Oura Sues Texas Manufacturer SVTronics to Stop Ultrahuman Ring Pro Sales

Oura has filed a federal lawsuit in Texas seeking to halt US sales of the Ultrahuman Ring Pro.

The complaint names both Ultrahuman and SVTronics, the Plano, Texas manufacturer that builds the device under Ultrahuman's direction. Oura alleges the Ring Pro infringes two patents covering design elements and internal components. The company is asking the court for monetary damages and a ban on US sales. One of the patents cited in the suit, number 12,769,363, was granted only two days before the complaint was lodged, according to TechCrunch.

This legal action follows a previous victory for Oura against the India-based rival. Last year, the US International Trade Commission ruled that the original Ultrahuman Ring Air violated several Oura patents. That decision resulted in a ban on US sales of the Ring Air, although the product remains available in Europe. Ultrahuman subsequently redesigned the device to avoid existing intellectual property claims. The new Ring Pro received approval from US Customs and Border Protection earlier this year, allowing it to re-enter the American market.

Oura argues the modifications were insufficient to clear its patent rights. The company stated on its blog that the redesign still incorporates many of its patented innovations. "After it was found to be infringing Oura patents, Ultrahuman recently introduced a modified version of its ring, claiming its redesign no longer infringed our patents. That claim is false," the company wrote. It added that the new ring continues to infringe its intellectual property.

Ultrahuman says it will contest the new lawsuit. A spokesperson told Engadget that the redesign has already undergone independent review in the United States. The company noted that Customs and Border Protection concluded the Ring Pro did not infringe the specific patent considered during that earlier proceeding. The spokesperson added that Oura has now chosen to assert different patents, including the one issued just before the suit was filed. The company said it would defend its position vigorously.

The Ring Pro remains on sale in the US while the legal dispute unfolds. This case adds to a period of frequent litigation for Oura. The company is also engaged in a prolonged patent fight with Samsung. In 2024, Samsung sued Oura preemptively over the Galaxy Ring, and Oura later filed a counter-suit against the South Korean tech giant. The two companies remained locked in that dispute as of this summer.

Oura recently announced a partnership with the US military that involves a Palantir hosting environment. The Texas suit marks the latest chapter in its efforts to protect its market position against competitors using similar wearable technology.
