Oura Blocks Ultrahuman Ring Pro in Texas Patent Lawsuit

Oura has filed a patent infringement lawsuit in Texas federal court seeking to stop Ultrahuman from selling its Ring Pro in the United States. The move targets the latest iteration of the wearable, which Ultrahuman launched after a previous model was barred from the American market. For US consumers, the suit introduces the risk of another sales halt for a popular smart ring if the court grants an injunction.

The complaint alleges that the Ring Pro infringes two specific Oura patents covering design and internal components. Oura is requesting monetary damages and a court order to block US sales of the device. The company named SVTronics, a Plano-based manufacturer that builds the US version of the ring under Ultrahuman's direction, as a co-defendant in the case.

Ultrahuman introduced the Ring Pro following a redesign intended to navigate around Oura's intellectual property. The new design received clearance from US Customs and Border Protection earlier this year, ending a review that determined the device did not infringe the specific patent at issue in that proceeding. Oura argues that the modifications were insufficient to avoid its broader patent portfolio.

"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," Oura stated in a blog post. The company added that the new ring still incorporates many of its patented innovations.

One of the patents cited in the suit, numbered 12,769,363, was granted just two days before the complaint was filed. TechCrunch reported that this patent broadly covers smart ring designs featuring a housing, a battery, and specific internal parts. Ultrahuman noted that Oura has now chosen to assert different patents than those considered in the earlier customs review.

An Ultrahuman spokesperson said the company will contest the action and that the Ring Pro remains on sale in the US. The spokesperson stated that the redesign has already been through independent review in the United States and that the company would defend its position vigorously. This legal action adds to a period of heightened litigation for Oura, which is also engaged in a prolonged patent dispute with Samsung.

The current suit follows a 2025 ruling by the US International Trade Commission that found the earlier Ring Air model violated several Oura patents. That decision led to a ban on US sales of the Ring Air, although the device remains available in Europe and other international markets. Oura's recent partnership with the US military, which involves a Palantir hosting environment, adds to the company's profile in the domestic tech sector.
