Can an inventor’s oath or declaration be amended after signing?
Generally, an inventor’s oath or declaration should not be amended after signing. The MPEP clearly states:
The wording of an oath or declaration should not be amended, altered or changed in any manner after it has been signed.
If there are issues with the oath or declaration, the proper course of action is typically to submit a new one. As the MPEP notes:
If the wording is not correct or if all of the required affirmations have not been made, or if it has not been properly subscribed to, a new oath or declaration should be submitted.
However, in some cases, minor deficiencies can be corrected without submitting a new oath or declaration. For example, if the oath does not set forth evidence that the notary was acting within their jurisdiction at the time the oath is administered the oath, a certificate of the notary that the oath was taken within their jurisdiction will correct the deficiency.
