Oura Targets Plano Manufacturer in New Texas Lawsuit

Oura has filed a new patent infringement lawsuit against Ultrahuman and its US manufacturing partner, seeking to block the sale of the Ultrahuman Ring Pro in the United States. The complaint was lodged in a federal court in Texas and names SVTronics, a company in Plano, Texas, as a defendant alongside the India-based Ultrahuman.

The legal action follows a previous victory for Oura, which won a case against Ultrahuman last year regarding the Ring Air. A US International Trade Commission ruling determined that the Ring Air violated multiple Oura patents, resulting in a ban on its sale in the US market. Ultrahuman subsequently redesigned its product to avoid these intellectual property claims, and the new Ring Pro received approval from US Customs and Border Protection earlier this year.

Oura argues that the redesign is insufficient to clear its patents. The company stated that the new ring still incorporates patented innovations and continues to infringe on its intellectual property. The suit cites two specific patents, one of which, Patent 12,769,363, was granted only two days before the complaint was filed. This patent covers a smart ring design featuring a housing, a battery, and specific internal components.

The Ring Pro for the US market is manufactured at a plant in Plano by SVTronics under Ultrahuman's direction. Oura is requesting monetary damages and a court order to stop Ultrahuman from selling the wearable in the US. The company is based in Finland, while its rival operates out of India.

Ultrahuman has not withdrawn the product from the market. A spokesperson for the company told Engadget that the redesign has already undergone independent review in the United States. The spokesperson noted that Customs and Border Protection previously concluded the device did not infringe the patent considered in that earlier proceeding. The company said it would defend its position vigorously against the new claims.

This lawsuit adds to a period of frequent 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, which began in 2024 when Samsung sued Oura pre-emptively over the Galaxy Ring. Oura later filed its own suit against Samsung, and the two companies remain in dispute as of this summer.
