lawsuit.
Has the court ruled on Sony and Universal's motion to add 61,026 recordings to the Suno case?
No. As of July 6, 2026, the motion is still pending in the District of Massachusetts. Suno's supplemental authority notice is an argument against it, and the court has not yet decided whether the case grows from the original 560 works.
