How can you ensure your trademark registration remains active?

To keep a trademark registration active, it's essential to comply with maintenance requirements set forth by the United States Patent and Trademark Office (USPTO). This includes filing specific maintenance documents at designated intervals, such as the Declaration of Use (Section 8) and, if the trademark has been registered for more than five years, the Renewal Application (Section 9). These filings demonstrate continued use of the trademark in commerce and ensure that the registration does not become abandoned or canceled.

While filing new trademark applications (the first option) might seem beneficial, it does not maintain an existing registration. Updating the registration’s logo (the third option) could be part of a new application if the change is significant enough, but it doesn’t directly impact the maintenance of an existing registration. Advertising the trademark broadly (the fourth option) is useful for brand awareness but does not influence the trademark's active status in the eyes of the USPTO.

Thus, keeping up with the required maintenance documents is the most critical action for ensuring that a trademark registration remains active.
