Oura sues Ultrahuman again over Ring PRO patents
Oura has filed another US patent lawsuit against Ultrahuman, but the Ring PRO remains on sale while the latest case moves through court.
Oura has filed another patent lawsuit against Ultrahuman, asking a US federal court to block sales of the Ring PRO in America. The case arrives after Ultrahuman’s redesigned smart ring returned to the US market following an earlier dispute.12
What Oura is claiming
According to the complaint reported by TechCrunch, Oura says the Ring PRO infringes two patents covering the ring’s design and internal hardware, including its sensors, battery and circuit board. Oura is seeking damages and a permanent injunction. One of the patents, 12,769,363, was issued just two days before the new lawsuit was filed.12
The complaint also names Plano, Texas-based electronics manufacturer SVTronics. Oura alleges that SVTronics assembles and manufactures the infringing product under Ultrahuman’s direction. Those are allegations in a fresh lawsuit, not findings by a court.1
Ultrahuman says the Ring PRO remains available
Ultrahuman co-founder and CEO Mohit Kumar told TechCrunch that the company will defend itself and that the new case concerns different patents from the earlier Ring Air dispute. Kumar said there is no court order affecting the Ring PRO and that it remains available to US customers.2
That response is important because the earlier legal fight did affect product availability. Oura’s previous case helped force the Ring Air from US shelves, while Ultrahuman says a redesigned Ring PRO later received a favourable US Customs and Border Protection ruling. The latest complaint is an attempt to reopen that commercial pressure, but it has not yet produced a sales ban.12
Why the case matters
The dispute is the latest chapter in a wider fight over smart-ring design and technology. Oura has also pursued claims involving other major ring makers, while rivals are trying to compete on sensors, health software and subscription-free features. A successful injunction could make it harder for smaller companies to enter the US market; a failed claim would give them more room to challenge Oura’s position.
For British and European readers, the immediate US sales question is less important than the precedent. The Ring PRO remains on sale while the case moves through court, and the eventual outcome may depend on whether the two patents survive scrutiny and whether the companies reach a settlement.12
Our opinion
This is news because the lawsuit could change the availability of a major rival product, not because either company has won the argument. Oura’s earlier legal victory provides context, but the fresh patents and Ultrahuman’s unchanged sales position mean the outcome is unresolved. The sensible line is to watch for a court order or settlement rather than assume another filing will immediately remove the Ring PRO from shops.
