What should I do if I miss paying the annual fee for the invention patent?

Obtaining patent right is a very troublesome thing, and the success rate is very low, especially for invention patents, the approval rate is even less than 50%. Therefore, after the patent right of an invention patent is approved, the annual fee for the invention patent must be paid on time. What should I do if I miss the time to pay the annual fee for invention patents? The current patent law in China stipulates that the patentee shall pay a certain fee every year from the year when the patent is granted to the expiration of the patent protection period to maintain the effectiveness of the patent right, and the annual patent fee shall be paid in advance within one month before the expiration of the previous year. What if the patentee of the invention patent misses to pay the annual fee? If he misses paying the annual fee, he can repay it within six months from the date of application. If it exceeds six months, the patent office will issue a notice of termination of the patent right. Within two months from the date of receipt of this notice, you can go through the formalities of rights restoration in China National Intellectual Property Administration and pay the annual fee and restoration fee. If the above time is exceeded, the patent right will be terminated and cannot be restored, and the applicant can only apply again after improving his patent.
