Oura Files Texas Suit to Halt Ultrahuman Ring Pro Sales

Oura has sued Ultrahuman and SVTronics in a Texas federal court to stop US sales of the Ring Pro.

The legal dispute began last year when the US International Trade Commission ruled that the Ring Air violated several Oura patents. That decision resulted in a US sales ban for the earlier model, though it remains available in Europe and other regions. Ultrahuman then redesigned the device to bypass the existing intellectual property claims. Earlier this year, US Customs and Border Protection approved the new design after an independent review.

Oura argues the changes were insufficient. A company post states that the Ring Pro "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property." The Finland-based firm seeks monetary damages and a court order to block US sales of the new wearable.

The complaint targets two specific patents. TechCrunch reported that one of them, Patent 12,769,363, was granted only two days before the lawsuit was filed. This patent covers a smart ring design featuring a housing, a battery, and specific internal components. The Ring Pro for the US market is manufactured at a plant in Plano, Texas, by SVTronics under Ultrahuman's direction. Oura included SVTronics as a defendant in the new filing.

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

This case adds to a period of intense legal activity for Oura. The company recently announced a partnership with the US military that uses a Palantir hosting environment. Oura is also engaged in a prolonged patent fight with Samsung. Samsung sued Oura in 2024 over concerns regarding the Galaxy Ring, and Oura later filed its own suit against Samsung. As of this summer, the two companies remained in that dispute.
