Oura Sues Ultrahuman Again, Right as Its Ring Finally Clawed Its Way Back Into the US

Oura has filed a new patent infringement lawsuit against Ultrahuman, arguing that the Ring Pro infringes two of its patents: one covering the ring's physical design, and another covering internal components like its curved battery and sensor layout, which Oura was awarded just two days before filing suit. Oura is asking for monetary damages and a permanent injunction that would block Ultrahuman from selling the ring in the US at all, and it also named SVTronics, the Texas manufacturer it says builds the Ring Pro on Ultrahuman's behalf.

This is round two. Oura sued Ultrahuman back in 2023 over its original Ring Air, then took the fight to the US International Trade Commission, winning a ruling in 2025 that got the Ring Air banned from import entirely. Ultrahuman came back in February with a redesigned Ring Pro, and in March, US Customs ruled the new design clear to sell, but only against the patent from the earlier case. Oura's new filing argues that ruling never touched these two patents, which is exactly the gap it's trying to close now.

The stakes are real: the Ring Pro is the only thing standing between Ultrahuman and a total exit from the US market, where it's building momentum off a recent $70 million raise at a roughly $365 million valuation. Oura, for its part, has made a habit of this. It's also sued Samsung, RingConn, Circular, and Zepp Health, with RingConn and Circular opting to settle and pay royalties rather than fight. "Ultrahuman has a history of copying Oura's innovations, as demonstrated by the 2025 ITC ruling against the company," an Oura spokesperson said. Ultrahuman did not respond to requests for comment.
