 325 Establishing Right of Assignee To Take Action in Application Filed On or After
 September 16, 2012 [R-01.2024]
 

 [Editor Note: See MPEP § 324 for establishing the right of assignee to take
 action in an application filed before September 16, 2012.] 

 
 37 CFR 3.71 Prosecution by assignee. 

 [Editor Note: Applicable to patent applications under 35 U.S.C.
 111(a) , 363 , or 385 
 on or after September 16, 2012. See pre-AIA 37 CFR 3.71 for the rule
 otherwise applicable.] 

 
 (a) Patents—conducting of prosecution. One or more assignees as
 defined in paragraph (b) of this section may conduct prosecution of a national
 patent application as the applicant under § 1.46 of this title, or conduct
 prosecution of a supplemental examination or reexamination proceeding, to the
 exclusion of the inventor or previous applicant or patent owner. Conflicts between
 purported assignees are handled in accordance with § 3.73(c)(3).
 

 (b) Patents—assignee(s) who can prosecute. The assignee(s) who may
 conduct either the prosecution of a national application for patent as the
 applicant under § 1.46 of this title or a supplemental examination or
 reexamination proceeding are:
 
 (1) A single assignee. An assignee of the entire right, title
 and interest in the application or patent, or
 

 (2) Partial assignee(s) together or with inventor(s). All
 partial assignees, or all partial assignees and inventors who have not
 assigned their right, title and interest in the application or patent, who
 together own the entire right, title and interest in the application or
 patent. A partial assignee is any assignee of record having less than the
 entire right, title and interest in the application or patent. The word
 "assignee" as used in this chapter means with respect to patent matters the
 single assignee of the entire right, title and interest in the application
 or patent if there is such a single assignee, or all of the partial
 assignees, or all of the partial assignee and inventors who have not
 assigned their interest in the application or patent, who together own the
 entire right, title and interest in the application or patent.
 

 
 

 (c) Patents—Becoming of record. An assignee becomes of record as
 the applicant in a national patent application under § 1.46 of this title, and in
 a supplemental examination or reexamination proceeding, by filing a statement in
 compliance with § 3.73(c) that is signed by a party who is authorized to act on
 behalf of the assignee.
 

 (d) Trademarks. The assignee of a trademark application or
 registration may prosecute a trademark application, submit documents to maintain a
 trademark registration, or file papers against a third party in reliance on the
 assignee’s trademark application or registration, to the exclusion of the original
 applicant or previous assignee. The assignee must establish ownership in
 compliance with § 3.73(b) .
 

 
 

 
 37 CFR 3.73 Establishing right of assignee to take action. 

 [Editor Note: Applicable to patent applications filed under 35 U.S.C.
 111(a) , 363 or 385 
 on or after September 16, 2012. See pre-AIA 37 CFR 3.73 for the rule
 otherwise applicable.] 

 
 (a) The original applicant is presumed to be the owner of an
 application for an original patent, and any patent that may issue therefrom,
 unless there is an assignment. The original applicant is presumed to be the owner
 of a trademark application or registration, unless there is an assignment.
 

 (b) In order to request or take action in a trademark
 matter, the assignee must establish its ownership of the trademark property of
 paragraph (a) of this section to the satisfaction of the Director. The
 establishment of ownership by the assignee may be combined with the paper that
 requests or takes the action. Ownership is established by submitting to the Office
 a signed statement identifying the assignee, accompanied by either:
 
 (1) Documentary evidence of a chain of title from the
 original owner to the assignee ( e.g., copy of an executed
 assignment). The documents submitted to establish ownership may be required
 to be recorded pursuant to § 3.11 in the assignment records of the Office as
 a condition to permitting the assignee to take action in a matter pending
 before the Office; or
 

 (2) A statement specifying where documentary evidence
 of a chain of title from the original owner to the assignee is recorded in
 the assignment records of the Office ( e.g., reel and
 frame number).
 

