Whose question is misleading? Whether substantive examination is required depends on the type of application. Invention patents require substantive examination. Utility models and designs do not require substantive examination; but applications for utility models cannot It is a method-type invention. In this question, only the product structural design can apply for a utility model. However, it does not mean that only the structural design can apply for a new type. You can still apply for an invention. Therefore, the "original intention" of the person who asked the question should be to choose B, but the message conveyed in this way is: if the structural design of the product is patented, there is no need to conduct substantive examination. . . . This is really far from the mark. .
