However, if the application is deemed to have been withdrawn due to insufficient payment of the application fee, it shall not be required to refund part of the application fee already paid. Because the application procedure has started from the acceptance, after the application is accepted, the rights and other rights that are the basis of foreign priority and domestic priority are also obtained.