 
 

 (c)
 
 (1) In order to request or take action in a patent
 matter, an assignee who is not the original applicant must establish its
 ownership of the patent property of paragraph (a) of this section to the
 satisfaction of the Director. The establishment of ownership by the assignee
 may be combined with the paper that requests or takes the action. Ownership
 is established by submitting to the Office a signed statement identifying
 the assignee, accompanied by either:
 
 (i) Documentary evidence of a chain of title
 from the original owner to the assignee ( e.g., copy
 of an executed assignment). The submission of the documentary evidence
 must be accompanied by a statement affirming that the documentary
 evidence of the chain of title from the original owner to the assignee
 was or concurrently is being submitted for recordation pursuant to §
 3.11; or
 

 (ii) A statement specifying where documentary
 evidence of a chain of title from the original owner to the assignee
 is recorded in the assignment records of the Office
 ( e.g., reel and frame number).
 

 
 

 (2) If the submission is by an assignee of less than
 the entire right, title and interest ( e.g., more than one
 assignee exists) the Office may refuse to accept the submission as an
 establishment of ownership unless:
 
 (i) Each assignee establishes the extent (by
 percentage) of its ownership interest, so as to account for the entire
 right, title and interest in the application or patent by all parties
 including inventors; or
 

 (ii) Each assignee submits a statement
 identifying the parties including inventors who together own the
 entire right, title and interest and stating that all the identified
 parties own the entire right, title and interest.
 

 
 

 (3) If two or more purported assignees file
 conflicting statements under paragraph (c)(1) of this section, the Director
 will determine which, if any, purported assignee will be permitted to
 control prosecution of the application.
 

 
 

 (d) The submission establishing ownership under paragraph
 (b) or (c) of this section must show that the person signing the submission is a
 person authorized to act on behalf of the assignee by:
 
 (1) Including a statement that the person signing
 the submission is authorized to act on behalf of the assignee;
 

 (2) Being signed by a person having apparent
 authority to sign on behalf of the assignee; or
 

 (3) For patent matters only, being signed by a
 practitioner of record.
 

 
 

 
 

 

 The owner or assignee of a patent property can take action in
 a patent application as the applicant. However, an owner or assignee that is a juristic
 entity must be represented by a patent practitioner. See 37 CFR 1.31 and
 
 1.33(b)(3) . 
 

 An assignee who is not the original applicant must become the
 applicant under 37 CFR 1.46(a) in order to request or take action in a patent
 application. A request to change the applicant under 37 CFR
 1.46(c)(2) must be filed and must be accompanied by an application
 data sheet under 37
 CFR 1.76 specifying the applicant in the applicant information
 section and comply with 37 CFR 3.71 and 37 CFR 3.73 . 
 

 As the applicant, the owner or assignee that is not a
 juristic entity can sign a reply to an Office action ( 37 CFR
 1.33(b)(3) ), a request for a continued prosecution application under
 37 CFR
 1.53(d) ( MPEP § 201.06(d) ), a disclaimer under
 37 CFR
 1.321 ( MPEP § 1490 ), Fee(s) Transmittal (PTOL-85B)
 ( MPEP §
 1306 ), or a request for status of an application
 ( MPEP §
 102 ). The owner or assignee can file an application under
 37 CFR
 1.46 , appoint its own registered patent practitioner to prosecute an
 application ( 37 CFR
 1.32 ), and grant a power to inspect an application
 ( MPEP §
 104 ). The owner or assignee can consent to the filing of a
 reissue application ( MPEP §
 1410.01 ), and to the correction of inventorship
 ( MPEP §
 602.01(c) or MPEP § 1481 ). 
 

 Effective September 16, 2012, juristic entities may sign
 small entity assertions under 37 CFR 1.27 ( MPEP § 509.03 ),
 disclaimers under 37
 CFR 1.321 ( MPEP § 1490 ), submissions under
 37 CFR
 3.73 to establish ownership, powers of attorney under
 37 CFR
 1.32 ( MPEP § 402 ) and powers to inspect under 37 CFR 1.14 
 ( MPEP §
 104 ). However, any other paper submitted on behalf of a juristic
 entity on or after September 16, 2012, must be signed by a patent practitioner. 
 

