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

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.
