Smart ring manufacturer Oura has filed a new lawsuit against Indian rival Ultrahuman, seeking to stop sales of its Ring Pro in the United States.
The legal action comes just months after Ultrahuman redesigned the device and secured clearance to return to the American market following an earlier import ban.

In a complaint filed in a federal court in Texas, Oura alleges that the Ring Pro infringes two of its patents covering the ring’s design and internal components.

The company is seeking financial compensation and a permanent injunction preventing Ultrahuman from selling the product in the United States.

Ultrahuman launched its redesigned Ring Pro in February, and US Customs and Border Protection issued a favourable ruling in March that allowed the company to resume sales.

The decision followed an import ban on the earlier Ring Air after Oura secured a patent infringement ruling from the International Trade Commission in August of the previous year.

Oura maintains that the customs decision addressed only the patent involved in the earlier dispute and did not resolve questions concerning the two patents cited in its latest lawsuit.

One of those patents, covering aspects of the ring’s internal components, was issued to Oura on October 20, just two days before the new complaint was filed.

Oura has also named Texas based electronics manufacturer SVTronics as a defendant, alleging that the company manufactures the Ring Pro at a facility in Plano, Texas, under Ultrahuman’s direction.

Both companies are accused of infringing Oura’s patents through the manufacture, importation and sale of the device.

Ultrahuman co founder and chief executive Mohit Kumar said the company would challenge the allegations through the appropriate legal process.
He maintained that no court order currently prevents Ring Pro sales and confirmed that the device remains available to American customers.

The dispute is part of a broader legal campaign by Oura to protect its intellectual property in the growing smart ring industry.

The company has pursued patent infringement claims against several competitors, including Samsung, RingConn, Circular and Zepp Health.

Some disputes have resulted in licensing agreements, with RingConn and Circular agreeing to pay royalties to Oura to continue selling their products.
Oura and Ultrahuman have been involved in patent disputes since 2023, when Oura first challenged the Ring Air, followed by a separate complaint before the International Trade Commission in 2024.

The latest lawsuit comes as competition in the smart ring market intensifies.

Research firm IDC expects global shipments to increase by 12.8 per cent this year to 4.9 million units and reach approximately 6.3 million by 2030.
Oura remains a major player, while Ultrahuman is seeking to expand its market presence after raising $70 million in September from investors including Qualcomm Ventures and Labcorp, giving the startup an estimated valuation of $365 million.

Oura has also reportedly shelved plans for a $2.2 billion initial public offering, citing market uncertainty, while continuing to introduce new health and fitness features.

Ultrahuman, meanwhile, is working with Qualcomm on a new smart ring designed to support more software directly on the device.
