Oura Asks Texas Court to Block Sales of Ultrahuman's Ring Pro

Oura has sued Ultrahuman in federal court in Texas to stop U.S. sales of the Ring Pro, the redesigned smart ring Ultrahuman released after losing an earlier patent fight over its Ring Air. The complaint asks for damages and an injunction halting sales of the device in the American market.

The Finnish company alleges the Ring Pro violates two of its patents, one covering ring design and another covering internal components. One of the patents, No. 12,769,363, covers a smart ring with a housing, a battery and specific internal parts. That patent issued on Oct. 21, two days before the complaint was filed on Oct. 23.

The Ring Pro sold in the U.S. is assembled at a plant in Plano, Texas, operated by SVTronics under Ultrahuman's direction. Oura named SVTronics as a defendant alongside Ultrahuman. Oura said in an Oct. 23 blog post that Ultrahuman's redesign does not clear the patents. "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," the company wrote, adding that the new ring "still incorporates many of Oura's patented innovations and continues to infringe our intellectual property."

Ultrahuman, based in India, said it will fight the case and that the Ring Pro remains on sale in the U.S. A spokesperson said the redesign "has already been through independent review in the United States" and that U.S. Customs and Border Protection concluded in an earlier proceeding that the Ring Pro did not infringe the patent raised at that time. The spokesperson said Oura "has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," and added that the company would "defend our position vigorously."

The litigation follows an earlier round between the two companies. In 2025, the U.S. International Trade Commission found that Ultrahuman's Ring Air violated several Oura patents, and U.S. sales of the Ring Air were banned. The Ring Air remains on sale in Europe and other markets. Ultrahuman redesigned the Ring Pro to address those claims, and U.S. Customs and Border Protection cleared the redesign earlier this year.

Oura is also in a patent dispute with Samsung that began in 2024, when Samsung filed first over concerns Oura would move against the Galaxy Ring; Oura later countersued, and the two companies were still in litigation as of this summer. Oura also announced a partnership involving a Palantir hosting environment for the U.S. military.
