What is the ultimate deadline for a reinstatement request if no notice was received?

The ultimate deadline for a reinstatement request due to non-receipt of a notice is six months from the date of cancellation. This timeframe allows parties sufficient time to realize that their mark has been canceled and to take appropriate action for reinstatement.

The rationale behind this six-month period is to ensure that trademark owners have a reasonable opportunity to address administrative oversights or failures in communication regarding the status of their trademark. Recognizing the importance of trademarks in commerce, the USPTO provides this time frame as a safeguard to protect the rights of trademark owners who may not have received crucial notifications.

While there are various scenarios in trademark management that might establish different deadlines based on specific actions or notices, the six-month period strictly applies when no cancellation notice has been received, ensuring fairness and encouraging diligence from trademark owners.
