What is the scope of protection of patent right?

The scope of patent protection refers to the technical characteristics and technical scope of the invention-creation within the validity period of the patent right. Therefore, the scope of patent right is the protection scope of patent right. [1] Paragraph 1 of Article 59 of China's Patent Law stipulates that the scope of protection of the patent right for an invention or utility model shall be subject to the content of its claim, and the claim may be explained by the specification and drawings. Article 20 of the Detailed Rules for the Implementation of the Patent Law stipulates that the patent claim shall specify the technical features of the invention or utility model and clearly and concisely state the scope of the requested protection. Therefore, when determining the scope of patent protection, firstly, the content of the patent right shall prevail, in which "Yi" refers to the essential content of the technical characteristic parameters recorded in the patent right. On this premise, the patent right can be explained by using the specification and attached drawings. The legal protection of patent right is the protection of the rights and interests of the patentee by the laws of a country, but patent right is an intangible property right, which is different from tangible property and it is not easy to define its protection scope. To this end, legislators have produced and adopted different theories, which have become legal principles.
