Oath or Declaration by Inventors Required for Nonprovisional International Design Applications
Note:
Each actual inventor must sign an oath or declaration, with individual declarations required for each inventor.

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).

Substitute Specification Required for Non-Compliant Application Papers
Note:
A substitute specification must be provided if the application papers do not meet specific requirements.

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.”

Legal Name Requirement for Inventors Sufficient
Note:
The rule states that an inventor's legal name is sufficient for nonprovisional applications filed on or after September 16, 2012, acknowledging that individuals may not have both a family and given name.

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.

Inventor Given Name Can Be Singular Letter
Note:
An inventor’s given name can be a single letter, and must be identified with the family name in the oath or declaration.

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.

Inventor Signature Requirement for Patent Applications
Note:
Patent applications must include proper inventor signatures and comply with Title 35 and Title 37 requirements to avoid abandonment.

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.

Inventor Signature Requirements
Note:
The rule outlines the acceptable methods for an inventor to sign their patent application, including using titles and non-English characters, and provides procedures for signing by mark if unable to write.

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.

Each inventor must be identified by full name, including family and at least one given name without abbreviation in the oath or declaration for nonprovisional applications filed before September 16, 2012.

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.

Typewritten Name Used If Signature Missing Middle Initial
Note:
If an inventor’s name includes a middle initial in the application but not in the signature, the typewritten version will be used for the patent.

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.

Order of Joint Patentees in Patent Heading
Note:
For applications filed on or after September 16, 2012, the order of joint patentees' names in the patent heading is determined by the order in which they appear in the application data sheet.

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.

Joint Inventor Name Order Must Match Oath/Declaration
Note:
The order of joint inventor names in application papers must match the order in the oath or declaration, unless a specific request is granted after September 15, 2012.

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.

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.

Request for Correcting Inventor's Name Must Be by 37 CFR 1.48(f)
Note:
A request to correct an inventor’s name in a nonprovisional application must be made through a specific request under 37 CFR 1.48(f).

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.

Request to Change Joint Inventor Names
Note:
The Office of Patent Application Processing will change the order of joint inventor names in the records if a request under 37 CFR 1.48(f) is granted.

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.

Oath/Declaration Requirement for Each Inventor
Note:
Each actual inventor must submit an oath or declaration under 37 CFR 1.63, with individual declarations required for nonprovisional international design applications.

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).

Inventor Oath/Declaration for Specification Changes
Note:
An inventor must review and understand the application before signing an oath or declaration, and may alter the specification without re-executing the oath if changes are minor.

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.

Inventor’s Legal Name Required for Nonprovisional Applications Filed On Or After September 16, 2012
Note:
The rule requires that the inventor's name on nonprovisional applications filed after September 16, 2012, be their legal name.

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.

Singular Letter as Given Name Requirement
Note:
Applicant must identify an inventor with a singular letter as their given name in the oath or declaration to avoid objection under 37 CFR 1.63(a)(2).

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.

Minor Specification Changes Do Not Require New Oath
Note:
An inventor does not need to re-execute an oath if the changes are minor, such as correcting typographical errors or clarifying sentences. A new oath is required only if substantial alterations introduce new matter.

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.

An attorney may not sign an oath or declaration on behalf of an inventor, even if the attorney has a power of attorney.

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.

Inventor Name Requirement for Nonprovisional Applications Filed Before September 16, 2012
Note:
The inventor must be identified by full name, including the family name and at least one given name without abbreviation.

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.
