When will the annual patent fee be paid?

(1) The applicant shall pay the patent registration fee, announcement printing fee, stamp duty and the annual fee for the year when the patent right is granted. Where an application for a patent for invention needs to pay the application maintenance fee, the applicant shall pay the application maintenance fee for each year together. Failure to pay or pay the full fee at the expiration of the period shall be deemed as failure to go through the registration formalities. The annual fee for the year when the patent right is granted shall be paid within the time limit specified in the notice of granting the patent right issued by the Patent Office, and the annual fee thereafter shall be paid in advance within one month before the expiration of the previous year.

(2) Need to pay the application maintenance fee. Where an application for a patent for invention has not been granted a patent right for two years from the date of filing, the applicant shall pay the application maintenance fee from the third year.
