LOL, Kaitlin, I read the TTAB procedural manual from cover to cover and I know it inside and out. I also consulted with 2 IP attorneys and all of them had never ran into this situations. One did reference:
Part of TBMP 404 which outlines details for the attendance of a deponent - and specifies the United States district court in the federal judicial district where the deponent resides or is regularly employed must issue the subpoena.
404.03(a)(2) Person Residing in the United States - Nonparty
37 CFR § 2.120(b) Discovery deposition within the United States.
... The responsibility rests wholly with the party taking discovery to secure the attendance of a
proposed deponent other than a party or anyone who, at the time set for the taking of the
deposition, is an officer, director, or managing agent of a party, or a person designated under
Rule 30(b)(6) or Rule 31(a) of the Federal Rules of Civil Procedure.
If a proposed deponent residing in the United States is not a party, or a person who, at the time
set for the taking of the deposition, is an officer, director, or managing agent of a party, or a
person designated under Fed. R. Civ. P. 30(b)(6) or 31(a)(3) to testify on behalf of a party, the
responsibility rests wholly with the deposing party to secure the attendance of the proposed
deponent. [Note 1.] If the proposed deponent is not willing to appear voluntarily, the deposing
party must secure the deponent's attendance by subpoena, pursuant to 35 U.S.C. § 24 and Fed. R.
Civ. P. 45. [Note 2.]
The subpoena must be issued from the United States district court in the federal judicial district
where the deponent resides or is regularly employed. [Note 3.]
If a person named in a subpoena compelling attendance at a discovery deposition fails to attend
the deposition, or refuses to answer a question propounded at the deposition, the deposing party
must seek enforcement from the United States District Court that issued the subpoena; the Board
has no jurisdiction to enforce the subpoena. [Note 4.]
