Oura Files New Patent Suit Against Ultrahuman
Smart ring maker Oura has filed a fresh lawsuit against Indian rival Ultrahuman, seeking to block U.S. sales of the latter's Ring Pro. The move comes just months after the redesign helped the Bengaluru-based startup re-enter the American market following an import ban. The case is the latest in a series of patent disputes Oura has brought against competing smart-ring manufacturers, including Samsung and RingConn.
Allegations and Relief Sought
In a complaint filed Thursday in a federal court in Texas, Oura alleged that Ultrahuman's Ring Pro infringes two of its patents covering the ring's design and internal components, including its battery and sensors. Oura is seeking monetary damages and a permanent injunction that would bar Ultrahuman from selling the device.
Ultrahuman's Recent U.S. Re-entry
Ultrahuman's redesigned Ring Pro, launched in February 2026, received a favorable ruling from U.S. Customs and Border Protection in March, clearing the way for the startup's return to the U.S. market. That decision followed an import ban on Ultrahuman's earlier Ring Air, which took effect after Oura secured a patent infringement ruling from the International Trade Commission (ITC) in August 2025.
Oura's Position
"Ultrahuman has a history of copying Oura's innovations, as demonstrated by the 2025 ITC ruling against the company," an Oura spokesperson said in a statement to TechCrunch. "Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura's patents, seeking instead to capitalize on our innovation and the market leadership we have built."
Oura argues that the Customs ruling covered only the patent involved in the earlier dispute, not the two patents cited in its latest lawsuit: D804,471 and 12,769,363. "To protect its patent rights, Oura is now forced to file this complaint of patent infringement," the company said in its filing.
A Newly Issued Patent at the Center of the Case
One of the asserted patents, 12,769,363, is notably recent. It was issued to Oura on October 20, just two days before the company filed the lawsuit. The patent covers a smart-ring design incorporating internal components such as a curved battery, circuit board, magnets, and sensors.
Manufacturer Named as Co-Defendant
Oura has also named Texas-based electronics manufacturer SVTronics as a defendant. The complaint alleges that SVTronics manufactures the Ring Pro at a facility in Plano, Texas, purportedly under Ultrahuman's direction and control. It further alleges that both companies infringe Oura's patents through the manufacture, importation, and sale of the device in the U.S.
A Multi-Year Patent Fight
Oura and Ultrahuman have been locked in patent litigation since 2023, when Oura sued the Indian startup over its Ring Airβthe device that helped Ultrahuman establish a foothold in the U.S. Oura brought a separate case before the ITC in 2024, securing a ruling last year that led to the import ban on the Ring Air.
Broader Campaign Against Rivals
Ultrahuman is not the only competitor facing legal pressure from Oura. The company has also pursued patent infringement claims against smart-ring makers including Samsung, RingConn, Circular, and Zepp Health. Some of those disputes have ended in licensing agreements, with RingConn and Circular agreeing to pay royalties to Oura in order to sell their smart rings in the U.S.
