We all know Graphical User Interfaces from smartphones, tablets, and computers. The touchscreen enables controlling the device by activating graphical elements such as icons, scroll bars, windows, etc. In view of the graphical aspects of these elements, design protection and copyright are obvious choices for protecting sufficiently original work. However, for some GUIs patent protection can be achieved even though mere graphical elements are excluded from patenting. For being patentable, a GUI is required to provide a technical contribution.
