602.01(a) Inventor’s Oath or Declaration in Application Filed On or After September 16, 2012 [R-07.2022]

[Editor Note: See MPEP § 602.01(b) for information pertaining to an inventor's oath or declaration in applications filed before September 16, 2012.]

The inventor, or each individual who is a joint inventor of a claimed invention, in an application for patent (other than a provisional application) must execute an oath or declaration directed to the application, except as provided for in 37 CFR 1.64 . See 37 CFR 1.63(a) and 35 U.S.C. 115. An oath or declaration must: (1) identify the inventor or joint inventor executing the oath or declaration by their legal name; (2) identify the application to which it is directed; (3) include a statement the person executing the oath or declaration believes the named inventor or joint inventors to be the original inventor or an original joint inventor of a claimed invention in the application for which the oath or declaration is being submitted; and (4) state that the application was made or authorized to be made by the person executing the oath or declaration. Items (3) and (4) above are requirements of 35 U.S.C. 115(a) and (b).

The requirements that an oath or declaration must identify the inventor or joint inventor executing the oath or declaration by their legal name and identify the application to which it is directed are necessary for the Office to ensure compliance with the requirement of 35 U.S.C. 115(a). Specifically, 35 U.S.C. 115(a) requires that each individual who is the inventor or a joint inventor of a claimed invention in an application for patent has executed an oath or declaration in connection with the application (except as provided for in 35 U.S.C. 115). See MPEP § 602.08(b) for additional information pertaining to inventor names.

Unless such information is supplied in an application data sheet in accordance with 37 CFR 1.76, the oath or declaration must also identify: (1) each inventor by their legal name; (2) a mailing address where the inventor or each joint inventor customarily receives mail; and (3) a residence for each inventor or joint inventor who lives at a location which is different from where the inventor or joint inventor customarily receives mail. See 37 CFR 1.63(b).

For nonprovisional international design applications, 37 CFR 1.1021(d)(3) provides that the requirement in 37 CFR 1.63(b) to identify each inventor by their legal name, mailing address, and residence, if an inventor lives at a location which is different from the mailing address, will be considered satisfied by the presentation of such information in the international design application prior to international registration.

See also MPEP § 602.08(a) for additional details regarding inventor bibliographic information.

If applicant files an application data sheet (ADS) that identifies each inventor by their legal name, in accordance with 37 CFR 1.76, the applicant is not required to name each inventor in a single oath or declaration. This permits each joint inventor to execute an oath or declaration stating only that the joint inventor executing the oath or declaration is an original joint inventor of the claimed invention in the application for which the oath or declaration is being submitted. To be in accordance with 37 CFR 1.76, the application data sheet must be signed in compliance with 37 CFR 1.33(b). An unsigned application data sheet will be treated only as a transmittal letter.

See MPEP § 602.08(c) for the minimum information necessary to identify the application to which an oath or declaration under 37 CFR 1.63 is directed.

An oath or declaration under 37 CFR 1.63 in an application filed on or after September 16, 2012 is no longer required to contain the “reviewed and understands” clause and “duty to disclose” clause of pre-AIA 37 CFR 1.63(b)(2) and (b)(3). However, 37 CFR 1.63 still requires that a person executing an oath or declaration review and understand the contents of the application, and be aware of the duty to disclose under 37 CFR 1.56. See 37 CFR 1.63(c). There is no minimum age for a person to be qualified to execute an oath or declaration, but the person must be competent to execute (i.e., understand) the document that the person is executing.

37 CFR 1.63(e) implements the provisions of 35 U.S.C. 115(e). An assignment may also serve as an oath or declaration required by 37 CFR 1.63 if the assignment: (1) includes the information and statements required under 37 CFR 1.63(a) and (b); and (2) a copy of the assignment is recorded as provided for in 37 CFR part 3. The assignment, including the information and statements required under 37 CFR 1.63(a) and (b), must be executed by the individual who is under the obligation of assignment. Any reference to an oath or declaration includes an assignment as provided for in 37 CFR 1.63(e).

Applicants should be mindful that 37 CFR 3.31 requires a conspicuous indication, such as by use of a check-box on the assignment cover sheet, to alert the Office that an assignment submitted with an application is being submitted for a dual purpose: recording in the assignment database, such as to support a power of attorney, and for use in the application as the inventor’s oath or declaration. Assignments cannot be recorded unless an application number is provided against which the assignment is to be recorded. When filing an application on paper, if an assignment is submitted for recording along with the application, the assignment is separated from the paper application after the application is assigned an application number and is forwarded to the Assignment Recordation Branch for recording in its database. The assignment does not become part of the application file. If the applicant indicates that an assignment-statement is also an oath or declaration, the Office will scan the assignment into the Image File Wrapper (IFW) file for the application before forwarding it to the Assignment Recordation Branch.

For USPTO patent electronic filing system filing of application papers, the USPTO patent electronic filing system does not accept assignments for recording purposes when filing an application. Assignments submitted via the USPTO patent electronic filing system will be made of record in the application, and will not be forwarded to the Assignment Recordation Branch for recordation by the Office. Recording of assignments may only be done electronically in EPAS (Electronic Patent Assignment System). If an applicant files the assignment-statement for recording via EPAS and utilizes the check-box, the Office will place a copy of the assignment-statement in the application file.

