What is the specific situation that scientific research does not grant patents?

According to the provisions of the patent law, an invention can be patented as long as it has the necessary conditions for obtaining a patent. According to the characteristics of patent protection and China's economy, China's patent law has made exceptions for some topics that cannot be patented. What are the circumstances in which the patent right is not granted? Patent authorization 1. Scientific discovery is only an understanding of natural laws, not an invention made by using natural laws. Can not be directly applied to production practice, does not have industrial practicability, so no patent right is granted. 2. Rules and methods of intellectual activities. It only guides people to think, identify, judge and remember the information they express, without using technical means or obeying the laws of nature. It has no technical characteristics, so it can't be patented. 3. Diagnosis and treatment of diseases The diagnosis and treatment of diseases refers to the process of identifying, determining or eliminating the causes or pathological changes of living people or animals, which cannot be used in industry and is not practical. Not an invention in the sense of patent law. Therefore, such methods cannot be patented. 4. Animal and plant varieties refer to the animal and plant varieties themselves, excluding the methods of producing animal and plant varieties. If the intervention of artificial technology plays a major control or decisive role in the purpose or effect of this method, this method does not belong to a mainly biological method. Patents can be granted. The substance obtained by nuclear transformation can be used for military purposes, and for the vital interests of the country, the patent law stipulates that no patent shall be granted. It should be pointed out that not only the substance obtained by nuclear transformation method can not obtain patent protection, but also the nuclear transformation method itself can not obtain patent protection.
