Oura Sues Ultrahuman Again to Block US Sales of Redesigned Ring Pro

Oura filed a federal lawsuit in Texas on Thursday seeking monetary damages and a permanent injunction to block US sales of Indian rival Ultrahuman's redesigned Ring Pro. The complaint alleges that the Ring Pro infringes two patents—D804,471 and 12,769,363, the latter issued on October 20—covering smart-ring design and internal components including a curved battery, circuit board, magnets, and sensors, which Oura argues were not covered by a March US Customs and Border Protection ruling that let Ultrahuman return to the US after an August 2025 International Trade Commission import ban on its earlier Ring Air. Oura also named Texas electronics manufacturer SVTronics as a defendant for allegedly manufacturing the Ring Pro in Plano under Ultrahuman's direction, weeks after Oura shelved a $2.2B IPO citing market uncertainty and shortly after Ultrahuman raised $70M in September at an approximately $365M valuation. IDC projects global smart-ring shipments will grow 12.8% this year to 4.9M units and reach about 6.3M by 2030, a market where Oura has previously extracted royalty licensing deals from rivals RingConn and Circular following patent disputes. "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 spokesperson.
