Your products do not only operate in accordance to a technical function: they incorporate a form as well.
Industrial designs protect the form of manufactured products and handmade crafts, as well as their packaging. Also logos, graphic symbols and Graphical User Interfaces (GUI) of the software programs and apps can be protected by industrial designs.
Take into consideration that a registerable design does not need to be aesthetically beautiful: it is sufficient to be noteworthy and visually attractive. Just enough to make your products stand out from the rest.
