I.

WHO MAY MAKE AFFIDAVIT OR DECLARATION

Anyone who has knowledge of the facts discussed in

the declaration may sign a declaration under

37 CFR 1.130

. In accordance

with

37 CFR

1.130

, however, it is the applicant or patent owner who may

submit (i.e., file) an affidavit or declaration. When an assignee, obligated

assignee, or person showing sufficient proprietary interest is the applicant under

35 U.S.C.

118

the applicant or their representative must be the party

that files the affidavit or declaration under

37 CFR 1.130

even if the

inventor or any party with knowledge of the relevant facts signed the affidavit or

declaration. In other words, the affidavit or declaration must be filed by a party

having authority to take action in the application. Authority to file papers in an

application generally does not lie with the inventor if the inventor is not the

applicant. See

MPEP § 2155.05

.
