(3) Diagnosis and treatment of diseases.
The method of diagnosis and treatment of diseases refers to the process of identifying, determining or eliminating the cause or focus with the living human body or animal body as the direct implementation object. For humanitarian reasons and social ethics reasons, doctors should have the freedom to choose various methods and conditions in the process of diagnosis and treatment. In addition, this method is directly aimed at living human beings or animals and cannot be used in industry, so it is not an invention in the sense of patent law. Therefore, the diagnosis and treatment of diseases cannot be patented.
