Oura patent blocks Ultrahuman Ring imports

The ruling showed that Ultrahuman was still a one product company in practice, not just on paper. More than half of revenue depended on shipping one ring into the U.S., so a patent loss did not just trim growth, it cut off the holiday sales window in the company’s biggest market until Ring PRO cleared customs in March 2026. That helps explain why revenue nearly stalled even as the broader smart ring category kept expanding.1 2 3 4

• The legal hit was specific and operational. The ITC found Ultrahuman Ring AIR infringed Oura’s patent, and Customs later ruled that the redesigned Ring PRO was outside the exclusion order, creating a real gap between the blocked product and the replacement product entering the U.S. market.5 6
• That gap mattered because the U.S. was the center of demand. Internal company research tied 61% of Ultrahuman revenue to the U.S., while the company profile shows smart rings made up more than 90% of operating revenue in the latest full fiscal year, leaving little else to absorb the shock.1 2
• The contrast with Oura is scale and resilience. Oura had already built a much larger ring business, reaching $1B of revenue in 2025 with an added subscription layer, so the same patent portfolio functioned as both offense against lower priced rivals and protection for its higher margin software plus hardware model.3 4

Going forward, Ultrahuman is likely to push harder toward a two layer model, with redesigned hardware that is safer to import and more paid software on top through Power Plugs. In smart rings, patent control and subscription attach are becoming as important as sensors, because they decide both who can sell in the U.S. and who keeps the best margins after the sale.1 3 5 6
