Oura files Texas suit to block Ultrahuman Ring Pro

Oura has filed a new patent infringement lawsuit against Ultrahuman in a federal court in Texas. The complaint targets the Ring Pro, a wearable device Ultrahuman launched after a previous model was blocked from the US market.

According to a post on the company's blog, Oura alleges that the Ring Pro violates two of its patents related to design and internal components. The Finland-based firm is seeking monetary damages and a court order to halt US sales of the device.

The legal conflict stems from a dispute over Ultrahuman's earlier product, the Ring Air. Last year, the US International Trade Commission found that the Ring Air infringed on multiple Oura patents. That decision resulted in a ban on US sales of the Ring Air, though the product continues to sell in Europe and other regions.

Ultrahuman, which is headquartered in India, redesigned the Ring Pro to avoid those intellectual property rights. The new design received approval from US Customs and Border Protection earlier this year. Oura disputes that the changes were enough. The company stated in its blog post that the redesign "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property."

TechCrunch reported that one of the patents at issue, number 12,769,363, was granted only two days before Oura filed the complaint. The patent covers a smart ring housing, battery, and specific internal parts. Oura also named SVTronics as a defendant. The Plano, Texas, company manufactures the US version of the Ring Pro under Ultrahuman's direction.

An Ultrahuman spokesperson told Engadget that the company will contest the action. The spokesperson noted that the Ring Pro remains on sale in the US and that the redesign underwent independent review by Customs and Border Protection. That agency previously concluded the device did not infringe the specific patent considered in the earlier proceeding. The spokesperson said Ultrahuman would "defend our position vigorously" against the new claims.

This lawsuit adds to a period of intense 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 ongoing patent dispute with Samsung, which began in 2024 when Samsung preemptively sued Oura over concerns regarding the Galaxy Ring.
