The Trademark Trial and Appeal Board (“TTAB”) of the United States Patent and Trademark Office (“USPTO”) is the administrative forum that adjudicates all trademark opposition and cancellation proceedings that are filed in the United States Patent and Trademark Office.   A case is commenced by the filing of a Notice of Opposition (in the case of an Opposition) or a Petition for Cancellation (in the case of a Cancellation).  The TTAB assigns an interlocutory attorney to each opposition or cancellation proceeding.  The interlocutory attorney is responsible for setting the discovery and trial schedule and all deadlines and actions that relate to the case, as well as hearing motions brought by either party.
