Application Data Sheet Required for Postponed Oath/Declaration
Note:
Applicant must submit an application data sheet identifying inventors by legal name, mailing address, and residence if different to postpone filing the inventor’s oath or declaration.

The filing of the inventor’s oath or declaration may be postponed until the application is otherwise in condition for allowance if applicant submits an application data sheet in accordance with 37 CFR 1.76 identifying each inventor by his or her legal name, the mailing address where each inventor customarily receives mail, and the residence of each inventor, if the inventor lives at a location which is different from where the inventor customarily receives mail. See 37 CFR 1.495(c)(3). Postponement of the filing of the inventor’s oath or declaration pursuant to 37 CFR 1.495(c) will not postpone the requirement to pay the surcharge fee under 37 CFR 1.492(h) for filing the inventor’s oath or declaration after the date of commencement. As discussed in MPEP § 706.07(h), subsection I, notwithstanding 37 CFR 1.495(c)(3) permitting postponement, all required inventor’s oaths or declarations (or substitute statements) must be filed prior to or with a request for continued examination (RCE) under 37 CFR 1.114. Early national stage entry under 35 U.S.C. 371(f) also requires the submission of the oath or declaration required by 35 U.S.C. 371(c)(4) and submission also may not be postponed in this situation.

Correcting Inventorship for PCT National Stage
Note:
Follow procedures in pre-AIA 37 CFR 1.497(d) and 37 CFR 1.48(a) to correct inventorship before entering an international application into the U.S. national phase.

The inventorship of an international application entering the national stage under 35 U.S.C. 371 having an international filing date before September 16, 2012 is that inventorship set forth in the international application, which includes any changes effected under PCT Rule 92bis. See pre-AIA 37 CFR 1.41(a)(4). Accordingly, an oath or declaration that names an inventive entity different than that set forth in the international application will not be accepted for purposes of entering the U.S. national phase unless the inventorship is corrected. See the procedures set forth in pre-AIA 37 CFR 1.497(d) and 37 CFR 1.48(a) for correcting inventorship. If an inventor refuses to execute the oath or declaration or cannot be found or reached after diligent effort, applicant may file an oath or declaration and a petition in accordance with pre-AIA 37 CFR 1.47. Similarly, where an inventor is deceased or legally incapacitated, an oath or declaration may be made in accordance with the provisions of pre-AIA 37 CFR 1.42 or 1.43. See pre-AIA 37 CFR 1.497(b).

    • (1) There was a change in the international filing date pursuant to PCT Rule 20.5(c) after the declaration was executed; or
    • (2) A change in the inventive entity was effected under PCT Rule 92bis after the declaration was executed and no declaration which sets forth and is executed by the inventive entity as so changed has been filed in the application.
  • (g) If a priority claim has been corrected or added pursuant to PCT Rule 26 bis during the international stage after the declaration of inventorship was executed in the international application under PCT Rule 4.17(iv), applicant will be required to submit either a new oath or declaration or an application data sheet as set forth in § 1.76 correctly identifying the application upon which priority is claimed.

Inventorship Set by International Application
Note:
The inventorship for an international application entering the U.S. national stage before September 16, 2012, must match that set forth in the original international application, including any changes made under PCT Rule 92bis.

The inventorship of an international application entering the national stage under 35 U.S.C. 371 having an international filing date before September 16, 2012 is that inventorship set forth in the international application, which includes any changes effected under PCT Rule 92bis. See pre-AIA 37 CFR 1.41(a)(4). Accordingly, an oath or declaration that names an inventive entity different than that set forth in the international application will not be accepted for purposes of entering the U.S. national phase unless the inventorship is corrected. See the procedures set forth in pre-AIA 37 CFR 1.497(d) and 37 CFR 1.48(a) for correcting inventorship. If an inventor refuses to execute the oath or declaration or cannot be found or reached after diligent effort, applicant may file an oath or declaration and a petition in accordance with pre-AIA 37 CFR 1.47. Similarly, where an inventor is deceased or legally incapacitated, an oath or declaration may be made in accordance with the provisions of pre-AIA 37 CFR 1.42 or 1.43. See pre-AIA 37 CFR 1.497(b).

