One of the two patents in Oura's new lawsuit was issued on October 20. The complaint was filed two days later. That timing tells you how seriously Oura is taking the Ultrahuman Ring Pro.
What happened
Oura has sued Ultrahuman again in a federal court in Texas. It wants to stop US sales of the Ultrahuman Ring Pro. The suit claims the ring infringes two patents, a design patent (D804,471) and a utility patent (12,769,363). According to the reports, the utility patent covers a ring with a curved battery, a circuit board, magnets and sensors. Oura is asking for monetary damages and a permanent injunction. It also named SVTronics as a defendant. Oura says SVTronics builds the Ring Pro in Plano, Texas, under Ultrahuman's direction.
Why this is a rerun
Ultrahuman's earlier Ring Air was barred from US import after Oura won an International Trade Commission ruling in August 2025. The company then redesigned the ring. The Ultrahuman Ring Pro launched in February, and US Customs and Border Protection ruled in its favor in March. That ruling is what let Ultrahuman back into the American market.
Oura says the customs decision only covered the patent from the earlier fight, not these two. Ultrahuman says the redesign has already been through independent review. Its CEO, Mohit Kumar, told TechCrunch there is no court order affecting the Ring Pro and that it remains available in the US. Oura's own statement accuses Ultrahuman of a history of copying. Neither side's claims have been tested in a final ruling.
This also isn't Oura's first target. The suit follows earlier patent disputes with Samsung and RingConn.
Who should care
If you own a Ring Pro, nothing changes today. Nobody has ordered anything. Patent cases are slow, and the first fight ran from 2023 to a ban in 2025. A sales block is unlikely to arrive next week.
If you're about to buy one, the risk is different. I couldn't confirm a US price or any refund or support commitments in the sources I found, so I won't guess. The practical worry is a possible injunction later. That could leave you with a ring whose future sales, accessories and replacements are uncertain. That is speculation on my part, not something the reports say. I'd also note that the earlier redesign did clear customs, which is a point in Ultrahuman's favor.
My take: this is mostly a fight between two companies, and the lawsuit alone is no reason to panic. But if you were on the fence between an Oura ring and the Ultrahuman Ring Pro, the lawsuit gives you a small, real reason to lean toward the safer option. The cheaper ring isn't much of a deal if it ends up stranded.
What to do
Buy from a retailer with a generous return window, and keep your receipt. Watch the Eastern District of Texas docket for any motion seeking a preliminary injunction. That would be the first sign this is moving faster than the headlines suggest.
