Oura sues Ultrahuman again to block Ring Pro US sales

Oura, the Finnish maker of the best-known health-tracking smart ring, sued its Indian rival Ultrahuman again on Thursday, October 22, 2026. The new suit says Ultrahuman's Ring Pro infringes two Oura patents, and it asks a Texas federal court to stop US sales of the ring. It is the third legal round between the two companies, and it targets the very device Ultrahuman built to get back into the US market.

A smart ring is a finger-worn sensor that tracks sleep, heart rate and temperature, then syncs the data to a phone app. The category is small but growing. TechCrunch, citing the research firm IDC, reports smart-ring shipments will grow 12.8% this year to 4.9 million units, reaching about 6.3 million by 2030.

What Oura claims in the new lawsuit

Oura filed the complaint in the US District Court for the Eastern District of Texas, according to Oura's own announcement as quoted by Gadgets & Wearables. It names two defendants: Ultrahuman and SVTronics, a Texas electronics maker. Oura alleges SVTronics builds the Ring Pro at a facility in Plano, Texas, under Ultrahuman's direction.

The suit rests on two patents.

Patent	What it covers	Issued
D804,471	A design patent on the look of a wearable computing device	Not stated in the reports
12,769,363	A ring with a curved battery, circuit board, charging magnets, and optical, temperature and movement sensors	October 20, 2026

The second patent was granted just two days before Oura sued. The outlets differ slightly on the first. TechCrunch describes both patents as covering the ring's design and internal parts, while Gadgets & Wearables calls D804,471 a design-only patent.

Oura asks for money damages and a permanent injunction. That is a court order that would bar Ultrahuman from selling the Ring Pro in the US. An Oura spokesperson told TechCrunch that "Ultrahuman has a history of copying Oura's innovations," pointing to a 2025 trade ruling.

How the dispute got here

The fight is three years old. Each step below comes from TechCrunch, Engadget and Gadgets & Wearables.

Date	Event
2023	Oura sues Ultrahuman over the Ring Air
2024	Oura files a separate case at the US International Trade Commission (ITC)
August 2025	The ITC rules for Oura, and a US import ban on the Ring Air follows
February 2026	Ultrahuman unveils the redesigned Ring Pro
March 2026	US Customs and Border Protection rules in Ultrahuman's favor on the Ring Pro
October 22, 2026	Oura files the new suit in Texas

The ITC is a federal agency that can block imports of products that infringe US patents. The Ring Air is still sold in Europe and other markets, according to Engadget. A third ring maker, RingConn, settled with Oura and signed a multi-year licensing deal, Gadgets & Wearables reports.

The customs ruling is the crux. Ultrahuman says customs found the Ring Pro "did not infringe the Oura patent considered in that proceeding." Oura's argument is that the ruling covered only that earlier patent, not the two in the new case. In a blog post quoted by Engadget, Oura said "Ultrahuman's latest ring still incorporates many of Oura's patented innovations."

What Ultrahuman says

Ultrahuman says it will fight. "We will address these claims through the appropriate legal process and will defend our position vigorously," the company said. TechCrunch attributes that line to co-founder and CEO Mohit Kumar, while Engadget credits a spokesperson.

The company also says nothing has changed for buyers yet. "There is no court order affecting Ring Pro, and it remains available to customers in the U.S.," it told TechCrunch. In a statement to Gadgets & Wearables, it added that the new claims "have not been adjudicated by a court."

What this means for developers

For anyone who builds or buys health wearables, the practical picture is simple for now. The Ring Pro is on sale in the US, and no court has ruled on the new claims. A permanent injunction would need a ruling first, so nothing changes today.

Three points are worth acting on:

• A customs clearance is narrow. It answered one question about one patent. Hardware teams relying on a similar ruling should map which patents it did not cover.
• New patents can appear mid-fight. Patent 12,769,363 issued two days before the suit. A rival's pending applications are a live risk, not old history, so track them.
• Building in the US is not a shield. The ITC route targets imports. By naming the Plano manufacturer, Oura is also going after a ring made inside the country, through a regular court.

Teams that bought Ring Pro devices for staff wellness programs should watch for an injunction request. That would be the first sign US availability could change.
