Is the classification of the State Patent Office a type of patent? For example, patents for inventions, utility models and designs?

I. Publication of an application for a patent for invention The publication of an application for a patent for invention means that China National Intellectual Property Administration will publish the description and abstract recorded in the request in the bulletin of the patent for invention, and publish the description, drawings and claims of the application for a patent for invention in full respectively. China's patent law stipulates different ways of disclosure for invention patent applications and utility model and design patent applications. An application for a patent for invention shall be published at the expiration of 18 months from the date of filing; Applications for patents for utility models and designs shall be published at the time of authorization announcement. The reason is that the application for a patent for invention has to go through substantive examination, and the examination period is long. If the contents of the application are made public after the substantive examination is completed, the possibility of repeated research, investment and application on the same subject will be greatly increased, and the role of the patent system will not be well played. On the other hand, if the disclosure is late, the applicant will have more time to finally decide whether to disclose its technology or prepare for it. The time limit for publishing an application for a patent for invention is 18 months, which is mainly based on the following considerations: after filing a patent application for the first time abroad, the applicant still enjoys the priority period of 12 months in China, and may not file a patent application in China before the expiration of this time limit. However, after he filed a patent application in China, it will take some time for China National Intellectual Property Administration to conduct preliminary examination and publication, so it is stipulated to give 18 months. This is the practice adopted by most countries in the world, and it is also a reasonable time limit after practice. Second, the preliminary examination of an application for a patent for invention is a review of the contents of the application documents, and it is a necessary procedure between accepting and publishing the application. The scope of preliminary examination mainly involves the following aspects: (1) Examination of obvious substantive defects. The obvious substantive defects that should be examined include: whether the subject matter of the application for a patent for invention obviously does not belong to the invention specified in the Patent Law and its detailed rules for implementation, whether the subject matter of the application for a patent for invention obviously violates the national laws, social ethics or harms the public interest, whether the content of the application for a patent for invention obviously falls within the scope of not granting a patent right, and whether the application obviously does not conform to the provisions on the singularity of invention. In the preliminary examination, when the examiner requests the applicant to modify the application for the purpose of publishing the application, whether the modification proposed by the applicant is obviously beyond the scope recorded in the original specification and claim, and whether the writing of the specification and claim is obviously inconsistent with the relevant provisions. In principle, the preliminary examination does not examine substantive issues. The above-mentioned substantive defects should be limited to "obvious" and affect publication. (two) review the subject of application and agency matters. (3) Examining whether the application documents submitted by the applicant and other documents related to the patent application meet the formal requirements stipulated in the Patent Law and its detailed rules for implementation. (4) Examination of some special patent applications. It belongs to the special examination of divisional application or application involving biological materials that need to be preserved. (5) Consideration of other issues. For example, an application for a patent for invention accepted by China National Intellectual Property Administration that involves national defense secrets and needs to be kept confidential shall be handed over to the relevant competent authorities for examination and investigation. Iii. substantive examination of an application for a patent for invention China implements a substantive examination system for an application for a patent for invention, that is, not only preliminary examination, but also substantive examination. Substantive examination refers to China National Intellectual Property Administration's careful study of the application documents of an application for a patent for invention, looking for the invention that needs protection, determining whether the application conforms to the provisions of the Patent Law and its detailed rules for implementation, especially the provisions on patentability, and finally making a decision on whether to grant a patent right. The procedure of substantive examination begins when the substantive examination department in China National Intellectual Property Administration receives the application documents sent by the preliminary examination department, and ends with the notice of granting the invention patent right or the decision to reject or withdraw the application. The content of substantive examination mainly includes: (1) Whether the subject matter of the patent application is an invention in the sense of the Patent Law and its detailed rules for implementation, and whether it belongs to the scope where the patent right cannot be granted. (2) Whether the subject matter of the patent application violates national laws, social morality or harms public interests. (3) Whether the patent application meets the requirements of the singularity of invention. (4) Whether the applicant's application for amendment or division is beyond the scope recorded in the original specification (including attached drawings) and the claims. (5) In the case of applying for priority, if it is found that someone else filed another patent application on the same subject between the priority date and the application date, or after searching, it is found that relevant comparative documents were made public during this period, whether the priority claim is established shall be examined. (6) According to the retrieved comparison file, judge whether the technical scheme required to be protected by the invention patent application is novel and creative, and judge whether the invention required to be protected is practical. (seven) whether the specification has made a clear and complete description of the invention required by the application for a patent for invention, so that the technical personnel in the field can realize it. (8) Whether the claim clearly and concisely states the scope of protection, whether the claim is based on the specification, and whether the independent claim includes the necessary technical features to solve the technical problems to be solved by the invention. Some of the above substantive issues have been involved in the preliminary examination, but the preliminary examination only solved the obvious substantive defects and will be further reviewed in the substantive examination.
