What is the improved patent? What are the requirements for improving patents?

What is the improved patent? In fact, simply speaking, it is to transform the existing patent base, and the main patent application is utility model patent. What are the conditions for improving patents? What is the improved patent? What are the requirements for improving patents? What is the improved patent? What are the requirements for improving patents? In fact, the so-called improved patents are generally applied for utility model patents. In other words, they are all modified on the basis of others' achievements, but only need to apply for patents. This change must meet the requirements of patent authorization, that is, at least it must be novel, creative and practical. Principle of equivalence. When the principle of universal application is applied to determine that the alleged infringement does not constitute patent infringement, the principle of equivalence should be applied to determine the infringement. The principle of equivalence means that one or more technical features of the object accused of infringement are different from those protected by the independent patent claim, but they can be identified as the same technical features after analysis. The principle of universal coverage. Also known as the complete technical feature coverage principle or the literal infringement principle. That is, if the technical features of the object accused of infringement include all the necessary technical features recorded in the claim, it belongs to the protection scope of the patent right. When the necessary technical features recorded in the patent independent claim adopt the upper conceptual features and the accused infringer adopts the corresponding lower conceptual features, the accused infringer falls into the scope of patent protection. The principle of complete treatment of technical characteristics. That is, the principle of treating the technical content recorded in the claims as a complete technical solution. When judging infringement, all the necessary technical features of the technical scheme recorded in the claim shall be compared with all the technical features of the accused infringing object one by one. The principle that the contents of the claims shall prevail. It is necessary to avoid adopting the principle of perimeter restriction, that is, the protection scope of patent right is exactly the same as that recorded in the written claim, and the claim only defines a general invention core, and the protection scope can be extended to the extent that technical experts think it belongs to the protection scope of the claim after reading the specification and drawings. What is the improved patent? What are the requirements for improving patents? That's all. I hope it helps you.
