How do enterprises apply for foreign patents?

1. How do companies apply for foreign patents? It is recommended to consult a professional patent agency. Because no matter PCT international application or single country application, it is necessary to entrust the State Council to authorize a foreign-related patent agency designated by China Patent Office to handle it. The specific procedures are summarized as follows: if a unit or individual applying for PCT international application in China applies for international application, it shall obtain the consent of the relevant authorities in the State Council, or declare to the Chinese Patent Office that the invention does not involve national security, and then it can apply in one of the following two ways. (1) First file a national patent application with the China Patent Office, and then file an international application within the priority period of 12 months: (2) file an international application directly with the China Patent Office, and designate China in the international application. To file an international application, a foreign-related patent agency designated by the China Patent Office shall be entrusted, and the China Patent Office does not accept the applicant to submit an international application directly. PCT Office of China Patent Office is responsible for accepting international applications submitted to China Patent Office. The representative offices set up by China Patent Office all over the country do not accept international applications. Citizens or residents of China can also submit their international applications directly to the WITO International Bureau. International application documents can be submitted in person, by registered mail or by fax to PCT Office of China Patent Office through the designated patent agency. If submitted by fax, the original shall be delivered to PCT of China Patent Office through the designated patent agency within 14 days from the date of fax, otherwise the fax shall be deemed as not received. The date when the Chinese Patent Office actually receives the international application documents that meet the acceptance conditions is the international application date. If it is submitted by fax, as long as the fax meets the acceptance conditions and the original is delivered within the specified time, the fax date is the international application date. 2. If the international application documents submitted at the time of application 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 is the international application date. Where an international application is filed, the transfer fee, search fee and international fee (including basic fee and designated fee) shall be paid within 1 month from the date of international application. The specified fee can be paid within the above period or within 12 months from the priority date. At present, China pays more and more attention to the research and certification of patented technology. Therefore, in some scientific research units or enterprises with patented technologies, it is often necessary to apply for some patented technologies, which involves not only the application of domestic patents, but also the identification of foreign patented technologies. Once a cross-border application is filed, it is very different from a domestic application in terms of time and procedure.
