I designed a robot myself. How long is the payment period of patent priority?

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. If the payment is not made within one month before the expiration, the Patent Office will grant a grace period of one month. If the fee is not paid within one month after the expiration, a late fee will be incurred. ## 1. The applicant shall pay the application fee, publication printing fee and necessary application surcharge within 2 months from the date of application or within 5 days from the date of receiving the acceptance notice; 2. If it is not paid or paid in full, the application shall be deemed to be withdrawn. 3. Where the applicant claims priority, he shall pay the priority claim fee at the same time as the application fee; Failure to pay or pay in full at the expiration of the time limit shall be deemed as failure to claim priority. 4. Where a party requests substantive examination or reexamination, it shall pay the fee within the relevant time limit stipulated in the Patent Law and its detailed rules for implementation; Failing to pay or pay in full at the expiration of the time limit shall be deemed as not making a request. 5. When going through the registration formalities, the applicant shall pay the patent registration fee, announcement printing fee and the annual fee of the year when the patent right is granted; Failure to pay or pay in full at the expiration of the period shall be deemed as failure to go through the registration formalities. 6. The annual fee after the year in which the patent right is granted shall be paid before the expiration of the previous year. If the patentee fails to pay or fails to pay in full, the patent administration department of the State Council shall notify the patentee to pay the annual fee within 6 months from the date of expiration, and pay the late fee at the same time; The amount of the late payment fee is calculated by adding 5% of the full annual fee of the current year for every 1 month that exceeds the prescribed payment time; If it is not paid at the expiration of the time limit, the patent right shall be terminated from the date when the annual fee should be paid. 7. The claim fee for restoring rights shall be paid within the relevant time limit stipulated in the detailed rules for the implementation of the Patent Law; Failing to pay or pay in full at the expiration of the time limit shall be deemed as not making a request.

Description item change fee, patent evaluation report request fee and invalidation request fee shall be paid within 1 month from the date of filing the request; Failing to pay or pay in full at the expiration of the time limit shall be deemed as not making a request.
