Anyone who wants to exploit a patent must obtain the permission of the patentee and pay the royalties according to the agreement of both parties, otherwise it will constitute infringement. Within the validity period of authorization, the patent right can only be used by the applicant or the licensee; After the patent expires, anyone can use the patent for free and become the wealth of the whole society. The patent right is valid only in the country where the patent right is granted, and other countries are invalid.
Exclusivity, monopoly, also known as monopoly or exclusivity, patent right is the exclusive right granted to the applicant or his legal assignee by the competent government department according to the application of the inventor or applicant that his invention meets the conditions stipulated in the patent law; Timeliness, the so-called timeliness of patent rights, means that patent rights have a certain period of time, that is, the protection period stipulated by law.
