You can apply for a PCT patent application.
PCT patent application process:
(1) First file a domestic patent application with the China Patent Office, and then file an international application within the 12-month priority period:
(2) File an international application directly with the China Patent Office and specify China in the international application.
To file an international application, you must entrust a foreign-related patent agency designated by the China Patent Office authorized by the State Council to handle it. The China Patent Office does not accept applicants to submit international applications directly. The PCT Division of the China Patent Office is responsible for accepting international applications submitted to the China Patent Office. The agencies established by the China Patent Office across the country do not accept international applications. Chinese nationals or residents may also submit international applications directly to the International Bureau of WITO. International application documents can be submitted to the PCT Section of the China Patent Office through the prescribed patent agency in person, by registered mail, or by fax. If submitted by fax, the original document must be delivered to the China Patent Office through the prescribed patent agency within 14 days from the date of fax. Otherwise, the fax will be deemed not received. The date when the Chinese Patent Office actually receives the international application documents that meet the acceptance conditions is the international filing date. If submitted by fax, as long as the fax meets the acceptance conditions and the original is delivered within the specified time, the date of the fax will be the international filing date.
If the submitted international application documents do not meet the acceptance conditions, the applicant is allowed to make corrections within 30 days from the date of submission, and the date when the corrections meet the acceptance conditions will be the international application date.
Those who file an international application must pay transmission fees, search fees and international fees (including basic fees and designation fees) within one month from the international filing date. The designation fee can be paid within the above period or within 12 months from the priority date.
