It does not distinguish whether it is from Chengdu or not, it is the same across the country. The differences are:
(1) The inventiveness of utility models is lower than the requirements of my country’s patent law for applying for invention patents. Yes, it has outstanding substantive features and significant progress compared with the prior art before the filing date; and the requirement for a utility model is that it has substantive features and progress compared with the prior art before the filing date. For inventions, "outstanding substantive features" and "significant progress" are emphasized, while for utility models, only "substantial features and progress" are mentioned. Obviously, the degree of creativity of an invention is higher than that of a utility model.
(2) The scope of utility models is smaller than that of inventions. Since inventions are new technical solutions proposed for products, methods or their improvements, inventions can be product inventions or method inventions. It can also be an improved invention. Only product inventions can be shaped product inventions or unshaped product inventions. Moreover, unless there are special provisions in the patent law, any invention can obtain patent rights in accordance with the law. However, the scope of applying for utility model patent rights is much narrower. It is limited to practical new technical solutions proposed by the shape, composition or combination of the product. In this way, various manufacturing methods cannot apply for utility model patents. At the same time, it is impossible to create a utility model for products that have nothing to do with shape, structure or combination thereof. Therefore, the scope of utility models is much narrower than that of inventions and is limited to innovative designs related to the shape, structure or combination of products.
(3) The protection period of utility model patents is shorter than that of inventions. my country’s patent law expressly stipulates that the protection period of utility model patents is 10 years, calculated from the filing date. The protection period for invention patents is 20 years. In contrast, the protection period of a utility model patent is much shorter than that of an invention patent. This is because, under normal circumstances, the creation process of a utility model is simpler and easier than that of an invention, and the time to realize its benefits is also much shorter. Therefore, the legal provisions on its protection period are correspondingly shorter.
(4) The approval process for utility model patents is simpler than that for invention patents. According to the provisions of my country’s Patent Law, after the Patent Office receives an application for a utility model patent and is deemed to meet the requirements of the patent law after preliminary examination, it will no longer be After conducting substantive examination, the application will be announced, the applicant will be notified, and a utility model patent certificate will be issued. For invention patents, they must go through substantive examination, and the examination procedures and time are much more complicated and longer than those for utility models.
