Context: In 2022, Finnish wearable start-up initiated a patent enforcement campaign against three competitors – Ultrahuman, RingConn, and Circular – in the Western District of Texas and Eastern District of Texas. It filed additional petitions in the United States International Trade Commission (ITC) two years later, before dropping its case against Circular, after the two settled and signed a multi-year patent license agreement (June 25, 2024 Oura press release). Last week, the ITC issued a final determination, finding that both Ultrahuman and RingConn’s products infringe every element of every asserted claim of Oura’s U.S. Patent No. 11,868,178 (“Wearable computing device”), issuing a limited exclusion as well as cease and desist orders against the respondents (August 22, 2025 ip fray article).
What’s new: Ultrahuman has now clamped back against Oura, filing its own patent infringement suit in the Delhi High Court, alleging Oura’s Ring 4 brazenly copies its proprietary sensor integration and onboard processing technology (August 22, 2025 Ultrahuman press release).
Direct impact: Oura has already responded to the suit, which was made public on Friday, stating that it has “no merit” and is a “blatant attempt to distract” from their decisive U.S. defeat. “The facts are clear,” the Finnish start-up added, “Oura innovates, Ultrahuman imitates.”
Wider ramifications: In its press release, Ultrahuman also raised concerns around Oura’s transactions and business practices, referring to criticisms of “background deals” and a “pattern of indiscriminate assertion of patent infringement against any and all competitors”, perhaps in an effort to undercut the significance of the U.S. import ban it now faces. The company could still file an appeal against Thursday’s ITC ban in the Federal Circuit.
