512.01 Assignment of Mark
When there has been an assignment of a mark that is the subject of, or relied upon in, an inter partes proceeding before the Board, the assignee may be joined or substituted, as may be appropriate, upon motion granted by the Board, or upon the Board’s own initiative. [ Note 1.]
When a mark that is the subject of a Federal application or registration has been assigned, together with the application or registration, in accordance with Trademark Act § 10, 15 U.S.C. § 1060, any action with respect to the application or registration that may or must be taken by the applicant or registrant may be taken by the assignee (acting itself, or through its attorney or other authorized representative), provided that the assignment has been recorded with the USPTO or that proof of the assignment has been submitted in the Board proceeding record. [ Note 2.]
Please Note: Trademark Act § 10, 15 U.S.C. § 1060, and part 3 of 37 C.F.R. are not applicable to Trademark Act § 66(a), 15 U.S.C. § 1141f(a), applications and registrations. [ Note 3.] Except in limited circumstances, [ Note 4.] requests to record assignments of § 66(a) applications and registrations must be filed directly with the International Bureau. [ Note 5.] The International Bureau will notify the USPTO of any changes in ownership recorded in the International Register. The USPTO will record only those assignments, or other documents of title, that have been recorded with the International Bureau. [ Note 6.]
If the mark in an application or registration that is the subject matter of an inter partes proceeding before the Board is assigned, together with the application or registration, the assignee may be joined as a party (as a party defendant, in the case of an opposition or cancellation proceeding; or as a junior or senior party, as the case may be, in an interference or concurrent use proceeding) upon the filing with the Board of a copy of the assignment. When the assignment is recorded in the Assignment Recordation Branch of the USPTO [ Note 7.], the assignee may be substituted as a party if the assignment occurred prior to the commencement of the proceeding [ Note 8.], the assignor is no longer in existence, the plaintiff raises no objections to substitution, or the discovery and testimony periods have closed; otherwise, the assignee will be joined, rather than substituted, to facilitate discovery. [ Note 9.]
If a mark pleaded by a plaintiff is assigned and a copy of the assignment is filed with the Board, the assignee ordinarily will be substituted for the originally named party if the assignment occurred prior to the commencement of the proceeding, if the discovery and testimony periods have closed, if the assignor is no longer in existence, or if the defendant raises no objection to substitution; otherwise, the assignee will be joined, rather than substituted, to facilitate the taking of discovery and the introduction of evidence. [ Note 10.] See TBMP § 303.05(b) (Opposition Filed by Privy). The assignment does not have to be recorded with respect to a plaintiff’s pleaded application or registration before substitution or joinder (whichever is appropriate) is made. However, recordation in the Assignment Recordation Branch of the USPTO is advisable because it will aid the assignee in its effort to prove ownership of the application or registration at trial. [ Note 11.]
If the mark of an excepted common law user (that is not the owner of an involved application or registration) in a concurrent use proceeding is assigned, the assignee will be joined or substituted as party defendant upon notification to the Board of the assignment. [ Note 12.]
Alternatively, if there has been an assignment of a mark that is the subject of, or is relied upon in, a proceeding before the Board, and the Board does not order that the assignee be joined or substituted in the proceeding, the proceeding may be continued in the name of the assignor. [ Note 13.]
Further, the fact that a third party related to the plaintiff, such as a parent or licensor of the plaintiff, may also have an interest in a mark relied on by the plaintiff does not mean that the third party must be joined as a party plaintiff. [ Note 14.]
A joint applicant may assign an intent-to-use application for registration of a mark to a second joint applicant without violating Trademark Act § 10(a)(1), 15 U.S.C. § 1060(a)(1). [ Note 15.]

512.02 Change of Name
If the name of a party to an inter partes proceeding before the Board is changed, the title of the Board proceeding may be changed, upon motion or upon the Board’s own initiative, to reflect the change of name, provided that appropriate evidence thereof is made of record in the proceeding. Such evidence may consist, for example, of a copy of the name change document, or the reel and frame numbers at which such document is recorded in the Assignment Recordation Branch of the USPTO. [ Note 1.] If no such evidence is made of record in the proceeding, the proceeding may be continued in the party’s old name. [ Note 2.] See note to TBMP § 512.01 regarding assignments of Trademark Act § 66(a), 15 U.S.C. § 1141f(a) applications and registrations.
A name change document does not have to be recorded in the Assignment Recordation Branch of the USPTO with respect to a defendant’s involved application or registration, or a plaintiff’s pleaded application or registration, in order for the Board proceeding title to be changed to reflect the new name. However, recordation is advisable because it facilitates proof of ownership of the application or registration, and because filing for recordation is one of the 37 C.F.R. § 3.85 requirements for an applicant that desires, if it prevails in the proceeding, to have its registration issue in its new name. [ Note 3.] See TBMP § 512.03 (Issuance of Registration to Assignee, or in New Name).