The filing of the inventor’s oath or declaration may be postponed until the application is otherwise in condition for allowance if applicant submits an application data sheet in accordance with 37 CFR 1.76 identifying each inventor by his or her legal name, the mailing address where each inventor customarily receives mail, and the residence of each inventor, if the inventor lives at a location which is different from where the inventor customarily receives mail. See 37 CFR 1.495(c)(3). Postponement of the filing of the inventor’s oath or declaration pursuant to 37 CFR 1.495(c) will not postpone the requirement to pay the surcharge fee under 37 CFR 1.492(h) for filing the inventor’s oath or declaration after the date of commencement.

Requirement for Inventor Declaration in National Stage
Note:
A new oath or declaration is required if inventorship changes after a PCT Rule 4.17(iv) declaration was submitted within the international phase time limits.

In general, the requirement for an oath or declaration in compliance with 37 CFR 1.497(a) – (b) will have been previously satisfied if a declaration in compliance with PCT Rule 4.17(iv) executed by all the inventors was submitted within the time limits provided in PCT Rule 26ter.1 in the international phase. However, if the inventorship was changed in the international application under PCT Rule 92bis such that the inventorship identified in the PCT Rule 4.17(iv) declaration no longer corresponds to that of the international application (see pre-AIA 37 CFR 1.41(a)(4)), then a new oath or declaration in accordance with 37 CFR 1.497(a) – (b) may be required to enter the national stage. See pre-AIA 37 CFR 1.497(f)(2). Similarly, a new oath or declaration in compliance with 37 CFR 1.497(a) – (b) is required where the PCT Rule 4.17(iv) declaration was executed prior to a change in the international filing date pursuant to PCT Rule 20.5(c). See pre-AIA 37 CFR 1.497(f)(1). In addition, where a priority claim has been corrected or added pursuant to PCT Rule 26.2bis after execution of the PCT Rule 4.17(iv) declaration, then a supplemental oath or declaration, or an application data sheet, identifying the correct priority claim will be required.

Oath or Declaration Required for National Stage Entry
Note:
Applicants must file an oath or declaration within the national stage to avoid abandonment of their application.

Applicants entering the national stage under 35 U.S.C. 371 for an international application having an international filing date prior to September 16, 2012 are required to file an oath or declaration of the inventor in accordance with pre-AIA 37 CFR 1.497(a) and (b). If the basic national fee and copy of the international application have been received by the expiration of 30 months from the priority date, but the required oath or declaration has not been filed, the Office will send applicant a Notification of Missing Requirements (Form PCT/DO/EO/905) setting a time period to correct any missing or defective requirements and to submit the surcharge fee required under 37 CFR 1.492(h) unless previously paid.

Oath or Declaration When Inventor Refuses or Cannot Be Reached
Note:
If an inventor refuses to sign the oath or cannot be located after efforts, the applicant can submit a new oath and petition according to pre-AIA 37 CFR 1.47.

The inventorship of an international application entering the national stage under 35 U.S.C. 371 having an international filing date before September 16, 2012 is that inventorship set forth in the international application, which includes any changes effected under PCT Rule 92bis. See pre-AIA 37 CFR 1.41(a)(4). Accordingly, an oath or declaration that names an inventive entity different than that set forth in the international application will not be accepted for purposes of entering the U.S. national phase unless the inventorship is corrected. See the procedures set forth in pre-AIA 37 CFR 1.497(d) and 37 CFR 1.48(a) for correcting inventorship. If an inventor refuses to execute the oath or declaration or cannot be found or reached after diligent effort, applicant may file an oath or declaration and a petition in accordance with pre-AIA 37 CFR 1.47. Similarly, where an inventor is deceased or legally incapacitated, an oath or declaration may be made in accordance with the provisions of pre-AIA 37 CFR 1.42 or 1.43. See pre-AIA 37 CFR 1.497(b).

Oath or Declaration Requirement Varies by International Filing Date
Note:
The requirement for an inventor’s oath or declaration in a national stage application differs based on the international filing date of the application.

