Oura has filed a patent infringement lawsuit in federal court against Ultrahuman and its manufacturing partner, SVTronics. The complaint seeks a permanent injunction to block U.S. sales of the Ring Pro, alleging the device violates patents regarding internal hardware and design.
Why it matters
The lawsuit escalates a long-standing intellectual property conflict in the wearable technology sector as market competition intensifies. It serves as a test of Oura's ability to enforce its design and component patents against emerging rivals following previous legal battles.
The lawsuit targets patent D804,471 and patent 12,769,363, which was issued on October 20, 2026. Oura contends these protections cover the specific internal components and design elements used in the Ultrahuman Ring Pro.
The players
Oura
A health-tracking technology company known for its smart rings and integrated health-monitoring software.
Ultrahuman
A venture-backed startup developing wearable wellness devices and metabolic health tracking software.
SVTronics
A contract manufacturing services provider based in Plano, Texas, specializing in electronic assembly.
The details
Oura claims that despite previous redesigns, the Ultrahuman Ring Pro continues to infringe on its proprietary technology. The complaint focuses on patents covering the integration of sensors and structural design, arguing that SVTronics, which manufactures the rings in Plano, Texas, is central to the allegedly infringing production process.
Timeline
2023: Oura and Ultrahuman began patent disputes.
August 2025: ITC issued 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 patent infringement lawsuit.
The Tech Race
This litigation follows the precedent set by the August 2025 ITC patent ruling, which established the legal framework for import enforcement in the smart ring sector. Oura continues to aggressively defend its intellectual property as global market volume is projected to grow to 6.3 million units by 2030.
If the federal court grants the requested injunction, the availability of the Ultrahuman Ring Pro for U.S. customers could change. The outcome remains subject to the judicial process, and no immediate changes to existing device functionality or retail availability have been announced.
The takeaway
This case highlights the volatility of the smart ring market as established leaders seek to maintain dominance through litigation. Watch for the court's upcoming response to the motion for an injunction, which will dictate whether the Ring Pro remains in the U.S. market.
