The Oura Ultrahuman lawsuit is back. Oura has filed a new patent infringement suit against Ultrahuman in a Texas federal court, seeking to block US sales of the Ultrahuman Ring Pro. The move follows an earlier Oura win that led to a US sales block on Ultrahuman’s Ring Air.
Oura says the Ring Pro violates two of its patents covering design and internal components. The company is seeking monetary damages and wants Ultrahuman stopped from selling its latest smart ring in the US market.
What Oura Claims About the Ring Pro
Oura’s position is direct. The company says Ultrahuman introduced a modified ring after being found to infringe Oura patents, claiming the redesign no longer infringed. Oura rejects that claim outright.
In its post, Oura said Ultrahuman’s latest ring “still incorporates many of Oura’s patented innovations and continues to infringe our intellectual property.”
The two patents at issue include one approved just two days before Oura filed the lawsuit. That patent (12,769,363) appears to broadly cover a smart ring design with a housing, a battery, and specific internal components.
The Ring Air Ban and the Ring Pro Redesign
India-based Ultrahuman’s Ring Air was banned for sale in the US after the International Trade Commission ruled it violated several Oura patents. The Ring Air remains on sale in Europe and other markets.
Ultrahuman then redesigned its Ring Pro to avoid violating Oura’s intellectual property in America. The company received approval from US Customs and Border Protection earlier this year.
The Ring Pro is manufactured at a plant in Plano, Texas, for the US market by a company called SVTronics under Ultrahuman’s direction. Oura also named SVTronics as a defendant in the lawsuit.
Ultrahuman Pledges to Fight the Claims
Ultrahuman said it will fight Oura’s legal action and confirmed the Ring Pro remains on sale in the US. A spokesperson told media that the Ring Pro redesign had already been through independent review in the United States.
Following an earlier patent proceeding, US Customs and Border Protection determined that the Ring Pro did not infringe the Oura patent considered in that proceeding, the spokesperson said. Ultrahuman also noted that Oura has now chosen to assert different patents, including one that issued just two days before the lawsuit was filed.
Ultrahuman said it will address the claims through the appropriate legal process and will defend its position vigorously.
A Wider Patent Battle Across Smart Rings
This is not an isolated dispute. Last year, Oura successfully sued Ultrahuman and got a court to block US sales of the Ring Air. The Oura Ultrahuman lawsuit is now in its second round.
Oura has also drawn attention recently after announcing a partnership with the US military that included the use of a Palantir hosting environment.
Separately, Samsung pre-emptively sued Oura in 2024 over concerns that Oura planned to sue Samsung over its Galaxy Ring launch. Oura subsequently did sue Samsung, and as of this summer, the companies remain locked in a pitched legal battle over patents.
What the New Filing Could Mean for Buyers
For now, the Ring Pro remains available in the US while the case proceeds. Two questions matter most: whether the court grants Oura’s request to block sales, and how the newly issued patent holds up under scrutiny.
Ultrahuman’s argument leans on the earlier Customs and Border Protection review, which covered a different patent than the ones now asserted. Oura’s case leans on a patent granted days before filing, which Ultrahuman has signaled it will challenge through the legal process.
The Oura Ultrahuman lawsuit adds another chapter to the smart ring patent wars. Oura wants the Ring Pro off the US market and monetary damages. Ultrahuman says its redesign was already cleared in an earlier proceeding and vows to defend its position. With Samsung also entangled in litigation with Oura, the legal fights shaping the smart ring industry show no sign of cooling.
