f your grounds for cancellation are timely, you may be able to file a Petition to cancel the blocking registration(s). For example, a cancellation based on previous use (i.e., priority) is only available for registrations that are less than 5 years old. If you file a cancellation petition against the cited registration, you may request that your trademark application be suspended pending the outcome of the cancellation proceeding.
The trademark registration will be canceled if the registration owner (registrant) fails to respond to the petition. If the registrant submits an answer, you may still be able to pursue certain outcomes that do not necessitate litigating the case to its conclusion. For example, by signing a consent agreement, the parties may be able to negotiate a friendly coexistence.