With respect to an application naming more than one inventor, any reference to the inventor’s oath or declaration in 37 CFR chapter I means the oaths, declarations, or substitute statements that have been collectively executed by or with respect to all of the joint inventors, unless it is otherwise clear from the context. Thus, any requirement in 37 CFR chapter I for the inventor’s oath or declaration with respect to an application naming more than one inventor is met if an oath or declaration under 37 CFR 1.63, an assignment-statement under 37 CFR 1.63(e), or a substitute statement under 37 CFR 1.64 executed by or with respect to each joint inventor is filed. See 37 CFR 1.63(f).

An oath or declaration under 37 CFR 1.63, including the assignment-statement provided for in 37 CFR 1.63(e), must be executed (i.e., signed) in accordance either with 37 CFR 1.66, or with an acknowledgement that any willful false statement made in such declaration or statement is punishable under 18 U.S.C. 1001 by fine or imprisonment of not more than five (5) years, or both. See 37 CFR 1.63(g) and 35 U.S.C. 115(i). The inventor’s oath or declaration must be executed (i.e., signed) by the inventor or the joint inventors, unless the inventor’s oath or declaration is a substitute statement under 37 CFR 1.64, which must be signed by the applicant, or an assignment-statement under 37 CFR 1.63(e), which must be signed by the inventor who is under the obligation of assignment of the patent application.

See MPEP § 602.08(b) for additional information regarding the execution of the inventor’s oath or declaration.

See 35 U.S.C. 115(g), 37 CFR 1.63(d) and MPEP § 602.05(a) regarding the use of copies of inventor’s oaths or declarations in continuing applications.

35 U.S.C. 115(h)(1) provides that any person making a statement under this section may at any time “withdraw, replace, or otherwise correct the statement at any time.” 37 CFR 1.63(h) provides that an oath or declaration filed at any time pursuant to 35 U.S.C. 115(h)(1) will be placed in the file record of the application or patent, but may not necessarily be reviewed by the Office.

Forms PTO/AIA/01 through PTO/AIA/11 may be used when submitting the inventor’s oath or declaration in an application filed on or after September 16, 2012. These forms and an "AIA Inventor's Oath or Declaration Quick Reference Guide" are available on the USPTO website at www.uspto.gov/PatentForms.

602.01(b) Inventor’s Oath or Declaration in Application Filed Before September 16, 2012 [R-07.2022]

[Editor Note: See MPEP § 602.01(a) for information pertaining to an inventor’s oath or declaration in applications filed on or after September 16, 2012.]

The inventor, or each individual who is a joint inventor of a claimed invention, in an application for patent (other than a provisional application) must execute an oath or declaration directed to the application, except as provided for in pre-AIA 37 CFR 1.64. See pre-AIA 37 CFR 1.63(a) and pre-AIA 35 U.S.C. 115. When joint inventors execute separate oaths or declarations, each oath or declaration should make reference to the fact that the affiant or declarant is a joint inventor together with each of the other inventors indicating them by name. This may be done by stating that the affiant or declarant does verily believe that the affiant or declarant is the original, first and joint inventor together with “A” or “A & B, etc.” as the facts may be.

Pre-AIA 37 CFR 1.63(a) and (b) set forth the basic requirements for an oath or declaration in an application filed before September 16, 2012.

See MPEP § 602.08et seq. for details specific to the required inventor bibliographic information, signature, and name, and to the identification of the application to which the oath or declaration applies.

Unless included in an application data sheet, oaths and declarations must make reference to any foreign application for patent (or inventor’s certificate) for which priority is claimed and any foreign application filed prior to the filing date of an application on which priority is claimed. See pre-AIA 37 CFR 1.63(c)(2).

The applicant is required to recite all foreign applications filed prior to the application on which priority is claimed. It is required to give the foreign application number and name of the country or office in which filed, as well as the filing date of each foreign application to which priority is claimed.

See MPEP § 602.03 for information pertaining to defective oaths or declarations.

Forms PTO/SB/01 through PTO/SB/04 may be used when submitting the inventor’s oath or declaration in an application filed before September 16, 2012, which are available on the USPTO website at www.uspto.gov/patents/apply/forms/forms.

602.01(c) Correction of Inventorship, Name of Inventor, and Order of Names in an Application [R-07.2022]

The Office will issue a filing receipt listing the inventors identified at the time of filing of the application even if the application was filed without an executed oath or declaration. See MPEP § 602.01 for information specific to naming inventorship. Correction of inventorship may be requested under 37 CFR 1.48 or may be obtained by filing a continuing application under 37 CFR 1.53.

See MPEP § 601.01(a), subsection II for information regarding completion of an nonprovisional application subsequent to the filing date pursuant to 37 CFR 1.53(f) (e.g., because the inventor’s oath or declaration was not present on filing date). See MPEP § 601.01(b) for information regarding completion of a provisional application subsequent to the filing date.

Correction of inventorship in an application is permitted by amendment under 35 U.S.C. 116, which is implemented by 37 CFR 1.48.

For requests for correction of inventorship filed under 37 CFR 1.48(a) or (d) on or after September 16, 2012 (without regard to the filing date of the application), see MPEP § 602.01(c)(1).

