Is there a deadline for the reply of priority review?

The time limit for the applicant to reply to the notice of examination opinions on the invention patent is 2 months from the date of issuance, and the time limit for the applicant to reply to the notice of examination opinions on the utility model and design patent is 15 days from the date of issuance. "Posting date" means the posting date indicated in the notice. The time limit for responding to the notice of priority examination in patent re-examination cases and patent invalidation cases is the same as that in ordinary cases.
