What is true about fees for filing a change of address for a trademark?

When filing a change of address for a trademark, it is correct that there are no fees associated with this action. The United States Patent and Trademark Office (USPTO) allows trademark owners to update their address information without incurring any charges. This is important because it ensures that trademark owners can keep their registration information current and receive any official correspondence from the USPTO without financial barriers.

Filing a change of address is a straightforward process that does not involve any filing fees, making it accessible for all trademark owners who need to update their information due to relocation or other reasons. This policy reflects the USPTO's commitment to maintaining accurate and up-to-date records for trademark registrations, which is essential for the protection of trademark rights.

Other options suggest scenarios where fees would apply or conditions under which a fee might be charged, but none of those apply for a simple change of address.
