Oura Sues Ultrahuman Again, Challenging Its U.S. Smart Ring Comeback

Oura filed a patent infringement lawsuit against Ultrahuman in the U.S. District Court for the Eastern District of Texas on October 22, 2026. Docketed as Case No. 2:26-cv-00953, the 29-page complaint names Ultrahuman Healthcare Inc., Ultrahuman Healthcare Pvt. Ltd., and Texas-based contract manufacturer SVTronics, Inc.

The legal action challenges Ultrahuman's effort to rebuild its U.S. business after regulatory setbacks. Following a U.S. International Trade Commission exclusion order that blocked imports of the Ring AIR in late 2025, Ultrahuman introduced the Ring Pro. In March 2026, U.S. Customs and Border Protection cleared the Ring Pro for import after determining it fell outside the exclusion order. Oura is now challenging the device directly in federal court, arguing the Customs clearance was neither final nor comprehensive.

Market Share Shifts and Previous ITC Action

The previous regulatory dispute reshaped the market. IDC data indicates Ultrahuman's U.S. market share dropped from 24.6% in the second quarter of 2025 to single digits following the import ban, while Oura expanded its share to roughly 85%. Ultrahuman reported that the ITC exclusion order resulted in up to $50 million in lost sales.

Ultrahuman maintains that the Ring Pro relies on a non-infringing architecture cleared by federal authorities. CEO Mohit Kumar previously asserted that the startup develops its hardware independently and would defend its products in court. Oura CEO Tom Hale had stated that the company will act to defend its intellectual property whenever it believes proprietary technology has been copied.

Targeting Texas Assembly and SVTronics

By naming SVTronics as a co-defendant, Oura is targeting the operational partner behind Ultrahuman's domestic supply chain. SVTronics operates an electronics manufacturing facility in Plano, Texas, which Ultrahuman partnered with to establish a U.S. production footprint. The new legal challenge introduces uncertainty over product fulfillment and domestic support for the Ring Pro, which was introduced with a price range between $349 and $399.

Federal Case Assigned in Marshall

The action has been assigned to District Judge Rodney Gilstrap and referred to Magistrate Judge Roy S. Payne. It represents the third patent infringement case involving the companies in the Eastern District of Texas, following lawsuits filed in September 2023 and September 2025. The court has not yet ruled on whether it will issue preliminary injunctive relief affecting the sale or domestic assembly of the Ring Pro.