 See subsection VI below for a discussion of when ownership
 must be established to take action in a patent matter, and subsection VII below for a
 discussion of when ownership need not be established to sign certain papers.
 

 I. THE ASSIGNEE/OWNER THAT CAN TAKE ACTION IN PATENT MATTERS The original applicant is presumed to be the owner of an
 application for an original patent, and any patent that may issue therefrom, unless
 there is an assignment. 37 CFR 3.73(a) . 
 

 The provisions of 37 CFR 3.71(b) provide that the
 assignee(s) who may conduct either the prosecution of a national application for patent
 as the applicant under 37 CFR 1.46 or a supplemental
 examination or reexamination proceeding are:
 

 
 (1) a single assignee who is the assignee of the
 entire right, title and interest in the application or patent, or
 

 (2) all partial assignees, or all partial assignees
 and inventors who have not assigned their right, title and interest in the
 application or patent, who together own the entire right, title and interest in
 the application or patent.
 

 
 As discussed in subsection II below, all parties having
 any portion of the ownership must join in “taking action” (i.e., act together as a
 composite entity) in order to be entitled to conduct the prosecution in patent matters.
 For a discussion of the applicant for patent, see MPEP § 409 et seq. and
 §
 605 et seq. 
 

 A. Individual and Partial Assignees If there is a single assignee of the entire right,
 title and interest in the patent application, 37 CFR 3.71(b)(1) provides that
 the single assignee (i.e., individual assignee) may act alone to conduct the
 prosecution of an application or other patent proceeding. If the assignee is not
 already the applicant under 37 CFR 1.46 in the patent
 application, then the assignee must file a request to change the applicant under
 37 CFR
 1.46(c)(2) . 
 

 If there is no assignee of the entire right, title and
 interest of the patent application, then either:
 

 
 (1) The application has not been assigned,
 37 CFR
 3.71 is not applicable, and the prosecution must be
 conducted by the applicant. The word "applicant" refers to the inventor or all
 of the joint inventors, or to the person applying for a patent as provided in
 37 CFR
 1.43 , 1.45 , or 1.46 .
 See MPEP §
 409 et seq. and §
 605 et seq.
 

 (2) The application has been assigned by at least
 one of the inventors, and there is thus at least one “partial assignee.” As
 defined in 37 CFR 3.71(b)(2) , a
 partial assignee is any assignee of record who has less than the entire right,
 title and interest in the application. The application is owned by the
 combination of all partial assignees and all inventors who have not assigned
 away their right, title and interest in the application.
 

 
 Where at least one inventor retains an ownership
 interest together with the partial assignee(s), the combination of all partial
 assignees and inventors retaining ownership interest is needed to conduct the
 prosecution of an application, unless one or more inventors have refused to join in
 the filing of the application and a petition under 37 CFR
 1.46(b)(2) has been granted. 
 

 Where a reissue application is filed to correct
 inventorship in the patent by the deletion of the name of inventor X and inventor X
 has not assigned their rights to the patent, inventor X has an ownership interest in
 the patent. Inventor X must consent to the filing of the reissue application, even
 though inventor X is being deleted; however, inventor X need not sign the reissue
 oath or declaration. If inventor X has assigned their rights to the patent, then
 inventor X’s assignee must consent to the filing of the reissue application. 
 

 B. Example Inventors A and B invent a process and file a patent
 application as the applicant, naming both inventors. Inventors A and B together may
 conduct prosecution of the application. 
 

 Inventor A then assigns all their rights in the
 application to Corporation X. Corporation X and Inventor B together may conduct
 prosecution of the application only if Corporation X (now a partial assignee as per
 37 CFR
 3.71(b)(2) ) is made of record in the application as a partial
 assignee and the applicant is changed under 37 CFR
 1.46(c)(2) to Corporation X and Inventor B. Pursuant to
 37 CFR
 1.46(c)(2) , an application data sheet must be filed specifying
 the applicant (i.e., Corporation X and Inventor B) in the applicant information
 section, and a statement pursuant to 37 CFR 3.73(c) must be filed
 establishing that Corporation X is an assignee of an undivided interest in the
 entirety of the application. 
 

