There are several types of patents related to medical treatment.

The so-called patent in the medical field refers to instruments or devices that can be granted patent rights and used to implement disease diagnosis and treatment methods, as well as substances or materials used for disease diagnosis and treatment methods. Mainly includes: the invention of medical chemicals (pharmaceutical compounds); Invented a pharmaceutical composition with a pharmaceutical compound as an active ingredient; Methods for preparing pharmaceutical compounds or preparations; Invention of medical use of pharmaceutical compounds or preparations; The invention of medical devices; Microbial invention, etc. What needs to be pointed out here is that, due to humanitarian considerations and social and ethical reasons, Article 25 of China's Patent Law stipulates that the diagnosis and treatment of diseases are not granted patent rights.
