Oura sues Ultrahuman over Ring Pro: what buyers should know

Oura has filed a new patent lawsuit against Ultrahuman, and this time the target is the Ring Pro, the smart ring Ultrahuman designed to get back into the US market after its older Ring Air was blocked from import. The complaint was filed on Thursday, October 22, 2026, in the US District Court for the Eastern District of Texas.

Oura is asking for damages and a permanent injunction, which would stop sales of the Ring Pro in the US if the court agrees. For now nothing has changed for shoppers: Ultrahuman says there is no court order against the Ring Pro and it is still on sale. Here is what the case is about, what it could mean for buyers and how the two rings compare on price.

What is Oura suing Ultrahuman for?

Oura says the Ring Pro infringes two of its US patents. One is design patent D804,471. The other, patent 12,769,363, was only issued on October 20, two days before the lawsuit was filed, according to TechCrunch. It covers a smart ring design that uses a curved battery, a circuit board, magnets and sensors inside the ring.

The suit also names SVTronics, a company that Oura says makes the Ring Pro for Ultrahuman in Plano, Texas. That detail matters because the earlier US ban covered imports of Ultrahuman's older ring, while the Ring Pro is made in the US.

In a post on its own blog, Oura pushed back on the idea that the Ring Pro is a clean redesign. "Ultrahuman's latest ring still incorporates many of Oura's patented innovations," the company wrote, adding that "changing a product to sidestep one patent does not give Ultrahuman the right to use the rest of Oura's innovations."

Why this is round two for Oura and Ultrahuman

The two companies have been fighting for more than a year. In 2025 the US International Trade Commission ruled that Ultrahuman's Ring Air infringed an Oura patent, and that led to a ban on importing the Ring Air into the US. The Ring Air is still sold in Europe and other markets, Engadget reports.

The ban hurt. TechCrunch reported in March that Ultrahuman lost up to $50 million in sales while it was locked out, and that its share of US smart ring sales fell from 24.6% in the second quarter of 2025 to low single digits, based on IDC data. Oura's US share rose to about 85% over the same period.

Ultrahuman's answer was the Ring Pro, which launched globally in late February 2026. In March, US Customs and Border Protection issued a ruling in Ultrahuman's favor, finding that the Ring Pro did not infringe the patent from the earlier case, and US pre-orders opened from $399.

What Ultrahuman says

Ultrahuman is fighting the new case. "Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," CEO Mohit Kumar said in a statement reported by TechCrunch. "We will address these claims through the appropriate legal process and will defend our position vigorously. There is no court order affecting Ring Pro, and it remains available to customers in the U.S."

Oura, for its part, says Ultrahuman "has a history of copying Oura's innovations, as demonstrated by the 2025 ITC ruling against the company."

Can you still buy the Ultrahuman Ring Pro in the US?

Yes. A lawsuit on its own does not stop sales. Oura would need the court to grant an injunction, either early in the case or after winning it, and patent cases like this one usually take months or years to reach that point. Until a judge orders otherwise, Ultrahuman can keep selling the Ring Pro.

Ultrahuman's US store currently lists the Ring Pro at $479 with its Pro charging case. The ring has a titanium body, up to 15 days of battery life (up to 45 days with the case), 100 meters of water resistance and sizes 5 to 14, and Ultrahuman does not charge a subscription for its app features.

If you already own a Ring Pro, nothing changes today. Even if Oura later wins an injunction, that kind of order normally targets future sales and imports rather than rings people have already bought, though how any order would affect app support and repairs would depend on its exact terms.

Ultrahuman Ring Pro vs Oura Ring 5: price

The price gap is part of why this fight matters to buyers. Oura's current ring, the Oura Ring 5, starts at $399 in Silver or Black and costs $499 in Gold, Deep Rose, Stealth and Brushed Silver, according to Oura's store. On top of that, Oura charges $5.99 a month for its membership.

Over a year, that membership adds about $72 to the cost of an Oura ring. The Ring Pro costs more upfront at $479 with its case, but Ultrahuman charges no ongoing fee.

Oura's patent fights go beyond Ultrahuman

Oura has used its patents against several rivals as smart rings have grown. According to TechCrunch, it has also gone after Samsung, RingConn, Circular and Zepp Health, and RingConn and Circular now pay Oura royalties. The dispute with Samsung, maker of the Galaxy Ring, is still going, Engadget reports.

The market these companies are fighting over is still small but growing. IDC expects about 4.9 million smart rings to ship worldwide in 2026, up 12.8% from last year, rising to around 6.3 million by 2030. The US made up about 2.6 million of the 4.4 million rings shipped in 2025.

What happens next

Ultrahuman will now respond to the complaint in court, and the case could take a long time to resolve. The bigger question is whether Oura asks for a preliminary injunction to stop Ring Pro sales while the case runs, which would be the fastest way for the lawsuit to affect shoppers. Neither company has said anything about that so far.

For buyers, the short version is simple: the Ring Pro is on sale in the US today, Ultrahuman says it will fight the claims, and nothing in this lawsuit affects rings people already own right now. We will update this story if the court issues any order.
