What inventions can't be patented?

In China, there are three kinds of patent applications: invention, utility model and design. What inventions can't be patented? These three patent applications are called invention patent application, utility model patent application and design patent application respectively. After being authorized, they are called invention patent, utility model patent and design patent respectively. At this point, the applicant is the patentee of the corresponding patent. Patent application is a necessary procedure for obtaining patent right. To obtain a patent right, the applicant shall file an application with the State Patent Office, which shall approve and issue a certificate. When filing a patent application with the State Patent Office, the applicant shall also submit a series of application documents, such as the request, specification, abstract and patent claim. In terms of patent application, the provisions of the patent laws of all countries in the world are basically the same. So can all inventions be patented? Actually, it's not like this. According to the relevant provisions of China's patent law, the following items are not granted patent rights: 1, scientific discovery; 2. Rules and methods of intellectual activities; 3. Diagnosis and treatment of diseases; 4. New varieties of animals and plants; 5. Obtaining substances by nuclear transformation.
