What is the purpose of filing a supplemental oath or declaration after allowance?

The purpose of filing a supplemental oath or declaration after allowance is to cover the claims in the application as they stand at the time of allowance. While the MPEP section 603.01 doesn’t explicitly state the purpose, it implies that these documents are filed to ensure that all claims are properly supported by an oath or declaration. The section states:

“Supplemental oaths and declarations covering the claims in the application may be filed after allowance as a matter of right.”

This allows applicants to provide additional sworn statements or declarations that may be necessary to fully support the allowed claims, without changing the content of the application itself.
