When a supplemental oath is treated as an amendment
From Patentbarquestions
26. When, in accordance with the patent laws, rules and procedures as related in the MPEP,
is a supplemental oath or declaration treated as an amendment under 37 CFR 1.312?
(A) When filed in a nonprovisional application after the Notice of Allowance has been
mailed.
(B) When filed in a reissue application at any point during the prosecution.
(C) When filed in a nonprovisional application after the payment of the Issue Fee.
(D) When filed in a reissue application after the Notice of Allowance has been mailed.
(E) (A) and (D).
26. ANSWER: (D) is the most correct answer. MPEP § 714.16, third paragraph, states “a
supplemental reissue oath or declaration is treated as an amendment under 37 CFR 1.312
because the correction of the patent which it provides is an amendment of the patent, even
though no amendment is physically entered into the specification or claim(s).” Answer (A) is
incorrect because a supplemental oath or declaration is not treated as an amendment under 37
CFR 1.312 except when submitted in a reissue. See MPEP § 603.01. Answer (B) is incorrect
because a supplemental oath or declaration in a reissue will be treated as an amendment under 37
CFR § 1.312 only if filed after allowance. Answer (C) is incorrect because amendments filed
after the date the issue fee has been paid are no longer permitted under 37 CFR § 1.312. (E) is
wrong because (A) is correct.
