Can American patent infringement litigation judgments be enforced in China?

The judgment of American patent infringement lawsuit cannot be enforced in China. A patent applied abroad is not protected if it is not an international patent and has not been applied at home. Because the patent itself is regional, the acquisition of the patent right must be applied and granted by the patent administration department of a country in order to enjoy the monopoly right within the jurisdiction of that country. That's why there are China patents and American patents.

Relevant regulations

Where an application for a patent for invention is filed in a foreign country, the patent administration department in the State Council may require the applicant to submit the information retrieved by the country or the information of the examination results within a specified time limit. If the application is not submitted within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn.

The international patent is because China joined the Patent Cooperation Treaty on 1994 1 month 1 day. In this way, one country is applicable and many countries are effective. This method is divided into international stage and national stage.
