(1) The PCT application is published internationally by the International Bureau 18 months from the priority date, so there is no situation where it is published in some countries and not in some countries.
(2) According to the revised rules in 2004, all designated countries are automatically designated when submitting a PCT application. Unless certain designated countries are specifically excluded after the international application is filed, the PCT application will enjoy the legal effect of a general national application in all designated countries from the date of the international application.
(3) PCT is only a patent application process, not a patent granting process. The final authorization decision is made by each designated office. Therefore, only by obtaining authorization from a designated office can you obtain patent protection.
