Overview
- Ultrahuman lodged a patent infringement case in the Delhi High Court alleging the Oura Ring 4 copies architecture protected by an India Patent Office grant tied to its Ring Air.
- Court filings reference a layered ring structure with heart-rate, temperature, and motion sensors and a microcontroller that processes data for sleep stages and readiness scores.
- Ultrahuman claims Oura replicated features it touts as breakthroughs, including women’s health tracking, circadian tools, and glucose-related capabilities, then placed them behind a subscription paywall.
- Oura responded that the India case lacks merit, pointing to a prior U.S. International Trade Commission ruling it says found Ultrahuman infringed and led to exclusion and cease-and-desist orders, with a final ITC decision expected in November 2025.
- The dispute now spans U.S. and Indian venues and underscores contrasting business approaches, as Ultrahuman promotes no mandatory subscription and modular add-ons while Oura relies on a subscription model.
