I sold a training table on Taobao last year. Last month, I was sued in court for patent infringement dispute. How should I write a defense?

The defense period given by the court is only 15 days, counting from the time when you receive the legal documents. So we can't ignore it. You can start with the objection to jurisdiction, but you should still focus on the defense. You need to collect all kinds of evidence, and you'd better do a search. It will be used to maintain the existing design. If there is enough probative force, it can be used as a powerful evidence of invalidity and can also be used to negotiate with the other party. Because the defense strategy should be determined by combining the specific circumstances of the suspected infringing product and the patent involved, a prudent agent will not express his opinion until he sees the real object and the patent. Of course, you can do nothing, just admit it, prepare the money, and then either pay the money to settle with the plaintiff or wait for the court to decide.
