The application for a patent for a new type or design is also based on the date of publication of the authorization announcement issued by the China Patent Office plus 3 months as the authorization date. In which year is the sunset authorized and the annual fee paid; The applicant shall pay the patent certificate fee and annual fee as required after receiving the authorization notice. Those who fail to pay the annual fee within the prescribed time limit will be overdue for 6 months. If the annual fee is overdue, an additional 25% annual fee will be charged as a late fee. If the annual fee is not paid within the time limit, the China Patent Office will issue a notice to the patentee, which will be regarded as giving up the patent right and published in the patent gazette.
