Oura has filed a patent infringement lawsuit in federal court in Texas against competitor Ultrahuman. The complaint alleges that Ultrahuman's Ring Pro device infringes on design and internal component patents.

Why it matters

Oura claims that Ultrahuman continued to infringe on its intellectual property even after the design of the Ring Pro was updated. The move follows a period of intense legal pressure from Oura, which has previously secured royalty agreements from other market competitors.

Ultrahuman holds a $365 million valuation following a $70 million funding round in September 2026. Meanwhile, global smart ring shipments are expected to grow by 12.8% this year, reaching a total of 4.9 million units.

The players

Oura

A developer of wearable smart ring technology that has been aggressive in defending its intellectual property through legal channels.

Ultrahuman

A startup based in Bengaluru that produces health-tracking wearable devices and competes directly in the smart ring market.

SVTronics

A manufacturing firm based in Plano, Texas, that handles the production of hardware components for various tech companies.

The details

The lawsuit names SVTronics, which manufactures the Ring Pro in Plano, Texas, as a co-defendant. Oura is specifically alleging that the device violates patent 12,769,363, which was issued on October 20, 2026, as well as patent D804,471.

Timeline

  1. Oura and Ultrahuman began patent disputes in 2023.

  2. The ITC issued a patent ruling leading to an import ban in August 2025.

  3. Ultrahuman launched the redesigned Ring Pro in February 2026.

  4. U.S. Customs ruled in favor of Ultrahuman in March 2026.

  5. Oura filed the patent infringement lawsuit on October 22, 2026.

Market Landscape

This litigation highlights the increasingly litigious nature of the smart ring market as established players seek to protect their design patents. The sector is currently seeing a consolidation of market share, with Oura leveraging legal injunctions to force competitors to enter royalty agreements.

Customers who own or plan to purchase a Ring Pro may face potential supply interruptions if the requested permanent injunction is granted by the court. This legal battle could ultimately affect the retail availability and pricing of smart ring products within the United States market.

The takeaway

Intellectual property disputes remain a primary strategic hurdle for emerging hardware companies in the high-growth wearables sector. Consumers should remain aware that legal outcomes regarding patent infringement can directly impact the long-term support and availability of niche tech products.
