The legal fight between Oura and Ultrahuman is heating up again in the US smart ring market. After an earlier patent dispute forced Ultrahuman to pull the Ring Air from the country, the company is now facing a new lawsuit over its redesigned Ring Pro.
Last year, Oura accused Ultrahuman of patent infringement, and the court ruled in Oura’s favor. As a result, Ultrahuman stopped selling the Ring Air in the US. The company later returned with the Ring Pro, claiming it had resolved the previous patent issues.
Now, Oura has filed another lawsuit alleging that the Ring Pro infringes two additional patents related to its design and internal hardware. Oura is seeking monetary compensation and is asking the court to stop all US sales of the Ring Pro.
The case is being handled in a federal court in Texas because the Ring Pro is manufactured for the US market in Plano by SVTronics. Oura has also named SVTronics as a defendant in the lawsuit.
Ultrahuman says the Ring Pro was specifically redesigned to avoid infringing on Oura’s patents. The company also claims that US Customs and Border Protection approved the new design and confirmed it does not violate Oura’s rights. However, one of the patents cited by Oura was granted only two days before the lawsuit was filed.
For now, Ultrahuman’s products remain available in other markets, and the Ring Pro continues to be sold in the US unless a court ruling says otherwise.
