Defendant
2 cases as defendant.
Oura Health Oy is a privately held Finnish health technology company founded in 2013. Headquartered in Oulu, Finland, with offices in Helsinki and San Francisco, the company has grown to over 900 employees. Oura is known for its flagship product, the Oura Ring, a smart ring designed to track sleep and physical activity. Since its inception, the company has raised over $1.3 billion in funding from investors including Fidelity Investments, Square, and Temasek. In early 2026, Oura Health initiated a legal restructuring to relocate its parent company to Delaware in the United States.
Oura's primary business is developing and selling wearable technology that monitors personal health metrics. The Oura Ring tracks biometric data such as sleep patterns, heart rate, body temperature, and blood oxygen levels using advanced sensors. This data is synchronized with a mobile application that provides users with personalized insights and scores related to their sleep, activity, and readiness. The company operates on a dual-revenue model, which includes the sale of the ring hardware and a monthly subscription for premium app features. Oura also offers enterprise solutions for corporate wellness programs and has established partnerships with organizations like the NBA, the U.S. military, and health tech companies like Dexcom.
As an operating company, Oura Health has recently become an active litigant to defend its market position. While the provided case data shows Oura as a defendant in two recent lawsuits, these appear to be counterclaims. Public reports indicate that Oura has been aggressively enforcing its own patent portfolio, having filed patent infringement complaints against several competitors in the smart ring market, including Samsung, Zepp Health, and others, in 2025.
The two tracked cases, both filed on April 21, 2026, in the Eastern District of Texas, are patent infringement lawsuits brought by Zepp Inc. and its North American subsidiary against Oura. These suits were filed after Oura had previously sued Zepp for patent infringement. Zepp's lawsuits allege that Oura's Ring Gen 3 and Gen 4 devices, along with the Oura mobile app, infringe on six of Zepp's patents related to motion recognition, sleep analysis, and other health-tracking technologies. This litigation reflects an escalating and active two-way patent dispute among major players in the growing smart ring technology sector.
The accused products are the Oura Ring and its companion mobile application, which work together as a wearable system to track a user's health and activity.
Zepp Inc. and its subsidiary, Zepp North America Inc., filed a lawsuit against Oura Health Oy. The complaint alleges that Oura's Ring Gen 3 and Gen 4 devices infringe upon six of Zepp's patents, including the '693 patent covering methods for determining measurement confidence from wearable sensors.
