Key Takeaways:

• Oura has filed a new federal lawsuit against Ultrahuman’s Ring Pro, alleging infringement of two patents, including one issued just two days prior to the filing.
• This latest legal action marks a significant escalation in an ongoing patent dispute between the smart ring rivals, following an earlier U.S. import ban on Ultrahuman’s previous Ring Air.
• The battle unfolds within a rapidly growing smart ring market, with Oura aggressively defending its intellectual property against numerous competitors, including major players like Samsung, as Ultrahuman pushes for innovation and market expansion.

Smart Ring Showdown: Oura Ignites Fresh Patent War Against Ultrahuman’s Redesigned Ring Pro

The battle for dominance in the burgeoning smart ring market just got a fresh, litigious twist. Oura, the established leader in wearable health tech, has once again drawn its legal sword against Indian rival Ultrahuman, initiating a new federal lawsuit in Texas. The target? Ultrahuman’s redesigned Ring Pro, which had only recently navigated a tricky return to the U.S. market after an earlier import ban.

This new complaint, filed on Thursday in a federal court, sees Oura alleging that Ultrahuman’s Ring Pro infringes two distinct patents: D804,471 and 12,769,363. The D804,471 patent covers aspects of the ring’s design, focusing on its aesthetic and functional form factor. More intriguingly, patent 12,769,363, an exceptionally recent issuance from October 20th – just two days before the lawsuit was filed – pertains to the intricate internal architecture of a smart ring. This latter patent specifically describes the integration of components like a curved battery, circuit board, magnets, and an array of sensors within the compact ring structure, elements crucial to the advanced tracking capabilities of modern smart rings.

Oura isn’t merely seeking monetary damages; it’s pushing for a permanent injunction to halt all U.S. sales of the Ring Pro, a move that could severely impact Ultrahuman’s strategic presence in one of the world’s largest consumer markets. In a significant strategic move, Oura has also roped in Texas-based electronics manufacturer SVTronics as a co-defendant. The complaint alleges that SVTronics manufactures the Ring Pro at its Plano, Texas facility under Ultrahuman’s direction and control, thereby making both companies culpable for the alleged patent infringements through the manufacture, importation, and sale of the device in the U.S.

A History of Conflict: The Precedent of the Import Ban

This isn’t Oura’s first rodeo with Ultrahuman. The current legal skirmish is merely the latest chapter in a protracted intellectual property saga that began in 2023. Oura previously targeted Ultrahuman’s original Ring Air, leading to a crucial victory at the U.S. International Trade Commission (ITC) in 2024. That ruling, which found Ultrahuman’s Ring Air infringed on Oura’s patents, resulted in an import ban, effectively sidelining the Ring Air from the lucrative U.S. market and delivering a significant blow to the burgeoning startup.

Ultrahuman responded swiftly and strategically, redesigning its product and launching the Ring Pro in February. This redesigned version then secured a favorable ruling from U.S. Customs and Border Protection in March, paving the way for its cautious re-entry into the American market. However, Oura quickly countered this perceived victory, stating that the Customs ruling only addressed the specific patent involved in the earlier ITC dispute, leaving other potential infringements unaddressed. An Oura spokesperson articulated their unwavering stance: “Ultrahuman has a history of copying Oura’s innovations, as demonstrated by the 2025 ITC ruling against the company. Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura’s patents, seeking instead to capitalize on our innovation and the market leadership we have built.” Oura argues that their latest lawsuit targets these previously unaddressed patents, thereby necessitating the new legal action to protect their intellectual property rights.

Ultrahuman’s Defiant Stance and Market Ambitions

Unsurprisingly, Ultrahuman is preparing for a robust defense. Mohit Kumar, co-founder and CEO of Ultrahuman, expressed confidence in the Ring Pro’s unique design and its legal standing when speaking to TechCrunch. Kumar highlighted the strategic timing of Oura’s new patent: “Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed.” He affirmed their unwavering commitment to “address these claims through the appropriate legal process and will defend our position vigorously.” Crucially, Kumar reassured customers and stakeholders that “There is no court order affecting Ring Pro, and it remains available to customers in the U.S.,” signaling business as usual while the legal battle unfolds.

