Intellectual property rights have strict regional characteristics, that is, intellectual property rights granted by competent authorities of various countries according to their own laws can only be protected by law within their own territory. For example, the patent right granted by China Patent Office or the exclusive right to use a trademark approved by China Trademark Office can only be protected in China, but not in other countries. Foreigners using invention patents authorized by China Patent Office outside China shall not infringe the patent right of China. Therefore, inventions made by China citizens and legal persons must apply for patents in foreign countries if they want to be protected in foreign countries.
