Oura Sues Ultrahuman Again, Seeking to Block U.S. Sales of Ring Pro

OPA WIRE, Oct 23 (OPA) — Oura filed the complaint on Thursday, alleging that Ultrahuman’s Ring Pro infringes on two specific patents related to the device's design and internal components, including sensors and battery architecture. The lawsuit names both Ultrahuman and Plano, Texas-based manufacturer SVTronics as defendants. Oura is seeking a permanent injunction to block further U.S. sales of the product, arguing that the device relies on proprietary technology protected by its intellectual property.

The legal filing cites patents D804,471 and 12,769,363. The latter was issued to Oura on October 20, just two days before the lawsuit was initiated. An Oura spokesperson stated that the company is acting to protect its innovations, claiming that Ultrahuman has failed to address ongoing infringement despite a previous redesign of its hardware. Ultrahuman, which recently raised $70 million in a funding round, did not respond to requests for comment regarding the litigation.

This dispute follows a series of legal battles between the two companies that began in 2023. Ultrahuman previously faced an import ban on its Ring Air model after the U.S. International Trade Commission ruled in Oura’s favor last year. While Ultrahuman secured a favorable ruling from U.S. Customs and Border Protection in March regarding its redesigned Ring Pro, Oura contends that the current lawsuit addresses different patents not covered by that previous regulatory decision.

Oura has aggressively pursued patent claims against several competitors in the expanding smart-ring market, including Samsung, RingConn, and Circular. While some firms have opted to settle through licensing agreements, others remain in active litigation. The market for these wearables is projected to reach 6.3 million units by 2030, according to IDC data, as companies race to integrate advanced health metrics and AI-driven features into their hardware.
