Oura files new lawsuit against Ultrahuman and Plano manufacturer

Consumers in the United States may face a pause in purchases of the Ultrahuman Ring Pro after Oura filed a new patent infringement lawsuit in a federal court in Texas. The complaint names Ultrahuman and SVTronics, a Plano, Texas facility that manufactures the device for the Indian company. Oura is seeking monetary damages and a court order to stop US sales of the ring, mirroring the remedy it obtained in a previous dispute.

The legal conflict began last year when the US International Trade Commission ruled that the Ultrahuman Ring Air violated several of Oura's patents. That decision resulted in a ban on US sales of the Ring Air, though the product continues to be sold in Europe and other regions. Following the loss, Ultrahuman redesigned its hardware for the US market to bypass the existing intellectual property claims.

Earlier this year, US Customs and Border Protection approved the redesigned Ring Pro after an independent review. The agency determined the new model did not infringe the specific patent under consideration at that time. However, Oura argues the modifications were not sufficient to clear its broader portfolio. The company states the new device still incorporates many of its patented innovations.

In a blog post, Oura challenged the rival's claims of compliance. "After it was found to be infringing Oura patents, Ultrahuman recently introduced a modified version of its ring, claiming its redesign no longer infringed our patents. That claim is false," the company wrote. Oura added that the Ring Pro "continues to infringe our intellectual property." The lawsuit cites two patents, one of which, Patent 12,769,363, was granted just two days before the complaint was filed.

Ultrahuman responded to the filing by stating it will contest the action. The company noted that the Ring Pro remains available for purchase in the US. A spokesperson for Ultrahuman said the redesign has already been through independent review in the United States. The spokesperson pointed out that Oura has now chosen to assert different patents, including one issued shortly before the lawsuit, and said the company would "defend our position vigorously."

This latest filing joins a series of legal engagements for Oura. The company recently announced a partnership with the US military that involves a Palantir hosting environment. It is also involved in a prolonged patent dispute with Samsung. In 2024, Samsung sued Oura preemptively over the Galaxy Ring, and Oura later filed its own suit against the tech giant. As of this summer, the two companies remain locked in that conflict.
