Oura Seeks US Sales Ban on Ring Pro in New Texas Patent Filing

Oura filed a complaint in Texas federal court on October 23 asking a judge to stop sales of Ultrahuman's Ring Pro in the United States. The Finland-based company is also seeking monetary damages. The filing names SVTronics, the Plano, Texas firm that builds the Ring Pro for the US market under Ultrahuman's direction, as a defendant alongside Ultrahuman.

The suit alleges that the Ring Pro violates two Oura patents, one covering design and another covering internal components. Patent 12,769,363, granted two days before the complaint was filed, appears to cover a smart ring housing with a battery and specific internal components. Oura's blog post describes the Ring Pro as a modified device that 'still incorporates many of Oura's patented innovations and continues to infringe our intellectual property.'

The case follows a 2025 loss for Ultrahuman at the US International Trade Commission, which found that the earlier Ring Air model violated several Oura patents and barred US sales of that product. The Ring Air remains on sale in Europe and other markets. Ultrahuman subsequently redesigned the Ring Pro to avoid Oura's patents, and US Customs and Border Protection cleared that redesign earlier this year.

A spokesperson for Ultrahuman said the company would 'defend our position vigorously' and that the Ring Pro remains available for purchase in the United States. The spokesperson said Customs and Border Protection had already reviewed the redesign and concluded in an earlier proceeding that it did not infringe the patent Oura raised at that time, and that Oura 'has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed.'

The filing adds to Oura's existing legal docket. The company is litigating a patent dispute with Samsung that began in 2024, when Samsung sued first over concerns about the Galaxy Ring, and Oura later countersued; the two were still disputing the matter as of this summer. Oura also recently announced a partnership with the US military involving a Palantir hosting environment.
