1, the patent application needs to be creative, that is, the invention-creation must have substantial characteristics and progress, and it has certain novelty and creativity compared with the existing technology. The added suite is not directly related to other parts of the patent application or has no substantive features and progress, so adding the suite will affect the novelty and creativity of the patent application and lead to the rejection of the application.
2. Patent application should follow the "single principle", that is, one application can only file a patent application for one invention. If an application contains multiple packages, it violates the principle of oneness and will lead to the rejection of the application.