512.03 Issuance of Registration to Assignee, or in New Name
37 C.F.R. § 3.85 Issue of registration to assignee. The certificate of registration may be issued to the assignee of the applicant, or in a new name of the applicant, provided that the party files a written request in the trademark application by the time the application is being prepared for issuance of the certificate of registration, and the appropriate document is recorded in the Office. If the assignment or name change document has not been recorded in the Office, then the written request must state that the document has been filed for recordation. The address of the assignee must be made of record in the application file.
Even where the assignee of an application that is the subject matter of a Board inter partes proceeding has been joined or substituted as a party to the proceeding, see TBMP § 512.01, any registration issued from the application may issue in the name of the assignor unless the assignee complies with the requirements of 37 C.F.R. § 3.85. Specifically, to ensure that the registration will issue in its name, the assignee must file a written request in the application (or in the Board proceeding, if that proceeding has not yet ended), by the time the application is being prepared for issuance of the certificate of registration that the registration be issued in its name. [ Note 1.] In addition, an appropriate document must be of record in the Assignment Recordation Branch of the USPTO, or the written request must state that the document has been filed for recordation. Finally, the address of the assignee must be made of record in the application file.
Similarly, even though the title of an inter partes proceeding before the Board may have been changed to reflect a name change of an applicant whose application is the subject of the proceeding, any registration issued from the application may issue in the applicant’s original name unless the applicant complies with the requirements of 37 C.F.R. § 3.85. [ Note 2.] If an assignment or change of name document is recorded in the Assignment Recordation Branch well prior to the time the subject application is prepared for issuance of a registration, the registration may issue in the name of the assignee, or in the new name, even if no 37 C.F.R. § 3.85 request is filed. However, the registration may issue in the name of the assignor or in the old name. The purpose of the written request is to call the attention of the USPTO to the assignment or change of name and thus to ensure that the registration issues in the name of the assignee or in the new name. Accordingly, it is sufficient for the purpose if applicant files a paper referring to the assignment or change of name and the assignment or change of name document has either been recorded, or applicant states that the document has been submitted for recording. [ Note 3.]
Please Note: Trademark Act § 10, 15 U.S.C. § 1060, and part 3 of 37 C.F.R. are not applicable to Trademark Act § 66(a), 15 U.S.C. § 1141f(a), applications and registrations. [ Note 4.] Except in limited circumstances [ Note 5.], requests to record assignments of § 66(a) applications and registrations must be filed directly with the International Bureau. [ Note 6.] The International Bureau will notify the USPTO of any changes in ownership recorded in the International Register. The USPTO will record only those assignments, or other documents of title, that have been recorded in the International Register. [ Note 7.]

512.04 Misidentification
Fed. R. Civ. P. 15(a) Amendments Before Trial.
- (1) Amending as Matter of Course. A party may amend its pleading once as a matter of course within: (A) 21 days after serving it, or (B) if the pleading is one to which a responsive pleading is required, 21 days after service of a responsive pleading or 21 days after service of a motion under Rule. 12(b), (e), or (f), whichever is earlier.
- (2) Other Amendments. In all other cases, a party may amend its pleading only with the opposing party’s written consent or the court’s leave. The court should freely give leave when justice so requires.
15 U.S.C. § 1063(a) … An opposition may be amended under such conditions as may be prescribed by the Director.
When the plaintiff in a Board inter partes proceeding misidentifies itself or the mark or registration upon which it relies in the complaint, if the plaintiff can establish to the Board’s satisfaction that this misidentification was merely a non-substantive mistake, the Board may allow amendment of the complaint, pursuant to Fed. R. Civ. P. 15(a), to correct the misidentification and/or to substitute the proper party in interest. [ Note 1.] See TBMP § 303.05(c) (Misidentification of Opposer).
When the plaintiff in a Board inter partes proceeding misidentifies an application or registration number that is the subject of the Board proceeding, and the plaintiff can establish, in a timely manner and to the Board’s satisfaction that this misidentification was a non-substantive mistake, the Board may allow amendment of the complaint (and of the Board proceeding title) to correct the misidentification of the subject application or registration. [ Note 2.] However, if a notice of opposition misidentifies the application number(s) against which the opposition is intended, and the defect is not corrected within the time for filing an opposition against the intended application(s) under Trademark Act § 13(a), 15 U.S.C. § 1063(a), this defect cannot be cured. The opposition against the misidentified application will be dismissed and an opposition against the intended application will not be instituted because it would be untimely. [ Note 3.] See also TBMP § 306.04. Similarly, if a petition to cancel misidentifies the registration number against which the cancellation is intended, and the defect is not corrected within the time for petitioning to cancel the intended registration under Trademark Act § 14, 15 U.S.C. § 1064, this defect cannot be cured. The petition to cancel the misidentified registration will be denied and a petition to cancel the intended registration will not be instituted because it would be untimely.
An applicant may correct a defect in identifying itself by name or legal entity in the application where it is a single, continuing commercial entity and was the owner of the mark as of the filing date of the application and that entity in fact filed the application. [ Note 4.] Also, where a merger occurred prior to filing an application, but the pre-merger corporation and owner of the mark has ceased to exist and is identified as the applicant, the corporation that remains after the merger may correct this defect by identifying itself as applicant. [ Note 5.]
