Oura seeks US sales ban on Ultrahuman Ring Pro in new patent suit

Oura has filed a lawsuit in a Texas federal court seeking to halt United States sales of the Ultrahuman Ring Pro. The complaint alleges that the smart ring infringes two patents held by the Finland-based company. Oura is asking the court for monetary damages and an order stopping the device from being sold in the US.

The legal action follows a previous dispute over Ultrahuman’s Ring Air. Last year, the US International Trade Commission ruled that the Ring Air violated several Oura patents. That decision led to a ban on US sales of the Ring Air, though the product remains available in Europe and other regions.

Ultrahuman, based in India, redesigned the Ring Pro to avoid the intellectual property claims that affected the earlier model. Earlier this year, US Customs and Border Protection approved the redesigned device for entry into the American market.

Oura argues that the changes were not enough to clear its patents. The company stated that the new ring still incorporates many of its patented innovations. Oura wrote that Ultrahuman’s claim that the redesign no longer infringed was false.

TechCrunch reported that one of the patents cited in the suit was granted only two days before the complaint was filed. Patent 12,769,363 covers a smart ring design with specific housing, battery, and internal components. The US version of the Ring Pro is manufactured at a plant in Plano, Texas, by SVTronics under Ultrahuman’s direction. Oura has named SVTronics as a co-defendant in the case.

Ultrahuman says it will contest the lawsuit and that the Ring Pro remains on sale in the US. A spokesperson told Engadget that the redesign has already undergone independent review in the United States. The spokesperson noted that Customs and Border Protection previously concluded the ring did not infringe the patent considered at that time. The company said it would defend its position vigorously.

The filing adds to a period of legal activity for Oura. The company recently announced a partnership with the US military involving a Palantir hosting environment. It is also engaged in a prolonged patent dispute with Samsung, which began in 2024 when Samsung sued Oura over concerns regarding the Galaxy Ring. The two companies remain in that dispute as of this summer.
