Ōura Health Oy, commonly known as Oura, is a Finnish health technology company founded in 2013. Headquartered in Oulu, Finland, with additional offices in Helsinki and San Francisco, the company's parent entity is formally relocating to Delaware, USA, though European operations remain in Oulu. Oura is a private company, valued at approximately $11 billion in October 2025 following a $900 million Series E funding round. In May 2026, it confidentially filed for an Initial Public Offering (IPO) with the U.S. Securities and Exchange Commission. The company reported over $1 billion in revenue in 2025 and employs 1,355 people as of April 2026.
Oura specializes in wearable technology, primarily known for its Ōura Ring, a smart ring designed to track sleep, physical activity, and overall health. The ring utilizes advanced sensors, including infrared, red, and green LEDs, to measure over 50 health metrics such as heart rate, heart rate variability, body temperature, respiratory rate, blood oxygen levels, and movement. Data is transmitted via Bluetooth to a smartphone app, which provides personalized insights and daily scores for Sleep, Activity, and Readiness. Oura operates on a dual-revenue model, combining hardware sales of its rings (e.g., Oura Ring 4, launched in October 2024) with a monthly subscription for premium app features and offers enterprise solutions through "Oura for Business."
In terms of patent litigation, Ōura Health Oy maintains a defensive posture, with no tracked cases as a plaintiff and one as a defendant. The company is involved in an active patent infringement lawsuit, Omni MedSci, Inc. v. Samsung Electronics, Co. Ltd. et al., filed on December 20, 2024, in the Eastern District of Texas, a venue recognized for its plaintiff-friendly environment.
In this notable case, Omni MedSci, Inc. has sued Oura Health, alongside other defendants like Samsung, Fossil, and OnePlus, alleging infringement of patents related to wearable devices that measure physiological parameters and wirelessly transmit data. Oura Health filed a motion to dismiss, which was partially granted in March 2026 based on improper joinder.
