First of all, we must find out whether it is really infringement. First of all, we must find out whether the other party really has exclusive rights. Sometimes, because the annual fee is not paid on time, or the other party's patent has some problems and does not meet the requirements of patent application, the exclusive right of the other party is not protected by law. These all need to be reviewed. Secondly, we should compare our products with patents and pay special attention to the technical characteristics in patents. If our products do not meet these characteristics, it can be used as a reason for non-infringement defense. Second, if there is real infringement, we should actively bear the tort liability. Generally speaking, it is necessary to stop the infringement, eliminate the influence and compensate for the losses.

Legal basis:

Article 28 of the Civil Procedure Law of People's Republic of China (PRC) shall be under the jurisdiction of the people's court of the place where the infringement occurred or the defendant's domicile.
