Oura Sues Ultrahuman Again, Putting Its U.S. Smart Ring Expansion at Risk

12:45

The battle for control of the smart ring market has entered another legal phase, with Finnish wearable technology company Oura taking fresh action against Indian rival Ultrahuman in the United States. The new lawsuit challenges the technology used in Ultrahuman’s Ring Pro, raising questions about the product’s future in a market that remains central to the growth strategies of both companies.

Filed in a federal court in Texas on October 22, 2026, the complaint alleges that the Ring Pro infringes two Oura patents relating to the device’s design and internal components. Oura is seeking financial compensation and a permanent court order that would prevent Ultrahuman from selling the product in the United States.

The dispute comes only months after Ultrahuman secured clearance to bring its redesigned smart ring back to the American market following restrictions on imports of its earlier Ring Air model.

A New Legal Challenge After Ultrahuman’s Return

Ultrahuman introduced the Ring Pro in February 2026 as part of its strategy to rebuild its American business. The redesigned device received a favorable decision from U.S. Customs and Border Protection in March, allowing the company to resume its push into a market that plays a major role in its international operations.

Oura’s latest complaint, however, argues that the customs decision addressed an earlier patent dispute rather than the two intellectual property rights cited in the new case. One of those patents, covering aspects of a smart ring’s internal construction, was issued to Oura on October 20, just two days before the lawsuit was filed.

The legal action also names SVTronics, a Texas-based electronics manufacturer that Oura alleges produces the Ring Pro at a facility in Plano. According to the complaint, the manufacturing, importation and sale of the device infringe Oura’s patents.

These allegations have yet to be established by a final court judgment.

Ultrahuman Vows to Defend Its Product

Ultrahuman co-founder and chief executive Mohit Kumar has rejected the implications of the latest legal challenge, saying the company intends to contest the allegations through the appropriate judicial process.

Kumar also stressed that the lawsuit has not resulted in a court order preventing sales of the Ring Pro. The device remains available to American customers while the dispute proceeds.

The exchange underscores the uncertainty facing companies that seek to compete in a market where product design, sensor technology and compact electronic components are becoming increasingly important sources of differentiation.

For Ultrahuman, maintaining access to the United States is particularly significant. The company has invested in redesigning its hardware and rebuilding distribution after the earlier restrictions disrupted its commercial plans.

Oura’s Patent Strategy Extends Across the Industry

The confrontation is part of a broader series of intellectual property disputes involving Oura and competing smart ring manufacturers. The company has previously pursued legal action involving Ultrahuman and other players, including Samsung, RingConn, Circular and Zepp Health.

Some disputes have ended in commercial agreements, allowing competitors to continue selling their products in exchange for royalty payments. The latest case against Ultrahuman illustrates that legal exposure remains a major concern for businesses seeking to enter or expand within the category.

For technology companies, patent litigation can influence more than the outcome of a particular product launch. It can also affect manufacturing decisions, distribution arrangements, development costs and the timing of expansion into important markets.
