Can a supplemental amendment be filed after a final Office action?
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.
Yes, a supplemental amendment can be filed after a final Office action, but its entry is not guaranteed. The MPEP 714.03(a) provides guidance on this:
“A supplemental amendment filed after a final action or after an appeal has been taken from a final rejection will not be entered unless approved by the examiner.”
When considering whether to enter a post-final supplemental amendment, examiners typically look for:
- Amendments that place the application in condition for allowance
- Amendments that do not raise new issues requiring further search or consideration
- Amendments that address objections or rejections in the final Office action
If the supplemental amendment doesn’t meet these criteria, the examiner may deny entry. Applicants should provide a clear explanation of why the amendment should be entered when filing after a final action.
