Oura Files Texas Suit to Block Ring Pro Sales

Oura has sued Ultrahuman and SVTronics in a Texas federal court, seeking to stop US sales of the Ring Pro smart ring. The complaint alleges the device infringes two patents held by Oura, covering both its external design and internal components.

The legal conflict began last year when the US International Trade Commission ruled that Ultrahuman's Ring Air violated multiple Oura patents. That decision resulted in a ban on US sales of the Ring Air, though the product remains available in Europe and other regions. Following that loss, Ultrahuman redesigned its hardware to avoid the intellectual property claims in the American market.

In early 2026, US Customs and Border Protection approved the redesigned Ring Pro. However, Oura disputes that the changes are sufficient to avoid infringement. In a blog post, the company stated that the new ring "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property." Oura is currently seeking monetary damages and a court order to block US sales of the new model.

One of the patents cited in the suit, number 12,769,363, was granted just two days before the complaint was filed. TechCrunch reported that this patent broadly covers a smart ring design featuring a specific housing, battery, and internal components. The US version of the Ring Pro is manufactured in Plano, Texas, by SVTronics under Ultrahuman's direction. Oura has named SVTronics as a defendant in the new action.

Ultrahuman said it will contest the lawsuit and confirmed that the Ring Pro remains on sale in the US. A spokesperson for the India-based company told Engadget that the redesign "has already been through independent review in the United States." The spokesperson noted that Customs and Border Protection previously found the device did not infringe the patent considered at that time. The company added that Oura "has now chosen to assert different patents" and that Ultrahuman would "defend our position vigorously."

This filing adds to a period of frequent legal activity for Oura. The company recently announced a partnership with the US military that utilizes a Palantir hosting environment. Oura is also engaged in a patent dispute with Samsung. In 2024, Samsung sued Oura preemptively, and Oura subsequently filed its own suit against Samsung. As of this summer, the two companies remained in that ongoing legal battle.
