Key points
- Oura filed a patent infringement lawsuit against Ultrahuman in a federal court in Texas on Thursday, seeking to block U.S. sales of the Ring Pro.
- Oura says the Ring Pro infringes two patents, D804,471 and 12,769,363, covering the ring's design and internal components such as its battery and sensors.
- Ultrahuman CEO Mohit Kumar said there is no court order affecting Ring Pro and it remains available to customers in the U.S.
Smart ring maker Oura has sued Indian rival Ultrahuman again, seeking to block U.S. sales of its Ring Pro. The complaint was filed Thursday in a federal court in Texas. The redesign launched in February helped the Bengaluru startup return to the American market after an import ban.
Oura alleges the Ring Pro infringes two of its patents covering the ring's design and internal components, including its battery and sensors. The company is seeking monetary damages and a permanent injunction to stop Ultrahuman from selling the ring. Oura has also named Texas-based electronics manufacturer SVTronics as a defendant, saying it makes the Ring Pro in Plano, Texas, under Ultrahuman's direction and control.
What Oura said
Oura told TechCrunch that Ultrahuman has a history of copying its innovations. The company said the March Customs ruling covered only the patent involved in the earlier dispute, not the two patents cited in the new lawsuit. One of those patents, 12,769,363, was issued to Oura on October 20, two days before the suit was filed.

Ultrahuman's response
Ultrahuman co-founder and CEO Mohit Kumar said the startup was confident in the Ring Pro and would fight the allegations. He noted that Oura is asserting different patents, including one issued just two days before the lawsuit. Oura and Ultrahuman have been fighting over patents since 2023, when Oura sued over the Ring Air; an ITC ruling led to an import ban on that device in August last year.
