Which of the following is NOT required for filing an assignment?

When filing an assignment of a trademark, the primary requirement is to provide sufficient documentation that clearly indicates the transfer of ownership. The other components listed—such as an assignment recordation cover sheet, legal documentation of ownership transfer, and the payment of any required filing fees—are necessary aspects of the process. These elements ensure that the assignment is properly documented and recognized by the USPTO.

In contrast, a trademark registration certificate is not a requirement for filing an assignment. The assignment can be made even if the trademark is not yet registered, as long as the trademark is used in commerce or has an application pending. Therefore, having a registration certificate is not a prerequisite for the assignment process to be valid. This distinction emphasizes that the transfer of rights can occur at different stages, not solely tied to the formal registration of the trademark.
