Can a supplemental oath or declaration be filed after allowance of a patent application?

Yes, supplemental oaths and declarations covering the claims in a patent application can be filed after allowance. The Manual of Patent Examining Procedure (MPEP) states:

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

This means that applicants have the right to submit additional oaths or declarations even after their patent application has been allowed.
