Oura Sues Ultrahuman Again, Seeking to Pull the Texas-Built Ring Pro Off U.S. Shelves

Oura says Ultrahuman's redesigned smart ring still infringes two of its patents, one issued just two days before the suit. Ultrahuman says it will fight, and the Ring Pro stays on sale for now.

PLANO, Texas - Oura has gone back to court against Ultrahuman, asking a federal judge to stop U.S. sales of the redesigned smart ring that brought the Indian company back to the American market. In a complaint filed on Oct. 22 in the U.S. District Court for the Eastern District of Texas, Oura alleged that Ultrahuman’s Ring Pro infringes two of its patents covering the ring’s design and its internal components, TechCrunch reported. Oura is seeking damages and a permanent injunction.

The case reopens a fight Ultrahuman thought it had settled with engineering. Its earlier Ring Air was barred from import into the United States after Oura won a ruling at the International Trade Commission in 2025. Ultrahuman launched the reworked Ring Pro in February and received a favorable ruling from U.S. Customs and Border Protection in March, clearing its return. Oura argues that ruling covered only the patent in the earlier dispute, not the two it now asserts, design patent D804,471 and utility patent 12,769,363.

The timing of the second patent stands out. Patent 12,769,363 was issued to Oura on Oct. 20, two days before the company filed suit, according to TechCrunch. It covers a smart ring built around internal parts including a curved battery, a circuit board, magnets and sensors.

The suit also lands close to home for the Ring Pro. Oura named SVTronics, an electronics manufacturer that it says builds the ring at a plant in Plano under Ultrahuman’s direction, as a co-defendant. “Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura’s patents,” an Oura spokesperson told TechCrunch. In a blog post, Oura said that “changing a product to sidestep one patent does not give Ultrahuman the right to use the rest of Oura’s innovations.”

Ultrahuman says it will fight. “Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed,” Mohit Kumar, Ultrahuman’s co-founder and chief executive, told TechCrunch. “There is no court order affecting Ring Pro, and it remains available to customers in the U.S.”

For buyers, nothing changes yet. The Ring Pro remains on sale in the United States until a court orders otherwise, and Ultrahuman’s rings are unaffected in other markets, GSMArena noted. Oura has also pursued patent claims against Samsung, RingConn, Circular and Zepp Health, and RingConn and Circular now pay it royalties. The suit comes as Oura pushes its Ring 5, which went on sale in India on Oct. 22, and weeks after Ultrahuman added free on-demand heart rhythm checks to its rings.
