What is a supplemental oath or declaration in patent applications?
A supplemental oath or declaration is a document that can be submitted to correct deficiencies or inaccuracies in an earlier-filed inventor’s oath or declaration. According to MPEP 603, it is provided for under 35 U.S.C. 115(h) and 37 CFR 1.67.
The MPEP states: 37 CFR 1.67(a) provides that the applicant may submit an inventor’s oath or declaration meeting the requirements of 37 CFR 1.63, 1.64, or 1.62 to correct any deficiencies or inaccuracies present in an earlier-filed inventor’s oath or declaration.
It’s important to note that while corrections can be made, no new matter may be introduced into a nonprovisional application after its filing date even if an inventor’s oath or declaration is filed to correct deficiencies or inaccuracies present in the earlier-filed oath or declaration.
