Where can you find more information about maintaining a trademark registration?

The best source for information about maintaining a trademark registration is the dedicated "keeping your registration alive" webpage. This webpage specifically focuses on the requirements and procedures necessary to ensure that a trademark registration remains active and in good standing. It outlines the necessary actions, such as filing maintenance documents and deadlines, which are critical for trademark owners to understand in order to protect their rights.

While the USPTO home page offers a broad range of resources and links related to trademarks, it does not provide specific details solely focused on the maintenance of trademark registrations. The fee schedule document lists fees associated with various trademark activities but does not provide procedural information on maintaining a registration. Similarly, the trademark application guidelines are focused on the process of applying for a trademark rather than the requirements for keeping an existing registration active. Therefore, the most direct and relevant resource for this topic is indeed the "keeping your registration alive" webpage.
