Oura sues Ultrahuman again, aiming to pull the Ring Pro from US stores

Ultrahuman redesigned its smart ring to get back into the United States after losing a patent fight to Oura. Seven months after customs officials cleared that new ring, Oura is back in court to get it pulled again.

In a complaint filed on Oct. 22 in the US District Court for the Eastern District of Texas, Oura claims Ultrahuman's Ring Pro infringes two of its patents, according to TechCrunch. It is asking for money damages and a permanent injunction that would stop Ultrahuman from selling the ring in the US. The suit also names SVTronics, a manufacturer that Oura says builds the Ring Pro at a plant in Plano, Texas, under Ultrahuman's direction.

Why the old clearance doesn't settle it

The Ring Pro was Ultrahuman's answer to the last round. Oura won a case at the US International Trade Commission in August 2025, which led to an import ban on Ultrahuman's Ring Air. Ultrahuman launched the redesigned Ring Pro in February, and US Customs and Border Protection ruled in March that it could come into the country.

Oura's argument is that the customs ruling only covered the patent from that earlier dispute. The new complaint cites two others: design patent D804,471, and utility patent 12,769,363, which describes a ring with a curved battery, a circuit board, charging magnets and sensors. The second one was issued on Oct. 20, two days before Oura filed.

"Ultrahuman has a history of copying Oura's innovations, as demonstrated by the 2025 ITC ruling against the company," an Oura spokesperson told TechCrunch. "Ultrahuman introduced a redesigned ring but failed to address continued infringement of Oura's patents."

Ultrahuman CEO Mohit Kumar pointed at the timing. "Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," he said. "There is no court order affecting Ring Pro, and it remains available to customers in the U.S." In a statement to Gadgets & Wearables, the company added that there is "no change to our current retail plans or operations."

Oura's long list of patent fights

The two companies have been fighting since 2023, and Ultrahuman isn't Oura's only target. Oura has also gone after Samsung, RingConn, Circular and Zepp Health. Some of those cases ended in deals: RingConn and Circular now pay Oura royalties to keep selling their rings.

The category is still growing. IDC expects smart ring shipments to rise 12.8% this year to 4.9 million units worldwide, according to TechCrunch. Oura is still one of its leading players: it passed 6 million subscribers, The Wall Street Journal reported on Oct. 22, a few weeks after the company shelved a $2.2 billion IPO, citing uncertainty in the market. Ultrahuman, for its part, raised $70 million in September from investors including Qualcomm Ventures and Labcorp, at a valuation of about $365 million, and is working with Qualcomm on a new ring.

What it means if you want a Ring Pro

Nothing changes yet. A complaint is not a ruling, no injunction has been issued, and the Ring Pro is still on sale in the US. The case could take months, and the earlier fight between these two companies ended with an import ban, so it's worth keeping in mind if you're choosing between smart rings this holiday season.
