Oura Claims Ultrahuman Ring Pro Redesign Still Infringes Patents in New Texas Lawsuit
The complaint names the Indian startup and its Texas-based manufacturer, seeking a ban on US sales of the redesigned device.

Oura has filed a new lawsuit in a federal court in Texas, seeking to stop the US sale of Ultrahuman's Ring Pro. The complaint, posted on the company's blog on October 23, targets the wearable device that Ultrahuman launched after losing a previous legal battle over its Ring Air model.
The suit alleges that the Ring Pro infringes two specific Oura patents related to the device's design and internal components. Oura is requesting monetary damages and a court order preventing Ultrahuman from selling the product in the United States. This mirrors the remedy Oura secured in its earlier victory against the company.
The legal dispute stems from a ruling by the US International Trade Commission last year, which found that the Ring Air violated several Oura patents. That decision resulted in a ban on US sales of the Ring Air, though the device remains available in Europe and other regions. Ultrahuman, based in India, subsequently redesigned the ring to avoid the intellectual property claims in the American market. Earlier this year, US Customs and Border Protection approved the redesign.
Oura argues that the modifications were insufficient. In a blog post, the Finland-based company stated that Ultrahuman claimed the redesign no longer infringed its patents, but called that claim false. The company wrote that the new ring still incorporates many of Oura's patented innovations and continues to infringe its intellectual property.
TechCrunch reported that one of the patents cited in the suit, number 12,769,363, was granted just two days before the complaint was filed. This patent covers a smart ring design featuring a housing, a battery, and specific internal components. The Ring Pro for the US market is manufactured at a plant in Plano, Texas, by SVTronics under Ultrahuman's direction. Oura has named SVTronics as a co-defendant in the lawsuit.
Ultrahuman says it will contest the action and that the Ring Pro remains on sale in the US. A spokesperson told Engadget that the redesign has already undergone independent review in the United States. The spokesperson noted that Customs and Border Protection concluded in an earlier proceeding that the Ring Pro did not infringe the specific Oura patent considered at that time. The company stated that Oura has now chosen to assert different patents, including the one that issued just two days before the lawsuit, and said it would defend its position vigorously.
The case adds to a period of intense legal activity for Oura. The company recently announced a partnership with the US military involving a Palantir hosting environment. It is also engaged in a prolonged patent fight with Samsung. In 2024, Samsung preemptively sued Oura over concerns regarding the Galaxy Ring, and Oura later filed a suit against Samsung. As of this summer, the two companies remained locked in that dispute.
