New Oura lawsuit threatens to once again disrupt smart ring market
Oct 23, 2026 — 12:38 PM ET
- Smart ring maker Oura is suing Ultrahuman again, seeking to have the Ring Pro removed from US shelves over alleged patent infringement.
- Ultrahuman’s co-founder says the company will respond to the claims and that the Ring Pro remains available in the US.
- Oura has previously sued Ultrahuman over the Ring Air, which led to its removal from US shelves last year.
Oura won a key patent dispute against rival smart ring maker Ultrahuman last year, forcing it to remove the Ring Air from US shelves. Ultrahuman has since released the Ring Pro in the US, featuring a redesigned heart-rate sensor and a two-week battery life. Now, in what can only be described as déjà vu, Oura is suing to pull the Ultrahuman Ring Pro from the US.
In a lawsuit filed in a Texas federal court, reports TechCrunch, Oura alleges that the Ring Pro infringes on two of its patents, specifically related to design and internal hardware, The company claims Ultrahuman’s smart ring violates patents D804,471 and 12,769,363, and seeks to ban its sale and recover damages.
“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,” an Oura spokesperson said in a statement. The lawsuit also names Plano, Texas-based electronics manufacturer SVTronics, alleging it is assembling and manufacturing the infringing product at Ultrahuman’s direction.
“Oura has now chosen to assert different patents, including one that issued just two days before this lawsuit was filed,” Ultrahuman co-founder and CEO Mohit Kumar told 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 US,” Kumar added.
The patent referenced by the Ultrahuman boss is number 12,769,363, which describes a smart ring and its accompanying internal hardware such as onboard sensors, magnets, the circuit board, and a curved battery. This particular patent was granted just a couple of days before Oura filed the lawsuit.
Ultrahuman isn’t the only smart ring brand that Oura has taken to court so far. Last year, the company sued Samsung and a few other smart ring makers, alleging multiple patent violations.
A year earlier, Samsung filed a preemptive lawsuit against Oura seeking a judgment that would effectively shield it from accusations of copyright infringement. However, a San Francisco District Court later dismissed this particular case.
It’s hard to say what the outcome of this fresh legal battle between the two smart ring manufacturers will be, but based on the Ultrahuman co-founder’s words, it’s far from over.
