According to the provisions of Article 20 of China's Patent Law, any unit or individual who applies to a foreign country for a patent for invention or utility model completed in China shall file a confidentiality review with the patent administration department of the State Council in advance. The procedures and time limit for confidentiality review shall be implemented in accordance with the provisions of the State Council.
Units or individuals in China may file an international patent application in accordance with the relevant international treaties to which People's Republic of China (PRC) is a party. The applicant who files an international application for a patent shall abide by the provisions of the preceding paragraph.
The patent administration department of the State Council shall handle international patent applications in accordance with the relevant international treaties to which People's Republic of China (PRC) is a party, this Law and the relevant provisions of the State Council.
Where an invention or utility model that violates the provisions of the first paragraph of this Article is applied for a patent in a foreign country, the patent right shall not be granted in China.
Finally, after filing a patent application in China, you can file a foreign application through the Paris Convention mode and the PCT mode (in the latter case, you can also file a PCT application directly with China National Intellectual Property Administration).
