Which of the following is NOT a requirement to file a change of name?

To successfully file a change of name for a trademark, providing proof of trademark use is not a requirement. The process primarily entails submitting essential paperwork and ensuring that the appropriate fee is paid. This means that even if the trademark has not been used in commerce, the name can still be officially changed by following the correct procedures.

The necessity of an assignment recordation cover sheet is critical, as it facilitates the proper documentation of the name change in the United States Patent and Trademark Office (USPTO) records. Additionally, payment of the required fee is essential for processing the name change request. Both of these elements are required to ensure that the name change is officially recognized and recorded.

In summary, while the assignment cover sheet and fee payment are compulsory components of the name change procedure, evidence of trademark use is not required specifically for changing a name, thus making it the correct answer in this context.
