An opposition is a proceeding initiated by a third party to block the applicant from receiving registration of their mark. A party that believes they will be damaged by the registration may file a notice of opposition with the Trademark Trial & Appeal Board. The opposition proceeding is very similar to a federal lawsuit and the rules of the proceeding are governed by the Trademark Trial & Appeal Board manual of procedure. The TTAB may cancel or allow the trademark but cannot award monetary damages to either party. The notice of opposition must be filed within 30 days from the notice of publication but extensions may be provided upon written notice.
