704.10    Interrogatory Answers; Admissions

37 C.F.R. § 2.120(k)  Use of discovery deposition, answer to interrogatory, admission or written disclosure.

  • * * * *
  • (3)
    • (i) A discovery deposition, an answer to an interrogatory, or an admission to a request for admission, or a written initial disclosure, which may be offered in evidence under the provisions of paragraph (j) of this section, may be made of record in the case by filing the deposition or any part thereof with any exhibit to the part that is filed, or a copy of the interrogatory and answer thereto with any exhibit made part of the answer, or a copy of the request for admission and any exhibit thereto and the admission (or a statement that the party from which an admission was requested failed to respond thereto), or a copy of the written initial disclosure, together with a notice of reliance in accordance with § 2.122(g). The notice of reliance and the material submitted thereunder should be filed during the testimony period of the party which files the notice of reliance. An objection made at a discovery deposition by a party answering a question subject to the objection will be considered at final hearing.
  • * * * *
  • (5) Written disclosures, an answer to an interrogatory, or an admission to a request for admission, may be submitted and made part of the record only by the receiving or inquiring party except that, if fewer than all of the written disclosures, answers to interrogatories, or fewer than all of the admissions, are offered in evidence by the receiving or inquiring party, the disclosing or responding party may introduce under a notice of reliance any other written disclosures, answers to interrogatories, or any other admissions, which should in fairness be considered so as to make not misleading what was offered by the receiving or inquiring party. The notice of reliance filed by the disclosing or responding party must be supported by a written statement explaining why the responding party needs to rely upon each of the additional written disclosures or discovery responses listed in the disclosing or responding party’s notice, and absent such statement, the Board, in its discretion, may refuse to consider the additional written disclosures or responses.
  • (6) Paragraph (k) of this section will not be interpreted to preclude reading or use of written disclosures or documents, a discovery deposition, or answer to an interrogatory, or admission as part of the examination or cross-examination of any witness during the testimony period of any party.
  • (7) When a written disclosure, a discovery deposition, or a part thereof, or an answer to an interrogatory, or an admission, or an authenticated produced document has been made of record by one party in accordance with the provisions of paragraph (k)(3) of this section, it may be referred to by any party for any purpose permitted by the Federal Rules of Evidence.
  • (8) Written disclosures or disclosed documents, requests for discovery, responses thereto, and materials or depositions obtained through the disclosure or discovery process should not be filed with the Board, except when submitted with a motion relating to disclosure or discovery, or in support of or in response to a motion for summary judgment, or under a notice of reliance, when permitted, during a party’s testimony period.

Ordinarily, an answer to an interrogatory, or an admission to a request for admission, may be submitted and made part of the record by only the inquiring party. [ Note 1.] See TBMP § 401 and TBMP § 704.14 for further information concerning disclosures.

However, if fewer than all of the answers to a set of interrogatories, or fewer than all of the admissions, are offered in evidence by the inquiring party, the responding party may introduce, under a notice of reliance, any other answers to interrogatories, or any other admissions that should be considered so as to avoid an unfair interpretation of the responses offered by the inquiring party. [ Note 2.] The notice of reliance must be supported by a written statement explaining why the responding party needs to rely on each of the additional interrogatory answers, or admissions, listed in the responding party’s notice, failing which the Board, in its discretion, may refuse to consider the additional responses. [ Note 3.]

An interrogatory answer (including documents provided as all or part of an interrogatory answer under Fed. R. Civ. P. 33), or an admission to a request for admission, [ Note 4.], that may be offered in evidence under 37 C.F.R. § 2.120(k)  may be made of record by notice of reliance during the testimony period of the offering party. The party should file a copy of the interrogatory and the answer thereto, with any exhibit made part of the answer, or a copy of the request for admission and any exhibit thereto and the admission (or a statement that the party from which an admission was requested failed to respond thereto), together with its notice of reliance thereon. [ Note 5.]

The notice of reliance must indicate the general relevance of the interrogatory answer or admission (or any part thereof) and associate it with one or more issues in the case. [ Note 6.] Interrogatory answers, or admissions, may be admitted into evidence through the testimony of a witness as an alternative to the notice of reliance procedure. [ Note 7.]

An interrogatory answer may also be made of record by stipulation of the parties, accompanied by a copy of the interrogatory and the answer thereto with any exhibit made part of the answer. Similarly, an admission may be made of record by stipulation of the parties, accompanied by a copy of the request for admission and any exhibit thereto and the admission (or a statement that the party from which an admission was requested failed to respond thereto). [ Note 8.]

When an interrogatory answer, or an admission, has been made of record by one party in accordance with 37 C.F.R. § 2.120(k), it may be referred to by any party for any purpose permitted by the Federal Rules of Evidence. [ Note 9.]

An interrogatory answer, or an admission, not properly offered in evidence under 37 C.F.R. § 2.120(k)  may nevertheless be considered by the Board if the nonoffering party (parties) does not object thereto; and/or treats the answer, or admission, as being of record; and/or improperly offers an interrogatory answer, or an admission, in the same manner. [ Note 10.]

Written disclosures, disclosed documents, requests for discovery, responses thereto, and materials or depositions obtained through the disclosure or discovery process should not be filed with the Board except when submitted (1) with a motion relating to disclosure or discovery; or (2) in support of or response to a motion for summary judgment; or (3) under a notice of reliance during a party’s testimony period; or (4) as exhibits to a testimony deposition; or (5) in support of an objection to proffered evidence on the ground that the evidence should have been, but was not, provided in response to a request for discovery. [ Note 11.] Please Note: Unlike documents that are provided as all or part of an interrogatory answer under Fed. R. Civ. P. 33, documents that are produced in response to a document request cannot be made of record under a notice of reliance unless they are otherwise eligible for submission under a notice of reliance, e.g., because they are printed publications or were provided in connection with a response to an interrogatory or unless they have been authenticated by an admission or stipulation from the producing party. [ Note 12.] See TBMP § 704.08 and TBMP § 704.11.

Nothing in 37 C.F.R. § 2.120(k)  precludes reading or using an interrogatory answer, or an admission, as part of the examination or cross-examination of any witness during the testimony period of any party. [ Note 13.]

Denials to admission requests cannot be submitted under notice of reliance. [ Note 14.] "[U]nlike an admission (or a failure to respond which constitutes an admission), the denial of a request for admission establishes neither the truth nor the falsity of the assertion, but rather leaves the matter for proof at trial. Cf. Fed. R. Civ. P. 36(b)." [ Note 15.]

Although parties are obliged to supplement their discovery responses under Fed. R. Civ. P. 26(e)(1), supplemental discovery materials served upon an adversary during trial cannot be made of record unless such materials fall under an exception in 37 C.F.R. § 2.120(k)(8). [ Note 16.]

For information concerning the taking of discovery by way of interrogatories, see TBMP § 405. For information concerning the taking of discovery by way of requests for admission and for the effect of not responding to a request for admission, see TBMP § 407. For information concerning the raising of objections to notices of reliance and materials filed thereunder, see TBMP § 532 and TBMP § 707.02.

Please Note: Some of the cases cited in this section established principles later codified in the cited provisions in former 37 C.F.R. § 2.120(j), now 37 C.F.R. § 2.120(k), or were decided under rules which were the predecessors to such provisions.
