Oura Claims Ring Pro Redesign Still Infringes

Oura has filed a new lawsuit in Texas federal court.

The complaint targets Ultrahuman's Ring Pro, a device the Indian company launched after losing a previous dispute over its Ring Air. Oura alleges the new product violates two of its patents related to design and internal components. The company is seeking monetary damages and wants a court order to stop US sales of the Ring Pro.

This legal battle follows a win Oura secured last year. The US International Trade Commission ruled that the original Ring Air infringed on several Oura patents, leading to a sales ban in the United States. The Ring Air is still sold in Europe and other regions. Ultrahuman redesigned the hardware to avoid those specific issues and received clearance from US Customs and Border Protection earlier this year.

Oura disputes that the changes were enough. The company stated that Ultrahuman claimed its redesign no longer infringed on patents, but Oura called that claim false. It argued the new ring still uses many of Oura's patented innovations.

One of the patents cited in the suit was granted just two days before the complaint was filed. That patent, number 12,769,363, covers a smart ring housing, battery, and specific internal parts. The Ring Pro is manufactured in Plano, Texas, by SVTronics. Oura included SVTronics as a defendant in the filing.

Ultrahuman says it will fight the case and the Ring Pro remains available for purchase in the US. A spokesperson told Engadget that the redesign underwent independent review in the country. The company noted that Customs and Border Protection previously found the Ring Pro did not infringe the patent considered during that earlier proceeding. The spokesperson added that Oura is now asserting different patents, including the one issued right before the suit was filed, and said Ultrahuman would defend its position vigorously.

This case adds to recent legal activity for Oura. The company recently announced a partnership with the US military involving a Palantir hosting environment. It is also involved in a patent dispute with Samsung, which began in 2024 when Samsung sued Oura first. Both companies remained in that conflict as of this summer.
