Where cancellation happens
Most cancellation actions are filed as petitions before the Trademark Trial and Appeal Board, and a court handling an infringement case can also order a registration canceled. Since the Trademark Modernization Act, the USPTO also offers streamlined expungement and reexamination proceedings aimed at registrations for marks that were never used, or not used when they should have been. If an examiner has refused your application because of a cited registration, challenging that registration is a separate proceeding, and your application may be suspended while it runs. The Board decides registration rights only; it does not award damages or order anyone to stop using a mark.
Grounds and the clock
Two common grounds are abandonment through non-use and likelihood of confusion with rights you held earlier; others exist, and some are hard to prove. Once a registration has been on the register for a set period, some grounds are no longer available, which makes timing important. The petitioner also has to show a real interest in the outcome, usually through its own use of a mark or a pending application. Evidence of non-use is often gathered through investigation of the registrant's presence in the market, and the findings should be documented carefully.
How a proceeding runs
A cancellation runs much like a small lawsuit, with pleadings, discovery, and a trial conducted largely on a written record. Many end in settlement, often with the registrant narrowing its goods, assigning the mark, or consenting to your registration. Before filing, it is worth asking whether the registrant might counter with claims of its own. A strong non-use challenge can also open a negotiation, since some registrants would rather reach an agreement than defend a contested proceeding. When a registration stands in your way, we look at the registration's history, the evidence of use, your own rights, and which proceeding fits the situation.
