Oura sues Ultrahuman over Ring Pro, seeks to stop US sales
Oura has sued Indian smart-ring maker Ultrahuman in a federal court in Texas over Ultrahuman’s Ring Pro.
Oura says the ring infringes two patents covering its design and internal components, and is seeking damages and a permanent stop to US sales.
The lawsuit puts Ultrahuman’s US return at risk after its earlier Ring Air was barred from the market following a patent ruling in Oura’s favor.
Ultrahuman redesigned the Ring Pro, and US Customs and Border Protection cleared it for entry earlier this year.
Oura says that clearance did not cover the two patents in this case, including one issued just two days before the lawsuit was filed.
Ultrahuman says the Ring Pro remains on sale in the US and that it will defend itself through the legal process.
The court case will determine whether sales can continue; no outcome is stated.

What people are saying
Ultrahuman has a history of copying Oura’s innovations, as demonstrated by the 2025 ITC ruling against the company.
Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura’s patents, seeking instead to capitalize on our innovation and the market leadership we have built.
Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed.
We will address these claims through the appropriate legal process and will defend our position vigorously.
