It is not necessary to file a §7 amendment to change the address of the owner of a registration. The Change Address or Representation form in the trademark electronic filing system may be used to make such a change.
Note: The owner address will differ from the correspondence address only if a qualified U.S. attorney has been recognized. See TMEP §609.02(e) for information regarding changing the correspondence address after registration.
