Oura sues over two patents to block Ultrahuman Ring Pro sales in Texas
The Finnish wearable maker filed a complaint in federal court seeking a halt to US sales, naming the Plano, Texas manufacturer as a co-defendant.
By Pedro Barnes ·
Oura, a smart ring manufacturer based in Finland, filed a lawsuit in Texas federal court on October 23 to stop the US sale of Ultrahuman's Ring Pro. The complaint alleges the device infringes two specific patents held by Oura, which cover both the physical design and internal components of the wearable.
The company is seeking monetary damages and an injunction that would prevent Ultrahuman from selling the Ring Pro in the United States. This request mirrors the outcome of a previous dispute involving Ultrahuman's earlier model, the Ring Air.
The Ring Pro was introduced after Ultrahuman lost a prior legal battle. In 2025, the US International Trade Commission ruled that the Ring Air violated several Oura patents, leading to a ban on its US sales. Although the Ring Air remains available in Europe and other regions, Ultrahuman redesigned the device for the American market to avoid the cited intellectual property.
Ultrahuman, which is headquartered in India, stated that its redesign underwent independent review by US Customs and Border Protection earlier this year. The agency approved the changes after concluding the new design did not infringe on the specific patent considered during that earlier proceeding.
Oura disputes that the modifications were sufficient to clear its patents. In a blog post, the company wrote that the new ring "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property." The suit includes Patent 12,769,363, which was granted just two days before the complaint was filed.
The lawsuit names SVTronics, a manufacturing plant in Plano, Texas, as a defendant alongside Ultrahuman. SVTronics builds the Ring Pro for the US market under Ultrahuman's direction. Ultrahuman maintains that the device remains on sale in the US and that it will "defend our position vigorously." A company spokesperson noted that Oura has chosen to assert different patents, including the one issued shortly before the filing.
This legal action joins other ongoing disputes for Oura, including a patent fight with Samsung and a recent partnership with the US military involving a Palantir hosting environment.
