Oura files fresh Texas suit to block Ultrahuman Ring Pro sales

Oura has filed a patent infringement lawsuit in a Texas federal court to stop the US sales of Ultrahuman’s Ring Pro. The complaint alleges that the device violates two specific patents held by the Finnish company, covering both the physical design and internal components of the smart ring.

The legal action targets the Ring Pro, a product Ultrahuman launched after the US International Trade Commission ruled against its earlier Ring Air model last year. That previous ruling resulted in a US sales ban for the Ring Air, though the device remains available in Europe and other international markets. Ultrahuman subsequently redesigned the ring to avoid the specific intellectual property claims that sank the Ring Air.

Oura argues that these modifications were insufficient. The company stated in a blog post that Ultrahuman’s claim that the redesign no longer infringed on their patents is false. Oura contends that the new device still incorporates many of its patented innovations and continues to infringe on its intellectual property rights.

The lawsuit names SVTronics as a co-defendant alongside Ultrahuman. SVTronics is the Plano, Texas-based manufacturer that builds the Ring Pro for the US market under Ultrahuman’s direction. TechCrunch reported that one of the patents cited in the suit, number 12,769,363, was granted just two days before Oura filed the complaint. This patent broadly covers a smart ring design featuring a specific housing, battery, and internal component configuration.

Ultrahuman, an India-based company, has said it will contest the action. A spokesperson told Engadget that the redesign has already undergone independent review in the United States. The spokesperson noted that US Customs and Border Protection previously concluded the Ring Pro did not infringe on the specific patent considered during that earlier proceeding. The company argues Oura is now asserting different patents, including the one issued just before the lawsuit was filed, and vows to defend its position vigorously.

This filing adds to a period of intense legal activity for Oura. The company recently announced a partnership with the US military that involves a Palantir hosting environment. It is also engaged in a prolonged patent dispute with Samsung, which began when Samsung preemptively sued Oura in 2024 over concerns regarding the Galaxy Ring. As of this summer, the two companies remain locked in that separate legal battle.
