What must be submitted if a registration is to be canceled?

When seeking to cancel a trademark registration, the correct procedure involves submitting a request through the Trademark Electronic Application System (TEAS). This system is specifically designed for various trademark-related filings, including cancellation requests. The process enables individuals or entities to challenge an existing trademark registration and initiate the cancellation proceedings.

Submitting through TEAS ensures that the request adheres to the trademark regulations set forth by the USPTO and allows for efficient processing. The system streamlines the submission of the required documents and information, ensuring that the request is properly formatted and filed.

The other options listed do not align with the correct procedure for cancellation. A renewal application is relevant to maintaining an existing registration but does not pertain to cancellation. A legal notice might be part of broader legal actions but is not the formal mechanism used for cancellation within the USPTO framework. A request for reconsideration typically applies to responses to USPTO refusals, not to the initiation of cancellation proceedings. Thus, using the Trademark Electronic Application System is the appropriate action to take when aiming to cancel a trademark registration.
