How to judge whether there is patent infringement?

The method for jud whether a patent is infringe is as follows:

1 is relatively infringing. 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;

2. It 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 patent infringed by the defendant, or all the technical features in the infringed patent infringe the patent right of others;

3. It 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.
