Does the national patent application need physical objects?

First, does the national patent application need physical objects? There are three kinds of patents in China: invention patents, utility model patents and appearance patents! Invention patents protect technology and methods, utility models protect structure, and appearance protects the external surface of products. When applying for an appearance patent, you can take six views of the real thing, or you can submit the line drawing of the product to the State Bureau for protection. For inventions and utility models, you can apply as long as they can be manufactured, but you don't have to take out the real thing. You need to submit the attached drawings when applying! Generally speaking, it is not necessary to make physical objects unless there is reason to believe that making physical objects will help pass the substantive examination. This situation mainly appears in the following aspects: the application documents are written correctly and there are no major defects, but the examiner can't understand the invention due to technical reasons. At this time, the applicant requests to meet with the examiner, and takes the physical object as a reference after obtaining permission, which can help the examiner understand the document and help the smooth authorization. But as far as I know, this kind of situation is rare, so the physical object is unnecessary. In a word, the examiner decides whether to authorize according to the information recorded in the application documents, regardless of whether the applicant has made the physical object. So the key is how to write a good document for the examiner to understand. Second, what is the substantive examination of the patent? To put it simply, there are three kinds of domestic patents: invention patents, utility model patents and design patents, among which only invention patents can be authorized through "preliminary examination" and "substantive examination", and the other two can only be authorized through "preliminary examination". In addition, the main difference between substantive examination and preliminary examination is: 1. The substantive examination is conducted at the request of the applicant, and the applicant needs to pay the fee at the same time. If the applicant fails to pay the fee or make a request within the prescribed time limit, even if the application for invention has been published, it will be regarded as withdrawn, that is, the contribution to society is futile and the patent right cannot be obtained. The request for preliminary examination was made by default when the application was submitted. Applicants only need to pay the basic application fee and publication fee and submit documents that meet the legal requirements, so that their applications can enter the preliminary examination procedure. 2. The content of substantive examination is much more than that of preliminary examination, and the requirements are relatively strict, which puts forward higher standards in novelty, creativity and practicality, disclosure of instructions, and whether the writing of claims meets the requirements. If it meets the standard, it will be authorized, and if it does not meet the standard, it will be rejected. 3. Because the examiner's standard is higher and the workload is bigger, the duration of the substantive examination procedure is much longer than that of the preliminary examination. For example, the preliminary examination may only take 3 months, while the substantive examination often takes 1-3 years or even longer. During this period, the applicant needs to submit the reply and amendment opinions to the application documents within the specified time according to the requirements of the examiner until the application documents meet the authorization standards. Otherwise, the examiner has the right to refuse.
