A company with the name "Secure Axcess" files a lawsuit against Nintendo Co., Ltd, allegedly because of the function of the Wii U and the Wii U GamePad, which is considered by them to be an example of patent infringement.
For specification, they were focusing on "multiple screens" that are disclosing two different samples of information (Example: The "Wii U Menu" by default will show a large grid of icons on the Wii U GamePad, while the television display shows a "hub" setting known as WaraWara Plaza.).
