Patents are a little different from others.

First of all, it is clear that the process of judging patent infringement is a very complicated process, which seems to be not necessarily infringement. The identification of patent infringement is to compare the technical scheme recorded in "patent claim" in the patent authorization public text with the real object of the infringing product. So you should look at the technical scheme recorded in the patent "claim" first, and then compare it with the products you produce. If the product you produce is different from the technical scheme recorded in the Claim, its working principle is different and its effect is different, then there should generally be no problem of infringing the patent right.

Secondly, the patent law is a national law, and China's patent law covers Chinese mainland, that is, the patented technology authorized in China is protected in Chinese mainland.

Finally, remind everyone not to flinch from patented products. If someone tells you that you have infringed his patent right, don't panic. First, it is determined whether the patent right is still valid. After the patent right is confirmed to be valid, study the technical scheme of the patent claim and compare it with your own products. It is best to find a professional (patent agent) to help you deal with the above matters, and then make the next decision according to the judgment results. Not necessarily when the defendant will lose money, but also when he will make money, hehe.
