The legal battleground in the smart ring market has intensified once more. Wearable technology pioneer Oura has reportedly filed a fresh lawsuit against its competitor, Ultrahuman, targeting the newly introduced Ultrahuman Ring Pro. In this latest legal action, Oura alleges that Ultrahuman has infringed upon several of its core design and internal component patents, a move that threatens to disrupt the rival company’s strategic comeback in the crucial United States market.
According to a report by TechCrunch, the core of Oura’s complaint centers on the hardware architecture of the Ring Pro. Specifically, Oura claims that Ultrahuman has unlawfully copied its proprietary designs regarding internal components such as the curved battery, circuit board, magnets, and sensors. The timing of the legal filing has also drawn significant attention within the tech industry. Oura was granted a specific internal-component patent—identified as patent number 12,769,363—on October 20, and the lawsuit was officially filed just two days later.
In a statement provided to TechCrunch, an Oura spokesperson did not mince words regarding its competitor’s track record, stating that Ultrahuman has a history of copying Oura’s innovations, as demonstrated by a previous 2015 International Trade Commission (ITC) ruling against the company. The spokesperson added that although Ultrahuman introduced a redesigned ring, it ultimately failed to address the continued infringement of Oura’s foundational patents. Beyond seeking to block the ongoing distribution and sale of the device, Oura is reportedly pursuing monetary damages in connection with the alleged patent violations.
For Ultrahuman, the timing could hardly be more delicate. The company has previously faced significant hurdles bringing its wearable products to consumers in the United States, most notably due to import restrictions and legal pressures that effectively forced its presence out of the country for a period. The Ultrahuman Ring Pro was designed to serve as the company’s major ticket back into the lucrative U.S. market, boasting an impressive 15-day battery life alongside advanced features like its bio-intelligent Jade AI. Oura’s latest legal maneuvers are clearly aimed at halting that momentum.
Despite the mounting legal pressure, Ultrahuman’s leadership remains defiant. Mohit Kumar, the co-founder and CEO of Ultrahuman, addressed the situation in comments to TechCrunch, pointing out the aggressive nature of Oura’s legal strategy. Kumar noted that Oura has chosen to assert entirely new and different patents, including the one that was officially issued just two days prior to the filing of the lawsuit. However, Kumar also confirmed that current court rulings have not imposed any injunctions or orders stopping Ultrahuman from selling the Ring Pro to consumers in the United States, meaning the device remains fully available for purchase.
The legal friction between these two companies is far from a sudden development and represents the latest chapter in an ongoing, multi-year feud across the global wearables landscape. The rivalry reached a notable peak in 2025, when Ultrahuman itself took legal action by filing a lawsuit against Oura. In that case, Ultrahuman accused Oura’s flagship Ring 4 of ripping off its own patented smart ring technology.
The heart of that earlier dispute revolved around core wellness metrics, specifically advanced sleep-tracking capabilities, circadian rhythm management tools, and specialized women’s health features. Ultrahuman maintained at the time that it had pioneered those specific wellness tracking mechanisms. Furthermore, the two companies have maintained starkly different business models, a contrast that has frequently fueled industry debates. While Ultrahuman offers its extensive suite of tracking features without a mandatory subscription paywall through its PowerPlugs software ecosystem, Oura has long relied on a subscription-heavy service model to unlock deeper insights for its users.
When Ultrahuman initiated its legal challenge against Oura in 2025, company representatives clarified that aggressively defending its patents was not necessarily its primary commercial goal. Instead, the company framed the move as an effort to position itself globally as a defender of open health data and to highlight Indian innovation on the international technology stage.
As the legal back-and-forth continues to unfold, Ultrahuman has pushed forward with expanding the software and health capabilities of its ecosystem throughout 2026. Earlier in the year, the company announced a strategic partnership with HealthEx designed to integrate users’ official medical records directly into the mobile application. This integration allows users to cross-reference the biometric and health data captured by their smart rings against their actual medical records, creating a more cohesive picture that can be easily shared with healthcare professionals. Additionally, the company rolled out a new Heart Scan feature specifically for the Ring Pro, requiring just sixty seconds of user interaction to deliver a vital, on-demand snapshot of cardiac health.