Ultrahuman’s determination is backed by significant momentum. In September, the startup successfully raised a substantial $70 million from investors, including Qualcomm Ventures and Labcorp, valuing the company at approximately $365 million. This capital infusion is fueling ambitious plans. Ultrahuman is not merely content with health and fitness tracking; they are actively collaborating with Qualcomm on next-generation smart rings capable of running more software directly on-device. This forward-looking strategy aims to expand beyond traditional health metrics into innovative areas such as AI interactions and even gaming, positioning Ultrahuman as a serious long-term player in the evolving wearable tech landscape.

Oura’s Broader Patent Strategy and the Expanding Market

Oura’s legal campaign extends far beyond Ultrahuman, painting a picture of a company fiercely protective of its intellectual property in a rapidly expanding market. The company has initiated patent infringement claims against a roster of competitors, including tech giants like Samsung, as well as emerging players such as RingConn, Circular, and Zepp Health. This aggressive stance has yielded tangible results in some instances, with disputes concluding in licensing agreements. RingConn and Circular, for instance, opted to pay royalties to Oura, allowing them to continue selling their smart rings while acknowledging Oura’s foundational patent rights. This strategy underscores Oura’s intent to either push competitors out of the market or force them into revenue-sharing agreements, cementing its position as the foundational innovator in the smart ring space and safeguarding its perceived leadership.

This escalating legal drama unfolds against a backdrop of a thriving, albeit increasingly competitive, smart ring market. Research firm IDC projects global smart ring shipments to surge by 12.8% this year, reaching 4.9 million units, with an anticipated climb to approximately 6.3 million by 2030. While Oura has undoubtedly pioneered the category and maintained a significant lead, the influx of new entrants, particularly well-funded startups like Ultrahuman and even behemoths like Samsung, signals a maturing market ripe for both innovation and intense conflict.

The lawsuit also arrives at a critical juncture for Oura, just weeks after it reportedly shelved its anticipated $2.2 billion IPO, citing “uncertainty” in the market. Such legal battles, while costly, can be viewed as a strategic maneuver to reinforce market dominance and reassure investors by safeguarding unique selling propositions and fending off competitors. Despite the IPO delay, Oura continues to innovate on the product front, recently adding new fitness metrics designed to provide deeper insights into cardiovascular health, demonstrating its commitment to product evolution alongside legal defense.

Implications and the Future of Smart Rings

The outcome of this latest lawsuit holds significant implications for both Oura and Ultrahuman, and indeed for the broader smart ring ecosystem. For Oura, a decisive victory would further solidify its intellectual property fortress, potentially deterring future competitors and affirming its pioneer status. However, a prolonged and expensive legal fight could also divert substantial resources and attention from critical product development and market expansion efforts. For Ultrahuman, successfully defending against these new allegations is paramount for its continued presence and growth in the vital U.S. market, particularly as it seeks to innovate beyond its current offerings and leverage its recent funding to scale.

Ultimately, such disputes highlight the inherent tension between protecting proprietary innovation—a cornerstone of technological advancement—and fostering a competitive environment where new players can introduce alternative solutions and drive the market forward. The legal skirmishes underscore that as wearables become increasingly sophisticated and integrated into daily life, the value of underlying technology and design patents will only grow, making the intellectual property battlefield as crucial as the consumer market itself.

Bottom Line:As the smart ring market expands its reach from niche health tracking to broader lifestyle and tech integration, expect the legal sparring to intensify. Oura’s aggressive defense of its patents, coupled with Ultrahuman’s determination to innovate and compete, signals that while technology evolves at lightning speed, the fundamental battles over intellectual property remain a cornerstone of market strategy. The true winner, ultimately, might be decided not just by court rulings, but by who can best balance legal protection with compelling innovation that captivates consumers and shapes the future of personal tech.
