Oura Sues Ultrahuman Again to Block Ring Pro from US Market
Oura Sues Ultrahuman Again to Block Ring Pro from US Market
Smart ring maker Oura has filed a new federal lawsuit against rival Ultrahuman in Texas, seeking to block US sales of the Ring Pro just months after a redesign allowed the startup to return to the American market. Oura alleges that the new device infringes two of its patents, including one issued just two days before the complaint was filed.
The legal battle in the wearable technology market has escalated as Finland-based Oura files a fresh patent infringement lawsuit against India-based competitor Ultrahuman. The complaint, lodged in a Texas federal court, targets Ultrahuman's newly introduced Ring Pro and seeks monetary damages alongside a permanent sales ban. This follows a previous International Trade Commission ruling that successfully banned Ultrahuman's earlier Ring Air model in the United States. Although Ultrahuman previously modified its hardware to secure US Customs and Border Protection approval, Oura argues that the latest iteration still incorporates protected designs and internal components.
Escalating Legal Conflict in Texas Federal Court
Oura has initiated a new legal challenge against its rival Ultrahuman, filing a patent infringement complaint in a Texas federal court. The dispute centers on Ultrahuman's Ring Pro, which Oura claims violates two distinct intellectual property assets concerning internal components and physical design.
This aggressive legal maneuver arrives shortly after Ultrahuman managed to re-enter the American market following an earlier import ban. Oura is actively pursuing monetary damages and a permanent injunction to halt US sales of the disputed wearable.
Texas Federal Court
Oura filed its latest patent infringement complaint against rival smart ring maker Ultrahuman in a federal court located in Texas.
Ring Pro Target
The newly targeted device is Ultrahuman's Ring Pro, which was introduced following an earlier ban on the Ring Air model.
Disputed Patents and Manufacturing Details
The core of the current dispute revolves around two specific patents cited by Oura, designated as D804,471 and the newly minted 12,769,363. The latter patent was issued to Oura just two days prior to the filing and broadly covers internal smart ring arrangements including curved batteries, circuit boards, and sensors.
In addition to targeting Ultrahuman, Oura has named Texas-based electronics manufacturer SVTronics as a defendant. SVTronics manufactures the Ring Pro at a facility located in Plano, Texas, operating under the direction and control of the Bengaluru-based startup.
Patent 12,769,363
A newly issued patent covering smart ring designs, curved batteries, circuit boards, magnets, and integrated sensors.
SVTronics Defendant
Texas-based manufacturer SVTronics was named as a co-defendant for producing the Ring Pro domestically.
Prior Import Bans and Redesign Efforts
The ongoing rivalry between the two wearable tech companies intensified last year when an International Trade Commission ruling led to an import ban on Ultrahuman's original Ring Air product. That decision established that the older wearable infringed on several core Oura patents.
In response to the ban, Ultrahuman developed a modified Ring Pro designed to bypass the restricted intellectual property. The company secured a favorable review from US Customs and Border Protection earlier in the year, facilitating a brief return to American commerce.
Broader Market Landscape and Industry Rivalries
Oura's legal strategy extends well beyond its dispute with Ultrahuman, encompassing multiple competitors across the burgeoning smart ring sector. The company has previously initiated litigation or pursued enforcement actions against Samsung, RingConn, Circular, and Zepp Health.
While some rival manufacturers opted to settle by agreeing to licensing fees and royalty payments, others remain locked in active legal combat. Meanwhile, the global market continues to expand rapidly as consumer adoption for health-tracking wearables climbs.
Competitor Litigation
Oura has pursued patent enforcement actions against various market participants, including Samsung, RingConn, and Circular.
Licensing Agreements
Some competing firms have chosen to resolve patent disputes by entering into royalty agreements to sustain product sales.
Why It Matters
The ongoing legal battle between Oura and Ultrahuman highlights the fierce competitive pressures shaping the rapidly expanding smart ring market. As startups and established players race to capture consumer interest in health and fitness tracking, intellectual property has emerged as a critical barrier to entry. While regulatory bodies and customs agencies evaluate hardware modifications, aggressive patent litigation threatens to disrupt market access for newer entrants. Ultimately, these legal skirmishes will help define the boundaries of innovation and market dominance across the wearable technology landscape for years to come.
