Oura Sues Ultrahuman Again Over the Ring Pro, Seeking a US Sales Ban

Oura has filed a new patent infringement suit against Bengaluru-based Ultrahuman in the US District Court for the Eastern District of Texas, aimed at the Ultrahuman Ring Pro. The suit was filed on October 22, 2026, and asks for damages and a permanent injunction that would stop US sales of the ring (TechCrunch via Yahoo Finance). The allegations are unproven, and no court has made any ruling.

What the suit claims

The complaint relies on two patents. One is design patent D804,471. The other is utility patent 12,769,363, which covers a curved battery, circuit board, magnets and sensors inside a ring. That utility patent was issued on October 20, two days before the suit was filed (Free Press Journal).

SVTronics, an electronics manufacturer in Plano, Texas, is also named as a defendant. Oura alleges that it makes the Ring Pro there under Ultrahuman's direction and control (the5krunner). Coverage so far is based on press reports of the complaint rather than a published court ruling.

How the two companies got here

Date	Oura vs Ultrahuman timeline
Aug 2025	US International Trade Commission rules for Oura over the Ultrahuman Ring Air
Oct 2025	Import ban on the Ring Air takes effect
27 Feb 2026	Ultrahuman unveils the redesigned Ring Pro at $479
Mar 2026	US Customs and Border Protection clears the Ring Pro, allowing its US return
20 Oct 2026	Oura is granted utility patent 12,769,363
22 Oct 2026	Oura files the new suit in Texas

Oura argues that the Customs ruling covered only the patent in the earlier dispute, not the two patents in the new suit. That is the gap the new case is built on, and it shows why a fresh patent matters even after the rival won customs clearance.

What each side says

Ultrahuman co-founder and chief executive Mohit Kumar said the company is confident in the Ring Pro's design and will defend its position "vigorously", noting that Oura chose to assert entirely new patents, one of them issued two days before filing. Ultrahuman says the Ring Pro remains on sale in the US, no injunction has been entered and its retail plans are unchanged. Oura says the ring "continues to infringe our intellectual property."

Because the suit has only just been filed, both statements are positions, not findings. Patent cases usually take many months to reach a decision, and a permanent injunction would come only at the end. Oura could, however, ask the court for a preliminary injunction sooner.

The wider market

Oura has pursued several rivals over ring patents, including Samsung, RingConn, Circular and Zepp, and RingConn and Circular agreed to pay royalties. The smart ring category is still small but growing quickly, which raises the stakes of every patent fight.

What it means in India

Ultrahuman is an Indian company, and there is a parallel case here: Ultrahuman sued Oura for patent infringement in the Delhi High Court in 2025, a single judge dismissed it citing non-disclosure of the ITC rulings, and a Division Bench later reinstated it. The current status of that case is not public. The Texas suit does not affect Ultrahuman's sales in India, and Oura's own Ring 5 is now on pre-order in India from Rs 39,900.

What to watch next

Ultrahuman's formal response in court, any request by Oura for a preliminary injunction, and whether the court accepts the two patents as valid. Developments in the Delhi case, and any new customs or trade commission action tied to the new patents, would also change the picture for buyers.
