37 CFR § 2.125 - Filing and service of testimony.
(a) One copy of the declaration or affidavit prepared in accordance with § 2.123, together with copies of documentary exhibits and duplicates or photographs of physical exhibits, shall be served on each adverse party at the time the declaration or affidavit is submitted to the Trademark Trial and Appeal Board during the assigned testimony period.
(b) One copy of the transcript of each testimony deposition taken in accordance with § 2.123 or § 2.124, together with copies of documentary exhibits and duplicates or photographs of physical exhibits, shall be served on each adverse party within thirty days after completion of the taking of that testimony. If the transcript with exhibits is not served on each adverse party within thirty days or within an extension of time for the purpose, any adverse party which was not served may have remedy by way of a motion to the Trademark Trial and Appeal Board to reset such adverse party's testimony and/or briefing periods, as may be appropriate. If the deposing party fails to serve a copy of the transcript with exhibits on an adverse party after having been ordered to do so by the Board, the Board, in its discretion, may strike the deposition, or enter judgment as by default against the deposing party, or take any such other action as may be deemed appropriate.
(c) The party who takes testimony is responsible for having all typographical errors in the transcript and all errors of arrangement, indexing and form of the transcript corrected, on notice to each adverse party, prior to the filing of one certified transcript with the Trademark Trial and Appeal Board. The party who takes testimony is responsible for serving on each adverse party one copy of the corrected transcript or, if reasonably feasible, corrected pages to be inserted into the transcript previously served.
(d) One certified transcript and exhibits shall be filed with the Trademark Trial and Appeal Board. Notice of such filing shall be served on each adverse party and a copy of each notice shall be filed with the Board.
(e) Each transcript shall comply with § 2.123(g) with respect to arrangement, indexing and form.
(f) Upon motion by any party, for good cause, the Trademark Trial and Appeal Board may order that any part of an affidavit or declaration or a deposition transcript or any exhibits that directly disclose any trade secret or other confidential research, development, or commercial information may be filed under seal and kept confidential under the provisions of § 2.27(e). If any party or any attorney or agent of a party fails to comply with an order made under this paragraph, the Board may impose any of the sanctions authorized by § 2.120(h).
