Oura targets SVTronics in new Texas suit to stop Ultrahuman Ring Pro sales

A new patent dispute has emerged between smart ring competitors Oura and Ultrahuman, with Oura filing a complaint in a Texas federal court against its rival. The lawsuit targets the Ring Pro, a device Ultrahuman launched after a previous model was blocked from the US market. Oura alleges that the new hardware infringes upon two distinct patents related to the ring's design and internal architecture.

The complaint, which Oura detailed in a blog post, seeks monetary damages and a preliminary injunction to halt US sales of the Ring Pro. One of the patents cited in the suit, number 12,769,363, was granted just two days before the legal action was initiated. This patent broadly covers smart ring designs featuring specific housing, battery, and component configurations.

This legal battle follows a 2025 victory for Oura, when the US International Trade Commission ruled that Ultrahuman’s Ring Air violated multiple patents. That ruling resulted in a ban on US sales for the older model, though it remains available in Europe and other regions. In response, Ultrahuman, an India-based company, modified the Ring Pro to bypass existing intellectual property protections. Earlier this year, US Customs and Border Protection approved the redesign, clearing it for entry.

Oura contends that the modifications were insufficient to avoid infringement. "That claim is false," the company wrote in its statement, asserting that the new ring continues to incorporate patented innovations. The suit also names SVTronics, a manufacturer in Plano, Texas, as a defendant. SVTronics builds the US version of the Ring Pro under Ultrahuman’s direction.

Ultrahuman has stated it will vigorously defend the product, which remains on sale in the United States. A spokesperson noted that the redesign underwent independent review and that Customs and Border Protection previously found no infringement. The spokesperson added that Oura is now asserting different patents, including one issued shortly before the lawsuit.

The filing adds to a period of intense legal activity for Oura. The company recently announced a partnership involving the US military and a Palantir hosting environment. It is also engaged in a prolonged patent dispute with Samsung, which began with a preemptive lawsuit by Samsung in 2024 regarding the Galaxy Ring. As of this summer, the two firms remain in litigation.

The Texas case represents the latest chapter in a competitive fight for dominance in the smart ring market, with both companies actively seeking to define the boundaries of their respective intellectual property holdings.
