Oura Targets Plano Factory in Texas Suit Against Ultrahuman
The Finnish company alleges the redesigned Ring Pro violates two patents, including one granted just 48 hours before the complaint was filed.
By Amina Kaminski ·
Oura has filed a new patent infringement lawsuit in federal court in Texas, seeking to halt US sales of Ultrahuman’s Ring Pro. The complaint names Ultrahuman and SVTronics, the Plano-based manufacturer that builds the device for the US market.
This legal action follows a year of conflict between the two smart ring makers. Last year, the US International Trade Commission ruled that Ultrahuman’s Ring Air violated several Oura patents. That decision resulted in a sales ban for the Ring Air in the United States, though the product remains available in Europe and other regions.
Ultrahuman subsequently redesigned its product to create the Ring Pro. The company aimed to modify the device to avoid Oura’s intellectual property claims in the American market. Earlier this year, US Customs and Border Protection approved the redesign after an independent review, concluding that the Ring Pro did not infringe the specific patent considered during that earlier proceeding.
Oura now argues that the modifications were insufficient to clear its broader portfolio of patents. The company claims the new ring still incorporates many of its patented innovations. According to a blog post, Oura stated that the claim of a non-infringing redesign is false and that the device continues to infringe its intellectual property.
The suit cites two specific patents. One of these, Patent 12,769,363, was granted only two days before the complaint was lodged. This patent covers a smart ring design featuring a specific housing, battery, and internal components. Oura is requesting monetary damages and a court order to stop Ultrahuman from selling the Ring Pro in the US, mirroring the remedy it secured for the Ring Air.
Ultrahuman has responded by saying it will contest the action. A company spokesperson noted that Oura has chosen to assert different patents in this new filing. The spokesperson added that the company intends to defend its position vigorously while the Ring Pro remains on sale in the United States.
This case joins a series of legal battles for Oura. The company is currently in a prolonged patent dispute with Samsung, which began in 2024 when Samsung preemptively sued Oura over the Galaxy Ring. Additionally, Oura recently announced a partnership with the US military that utilizes a Palantir hosting environment.
