Oura has sued rival Ultrahuman again, asking a federal court in Texas to block US sales of the Ultrahuman Ring Pro. The complaint, filed Thursday, alleges the redesigned smart ring infringes two Oura patents covering its design and internal components, including the battery and sensors. Oura is seeking monetary damages and a permanent injunction that would stop Ultrahuman from selling the device in the United States.
The case lands just months after the Ring Pro helped the Bengaluru-based startup return to the US market. Ultrahuman's earlier Ring Air was hit with an import ban after Oura won a patent infringement ruling from the US International Trade Commission in August last year. Ultrahuman launched the redesigned Ring Pro in February and received a favorable US Customs and Border Protection ruling in March, clearing its path back into the country.
The patents at the center of the Oura vs Ultrahuman fight
Oura argues that the Customs ruling covered only the patent involved in the earlier dispute, not the two patents cited in the new lawsuit: D804,471 and 12,769,363. The second patent is notably fresh, issued to Oura on October 20, just two days before the company filed its complaint. It covers a smart ring design that incorporates internal components such as a curved battery, circuit board, magnets, and sensors.