 Corporation X and Inventor B then both assign their
 rights in the application to Corporation Y. Corporation Y is then the sole (one
 hundred percent) owner and may, by itself, conduct prosecution of the application
 after Corporation Y (now an assignee of the entire right, title and interest) is made
 of record in the application as the applicant (by filing a request to change the
 applicant under 37 CFR 1.46(c)(2) , an application
 data sheet pursuant to 37 CFR 1.76 specifying the
 applicant as Corporation Y, and a statement pursuant to 37 CFR
 3.73(c) establishing that Corporation Y is assignee of the
 entire right, title and interest). 
 

 II. ESTABLISHING OWNERSHIP An assignee who is not the original applicant must become
 the applicant under 37 CFR 1.46 in order to request or
 take action in a patent application. When an assignee who is not the original applicant
 first seeks to take action in a matter before the Office with respect to a patent
 application filed on or after September 16, 2012, the assignee must establish its
 ownership of the property to the satisfaction of the Director. 37 CFR
 3.73(c) . The assignee must also file a request to change the
 applicant under 37 CFR 1.46(c)(2) and an application
 data sheet under 37 CFR 1.76 specifying the applicant in the application
 information section. When an assignee who was not the original applicant or patent owner
 first seeks to take action in a matter before the Office with respect to a reissue
 patent application, patent, reexamination proceeding or supplemental examination
 proceeding for a patent that issued from an application filed on or after September 16,
 2012, the assignee must establish its ownership of the property to the satisfaction of
 the Director. 37
 CFR 3.73(c) . 
 

 The statement establishing assignee’s ownership under
 37 CFR
 3.73(c) must be filed in the Office file related to the matter in
 which action is sought to be taken, and must contain:
 

 
 (A) documentary evidence of a chain of title from
 the original owner to the assignee (e.g., copy of an executed assignment submitted
 for recording) and a statement affirming that the documentary evidence of the
 chain of title from the original owner to the assignee was, or concurrently is,
 submitted for recordation pursuant to 37 CFR 3.11 ; or
 

 (B) a statement specifying, by reel and frame
 number, where such evidence is recorded in the Office. 
 

 
 Documents submitted to establish ownership are required to
 be recorded, or submitted for recordation pursuant to 37 CFR 3.11 , as a
 condition to permitting the assignee to take action in a matter pending before the
 Office. 35 U.S.C.
 261 requires transfer of ownership by an assignment to be in
 writing. See Realvirt, LLC v. Lee, 195 F.Supp.3d 847, 859 (E.D. Va.
 2016). 
 

 The action taken by the assignee, and the
 37 CFR
 3.73(c) submission establishing that the assignee is the
 appropriate assignee to take such action, can be combined in one paper. 
 

 The establishment of ownership by the assignee (and the
 request for change of applicant under 37 CFR 1.46(c)(2) ) must be submitted
 prior to, or at the same time as, the paper requesting or taking action is submitted.
 37 CFR
 3.73(c) . If the submission establishing ownership and the request
 for change of applicant are not present, the action sought to be taken will not be given
 effect. If the submission establishing ownership is submitted at a later date, that date
 will be the date of the request for action or the date of the assignee’s action
 taken.
 

 The submission establishing ownership by the assignee must
 be signed by a party who is authorized to act on behalf of the assignee or a patent
 practitioner of record. See discussion below. Once 37 CFR 3.73(c) 
 is complied with by an assignee, that assignee may continue to take action in that
 application, patent, or reexamination proceeding without filing a 37 CFR 3.73(c) 
 submission each time, provided that ownership has not changed. 
 

