Oura alleges that the device infringes two patents covering its design and technology, despite receiving US Customs clearance earlier this year. “Changing a product to sidestep one patent does not give Ultrahuman the right to use the rest of Oura’s innovations,” Oura said in a statement. Ultrahuman told CNET it remains confident in the product and will continue manufacturing and selling it while defending the new claims. “We will address Oura’s newly asserted claims through the appropriate legal process and will defend our position vigorously,” an Ultrahuman spokesperson said. Oura has filed another patent lawsuit against Ultrahuman. The complaint, filed this month in the US District Court for the Eastern District of Texas, targets the redesigned Ultrahuman Ring Pro and names its Texas manufacturing partner, SVTronics, as a defendant. The dispute centres on whether the redesigned ring infringes patents beyond the one Customs reviewed. “Competition and intellectual property disputes are a natural part of building an important new technology category.

What the earlier ruling and Customs clearance covered
D804,471 and 12,769,363 as the patents allegedly infringed by the Ring Pro. The earlier ruling against Ultrahuman concerned a different patent. Oura first sued Ultrahuman in Texas in September 2023 over the Ring Air. The company followed with a complaint to the US International Trade Commission in March 2024. In August 2025, the commission found that Ultrahuman’s smart rings infringed specified claims of Oura’s US Patent No. 11,868,178 and issued orders restricting imports. Ultrahuman subsequently sought a Customs ruling on its redesigned Ring Pro. Customs determined on March 6, 2026, that the redesigned device did not infringe that patent. Oura’s filing acknowledges that clearance but says the review addressed only the earlier patent, according to the new complaint.
The company said the redesign does not resolve its larger intellectual property problems. “Ultrahuman’s latest ring still incorporates many of Oura’s patented innovations and continues to infringe our intellectual property,” the company said. It did not consider the two patents asserted in the latest lawsuit. The complaint alleges that Ultrahuman began US sales of the Ring Pro in May, with shipments starting in June. Ultrahuman told CNET that the court had not yet ruled on Oura’s latest complaint and that it would continue manufacturing and sales. The complaint identifies US Patent Nos. The lawsuit asserts both design and utility patents, which concern a product’s appearance and how an invention works, respectively. Oura is seeking monetary damages and a permanent injunction to stop Ultrahuman from selling the accused ring. Those are allegations in the new dispute.