Pursuant to 35 U.S.C. 371(c)(4), the applicant for a national stage application is required to file an oath or declaration of the inventor (or other person authorized under 35 U.S.C. chapter 11) complying with the requirements of 35 U.S.C. 115 and with regulations prescribed for oaths or declarations of applicants. The America Invents Act (AIA) amended 35 U.S.C. 115 with effect for applications filed on or after September 16, 2012. As a consequence of this change, the oath or declaration requirements for a national stage application differ depending on the international filing date of the national stage application, as set forth below.

New Oath Required for Changed International Filing Date
Note:
A new oath or declaration in compliance with 37 CFR 1.497(a)-(b) is required if the international filing date changes under PCT Rule 20.5(c).

In general, the requirement for an oath or declaration in compliance with 37 CFR 1.497(a) – (b) will have been previously satisfied if a declaration in compliance with PCT Rule 4.17(iv) executed by all the inventors was submitted within the time limits provided in PCT Rule 26ter.1 in the international phase. However, if the inventorship was changed in the international application under PCT Rule 92bis such that the inventorship identified in the PCT Rule 4.17(iv) declaration no longer corresponds to that of the international application (see pre-AIA 37 CFR 1.41(a)(4)), then a new oath or declaration in accordance with 37 CFR 1.497(a) – (b) may be required to enter the national stage. See pre-AIA 37 CFR 1.497(f)(2). Similarly, a new oath or declaration in compliance with 37 CFR 1.497(a) – (b) is required where the PCT Rule 4.17(iv) declaration was executed prior to a change in the international filing date pursuant to PCT Rule 20.5(c). See pre-AIA 37 CFR 1.497(f)(1). In addition, where a priority claim has been corrected or added pursuant to PCT Rule 26.2bis after execution of the PCT Rule 4.17(iv) declaration, then a supplemental oath or declaration, or an application data sheet, identifying the correct priority claim will be required. See pre-AIA 37 CFR 1.497(g).

Inventorship May Be Corrected Under Procedure Set Forth in 37 CFR 1.48(a)
Note:
This rule permits the correction of inventorship under the specified procedure for applications filed on or after September 16, 2012.

The inventor’s oath or declaration must be executed by each inventor, except as provided under 37 CFR 1.64. The inventorship of an international application entering the national stage under 35 U.S.C. 371 having an international filing date on or after September 16, 2012, is the inventor or joint inventors set forth in an application data sheet in accordance with 37 CFR 1.76 accompanying the initial submission under 35 U.S.C. 371. If the initial submission under 35 U.S.C. 371 is not accompanied by an application data sheet in accordance with 37 CFR 1.76, the inventorship is the inventor or joint inventors set forth in the international application, which includes any change effected under PCT Rule 92bis. See 37 CFR 1.41(e). Inventorship may be corrected under the procedure set forth in 37 CFR 1.48(a). The name of an inventor may be corrected or updated under the procedure set forth in 37 CFR 1.48(f).

An oath or declaration satisfying the requirements of pre-AIA 37 CFR 1.497(a) – (b) will be sufficient for the purposes of entering the U.S. national phase. However, if the oath or declaration fails to also comply with the additional requirements for oaths and declarations set forth in 37 CFR 1.63, applicants will need to submit a supplemental oath or declaration, or an application data sheet where permitted under 37 CFR 1.63(c), to correct the deficiency.

Inventorship Must Match International Application
Note:
The inventorship in a U.S. national phase application must match the international application, including any changes under PCT Rule 92bis.

The inventorship of an international application entering the national stage under 35 U.S.C. 371 having an international filing date before September 16, 2012 is that inventorship set forth in the international application, which includes any changes effected under PCT Rule 92bis. See pre-AIA 37 CFR 1.41(a)(4). Accordingly, an oath or declaration that names an inventive entity different than that set forth in the international application will not be accepted for purposes of entering the U.S. national phase unless the inventorship is corrected. See the procedures set forth in pre-AIA 37 CFR 1.497(d) and 37 CFR 1.48(a) for correcting inventorship. If an inventor refuses to execute the oath or declaration or cannot be found or reached after diligent effort, applicant may file an oath or declaration and a petition in accordance with pre-AIA 37 CFR 1.47. Similarly, where an inventor is deceased or legally incapacitated, an oath or declaration may be made in accordance with the provisions of pre-AIA 37 CFR 1.42 or 1.43. See pre-AIA 37 CFR 1.497(b).
