Discovery Practice in TTAB Trademark Proceedings: A Comprehensive Guide to Interrogatories, Requests for Production, and Requests for Admissions
This comprehensive guide explains how discovery works in inter partes proceedings before the Trademark Trial and Appeal Board (TTAB), the administrative tribunal that decides oppositions and cancellations within the U.S. Patent and Trademark Office. It walks through the framework set by the Federal Rules of Civil Procedure as modified by 37 C.F.R. § 2.120 and the Trademark Trial and Appeal Board Manual of Procedure (TBMP), including the mandatory discovery conference, initial disclosures, the 180-day discovery period, and the trial-phase structure that follows. The article details each principal discovery device -- interrogatories (capped at 75 including subparts), requests for production (also capped at 75), requests for admission, and the ten-deposition limit -- along with the post-2017 numerical limits, electronic discovery practice, and the Board's distinctive rules on expert disclosure and service timing. It covers motions to compel, the meet-and-confer obligation, discovery sanctions and estoppel, the standard protective order, and how to use discovery to build a persuasive likelihood-of-confusion record under the DuPont factors. Throughout, the guide offers worked examples, model requests, governing case law, and practical strategy for practitioners and self-represented parties alike.