For requests filed on or after September 16, 2012, under 37 CFR 1.48(f) to correct or update inventor names, or to change the order of inventor names, see MPEP § 602.01(c)(2). Note that requests under 37 CFR 1.48 filed on or after September 16, 2012 will be handled by the Office of Patent Application Processing (OPAP).

For requests for correction of inventorship filed before September 16, 2012 (without regard to the filing date of the application), see MPEP § 602.01(c)(3) in Revision 08.2017 of the Ninth Edition of the MPEP, published in January 2018.

For additional information pertaining to correction of inventorship in applications that name joint inventors, see MPEP § 602.09.

37 CFR 1.48 does not apply to reissue applications as is noted in its title, whether correcting an inventorship error in the patent to be reissued or in the reissue application itself. Where an error in inventorship in a patent is to be corrected via a reissue application, see 37 CFR 1.171- 37 CFR 1.175 and MPEP § 1412.04. Where such an error is to be corrected via a certificate of correction under 37 CFR 1.324, see MPEP § 1481. See 37 CFR 1.48(i) for correction of inventorship in interferences and contested cases before the Patent Trial and Appeal Board.

Although 37 CFR 1.48 does not contain a diligence requirement for filing the request, once an inventorship error is discovered, timeliness requirements under 37 CFR 1.116 and 37 CFR 1.312 apply.

A request under 37 CFR 1.48 will not be required:

(A)Where an application is to issue with the correct inventorship based on the allowed claims even though the application may have been filed with an incorrect inventorship based on the claims as originally submitted; and

(B)Where a court has issued an order under 35 U.S.C. 256 for correction of the inventorship of a patent. Such request should be submitted directly to the Certificate of Correction Division along with form PTO/SB/44 (see MPEP § 1485).

Correction of inventorship may also be obtained by the filing of a continuing application under 37 CFR 1.53 without the need for filing a request under 37 CFR 1.48, although it should be noted that the requirements for a request under 37 CFR 1.48 filed on or after September 16, 2012 are minimal.

35 U.S.C. 120 permits a continuing application to claim the benefit of the filing date of a copending, previously filed, parent application provided there is inventorship overlap between the continuing application and the parent application. If the inventive entity of a continuing application includes an inventor named in the parent application, the inventorship overlap required by 35 U.S.C. 120 is met. However, refiling to change inventorship could result in the loss of a benefit claim if there is no overlap in inventorship between the two applications.

Note that a correction of inventorship may result in the loss of power of attorney. For applications filed on or after September 16, 2012, 37 CFR 1.32(e) provides that if the power of attorney was granted by the originally named inventive entity, and an added inventor pursuant to 37 CFR 1.48 does not provide a power of attorney consistent with the power of attorney granted by the originally named inventive entity, the addition of the inventor results in the loss of that power of attorney upon grant of the 37 CFR 1.48 request. This provision does not preclude a practitioner from acting in a representative capacity pursuant to 37 CFR 1.34, if applicable.

For applications filed on or after September 16, 2012, the inventorship in the continuing application is the inventor or joint inventors specified in the ADS filed before or with the copy of the inventor’s oath or declaration from the earlier-filed application. If an ADS is not filed before or with the copy of the inventor’s oath or declaration, then the inventorship is the inventorship in the copy of the inventor’s oath or declaration from the earlier-filed application, unless accompanied by a statement, signed by a 37 CFR 1.33(b) party, stating the name of each inventor in the continuing application. Any new joint inventor named in the continuing application must execute an inventor’s oath or declaration, except as provided for in 37 CFR 1.64.

602.01(c)(1) Correction of Inventorship in an Application – Request Filed On or After September 16, 2012 [R-01.2024]

[Editor Note: See MPEP § 602.01(c)(3) in Revision 08.2017 of the Ninth Edition of the MPEP, published in January 2018 for information about correction of inventorship for requests filed before September 16, 2012.]

37 CFR 1.48 Correction of inventorship pursuant to 35 U.S.C. 116 or correction of the name or order of names in a patent application, other than a reissue application.

• (a) Nonprovisional application: Any request to correct or change the inventorship once the inventorship has been established under § 1.41 must include:
  • (1) An application data sheet in accordance with § 1.76 that identifies each inventor by his or her legal name; and
  • (2) The processing fee set forth in § 1.17(i).
• (b) Inventor's oath or declaration for added inventor: An oath or declaration as required by § 1.63, or a substitute statement in compliance with § 1.64, will be required for any actual inventor who has not yet executed such an oath or declaration.
• (c) Any request to correct or change the inventorship under paragraph (a) of this section filed after the Office action on the merits has been given or mailed in the application must also be accompanied by the fee set forth in § 1.17(d), unless the request is accompanied by a statement that the request to correct or change the inventorship is due solely to the cancelation of claims in the application.
• (d) Provisional application. Once a cover sheet as prescribed by § 1.51(c)(1) is filed in a provisional application, any request to correct or change the inventorship must include:
  • (1) A request, signed by a party set forth in § 1.33(b), to correct the inventorship that identifies each inventor by his or her legal name; and
  • (2) The processing fee set forth in § 1.17(q).
• (e) Additional information may be required. The Office may require such other information as may be deemed appropriate under the particular circumstances surrounding the correction of inventorship.

*****

Requests for correction of inventorship under 37 CFR 1.48 filed on or after September 16, 2012 are handled by the Office of Patent Application Processing (OPAP).

