What is the standard for judging patent infringement?

Patents are things that no one has done before through their own brains, and then only apply for them through China National Intellectual Property Administration. This is a patent. When others apply for a patent, if you use the things of the patentee without the consent of the patentee, this situation constitutes patent infringement. Because our country attaches great importance to intellectual property rights, the law has a detailed description of patent infringement: what kind of situation will be judged as patent infringement. There are three ways to judge general patent infringement: the first is comparative infringement. Comparing the characteristics of patent application with those made by the defendant who infringed the patent one by one, we can see how many characteristics are the same. If almost the same is found through judgment, it goes without saying that it must be patent infringement, but if only a few parts are similar through comparison, it does not constitute patent infringement. The second method is the same infringement. The same infringement means that the technical features written on the infringed patent are exactly the same as those written on the defendant's infringing patent, or all the technical features in the infringed patent infringe the patent right of others. The third is equivalent to infringement. Equivalent infringement is a step that needs to be carried out on the basis of comparing the infringement and the same infringement. Equivalent infringement refers to using other people's patents to do similar things in the same way. Nothing is realized by your own brain. Through these three judgments on patent infringement, we can generally have a very clear standard on whether a patent is infringing. Patents are hard-earned by others. We can't just steal the fruits of other people's labor, which is disrespectful to others and will make us feel guilty. If we really need a patent, we should ask the patentee how to use it instead of stealing it directly.
