(a) The applicant may submit an inventor's oath or declaration meeting the requirements of § 1.63, § 1.64, or § 1.162 to correct any deficiencies or inaccuracies present in an earlier-filed inventor's oath or declaration. Deficiencies or inaccuracies due to the failure to meet the requirements of § 1.63(b) in an oath or declaration may be corrected with an application data sheet in accordance with § 1.76, except that any correction of inventorship must be pursuant to § 1.48.
(b) A supplemental inventor's oath or declaration under this section must be executed by the person whose inventor’s oath or declaration is being withdrawn, replaced, or otherwise corrected.
(c) The Office will not require a person who has executed an oath or declaration in compliance with 35 U.S.C. 115 and § 1.63 or 1.162 for an application to provide an additional inventor's oath or declaration for the application.
(d) 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 inventor's oath or declaration.

(a) The Office may require, or inventors and applicants may submit, a supplemental oath or declaration meeting the requirements of § 1.63 or § 1.162 to correct any deficiencies or inaccuracies present in the earlier filed oath or declaration.

(1) Deficiencies or inaccuracies relating to all the inventors or applicants (§§ 1.42, 1.43, or § 1.47) may be corrected with a supplemental oath or declaration signed by all the inventors or applicants.
(2) Deficiencies or inaccuracies relating to fewer than all of the inventor(s) or applicant(s) (§§ 1.42, 1.43 or § 1.47) may be corrected with a supplemental oath or declaration identifying the entire inventive entity but signed only by the inventor(s) or applicant(s) to whom the error or deficiency relates.
(3) Deficiencies or inaccuracies due to the failure to meet the requirements of § 1.63(c) (e.g., to correct the omission of a mailing address of an inventor) in an oath or declaration may be corrected with an application data sheet in accordance with § 1.76.
(4) Submission of a supplemental oath or declaration or an application data sheet (§ 1.76), as opposed to who must sign the supplemental oath or declaration or an application data sheet, is governed by § 1.33(a)(2) and paragraph (b) of this section.

(b) A supplemental oath or declaration meeting the requirements of § 1.63 must be filed when a claim is presented for matter originally shown or described but not substantially embraced in the statement of invention or claims originally presented or when an oath or declaration submitted in accordance with § 1.53(f) after the filing of the specification and any required drawings specifically and improperly refers to an amendment which includes new matter. No new matter may be introduced into a nonprovisional application after its filing date even if a supplemental oath or declaration is filed. In proper situations, the oath or declaration here required may be made on information and belief by an applicant other than the inventor.
(c) [Reserved]

Example 1: An application was filed with a declaration under pre-AIA 37 CFR 1.63 executed by inventors A, B, and C. If it is later determined that the citizenship of inventor C was in error, a supplemental declaration identifying inventors A, B, and C may be signed by inventor C alone correcting C’s citizenship.

Example 2: An application was filed with a declaration under pre-AIA 37 CFR 1.63 executed by inventors A, B, and C. If it is later determined that the duty to disclose clause was omitted, a supplemental declaration identifying inventors A, B, and C must be signed by inventors A, B, and C. If separate declarations had been executed by each of the inventors and the duty to disclose clause had been omitted only in the declaration by inventor B, then only inventor B would need to execute a supplemental declaration identifying the entire inventive entity.

Example 3: An application was filed with a declaration under pre-AIA 37 CFR 1.63 executed by inventors A, and B, and the legal representative of deceased inventor C. It is later determined that an error was made in the citizenship of deceased inventor C. A supplemental declaration identifying A, B, and C as the inventors would be required to be signed by the legal representative of deceased inventor C alone correcting C’s citizenship.

Example 4: An application was filed with a declaration under pre-AIA 37 CFR 1.63 executed by inventors A and B. If it is later determined that an error exists in the mailing address of inventor B, the mailing address of inventor B may be corrected by a supplemental declaration identifying the entire inventive entity and signed by inventor B alone, or an application data sheet under 37 CFR 1.76 containing only a change in inventor B’s mailing address.
