Oura Sues to Halt US Sales of Ultrahuman's Ring Pro in Texas Court

Oura has gone back to court against Ultrahuman, seeking to stop sales of the Ring Pro in the United States. The Finland-based company filed the complaint in a Texas federal court, alleging the device infringes two of its patents covering design and internal components. The request for a court order blocking US sales mirrors the outcome Oura obtained against a different Ultrahuman product.

The dispute traces to an earlier fight over the Ring Air. The US International Trade Commission ruled last year that the Ring Air violated several Oura patents, and that decision led to a ban on US sales of the model. The Ring Air remains available in Europe and other markets. Ultrahuman, based in India, then redesigned the Ring Pro to avoid Oura's intellectual property in the American market, and US Customs and Border Protection approved the redesign earlier this year.

Oura contests whether those changes were sufficient. The company wrote that after being found to be infringing Oura patents, Ultrahuman introduced a modified version and claimed the redesign no longer infringed. Oura called that claim false, adding that the new ring "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property." The company is seeking damages along with the sales ban.

One of the two patents in the suit, No. 12,769,363, was granted two days before the complaint was filed, according to TechCrunch. The patent covers a smart ring design with a housing, a battery and specific internal components. The Ring Pro sold in the US is manufactured at a plant in Plano, Texas, by SVTronics under Ultrahuman's direction, and Oura named SVTronics as a defendant in the case.

Ultrahuman has said it will contest the action and that the Ring Pro remains on sale in the US. A spokesperson said the redesign "has already been through independent review in the United States," and that Customs and Border Protection concluded after an earlier proceeding that the Ring Pro did not infringe the Oura patent considered at that time. The spokesperson added that Oura "has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," and that the company would "defend our position vigorously."

The filing adds to a stretch of legal activity for Oura, which recently announced a partnership with the US military involving a Palantir hosting environment. The company is also in a patent dispute with Samsung that began in 2024, when Samsung sued Oura over concerns about the Galaxy Ring; Oura later filed its own suit against Samsung, and the two companies remained in that dispute as of this summer.
