Oura has sued Ultrahuman again, this time over the Ring Pro, the ring Ultrahuman redesigned so it could keep selling in the US. The suit was filed in federal court in Texas. Oura wants money, and it wants the Ring Pro off US shelves.
The first fight went Oura's way. The US International Trade Commission ruled that Ultrahuman's Ring Air broke several Oura patents, and the Ring Air was pulled from US sale. It's still sold in Europe and other markets. Ultrahuman then reworked the Ring Pro to steer clear of those patents, and US Customs and Border Protection approved it earlier this year.
"Ultrahuman's latest ring still incorporates many of Oura's patented innovations and continues to infringe our intellectual property," Oura wrote on its blog. Ultrahuman's claim that the new design no longer infringes, the company added, "is false."
The new case rests on two different patents, covering the ring's design and the parts inside it. TechCrunch reported that one of them was granted just two days before Oura filed. That patent, number 12,769,363, reads broadly: a ring with a housing, a battery and particular parts inside.
Oura also named SVTronics as a defendant. SVTronics builds the Ring Pro for Ultrahuman's US sales at a plant in Plano, Texas.
Ultrahuman's chief executive, Mohit Kumar, said the company will fight. "Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," he told TechCrunch. "We will address these claims through the appropriate legal process and will defend our position vigorously."
Samsung is in the same kind of fight with Oura. It sued Oura first in 2024, worried Oura would come after the Galaxy Ring, and Oura then did sue Samsung. As of this summer the two were still at it over patents.
Ultrahuman says the Ring Pro is still on sale in the US, and filing a lawsuit doesn't change that. Only a court can. The last time this went all the way, a ruling took the Ring Air off US shelves, and Oura is asking for the same result for the Ring Pro.
