Overview
- Oura announced this week that it has lodged an ITC complaint and U.S. district court suits alleging infringement of U.S. Patent No. 11,868,178 by Samsung, Zepp Health/Amazfit, Reebok and Noise/Luna.
- The asserted patent covers a smart‑ring form factor that places sensors, electronics and a curved battery between inner and outer ring layers to enable a thin design.
- Earlier actions using the same patent led Circular, Ringconn and Omate to sign royalty‑based licenses, while Ultrahuman is appealing an ITC cease‑and‑desist restricting U.S. sales.
- Samsung’s 2024 preemptive lawsuit accusing Oura of overbroad patent claims was dismissed by a federal judge in early 2025, and Samsung has argued the patent is overly broad.
- The ITC process is underway, creating the prospect of U.S. import restrictions unless the accused firms redesign their rings, obtain licenses or succeed in challenging the patent.
