Oura sues to block US sales of Ultrahuman Ring Pro
A new federal complaint in Texas cites two patents, one granted just 48 hours before the filing.
By Katherine Barnes ·
Oura is asking a Texas federal court to stop Ultrahuman from selling the Ring Pro in the United States. The company filed the lawsuit today, alleging that the new smart ring infringes two of its patents.
The complaint targets the Ring Pro, a product Ultrahuman launched after losing a previous legal battle over its earlier model, the Ring Air. That earlier dispute ended with a US International Trade Commission ruling that the Ring Air violated Oura's intellectual property, leading to a ban on its US sales. Ultrahuman, based in India, redesigned the device to circumvent those specific patents.
The new suit argues that the modifications were insufficient. Oura stated on its blog that the Ring Pro still incorporates many of its patented innovations. The company is seeking monetary damages and a court order to halt US sales.
One of the two patents cited in the complaint, Patent 12,769,363, was granted just two days before the lawsuit was filed. This patent covers a smart ring design featuring a housing, a battery, and specific internal components. TechCrunch reported the timing of the patent grant.
The Ring Pro for the US market is manufactured in Plano, Texas, by SVTronics under Ultrahuman's direction. Oura has named SVTronics as a co-defendant in the case. Earlier this year, US Customs and Border Protection approved the redesigned Ring Pro, concluding it did not infringe the patents considered during that earlier proceeding.
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 been through independent review in the United States. The company noted that Oura is now asserting different patents, including the one issued just two days before the lawsuit, and said it would defend its position vigorously.
The lawsuit adds to a period of heightened 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, which began in 2024 when Samsung preemptively sued Oura over the Galaxy Ring.
