The patent lawsuit lasted for several months.

Patent litigation usually takes six months, and if summary procedure is applied, it usually takes only three months to complete. However, patent dispute cases are generally very complicated, so it is very likely that the lawsuit will end in two years.

1. How long does it take to file a patent lawsuit?

Normal civil proceedings last for six months in the first instance and three months in the second instance. When the utility model and design patent are infringed, the defendant will often file an application for invalidation of the patent, and the infringement lawsuit will be suspended at the same time, which may last for two years.

For the lawyer of the plaintiff and the patentee, the most important thing is to collect evidence of infringement. It is important to buy infringing products, but some infringing products are counterfeit products of others, and the manufacturers mentioned above are not necessarily real infringing manufacturers. Therefore, it is best to go directly to the manufacturer to buy products suspected of infringement, and take notarization for evidence collection when necessary, or obtain evidence of infringement by the way when performing other duties through the administrative department for industry and commerce or the technical supervision department. The most difficult thing for the plaintiff to obtain evidence is to obtain the quantity of the other party's production and sales, and he can request the court to take evidence preservation measures to obtain evidence in this respect. Obtaining the evidence of infringement and the amount of infringement is the key to the plaintiff's success.
