Oura has opened another legal front in its long-running patent fight with Ultrahuman, filing a new federal lawsuit that seeks to block U.S. sales of the Ultrahuman Ring Pro. The Oura Ultrahuman lawsuit, lodged Thursday in a federal court in Texas, asserts that the Ring Pro infringes two patents and asks for monetary damages and a permanent injunction.
The patents at the center of the case
The complaint cites U.S. Patent No. D804,471 and U.S. Patent No. 12,769,363. The first covers design elements of the ring, while the second extends to internal components including a curved battery, circuit board, magnets and sensors. That second patent is especially fresh: it issued on October 20, and Oura filed suit just two days later.
Ultrahuman launched the redesigned Ring Pro in February. In March, U.S. Customs and Border Protection issued a ruling favorable to the product. Oura argues that the customs decision addressed only an earlier patent, not the two now asserted in the Texas case. According to Oura, the redesign did not resolve the infringement issue.
SVTronics named alongside Ultrahuman
The lawsuit also names SVTronics, a Texas-based electronics manufacturer that produces the Ring Pro at a facility in Plano. Oura alleges that Ultrahuman directs and controls SVTronics’ production and that both companies infringe through the manufacture, import and sale of the device. SVTronics has not publicly responded to the complaint, and the brief does not indicate its position.
The case follows a separate action at the U.S. International Trade Commission. After an August ruling last year found patent infringement, an import ban hit the earlier Ring Air. Oura brought a separate ITC case in 2024. A spokesperson for Oura said Ultrahuman has a history of copying and pointed to the 2025 ITC ruling. The filing itself states that Oura was forced to act to protect its patent rights.
Ultrahuman says Ring Pro stays on sale
Ultrahuman CEO Mohit Kumar said the company is confident in the Ring Pro and will defend its position vigorously. He also said no court order currently affects the product and that the Ring Pro remains available in the United States.
The dispute between the two companies dates to 2023, when Oura sued Ultrahuman over the Ring Air. Oura has pursued similar claims against other smart ring makers, including Samsung, RingConn, Circular and Zepp Health. Some of those disputes ended in licensing deals: RingConn and Circular agreed to pay royalties to Oura.
A growing market and shifting corporate priorities
The legal clash unfolds in a smart ring market that IDC expects to grow 12.8% this year, reaching 4.9 million units shipped. By 2030, shipments are projected at about 6.3 million units. Oura remains a leading player, while Ultrahuman is a growing competitor.
Weeks before filing the lawsuit, Oura shelved a $2.2 billion IPO, citing market uncertainty. This week the company introduced new fitness metrics. Ultrahuman, based in Bengaluru, raised $70 million in September from investors including Qualcomm Ventures and Labcorp, reaching a valuation of about $365 million. It is also working with Qualcomm on a new smart ring that may run more software on the device, with an eye toward AI interactions and gaming.
The outcome of the new lawsuit is uncertain. The brief does not specify the amount of damages sought, the exact court in Texas or how SVTronics will respond. What is clear is that Oura is not relying on the earlier customs ruling to settle the matter. Instead, it is asking a federal court to decide whether the Ring Pro’s design and components cross the line into patent infringement.