I. 37 CFR 1.48(a) - NONPROVISIONAL APPLICATION

Under 37 CFR 1.48(a), an applicant may submit a request for correction of inventorship in a nonprovisional patent application once the inventorship has been established. Note that inventorship is established upon the first submission of an application data sheet or inventor’s oath or declaration. See MPEP § 602.08(b), subsection III, for details regarding naming inventorship in an application filed on or after September 16, 2012.

A request to correct the inventorship filed under 37 CFR 1.48(a) should identify the inventorship change and must be accompanied by a signed application data sheet (ADS) including the legal name, residence, and mailing address of the inventor or each actual joint inventor (see 37 CFR 1.76(b)(1)) and the processing fee set forth in 37 CFR 1.17(i). The application data sheet submitted with a request under 37 CFR 1.48(a) must identify the information being changed with underlining for insertions and strike-through or brackets for text removed.

37 CFR 1.48(a) enables an applicant to correct inventorship where an application sets forth improper inventorship as well as where the prosecution of an application results in the need to add or delete one or more inventors (e.g., due to the addition or deletion of claims or an amendment to the claims).

II. 37 CFR 1.48(b) – INVENTOR’S OATH OR DECLARATION FOR ADDED INVENTOR

37 CFR 1.48(b) provides that an oath or declaration as required by 37 CFR 1.63, or a substitute statement in compliance with 37 CFR 1.64, will be required for any actual inventor who has not yet executed such an oath or declaration.

For applications filed on or after September 16, 2012, the oath or declaration required by 37 CFR 1.48(b) must comply with 37 CFR 1.63 in effect for applications filed on or after September 16, 2012. See MPEP § 602.01(a). A substitute statement in compliance with 37 CFR 1.64 is only available for applications filed on or after September 16, 2012. See MPEP § 604 for the requirements for substitute statements.

For applications filed before September 16, 2012, the oath or declaration required by 37 CFR 1.48(b) for an added inventor must comply with pre-AIA 37 CFR 1.63 which remains in effect for applications filed before September 16, 2012. See MPEP § 602.01(b).

III. 37 CFR 1.48(c) – REQUEST FILED AFTER OFFICE ACTION ON THE MERITS

37 CFR 1.48(c) provides that the fee set forth in 37 CFR 1.17(d) (in addition to the processing fee) is required when requests under 37 CFR 1.48 are filed after the Office action on the merits has been given or mailed in the application. However, the fee will not be required when inventors are deleted if the request to correct or change inventorship is accompanied by a statement that the request to correct or change the inventorship is due solely to the cancelation of claims in the application.

IV. 37 CFR 1.48(d) – PROVISIONAL APPLICATION

37 CFR 1.48(d) provides for correcting inventorship in provisional applications. Under 37 CFR 1.41(c), the inventorship of a provisional application is the inventor or joint inventors set forth in the cover sheet as prescribed by 37 CFR 1.51(c)(1). Once a cover sheet is filed in a provisional application, any correction of inventorship must be pursuant to 37 CFR 1.48. If a cover sheet as prescribed by 37 CFR 1.51(c)(1) is not filed during the pendency of a provisional application, the inventorship is the inventor or joint inventors set forth in the application papers filed pursuant 37 CFR 1.53(c), unless the applicant files a paper, including the processing fee set forth in 37 CFR 1.17(q), supplying the name or names of the inventor or joint inventors.

37 CFR 1.48(d) provides a procedure for adding or deleting or correcting or updating the name of an inventor in a provisional application. 37 CFR 1.48(d) requires that the submission include: (1) a request, signed by a party set forth in 37 CFR 1.33(b), to correct the inventorship that identifies each inventor by their legal name; and (2) the fee set forth in 37 CFR 1.17(q). When an inventor is being added, applicants should also file a corrected application data sheet or a new cover sheet providing the residence of all inventors. See 37 CFR 1.51(c). For provisional applications, it may not be necessary to correct the inventorship under 37 CFR 1.48(d) unless there would be no overlap of inventors upon the filing of the nonprovisional application with the correct inventorship. The need to correct the inventorship in any U.S. nonprovisional or provisional application may in part be dependent upon whether a foreign filing under the Paris Convention will occur subsequent to the U.S. filing. See MPEP § 213.

Where an inventorship error in a provisional application is desired to be corrected after expiration of twelve months from the filing date of the provisional application, a request under 37 CFR 1.48(d) may still be filed with OPAP.

V. FORM TO REQUEST CORRECTION OR CHANGE TO INVENTORSHIP

The Office has a form PTO/AIA/40 to request correction in a patent application (other than a reissue application) relating to inventorship, an inventor name, or order of names. The form is reproduced below and is also available on www.uspto.gov/PatentForms.

602.05(a) Oath or Declaration in Continuing Applications Filed On or After September 16, 2012 [R-07.2015]

[Editor Note: See MPEP § 602.05(b) for information regarding oath or declaration in a continuing application filed before September 16, 2012.]

