What are the advantages of applying for foreign patents through PCT?

1. The entry time limit for Paris Convention is 12 months, and the PCT application is 30 months. Applicants can have more time to evaluate the application prospect of their own technology, the development potential of foreign markets and the preparation funds (most of the expenses of PCT applications occur in the national stage). 2. In the international phase, the applicant can obtain the international search report and the international preliminary examination report according to the request, so as to make a preliminary judgment on the authorization prospect after entering the national phase, which is convenient for the applicant to make a decision on whether to enter the national phase.