 Where there is more than one assignee (i.e., partial
 assignees) or a combination of partial assignees and inventors who have not assigned
 away their right, title and interest in the application, each owner must submit a
 statement under 37
 CFR 3.73(c) that either:
 

 
 (A) Specifies (by percentage) the extent of its
 ownership interest, so as to account for the entire right, title and interest in
 the application or patent by all parties. 37 CFR 3.73(c)(2)(i) ; or
 

 (B) Identifies the parties including inventors who
 together own the entire right, title and interest and state that all the
 identified parties own the entire right, title and interest. 37 CFR
 3.73(c)(2)(ii) . 
 

 
 The submission establishing ownership by the assignee
 pursuant to 37 CFR
 3.73(c) is generally referred to as the “statement under 37 CFR
 3.73(c)” or the “37 CFR 3.73(c) statement.” A duplicate copy of the 37 CFR 3.73(c) 
 statement is not required and should not be submitted. See 37 CFR 1.4(b) and
 MPEP §
 502.04 . 
 

 III. CONTINUING APPLICATIONS When an assignee files a continuing application under
 37 CFR
 1.53(b) , the application papers must:
 

 
 (A) contain a copy of a statement filed under
 pre-AIA 37
 CFR 3.73(b) or under 37 CFR 3.73(c) in the parent
 application; or 
 

 (B) contain a newly executed statement under
 37 CFR
 3.73(c) . 
 

 
 When a CPA under 37 CFR 1.53(d) is filed in a design
 application, the statement filed under pre-AIA 37 CFR 3.73(b) or under
 37 CFR
 3.73(c) in the parent application will serve as the statement for
 the CPA. 
 

 IV. REQUESTS FOR CONTINUED EXAMINATION Where a Request for Continued Examination (RCE) of an
 application is filed under 37 CFR 1.114 , the application is not
 considered to be abandoned; rather the finality of the Office action is withdrawn and
 the prosecution continues. Thus, the statement under pre-AIA 37 CFR 3.73(b) or under
 37 CFR
 3.73(c) in the application will continue to serve as the statement
 establishing ownership.
 

 V. PARTY WHO MUST SIGN The submission establishing ownership must be signed by a
 party authorized to act on behalf of the assignee. The submission under
 37 CFR
 3.73(c) may be signed on behalf of the assignee in the following
 manner if the assignee is an organization (e.g., corporation, partnership, university,
 government agency, etc.):
 

 
 (A) The submission may be signed by a person in the
 organization having apparent authority to sign on behalf of the organization.
 37
 CFR 3.73(d)(2) . An officer (chief executive officer,
 president, vice-president, secretary, or treasurer) is presumed to have authority
 to sign on behalf of the organization. The signature of the chairman of the board
 of directors is acceptable, but not the signature of an individual director.
 Modifications of these basic titles are acceptable, such as vice-president for
 sales, executive vice-president, assistant treasurer, vice-chairman of the board
 of directors. In foreign countries, a person who holds the title “Manager” or
 “Director” is normally an officer and is presumed to have the authority to sign on
 behalf of the organization. A person having a title (administrator, general
 counsel) that does not clearly set forth that person as an officer of the assignee
 is not presumed to have authority to sign the submission on behalf of the
 assignee. In this situation the Office recommends that when such person is
 authorized to act on behalf of the assignee, the submission clearly indicate the
 authority (see paragraph (B), below). A power of attorney ( 37 CFR
 1.32(b)(4) ) to a patent practitioner to prosecute a patent
 application executed by the applicant or the assignee of the entire interest does
 not make that practitioner an official of an assignee or empower the practitioner
 to sign the submission on behalf of the assignee.
 

 (B) The submission may be signed by any person, if
 the submission sets forth that the person signing is authorized (or empowered) to
 act on behalf of the assignee, i.e., to sign the submission on behalf of the
 assignee. 37 CFR 3.73(d)(1) .
 

