Oura has filed a patent infringement lawsuit against smart ring competitor Ultrahuman in a Texas federal court. The legal action seeks to block U.S. sales of the Ultrahuman Ring Pro, which is manufactured locally in Plano, Texas.
Why it matters
This litigation intensifies the competitive pressures within the expanding smart ring market as Oura moves to enforce its patent portfolio against newer entrants. Startups operating in hardware sectors face increasing risks of costly intellectual property disputes that can disrupt supply chains and market entry.
Ultrahuman recently raised $70 million at a $365 million valuation, competing in a sector expecting 4.9 million unit shipments this year. Oura previously established a legal baseline by securing an import ban on other competitors and forcing royalty agreements with RingConn and Circular.
The players
Oura
A health technology company that manufactures smart rings and manages a significant patent portfolio.
Ultrahuman
A health-tech startup that produces the Ring Pro and recently raised $70 million in funding.
SVTronics
An electronics manufacturing services provider that operates a facility in Plano, Texas.
The details
The lawsuit alleges infringement of two specific patents, including one issued on October 20, 2026, which covers design and internal components. Oura also named SVTronics as a co-defendant, targeting the manufacturer responsible for producing the Ultrahuman Ring Pro in Plano, Texas. This move follows a history of patent disputes between the companies dating back to 2023, despite a March 2026 U.S. Customs ruling that initially favored Ultrahuman.
Timeline
2023: Oura and Ultrahuman began patent disputes.
August 2025: ITC issued a patent ruling leading to an import ban.
February 2026: Ultrahuman launched the redesigned Ring Pro.
March 2026: U.S. Customs ruled in favor of Ultrahuman.
October 22, 2026: Oura filed the current patent infringement lawsuit.
Market Landscape
This litigation follows the pattern set by Oura's 2025 successful enforcement actions that secured import bans and royalty deals. It reflects the broader consolidation of the smart ring sector, where incumbents increasingly use intellectual property litigation to protect market share against new entrants.
Hardware founders should note that local manufacturing does not insulate a product from federal patent injunctions if the underlying design is contested. Operators should review their IP documentation and supply chain vendor agreements to understand their exposure to potential patent litigation.
The takeaway
Intellectual property strategy remains a critical barrier to entry in the hardware sector as the market prepares for an projected 6.3 million units sold by 2030. Operators should audit the licensing status of all proprietary internal components and design elements in their product pipeline.
