Overview
- Oura filed new complaints in U.S. court and at the ITC, naming Samsung, Zepp Health, Reebok and Nexxbase/Noise for alleged infringement of U.S. Patent No. 11,868,178.
- The suits target the Galaxy Ring, Amazfit Helio Ring, Reebok Smart Ring and Luna Ring, with Oura seeking royalties and potential import or sales bans.
- The asserted patent covers a ring form factor that places sensors, a flexible circuit and a curved battery between inner and outer layers to enable thin designs.
- Earlier actions on the same patent led Circular and Ringconn to take royalty-based licenses, while Ultrahuman is appealing an ITC cease‑and‑desist order blocking U.S. sales.
- Samsung previously argued Oura’s claims are overbroad and had a preemptive 2024 lawsuit dismissed in early 2025, and reports indicate it may try to invalidate the patent rather than license it.
