There are certain facts that need to be ascertained before a Design can be considered registrable as an industry Design. Not all Designs will be able to be covered by an Industrial Design unless they adhere to certain guidelines. Most pertain to the uniqueness of the Design and whether it is an aesthetic or visual aspect of a Design.
For your Industrial Design to be registrable, it must have novelty. This basically means that the exterior Design that you wish to protect, whether a colour scheme, pattern, or shape, it should be completely unique compared to other products in the public domain.
