Oura Sues Ultrahuman Again Over Ring Pro Patents

Oura Sues Ultrahuman Over Smart Ring Patents Following Ring Pro Launch

Oura filed a new patent infringement lawsuit against rival wearable maker Ultrahuman on October 22, 2026, targeting the internal components and physical architecture of the newly introduced Ultrahuman Ring Pro. According to a report by TechCrunch, the legal action arrives just days after the U.S. Patent and Trademark Office granted Oura a specific patent covering internal hardware designs.

The Tech TL;DR:

• Oura’s lawsuit targets internal hardware components of the Ultrahuman Ring Pro, including curved batteries, circuit boards, magnets, and sensors.
• The legal challenge was filed on October 22, 2026, exactly two days after Oura received U.S. Patent 12,769,363.
• Despite the ongoing litigation and past import restrictions in the United States, Ultrahuman maintains that sales of the Ring Pro remain active for American consumers.

Patent Disputes Over Internal Components and Circuitry

The legal filing centers directly on the physical engineering of the smart ring hardware. Oura asserts that the Ultrahuman Ring Pro infringes upon design and internal component patents related to its curved battery, circuit board, magnets, and sensors. An Oura spokesperson stated to TechCrunch that “Ultrahuman has a history of copying Oura’s innovations, as demonstrated by the 2025 ITC ruling against the company,” adding that Ultrahuman “introduced a redesigned ring but failed to address continued infringement of Oura’s patents.” Oura is currently seeking monetary damages.

The timing of the complaint closely follows intellectual property office activity. Oura was granted internal-component patent 12,769,363 on October 20, 2026, and initiated the court proceedings forty-eight hours later. Responding to the filing, Ultrahuman co-founder and CEO Mohit Kumar told TechCrunch, “Oura has now chosen to assert different patents, including one that was issued just two days before this lawsuit was filed.” Kumar confirmed that current court orders have not blocked availability, allowing the Ring Pro to remain accessible to U.S. buyers.

Ultrahuman Sues Oura over Smart Ring Patents

This filing escalates an ongoing, multi-year intellectual property battle between the two companies. In 2025, Ultrahuman initiated legal action against Oura, accusing the company’s Ring 4 of copying patented smart ring technology focused on sleep tracking, circadian tools, and women’s health features. While Oura operates on a subscription-heavy model for software features, Ultrahuman distributes its tools without a paywall via its PowerPlugs platform.

Beyond the courtroom battles, Ultrahuman expanded its software capabilities in October 2026 by rolling out a Heart Scan feature designed to deliver a sixty-second snapshot of heart condition metrics. The company also integrated with HealthEx to connect user smart ring data directly with official medical records.
