Last year, Oura successfully sued Ultrahuman and got a court to block sales of its Ring Air product in the US. Now, Oura has sued Ultrahuman again in a Texas federal court over its latest product, the Ring Pro, saying it violates two of its patents involving design and internal components, according to a Oura's blog post. Oura is seeking monetary damages and wants to (again) stop Ultrahuman from selling its latest wearable.
