Oura kneecaps Ultrahuman with patents

The lawsuit mattered because it turned patents into a distribution weapon, cutting Ultrahuman off from the one market that was doing most of the work. After the U.S. trade ruling in October 2025 blocked imports of Ring AIR, Ultrahuman lost access to a country that represented 61% of revenue, then had to come back with a redesigned Ring PRO in March 2026 while Oura kept scaling toward IPO size.1 2 3 4 5

• This was not just a damages case. Oura took the fight to the ITC, where the remedy is import bans. The Commission found a violation on August 21, 2025, and the exclusion order took effect on October 21, 2025, which is much more disruptive for a hardware company than a normal patent suit.1 2 6
• The timing amplified the hit. Ultrahuman had pivoted from CGM into smart rings, the U.S. had become its largest market, and revenue growth then slowed sharply to about $69M for fiscal 2026 ending March 2026. The redesign and March 2026 U.S. return show the product path forward was to engineer around Oura, not wait out the case.1 4 7
• The competitive backdrop explains why Oura pressed so hard. By June 2026, Oura was at about $1.4B in TTM revenue and had filed its S 1 on September 3, 2026, while Whoop was already over $1.1B in annualized bookings. In a market this large, blocking lower priced no subscription rivals protects both growth and category control.3 5 8

Going forward, the smart ring market is likely to look more like medical devices or headphones, where IP, channel access, and insurer or retail partnerships matter as much as sensors. That favors scaled players like Oura, but Ultrahuman’s redesigned re entry shows there is still room for challengers that can ship around the patent fence and differentiate on pricing and software packaging.3 4 5 7
