A new legal challenge to Ring Pro
Oura has filed a patent lawsuit in federal court in Texas against Ultrahuman, seeking damages and an order that would block U.S. sales of the Indian company's Ring Pro. The complaint alleges that the device infringes two Oura patents related to smart-ring design and internal components, including its battery and sensors. The allegations have not been adjudicated.
The case comes months after Ultrahuman's redesigned Ring Pro received a favorable ruling from U.S. Customs and Border Protection, clearing the way for its return to the American market. The agency's decision followed an earlier import ban on Ultrahuman's Ring Air, imposed after a patent ruling by the U.S. International Trade Commission.
Oura says the customs decision addressed a different patent from the two cited in its new complaint. One of those patents, which covers arrangements of components such as a curved battery, circuit board, magnets and sensors, was issued on October 20--two days before the lawsuit was filed.
The complaint also names Texas-based manufacturer SVTronics, alleging that it makes Ring Pro at a facility in Plano under Ultrahuman's direction. Oura claims both companies infringe its patents through the device's manufacture, import and sale in the United States.
A competitive market shaped by innovation
The companies have been involved in patent disputes since 2023, when Oura first sued Ultrahuman over Ring Air. Oura has also pursued claims involving other smart-ring makers; some disputes in the category have concluded with licensing agreements.
Meanwhile, Ultrahuman is developing its business beyond health and fitness tracking, including work on a ring designed to support more software directly on the device. As smart rings expand into new uses, this case may help shape how intellectual property and product innovation coexist in the market.
