Do I need to apply for a patent for gift box packaging?

It depends on the characteristics of your packaging design. It is impossible to apply for a patent for appearance in the design of plane printed matter mainly using patterns, colors or a combination of the two. After the revision of the new patent law in 2008, Article 25 of the patent law clearly pointed out that the types that are not granted patent rights include "designs that mainly play a logo role in patterns, colors or the combination of the two." If the features in your packaging design are not only patterns, colors or a combination of the two, nor are they mainly used for identification, then you can apply, otherwise, even the application will not be authorized.
