Which article of the Patent Law stipulates that design patents shall be subject to a registration system instead of an examination system?
Isn’t it misleading...
The reason why appearance patents and utility model patents are not subject to substantive examination is because their inventions have low creativity and large quantities. If they are subject to substantive examination, Review is a waste of resources, so only a preliminary review is conducted, and the substantive content is reviewed only when it is invalid or infringing.
Another situation regarding appearance patents is that not all WIPO member states include designs in patent protection, and some countries adopt copyright protection.
