What is the process of PCT international patent application? 1. Submitting international applications Generally speaking, PCT applications should be submitted to the National Bureau as the PCT acceptance bureau. When applying for a PCT patent, the applicant must state in which member countries the application is valid. These designated countries are called designated countries. 2. International retrieval 1) International retrieval is a closed process, and there is no communication between the applicant and the retrieval unit except for single or obviously wrong questions. 9 months from the priority date, or 3 months from the retrieval unit receiving the retrieval book, whichever is later, the retrieval unit will make a retrieval report or announce that it will not make a retrieval report in some cases. The retrieval report or announcement will be transmitted to the International Bureau and the applicant. 2) After 18 months from the international application date (or priority date), the International Bureau will publish the PCT international patent application and the search report made by the international search unit, and send the application together with the search report to the patent office of the designated country required by the PCT patent application. 3. International Publication 1) At the expiration of 18 months from the priority date, the International Bureau will publish the international application internationally. There are two kinds of publications: pamphlets and announcements. Publishing forms include paper and electronic parts. 4. International Preliminary Examination International preliminary examination only puts forward preliminary opinions on whether the invention is novel, creative and practical, and its examination opinions are not binding on each designated country. 5. After the designated country completes the international phase, the international patent application enters the national (or regional) phase after the applicant initiates the application.
