Oura targets SVTronics to halt Ring Pro sales

Oura has filed a new lawsuit in a Texas federal court against Ultrahuman and its contract manufacturer, SVTronics. The complaint alleges that the Ultrahuman Ring Pro, a smart ring released after the company’s earlier model was barred from the US market, violates two specific Oura patents. The company is seeking monetary damages and a court order to halt US sales of the device.

The legal conflict follows a ruling last year by the US International Trade Commission. That body determined that the original Ultrahuman Ring Air infringed on multiple Oura patents, resulting in a ban on its sale in the United States. While the Ring Air remains available in Europe and other regions, Ultrahuman redesigned the product to re-enter the American market. The new Ring Pro received clearance from US Customs and Border Protection earlier this year.

Oura disputes that the redesign successfully avoids its intellectual property. In a blog post, the company stated that Ultrahuman introduced the modified ring claiming it no longer infringed, a claim Oura called false. The firm argued that the new device still incorporates many of its patented innovations and continues to infringe its intellectual property.

One of the patents cited in the suit was granted just two days before the complaint was filed. According to reports from TechCrunch, Patent 12,769,363 covers a smart ring design featuring a housing, a battery, and specific internal components. The Ring Pro units sold in the US are manufactured by SVTronics at a plant in Plano, Texas, under Ultrahuman’s direction. Oura has named SVTronics as a co-defendant in the new action.

Ultrahuman says it will contest the lawsuit and that the Ring Pro remains on sale in the US. A spokesperson told Engadget that the redesign underwent independent review in the United States. The company noted that Customs and Border Protection previously concluded the Ring Pro did not infringe the patent considered at that time. The spokesperson added that Oura is now asserting different patents, including the one issued just two days before the suit, and that the company would defend its position vigorously.

This filing 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 dispute with Samsung. Samsung sued Oura in 2024, anticipating action against the Galaxy Ring. Oura later filed its own suit against Samsung, and the two companies remained locked in that dispute as of this summer.
