The legal battle lines in the burgeoning smart ring market have been drawn once again. Oura, a dominant pioneer in the wearable technology space, has reportedly initiated a fresh lawsuit against its prominent rival, Ultrahuman. The legal action alleges that Ultrahuman has infringed upon several key patents regarding both the design and internal components of its devices, specifically targeting the newly released Ultrahuman Ring Pro.
According to reports, the central point of contention revolves around fundamental hardware elements. Oura claims that Ultrahuman improperly copied its proprietary technology concerning curved batteries, internal circuit boards, magnets, and specialized sensors. This aggressive move threatens to disrupt Ultrahuman’s strategic comeback into the United States market, a region where the company has previously faced significant distribution hurdles, including import restrictions that severely limited its consumer footprint.
The timing of the lawsuit has also drawn considerable attention within the tech industry. Records show that Oura was officially granted a specific internal-component patent—identified as patent 12,769,363—on October 20. Merely two days later, Oura filed its fresh complaint in court, seeking not only to halt the alleged infringement but also pursuing monetary damages against its competitor.
An official spokesperson for Oura pulled no punches when addressing the ongoing intellectual property dispute, stating that Ultrahuman has a documented history of emulating Oura’s engineering innovations. The spokesperson pointed to a previous 2025 International Trade Commission (ITC) ruling against Ultrahuman as proof of past infractions, asserting that even though Ultrahuman introduced a redesigned ring, it ultimately failed to rectify the continued infringement of Oura’s protected intellectual property.
Ultrahuman, however, maintains that it is standing its ground. Mohit Kumar, the co-founder and chief executive officer of Ultrahuman, addressed the development directly, highlighting the aggressive and calculated timing of Oura’s legal maneuvers. Kumar noted that Oura has chosen to assert a shifting array of patents, notably including the one issued just forty-eight hours prior to the filing of the lawsuit. Despite the legal pressure, Kumar confirmed that current court rulings have not imposed any injunctions stopping Ultrahuman from selling the Ring Pro to consumers in the United States, allowing the device to remain actively available on the market.
A History of Escalating Rivalry and Conflicting Philosophies
This latest courtroom confrontation is merely the latest chapter in a protracted, multi-year rivalry between the two wearable tech companies. The competitive tension spilled into the open courts previously in 2025, when Ultrahuman launched its own legal offensive against Oura. In that action, Ultrahuman accused Oura of misappropriating its patented smart ring technology, specifically targeting Oura’s Ring 4.
The core of Ultrahuman’s 2025 complaint focused heavily on foundational software and analytical features, including advanced sleep tracking algorithms, circadian rhythm tools, and specialized health metrics tailored for women. At the time, Ultrahuman positioned itself as the original pioneer of these specific biointelligent features.
Beyond hardware and software disputes, the rivalry highlights a stark philosophical divide in how the two companies monetize their ecosystems and interact with their user bases. While Oura relies heavily on a subscription-based model that requires users to pay a recurring monthly fee to access their most comprehensive health insights, Ultrahuman has taken a drastically different path. Through its PowerPlugs ecosystem, Ultrahuman offers its core features and data interpretations without locking them behind a mandatory paywall.
Furthermore, Ultrahuman’s leadership has previously framed its legal strategy not merely as a defense of corporate turf, but as a broader mission to position the company as a champion of open health data and international technological innovation, particularly on the global stage.
As this corporate tug-of-war continues to evolve through both legal and commercial avenues, Ultrahuman has simultaneously pressed forward with expanding its product capabilities and ecosystem integrations. The company recently teamed up with HealthEx to allow users to securely pull their official medical records directly into the Ultrahuman application. This integration enables users to easily cross-reference the biometric data collected by their smart rings against clinical medical records, providing a more comprehensive health overview that can be shared directly with healthcare providers.
Additionally, Ultrahuman rolled out a specialized Heart Scan feature designed specifically for the Ring Pro. This diagnostic tool requires only sixty seconds of user engagement to deliver an immediate, high-level snapshot of cardiovascular health, showcasing the company’s continuous push to introduce advanced health-monitoring capabilities despite the ongoing legal clouds hovering over its U.S. operations.
