In 2025, Ultrahuman sued Oura. It accused Oura's Ring 4 of "ripping off its patented smart ring tech." The core of this dispute concerned "sleep tracking, circadian tools, and women’s health features." Ultrahuman said it "pioneered" those features. There was also a major difference between the two companies.While Ultrahuman offers its features without a paywall through PowerPlugs, Oura features a subscription-heavy model. Ultrahuman also clarified why it was suing Oura. It said that defending its patents wasn't the primary goal.
