The electronic system of patent application only changes the original paper document into electronic version, and the process has not changed.
You should always check the documents received by the electronic system.
After submitting a patent application through an electronic terminal, you will receive a receipt indicating that you have successfully submitted it.
After one to three days, you will receive the Notice of Acceptance and the Notice of Payment of Application Fee (or the Notice of Examination and Approval of Fee Reduction), and you can pay the fee according to the time and fee specified in the notice.
The time to pay the application fee is stipulated by law within two months from the date of application, or within 15 days after receiving the acceptance notice, whichever is later.