For applications filed on or after September 16, 2012, a continuing application, including a continuation-in-part application, may be filed with a copy of an oath or declaration or substitute statement from the prior nonprovisional application, provided that the oath or declaration is in compliance with 37 CFR 1.63 or the substitute statement is in compliance with 37 CFR 1.64. See 37 CFR 1.63(d)(1). It should be noted that a copy of the inventor’s oath or declaration submitted in a continuing application filed on or after September 16, 2012 must comply with requirements of 35 U.S.C. 115 and 37 CFR 1.63 or 1.64 in effect for applications filed on or after September 16, 2012. For example, the inventor’s oath or declaration must include a statement that the application was made or was authorized to be made by the person executing the oath or declaration. Accordingly, a new inventor’s oath or declaration may need to be filed in a continuing application filed on or after September 16, 2012, where the prior application was filed before September 16, 2012, in order to meet the requirements of 35 U.S.C. 115 and 37 CFR 1.63 (or 1.64) in effect for applications filed on or after September 16, 2012.

For continuing applications filed on or after September 16, 2012 under 37 CFR 1.53(b), the inventorship is the inventor or joint inventors specified in the application data sheet filed before or concurrently with the copy of the inventor’s oath or declaration from the earlier-filed application. If an application data sheet is not filed before or concurrently with the copy of the inventor’s oath or declaration from the earlier-filed application, the inventorship is the inventorship set forth in the copy of the inventor’s oath or declaration from the earlier-filed application, unless it is accompanied by a signed statement pursuant to 37 CFR 1.33(b) that states the name of each inventor in the continuing application. See 37 CFR 1.63(d)(2). Any new joint inventor named in the continuing application must provide an oath or declaration in compliance with 37 CFR 1.63, except as provided in 37 CFR 1.64. See 37 CFR 1.63(d)(3).

602.05(b) Oath or Declaration in Continuing Applications Filed Before September 16, 2012 [R-07.2015]

[Editor Note: See MPEP § 602.05(a) for information regarding oath or declaration in a continuing application filed on or after September 16, 2012.]

A continuation or divisional application filed before September 16, 2012 under 37 CFR 1.53(b) (other than a continuation-in-part (CIP)) may be filed with a copy of the oath or declaration from the prior nonprovisional application. See pre-AIA 37 CFR 1.63(d)(1)(iv).

A continuation or divisional application of a prior application accorded status under pre-AIA 37 CFR 1.47 will be accorded status under pre-AIA 37 CFR 1.47 if a copy of the decision according pre-AIA 37 CFR 1.47 status in the prior application is filed in the continuation or divisional application, unless an oath or declaration signed by all of the inventors is included upon filing the continuation or divisional application. An oath or declaration in an application accorded status under pre-AIA 37 CFR 1.47 is generally not signed by all of the inventors. Accordingly, if a copy of an oath or declaration of a prior application is submitted in a continuation or divisional application filed under 37 CFR 1.53(b) and the copy of the oath or declaration omits the signature of one or more inventors, the Office of Patent Application Processing (OPAP) should send a “Notice to File Missing Parts” requiring the signature of the nonsigning inventor, unless a copy of the decision according status under pre-AIA 37 CFR 1.47 is also included at the time of filing of the continuation or divisional application. If OPAP mails such a Notice, a copy of the decision according status under pre-AIA 37 CFR 1.47, together with a surcharge under 37 CFR 1.16(f) for its late filing, will be an acceptable reply to the Notice. Alternatively, applicant may submit an oath or declaration signed by the previously nonsigning inventor together with the surcharge set forth in 37 CFR 1.16(f) in reply to the Notice.

If an inventor named in a prior application is not an inventor in a continuation or divisional application filed under 37 CFR 1.53(b), the continuation or divisional application may either be filed (A) with a copy of an oath or declaration from a prior application and a statement requesting the deletion of the name or names of the person or persons who are not inventors of the invention being claimed in the continuation or divisional application (see pre-AIA 37 CFR 1.63(d)), or (B) with a newly executed oath or declaration naming the correct inventive entity. If an inventor named in a prior application is not an inventor in a continuation or divisional application filed under 37 CFR 1.53(d) (continued prosecution design application), the request for filing the continuation or divisional application must be accompanied by a statement requesting the deletion of the name or names of the person or persons who are not inventors of the invention being claimed in the continuation or divisional application (see 37 CFR 1.53(d)(4)).

A continuation or divisional application filed under 37 CFR 1.53(b) of a prior application in which a petition (or request) under 37 CFR 1.48 to add an inventor was filed should be filed with a copy of the executed declaration naming the correct inventive entity from the prior application or a newly executed declaration naming the correct inventive entity. A copy of any decision under 37 CFR 1.48 from the prior application is not required to be filed in the continuation or divisional application. See MPEP § 602.01(c)(3) in Revision 08.2017 of the Ninth Edition of the MPEP, published in January 2018, for the language of pre-AIA 37 CFR 1.48.

602.08(a) Inventor Bibliographic Information [R-10.2019]

For applications filed on or after September 16, 2012, the citizenship of the inventor is no longer required by 35 U.S.C. 115 or 37 CFR 1.63.

For nonprovisional applications filed before September 16, 2012, pre-AIA 35 U.S.C. 115 requires the inventor(s) to state his or her citizenship. Where an inventor is not a citizen of any country, a statement to this effect is accepted as satisfying the statutory requirement, but a statement as to citizenship applied for or first papers taken out looking to future citizenship in this (or any other) country does not meet the requirement.

