How to protect rights when discovering patent infringement?

First, collect evidence of the other party's infringement. For example, when collecting evidence, it is necessary to keep the original invoices and commodity details of infringing products, collect evidence under the supervision of a notary office when necessary, and seal up copies so that they can be presented in court.

Second, in the case of confirming the infringement of the other party, you can send a lawyer's letter to ask the other party to stop the infringement and make some compensation. If the other party ignores it, it can bring a lawsuit directly to the court or complain to the local intellectual property management authority.

Third, the court will make a ruling to stop the infringement from the source by filing an infringement lawsuit.

It should be noted that both the lawyer's letter and the complaint should be written by professional lawyers, so as to avoid unnecessary troubles caused by unclear facts and improper application of the law and delay the process of safeguarding rights.
