Oura sues Ultrahuman again over redesigned Ring Pro, seeks U.S. sales ban

Lawsuit targets redesigned Ring Pro and manufacturer

Oura has filed a patent infringement lawsuit in a federal court in Texas against Ultrahuman and its manufacturing partner, SVTronics, alleging that Ultrahuman’s redesigned Ring Pro infringes two of its patents. The lawsuit seeks monetary damages and a permanent injunction to prevent Ultrahuman from selling the Ring Pro in the U.S.

The patents in question involve the ring’s design and internal components, including its battery and sensors. One of the patents, 12,769,363, was granted to Oura on October 20, 2026—just two days before the lawsuit was filed. The patent covers a smart ring design with a housing, curved battery, circuit board, magnets, and sensors.

SVTronics, which manufactures the Ring Pro at its facility in Plano, Texas, is also named as a defendant in the lawsuit. Oura alleges that SVTronics produces the device under Ultrahuman’s direction and control.

Regulatory ruling allowed Ring Pro’s U.S. return

The lawsuit follows a U.S. Customs and Border Protection ruling in March 2026 that permitted Ultrahuman’s redesigned Ring Pro to re-enter the U.S. market. The ruling, however, only covered the patent involved in an earlier dispute, not the two patents cited in Oura’s latest lawsuit.

Ultrahuman’s earlier product, the Ring Air, was banned from U.S. sales after the U.S. International Trade Commission ruled it violated Oura’s patents. The Ring Air remains available in Europe and other markets outside the U.S.

Legal battles escalate in smart ring market

This lawsuit marks the latest in a series of legal disputes between Oura and Ultrahuman, which began in 2023. Oura has also been involved in patent litigation with Samsung over its Galaxy Ring, with both companies suing each other in 2024.

Ultrahuman, backed by investors including Qualcomm Ventures and Labcorp, raised $70 million in September 2026, valuing the company at approximately $365 million. Oura, meanwhile, postponed its $2.2 billion IPO earlier this year, citing market uncertainty.

Ultrahuman’s response

Ultrahuman’s co-founder and CEO, Mohit Kumar, stated that the company will vigorously defend its position in the legal process. The Ring Pro remains on sale in the U.S. despite the lawsuit.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

This lawsuit underscores the high stakes in the smart ring market, where intellectual property disputes can disrupt sales, force product redesigns, and shape competitive dynamics. For founders and operators, the case highlights the risks of entering markets with established incumbents—particularly in the U.S., where patent litigation is a common tool to block rivals. Ultrahuman’s ability to secure a Customs ruling in its favor earlier this year demonstrates that regulatory victories can be temporary if new patents emerge. The outcome could set a precedent for how broadly smart ring patents are enforced, affecting not just Oura and Ultrahuman but other players like Samsung, RingConn, and Circular.

Key takeaways

• U.S. patent litigation is a significant risk for wearable startups targeting the American market, even for products that have received regulatory approvals.
• Manufacturing partnerships, such as Ultrahuman’s with SVTronics, can become legal liabilities if the final product is alleged to infringe patents.
• The timing of Oura’s patent grants—one issued just days before the lawsuit—suggests a strategic approach to bolstering legal claims.
• For Indian startups expanding globally, this case illustrates the challenges of navigating intellectual property landscapes in key markets like the U.S.