Each inventor’s place of residence, that is, the city and either state or foreign country, is required to be included in the oath or declaration in a nonprovisional application for compliance with 37 CFR 1.63 unless it is included in an application data sheet (37 CFR 1.76). In the case of an inventor who is in one of the U.S. Armed Services, a statement to that effect is sufficient as to residence. For change of residence, see MPEP § 719.02. Each inventor’s residence must be included on the cover sheet for a provisional application unless it is included in an application data sheet (37 CFR 1.76).

If only a mailing address where the inventor customarily receives mail is provided, the Office will presume that the inventor’s residence is the city and either state or foreign country of the mailing address. If the inventor lives at a location which is different from the inventor’s mailing address, the inventor’s residence (city and either state or foreign country) must be included in the inventor’s oath or declaration or an application data sheet.

Each inventor’s mailing or post office address is required to be supplied on the oath or declaration, if not stated in an application data sheet. See 37 CFR 1.63(b), pre-AIA 37 CFR 1.63(c), and 37 CFR 1.76. If the mailing address of any inventor has been omitted, OPAP will notify applicant of the omission and require the omitted mailing address in response to the notice.

The inventor’s mailing address means that address at which he or she customarily receives his or her mail, even if it is not the main mailing address of the inventor. Either the inventor’s home or business address is acceptable as the mailing address. A post office box is also acceptable. The mailing address should include the ZIP Code designation. The object of requiring each inventor’s mailing address is to enable the Office to communicate directly with the inventor if desired; hence, the address of the attorney with instruction to send communications to the inventor in care of the attorney is not sufficient.

In situations where an inventor does not execute the oath or declaration and the inventor is not deceased or legally incapacitated, such as in an application filed on or after September 16, 2012 in which a substitute statement under 37 CFR 1.64 is filed, the inventor’s most recent home address must be given to enable the Office to communicate directly with the inventor as necessary.

602.08(b) Inventor Signature and Name [R-01.2024]

United States patent applications which have not been prepared and executed in accordance with the requirements of Title 35 of the United States Code and Title 37 of the Code of Federal Regulations may be abandoned. Although the statute and the rules have been in existence for many years, the Office continues to receive a number of applications which have been improperly executed and/or filed. Since the improper execution and/or filing of patent applications can ultimately result in a loss of rights, it is appropriate to emphasize the importance of proper execution and filing.

There is no requirement that a signature be made in any particular manner. See MPEP § 402.03. It is permissible for an applicant to use a title of nobility or other title, such as “Dr.”, in connection with their signature. The title will not appear in the printed patent. If applicant signs their name using non-English characters, then such a signature will be accepted. If the applicant is unable to write, their mark as affixed to the oath or declaration must be attested to by a witness. In the case of the oath, the notary’s signature to the jurat is sufficient to authenticate the mark. See MPEP § 602.

Applications filed through the USPTO patent electronic filing system must also contain an oath or declaration personally signed by the inventor.

It is improper for an applicant to sign an oath or declaration which is not attached to or does not identify the application (e.g., a specification and drawings) to which it is directed.

Attached does not necessarily mean that all the papers must be literally fastened. It is sufficient that the specification, including the claims, and the oath or declaration are physically located together at the time of execution. Physical connection is not required. Copies of declarations are encouraged. See MPEP § 502.01, § 502.02, § 602, and § 602.05(a).

An oath or declaration under 37 CFR 1.63 by each actual inventor must be presented. Each inventor need not execute the same oath or declaration. For nonprovisional international design applications, see also 37 CFR 1.1021(d) and 1.1067. For applications filed before September 16, 2012, each oath or declaration executed by an inventor must contain a complete listing of all inventors so as to clearly indicate what each inventor believes to be the appropriate inventive entity. Where individual declarations are executed, they must be submitted as individual declarations rather than combined into one declaration (by combining the signature pages).

The provisions of 35 U.S.C. 363 for filing an international application under the Patent Cooperation Treaty (PCT) which designates the United States and thereby has the effect of a regularly filed United States national application, except as provided in pre-AIA 35 U.S.C. 102(e), are somewhat different than the provisions of 35 U.S.C. 111. The oath or declaration requirements for an international application before the Patent and Trademark Office are set forth in 35 U.S.C. 371(c)(4) and 37 CFR 1.497.

37 CFR 1.52(c) states that “[i]nterlineation, erasure, cancellation, or other alteration of the application papers may be made before or after the signing of the inventor's oath or declaration referring to those application papers, provided that the statements in the inventor's oath or declaration pursuant to § 1.63 remain applicable to those application papers. A substitute specification (§ 1.125) may be required if the application papers do not comply with paragraphs (a) and (b) of this section.”

An inventor is not required to re-execute a new inventor’s oath or declaration after alteration of the application papers provided that the changes are minor, for example, correction of typographical errors, grammatical problems, and clarifying sentences. If the changes would amount to the introduction of new matter had the change been made to a filed application, however, then the inventor should execute a new oath or declaration after reviewing the amended application. The rule permits alterations to the specification without the inventor re-executing an oath or declaration only where the statements in the executed declaration remain applicable. Additionally, an inventor must before executing the oath or declaration (i) review and understand the contents of the application; and (ii) be aware of their duty of disclosure. See 37 CFR 1.63(c). If the changes made to the specification before an application is filed result in substantial alterations to the application, then an inventor may not understand the contents of the application or be aware of their duty to disclose information relating to the substantial alteration.

