When is the issue fee due for a patent application?

The issue fee for a patent application is due 3 months from the date of the Notice of Allowance. As stated in MPEP 1306:

“The issue fee and any required publication fee are due 3 months from the date of the Notice of Allowance. The period for payment of the issue fee and any required publication fee is not extendable, see 37 CFR 1.311(a).”

It’s important to note that this deadline cannot be extended, so applicants should ensure timely payment to avoid potential abandonment of their application.
