Oura Asks Texas Court to Halt US Sales of Ultrahuman's Newest Ring

Oura filed suit in a Texas federal court this week asking a judge to bar sales of Ultrahuman's Ring Pro in the United States and to award damages over two patents the company says cover the device's design and internal parts. The complaint names SVTronics, the Plano, Texas company that builds the Ring Pro for the US market under Ultrahuman's direction, as a defendant alongside Ultrahuman.

The dispute started last year, when Oura won a case against Ultrahuman and the US International Trade Commission found that Ultrahuman's Ring Air violated several Oura patents. That ruling blocked sales of the Ring Air in the United States; the device remains on sale in Europe and other markets. Ultrahuman, based in India, then redesigned a new ring for the American market, and US Customs and Border Protection cleared that version earlier this year.

Oura says the redesign did not go far enough. "After it was found to be infringing Oura patents, Ultrahuman recently introduced a modified version of its ring, claiming its redesign no longer infringed our patents. That claim is false," the company wrote on its blog, adding that the new ring "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property." One of the two patents in the complaint, No. 12,769,363, was granted two days before the suit was filed.

The Ring Pro remains on sale in the United States while the case proceeds. A spokesperson for Ultrahuman said the company would "defend our position vigorously," and noted that Customs and Border Protection had already examined the device in an earlier proceeding and concluded that it did not infringe the patent raised at that time. The spokesperson also said Oura "has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed." The spokesperson said the redesign "has already been through independent review in the United States."

Oura's litigation activity has expanded beyond Ultrahuman. The company announced a partnership with the US military involving a Palantir hosting environment, and it is separately in a patent dispute with Samsung that began in 2024, when Samsung filed first over concerns that Oura planned to act against the Galaxy Ring; Oura later countersued. The two companies were still in that dispute as of this summer.