The signing and execution by the applicant of oaths or declarations in certain continuation or divisional applications may be omitted. See MPEP § 201.06, § 201.07, and § 602.05(a). For the signature on a reply, see MPEP §§ 714.01(a), 714.01(c), and 714.01(d).

The inventor, or each individual who is a joint inventor of a claimed invention, in an application for patent must execute an oath or declaration directed to the application, except as provided under 37 CFR 1.64. Only inventors can execute an oath or declaration under 37 CFR 1.63. The applicant for patent may execute a substitute statement under 37 CFR 1.64 in lieu of an oath or declaration under the permitted circumstances. For information on the execution of a substitute statement, see MPEP § 604.

The oath or declaration required by pre-AIA 35 U.S.C. 115 must be signed by all of the actual inventors, except under limited circumstances. 35 U.S.C. 116 provides that joint inventors can sign on behalf of an inventor who cannot be reached or refuses to join. See MPEP § 409.03(a). 35 U.S.C. 117 provides that the legal representative of a deceased or incapacitated inventor can sign on behalf of the inventor. If a legal representative executes an oath or declaration on behalf of a deceased inventor, the legal representative must state that the person is a legal representative and provide the citizenship, residence, and mailing address of the legal representative. See pre-AIA 37 CFR 1.64 and MPEP § 409.01(b). Pre-AIA 35 U.S.C. 118 provides that a party with proprietary interest in the invention claimed in an application can sign on behalf of the inventor, if the inventor cannot be reached or refuses to join in the filing of the application. See MPEP § 409.03(b) and § 409.03(f). The oath or declaration may not be signed by an attorney on behalf of the inventor, even if the attorney has been given a power of attorney to do so. Opinion of Hon. Edward Bates, 10 Op. Atty. Gen. 137 (1861). See also Staeger v. Commissioner of Patents and Trademarks, 189 USPQ 272 (D.D.C. 1976) and In re Striker, 182 USPQ 507 (PTO Solicitor 1973) (In each case, an oath or declaration signed by the attorney on behalf of the inventor was defective because the attorney did not have a proprietary interest in the invention.).

For nonprovisional applications filed on or after September 16, 2012, 37 CFR 1.63 requires the identification of the inventor by his or her legal name. 37 CFR 1.63(a)(1) simplifies the requirement for the inventor’s name to be his or her name and no longer refers to a family or given name. The requirement for an inventor’s legal name is sufficient, given that individuals do not always have both a family name and a given name, or have varying understandings of what a “given” name requires.

For nonprovisional applications filed before September 16, 2012, pre-AIA 37 CFR 1.63(a)(2) requires that each inventor be identified by full name, including the family name, and at least one given name without abbreviation together with any other given name or initial in the oath or declaration. For example, if the applicant's full name is “John Paul Doe,” either “John P. Doe” or “J. Paul Doe” is acceptable. A situation may arise where an inventor’s full given name is a singular letter, or is a plurality of singular letters. For example, an inventor’s full given name may be “J. Doe” or “J.P. Doe,” i.e., the “J” and the “P” are not initials. In such a situation, identifying the inventor by his or her family name and the singular letter(s) is acceptable, since that is the inventor’s full given name. In order to avoid an objection under 37 CFR 1.63(a)(2), applicant should point out in the oath or declaration that the singular lettering set forth is the inventor’s given name. A statement to this effect, accompanying the filing of the oath or declaration, will also be acceptable.

In an application where the name is typewritten with a middle name or initial, but the signature does not contain such middle name or initial, the typewritten version of the name will be used as the inventor’s name for the purposes of the application and any patent that may issue from the application. No objection should be made in this instance, since the inventor’s signature may differ from their legal name. Any request to have the name of the inventor or a joint inventor in a nonprovisional application corrected or updated, including correction of a typographical or transliteration error in the spelling of an inventor’s name, must be by way of a request under 37 CFR 1.48(f). A request under 37 CFR 1.48(f) must include (1) an application data sheet in accordance with 37 CFR 1.76 that identifies each inventor by their legal name, and (2) the processing fee set forth in 37 CFR 1.17(i). Requests under 37 CFR 1.48(f) filed on or after September 16, 2012, are treated by the Office of Patent Application Processing (OPAP). If the request complies with 37 CFR 1.48(f), OPAP will correct the Office records and send a corrected filing receipt.

If the error in the inventor’s name is not detected until after the payment of the issue fee, because amendments are not permitted after the payment of the issue fee, either (A) the application must be withdrawn from issue under 37 CFR 1.313(c)(2) and a request under 37 CFR 1.48(f) to correct the inventor’s name submitted with a request for continued examination (RCE) under 37 CFR 1.114, or (B) a certificate of correction, along with a petition under 37 CFR 1.182, must be filed after the patent issues requesting correction of inventor’s name.

Any request to correct or change inventorship, or correct or update the name of the inventor or a joint inventor, in a provisional application must be made pursuant to 37 CFR 1.48(d). 37 CFR 1.48(d) requires a request signed by a party set forth in 37 CFR 1.33(b), that identifies each inventor by their legal name, and the processing fee set forth in 37 CFR 1.17(q). OPAP treats requests under 37 CFR 1.48(d) and will correct the Office records and send a corrected filing receipt if the request complies with 37 CFR 1.48(d).

