How long should I wait before inquiring about the status of my amended patent application?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

For amended patent applications, the USPTO provides guidelines on when to inquire about the status. According to MPEP 203.08:

Amended applications are expected to be taken up by the examiner and an action completed within two months of the date the examiner receives the application. Accordingly, a status inquiry is not in order after reply by the attorney until 5 or 6 months have elapsed with no response from the Office.

If six months have passed without a response, you should inquire about the application’s status to avoid potential abandonment. It’s recommended to use Patent Center or Private PAIR for status inquiries.
