Smart Ring Lawsuit: Oura Sues Plano Manufacturer to Halt Ring Pro Sales
The Finnish wearable company alleges that Ultrahuman's redesigned ring violates two patents, including one granted days before the filing.
By Kavya Kapoor ·
Oura has filed a lawsuit in a Texas federal court seeking to stop the US sales of Ultrahuman's Ring Pro smart wearable. The complaint names SVTronics, a manufacturing plant in Plano, Texas, as a co-defendant. The company argues that the device infringes on two specific Oura patents related to design and internal components.
The legal action follows a previous victory for Oura. Last year, the US International Trade Commission ruled that the original Ring Air violated several patents. That decision led to a ban on US sales of the older model, though it remains available in Europe and other regions. Ultrahuman subsequently redesigned its product to avoid those specific intellectual property claims. The US Customs and Border Protection agency approved the redesign for entry into the US market earlier this year.
Oura disputes the sufficiency of those changes. The company states that the new ring still incorporates many of its patented innovations. "After it was found to be infringing Oura patents, Ultrahuman recently introduced a modified version of its ring, claiming its redesign no longer infringed our patents. That claim is false," Oura wrote in a blog post. The complaint asserts that the device continues to violate their intellectual property rights.
One detail in the filing drew immediate attention. Patent 12,769,363, which covers a smart ring housing with a battery and specific internal parts, was granted only two days before the lawsuit was lodged. Oura is requesting monetary damages and an injunction to block further US sales. The company is based in Finland, while Ultrahuman is headquartered in India.
Ultrahuman plans to contest the new claims. A spokesperson told Engadget that the Ring Pro is still on sale in the US. The company noted that the redesign had already undergone independent review by US Customs and Border Protection. "We have now chosen to assert different patents, including one that issued just two days before this lawsuit was filed," the spokesperson said, adding that Ultrahuman will defend its position vigorously.
This case arrives during a period of intense legal activity for Oura. The company recently announced a partnership with the US military involving a Palantir hosting environment. It is also engaged in a prolonged patent dispute with Samsung. Samsung initially sued Oura in 2024 over concerns regarding the Galaxy Ring. Oura later filed its own suit against Samsung, and the two companies remained in that dispute as of this summer.
