The legal meaning of patent:
A patent is an invention protected by legal norms. It is an invention-creation that applies to the national examination and approval authority for a patent and is granted the exclusive right to invent within a specified time after passing the examination according to law.
Patent right is an exclusive right with exclusivity. If a non-patentee wants to use the patented technology of others, he must obtain the consent or permission of the patentee according to law.
The patent right granted by a country according to its patent law is only valid within the jurisdiction of that country and is not binding on other countries. Foreign countries do not undertake the obligation to protect their patent rights. If an invention is patented only in China, then the patentee only enjoys exclusive rights or exclusive rights in China.
The legal protection of patent right has timeliness. The term of invention patent right in China is 20 years, and the term of utility model patent right and design patent right is 10 years, counting from the date of application.
The two basic characteristics of patent are "exclusiveness" and "openness". "Proprietary" refers to the exclusive right granted by law to a technology inventor for a period of time; "Openness" means that the technical inventor makes his technology public in exchange for the exclusive right granted by law, so that the public can obtain the relevant information of patented technology through normal channels.