 (C) The submission may be signed by a patent
 practitioner of record. 37 CFR 3.73(d)(3) . A patent
 practitioner will be considered “of record” where the patent practitioner was
 appointed in a power of attorney already of record, or where the 37 CFR
 3.73(c) statement is accompanied by a power of attorney that
 appoints the patent practitioner who signed the statement. See
 MPEP §
 402 .
 

 (D) The submission may be signed by a person
 empowered by an organizational resolution (e.g., corporate resolution, partnership
 resolution) to sign the submission on behalf of the assignee, if a copy of the
 resolution is, or was previously, submitted in the record. 
 

 
 Where a submission does not comply with (A), (B), (C) or
 (D) above, evidence of the person’s authority to sign will be required.
 

 VI. WHEN OWNERSHIP MUST BE ESTABLISHED Examples of situations where ownership must be established
 under 37 CFR
 3.73(c) are when the assignee who is not the applicant: signs a
 request for status of an application or gives a power to inspect an application
 ( MPEP §
 102 and § 104 ); appoints its own registered
 attorney or agent to prosecute an application ( 37 CFR 3.71 and
 MPEP §
 402.07 ); signs a disclaimer under 37 CFR 1.321 
 ( MPEP §
 1490 ); consents to the filing of a reissue application
 ( MPEP §
 1410.01 ); or signs a Fee Transmittal (PTOL-85B)
 ( MPEP §
 1306 ). Effective September 16, 2012, a juristic entity (e.g.,
 organizational assignee) must be represented by a patent practitioner.
 

 VII. WHEN OWNERSHIP NEED NOT BE ESTABLISHED Examples of situations where ownership need not be
 established under 37 CFR 3.73(c) are when the assignee: signs a small entity
 statement under 37
 CFR 1.27 ( MPEP § 509.03 ); signs a statement of
 common ownership of two inventions ( MPEP § 2146.02 ); signs a NASA or DOE
 property rights statement ( MPEP § 151 ); signs an affidavit under 37 CFR
 1.131(a) where the inventor is unavailable ( MPEP § 715.04 ); signs
 a certificate under 37
 CFR 1.8 ( MPEP § 512 ); or files a request for
 reexamination of a patent under 37 CFR 1.510 ( MPEP § 2210 ).
 

 VIII. MULTIPLE ASSIGNEES When an assignee seeks to take action in a matter before
 the Office with respect to a patent application, patent, or reexamination proceeding and
 the right, title, and interest therein is held by more than one assignee, each partial
 assignee must provide a submission under 37 CFR 3.73(c) . In each submission,
 the extent of each assignee’s interest must be set forth so that the Office can
 determine whether it has obtained action by the entirety of the right, title and
 interest holders (owners). 37 CFR 3.73(c)(2)(i) . Where there
 are unspecified percentages of ownership, each partial assignee must submit a statement
 identifying the parties including inventors who together own the entire right, title and
 interest and state that all the identified parties own the entire right, title and
 interest. 37 CFR
 3.73(c)(2)(ii) . If the extent of the partial assignee’s ownership
 interest is not set forth in the submission under 37 CFR
 3.73(c) , the Office may refuse to accept the submission as an
 establishment of ownership interest. 
 

 IX. CONFLICTING 37 CFR 3.73(c) STATEMENTS Where two or more purported assignees file conflicting
 37 CFR
 3.73(c) statements in an application or other Office proceeding,
 the Director will determine which, if any, purported assignee will be permitted to
 control prosecution of the application. 37 CFR 3.73(c)(3) . Additionally, if
 the ownership established as controlling is contested on the record by another party who
 has submitted a conflicting 37 CFR 3.73(c) statement, then the
 application or other proceeding shall be forwarded by the Office official in charge of
 the application or other proceeding to the Office of Patent Legal Administration for
 resolving any procedural issues. Generally, where there are two or more conflicting
 37 CFR
 3.73(c) statements in an application, the applicant will be
 permitted to conduct the prosecution, and the other party that submitted a
 37 CFR
 3.73(c) statement to establish its ownership may wish to consider
 filing its own application.
 

 X. FORMS Form PTO/AIA/96 may be used to establish ownership under
