Oura has filed a new lawsuit against Indian competitor Ultrahuman, aiming to prevent U.S. sales of the latter’s Ring Pro smart ring. This legal action comes shortly after Ultrahuman's redesigned Ring Pro enabled the company to re-enter the American market following a prior import ban on its earlier device, Ring Air. Oura alleges that Ultrahuman’s Ring Pro infringes on two of its patents related to the design and internal components, including the battery and sensors, and is seeking monetary damages as well as an injunction to stop Ultrahuman’s sales.

Ultrahuman's Ring Pro launch in February received a favorable ruling in March by U.S. Customs and Border Protection, allowing market re-entry after a 2025 International Trade Commission decision resulted in the import ban of the original Ring Air device. Oura maintains that the recent lawsuit targets different patents from those involved in the earlier dispute, including one patented just two days before Oura filed the suit. The new complaint also names Texas-based manufacturer SVTronics, which reportedly produces the Ring Pro under Ultrahuman’s direction.

Ultrahuman CEO Mohit Kumar expressed confidence in the Ring Pro and stated the company would vigorously defend against the claims. He pointed out that the newly asserted patents appeared shortly before the lawsuit and confirmed no court order currently restricts Ring Pro sales in the U.S. The ongoing patent disputes between Oura and Ultrahuman began in 2023 and have seen Oura pursue similar legal actions against other companies like Samsung, RingConn, Circular, and Zepp Health, some of which resulted in licensing deals.

This renewed litigation unfolds amid a growing smart ring market, projected by IDC to reach 6.3 million units worldwide by 2030. Ultrahuman recently secured $70 million in funding from investors including Qualcomm Ventures, aiming to develop rings capable of running more advanced software directly on the device. Meanwhile, Oura continues to enhance its offerings, recently adding new fitness metrics and postponing its $2.2 billion IPO amid market uncertainties.
