In the course of examining a trademark application, the Examining Attorney may identify issues that preclude registration of your mark. They may be substantive (i.e., there is a fundamental flaw with the trademark you wish to register) or procedural (i.e., there was a problem with your application). Any issues the Examining Attorney identifies will be described in an "Office Action," to which you must respond within six (6) months of receipt.
Some problems raised by an Office Action can be corrected with an amendment to the application. Status Code 664 indicates that the USPTO has amended your application per your request or the request of your attorney. No further action is needed on your part at this time.
