Please enter your PCT application # and password on the ISA/202. The list will contain the copies of the ISR/WO if they are issued.

* In KIPO’s PCT ISA portal system, please kindly note that if it is your first time, you will need to run/install the executable program, i.e. “raonkSetup.exe” application on your computer to download/upload the documents. You might find any pop-up message for it on the bottom (or top) of the screen and click " run" or "save" when you see the message. Once you installed it, you will not need to do it again next time.
