The regionality, timeliness and exclusivity of patents determine that the legal protection of patent rights must meet certain conditions. The regionality of legal protection of patent rights includes formal conditions and substantive conditions. The formal conditions are: the regionality of legal protection of patent right. 1. The patent must belong to a valid patent. Some patent applicants think that after they get the patent application number, they get the patent right. In particular, some applicants for invention patents think that they have obtained the patent right after they have passed the preliminary examination and published it. These are all caused by the lack of patent common sense. Obviously, a patent that is truly fully protected by law must be an invention that has been granted a patent right, and it must be within the validity period of the patent right, otherwise it cannot be truly fully protected by law. 2. The patent must be a patent in an effective area protected by the laws of a country or region. Because the patent right is limited regionally, only inventions and creations that have been applied for and patented in a certain country are protected. For example, in China, only patents that have obtained the patent right in China are protected, and a foreign patent right is not protected by law in China. Of course, it is impossible to infringe foreign patent rights in China. Because some comrades in Chinese enterprises don't know the basic knowledge of patents, there have been cases in which when introducing foreign technology, the other party asked for the payment of foreign patent royalties in the contract and we readily agreed. If the content of foreign patented technology wants to be protected in China, the patent applicant must apply for the same technology to China within the prescribed priority period and obtain the patent right in China. Its substantive conditions are: what is the general principle for the legal protection of patent rights? Article 59 of China's Patent Law defines the general principle of the scope of patent protection: the scope of protection of the patent right for invention or utility model shall be subject to the content of its claim, and the description and drawings can be used to explain the claim. The general principles of the scope of patent protection determined by the patent laws of other countries are basically the same. According to the provisions of China's Patent Law, when determining the scope of protection of patent rights, the technical content recorded in the claims shall prevail. When the content given in the claim is unclear or inaccurate, comprehensive judgment can be made by combining the specification and the attached drawings of the specification.
