What are the universally applicable principles of patent infringement?

What are the universally applicable principles of patent infringement? Patent infringement first needs to be identified as infringement and patent infringement. We must first know what the principle of universal coverage is. Principle of universal coverage is one of the most basic principles to judge patent infringement. The so-called universal application principle means that if the accused object or method is infringed, then the product or method should have every feature described in the patent claim and be indispensable. What are the universally applicable principles of patent infringement? When judging patent infringement, the principle of universal coverage should be applied first. In the following cases, it is considered that the defendant has completely covered the claim. The first point is literal infringement. In other words, through literal analysis and comparison, it can be concluded that the technical characteristics of the defendant are the same as the necessary characteristics of the patent. Second, this patent claim uses the upper concept, and the structure disclosed by the defendant belongs to the specific concept in the upper concept. In this case, the principle of universal coverage is applicable and the defendant infringes. Third, the accused technical features are more than the necessary technical features of the patent, that is to say, compared with the patent claim, the accused technical features not only contain all the features of the patent claim, but also add features. This situation is still infringement, because as long as the accused covers all the features of the patent claim, it belongs to infringement, regardless of whether there are more accused than the claim.
