Spring Design, a California based technology company, has proven victorious in it’s patent battle against Barnes and Nobles that lasted a little over a year. Spring Design released it’s competing e-reader exactly one day prior to the Nook launch, resulting in immediate litigation. Under dispute was the employment of both a LCD and EPD (Electronic Paper Display) screen that both receive data from a single application. Under the settlement deal, Barnes and Noble will have to license the API from Spring Design.
