International Stage The international stage is the first stage of the international application approval process. It includes the necessary procedures of international application acceptance, formal examination, international retrieval and international publication, as well as optional international preliminary examination procedures. Under normal circumstances, China Patent Office will make an international preliminary examination report within 9 months from the date of receiving the international preliminary examination request. 2. National Stage The national stage is the second stage of the international application approval process. The national phase is held in the patent office of the country where the applicant wishes to obtain the patent right (called the designated bureau or the selected bureau). Including the procedures for entering the national phase and the examination and approval procedures at each designated bureau or selected bureau. After the international application enters the national stage, the patent offices of various countries will examine it according to the provisions of their own patent laws and regulations and decide whether to grant the patent right. (4) What benefits can China applicants get from the PCT program? 1. Applicants can apply in Chinese; 2. The applicant may file an application with the Chinese Patent Office to request foreign countries to grant patent protection; 3. The applicant only needs to submit a set of Chinese (or English) application documents to the Chinese Patent Office to determine the application date of the application, which is regarded as an application filed in each designated country on the same day; 4. Before entering the national phase of each country, the applicant has obtained the international search report and the international preliminary examination report. Through these two reports, the applicant can preliminarily judge the prospect of the application being granted a patent right in patent offices in various countries, so as to decide whether it is necessary to continue the national phase; 5. Delay the entry into the national phase, so that the applicant can decide whether it is necessary to enter the scheduled designated country according to the market prospect and technological progress. Delaying the entry into the national phase generally does not affect the time for granting the patent right.
