Patent is the abbreviation of patent right. It is a document issued by a patent agency according to an invention application. Such documents describe the content of the invention and create a legal state, that is, the patented invention can only be used (including manufacturing, use, sales and import, etc.). ) In general, the protection of patents is limited by time and region. China's patent law divides patents into three categories, namely invention, utility model and design.
