Oura has filed a new patent infringement lawsuit against Ultrahuman in a Texas federal court. The complaint alleges that the Ring Pro model violates two of Oura’s patents related to design, sensors, and battery technology.
Oura is seeking monetary damages and a permanent injunction to block U.S. sales of the Ring Pro. The lawsuit also names the Texas-based manufacturer SVTronics as a defendant, claiming it produces the device under Ultrahuman’s control.
The legal action follows a previous dispute that led to an import ban on Ultrahuman’s earlier Ring Air model in 2025. While Ultrahuman secured a favorable ruling for its redesigned Ring Pro from U.S. Customs in March, Oura argues this does not cover the new patents cited.
Oura has been actively litigating against several competitors in the smart-ring sector, including Samsung, RingConn, Circular, and Zepp Health. Some of these disputes have resulted in royalty agreements, while Oura recently shelved its planned 2.2 billion USD IPO.
Ultrahuman recently raised 70 million USD in a funding round led by investors including Qualcomm Ventures and Labcorp, reaching a valuation of 365 million USD. The company is currently collaborating with Qualcomm on a new smart-ring project.
