Oura Sues Ultrahuman Again Over the Ring Pro

The smart ring patent fight is back. Oura has filed a fresh lawsuit against Ultrahuman, the Bengaluru-based ring maker, and this time it's going after the Ring Pro, the redesigned model that let Ultrahuman return to the US after an import ban.

What happened

As TechCrunch reported, Oura filed the complaint in a federal court in Texas on 22 October 2026. It says the Ultrahuman Ring Pro infringes two Oura patents: a design patent, D804,471, and utility patent 12,769,363, which covers a ring design with internal parts like a curved battery, circuit board, magnets and sensors. That second patent was only granted on 20 October, two days before the suit.

Oura wants damages and a permanent injunction that would stop Ring Pro sales. It has also named SVTronics, a Texas electronics manufacturer that it says builds the Ring Pro at a plant in Plano. Engadget also covered the filing.

Ultrahuman CEO Mohit Kumar told TechCrunch the company will fight the claims, and stressed that no court order affects the Ring Pro, which is still on sale to US customers.

Why it matters

This is round two of a long fight. Oura won a ruling at the US International Trade Commission last year that led to an import ban on Ultrahuman's Ring Air. Ultrahuman then launched the redesigned Ring Pro in February, and US Customs ruled in March that it could be imported. Oura argues that ruling only dealt with the old patent, not the two it's citing now.

Oura has taken a similar approach with other rivals. It has gone after Samsung, RingConn, Circular and Zepp Health, and some of those cases ended with the competitor paying royalties to keep selling. I don't love where that leaves buyers. When the rival rings either vanish from shelves or quietly cost more to cover a licence fee, you end up with fewer options and less reason for anyone to cut prices. Smart rings are still a pretty small category, so losing even one serious competitor in the US is a big deal.

What to do

• If you already own an Ultrahuman ring, nothing changes today. A lawsuit isn't a ban, and the ring and app keep working.
• Planning to buy one in the US? It's still on sale, but this could drag on for a while, so I'd check the return window and warranty before paying.
• Elsewhere, including India where Ultrahuman is based, this filing doesn't touch sales. A US loss could still change the company's plans, though.

I'll keep an eye on this one. If wearables go on sale in the meantime, they'll show up in my daily tech deals round-up.