When an inventor’s name has been changed after the nonprovisional application has been filed and the inventor desires to change their name on the application, they must submit a request under 37 CFR 1.48(f), including an application data sheet in accordance with 37 CFR 1.76, that identifies each inventor by their legal name and the processing fee set forth in 37 CFR 1.17(i). The corrected application data sheet must identify the information being changed as required by 37 CFR 1.76(c)(2). The Office of Patent Application Processing (OPAP) treats requests under 37 CFR 1.48(f) and will correct the Office records and send a corrected filing receipt if the request complies with 37 CFR 1.48(f).Since amendments are not permitted after the payment of the issue fee (37 CFR 1.312), a request under 37 CFR 1.48(f) to change the name of the inventor cannot be granted if filed after the payment of the issue fee.

If the application is assigned, applicant should submit a corrected assignment document along with a cover sheet and the recording fee as set forth in 37 CFR 1.21(h) to the Assignment Recordation Branch for a change in the assignment record.

For applications filed on or after September 16, 2012, the order of names of joint patentees in the heading of the patent is taken from the order in which the names appear in the application data sheet if submitted before or with the inventor’s oath or declaration. For applications filed before September 16, 2012, the order of names of joint patentees in the heading of the patent is taken from the order in which the typewritten names appear in the original oath or declaration. Care should therefore be exercised in selecting the preferred order of the typewritten names of the joint inventors, before filing, as requests for subsequent shifting of the names would entail changing numerous records in the Office.

Because the particular order in which the names appear is of no consequence insofar as the legal rights of the joint inventors are concerned, no changes will be made except when a request under 37 CFR 1.48(f) (filed on or after September 16, 2012) is granted. It is suggested that all typewritten and signed names appearing in the application papers should be in the same order as the typewritten names in the oath or declaration. The Office of Patent Application Processing (OPAP) treats requests under 37 CFR 1.48(f) and if the request is granted OPAP will change the order of the names in the Office computer records and send a corrected filing receipt. Because a change to the order of names of joint inventors is an amendment to the application and amendments are not permitted after the payment of the issue fee (37 CFR 1.312), a request under 37 CFR 1.48(f) to change the order of the names of joint inventors cannot be granted if filed after the payment of the issue fee.

In those instances where the joint inventors file separate oaths or declarations in an application filed before September 16, 2012, the order of names is taken from the order in which the several oaths or declarations appear in the application papers unless a different order is requested at the time of filing or a request under 37 CFR 1.48(f) is granted. For applications filed on or after September 16, 2012, the order of inventors is taken from an application data sheet in accordance with 37 CFR 1.76 if filed before or with the inventor’s oath or declaration unless a request under 37 CFR 1.48(f) is granted. A request under 37 CFR 1.48(f) may be filed on or after September 16, 2012 to change the order of the names of joint inventors in a nonprovisional application regardless of the filing date of the application.

602.08(c) Identification of Application [R-07.2015]

37 CFR 1.63 requires that an oath or declaration identify the application (e.g., specification and drawings) to which it is directed.

The following combination of information supplied in an oath or declaration filed on the application filing date with a specification are acceptable as minimums for identifying the application and compliance with any one of the items below will be accepted as complying with the identification requirement of 37 CFR 1.63:

• (A) name of inventor(s), and reference to an attached specification or application which is both attached to the oath or declaration at the time of execution and submitted with the oath or declaration on filing;

• (B) name of inventor(s), and attorney docket number which was on the specification as filed; or

• (C) name of inventor(s), and title of the invention which was on the specification as filed.

Filing dates are granted on applications filed without an inventor’s oath or declaration in compliance with 37 CFR 1.63. The following combinations of information supplied in an oath or declaration filed after the filing date of the application are acceptable as minimums for identifying the application and compliance with any one of the items below will be accepted as complying with the identification requirement of 37 CFR 1.63:

• (A) application number (consisting of the series code and the serial number, e.g., 08/123,456);

• (B) serial number and filing date;

• (C) international application number of an international application;
• (D) international registration number of an international design application;

• (E) attorney docket number which was on the specification as filed;

• (F) title of the invention which was on the specification as filed and reference to an attached specification or application which is both attached to the oath or declaration at the time of execution and submitted with the oath or declaration; or

• (G) title of the invention which was on the specification as filed and accompanied by a cover letter accurately identifying the application for which it was intended by either the application number (consisting of the series code and the serial number, e.g., 08/123,456), or serial number and filing date. Absent any statement(s) to the contrary, it will be presumed that the application filed in the USPTO is the application which the inventor(s) executed by signing the oath or declaration.

Any specification that is filed attached to an oath or declaration on a date later than the application filing date will not be compared with the specification submitted on filing. Absent any statement(s) to the contrary, the “attached” specification will be presumed to be a copy of the specification and any amendments thereto, which were filed in the USPTO in order to obtain a filing date for the application.

Any variance from the above guidelines will only be considered upon the filing of a petition for waiver of the rules under 37 CFR 1.183 accompanied by a petition fee (37 CFR 1.17(f)).

Further an oath or declaration attached to a cover letter referencing an incorrect application may not become associated with the correct application and, therefore, could result in the abandonment of the correct application.

See MPEP § 1896 for the identification requirements for a declaration filed in a U.S. national stage application filed under 35 U.S.C. 371.
