1. Exclusivity Exclusivity is also called monopoly or exclusiveness. Patent right is an exclusive right granted to the applicant or his legal assignee by the competent government department based on the application of the inventor or applicant and deeming that the invention meets the conditions stipulated in the Patent Law. It belongs exclusively to the patentee, and the patentee has the right to possess, use, benefit from and dispose of the object of its rights (i.e. invention and creation). 2. Temporality The temporality of patent rights means that patent rights have a certain time limit, which is the protection period stipulated by law. Article 42 of my country's Patent Law stipulates: "The term of invention patent rights is 20 years, and the term of utility model and design patent rights is 10 years, both calculated from the date of application." 3. Regionality, It is a spatial restriction on patent rights. It means that the patent rights granted and protected by a country or a region are only valid within the scope of that country or region and have no legal effect on other countries and regions. The patent rights are not confirmed and protected. If the patentee wishes to enjoy patent rights in other countries, he must file a separate patent application in accordance with the laws of other countries. Unless otherwise stipulated in international treaties and bilateral agreements, no country will recognize patent rights granted by other countries or international intellectual property agencies.
