United States Patent and Trademark Office OG Notices: 01 June 2004

                        New Address for Customer Window
                         Which is Used for Patent Mail
                           Not Delivered by the USPS

   Effective June 5, 2004, street addresses for several of the buildings
of the United States Patent and Trademark Office (USPTO), including the
Crystal Plaza Two building which is the location of the Customer Window,
have been changed.  The Customer Window is the delivery location for
patent-related correspondence to be hand or courier delivered to the USPTO
by delivery services such as FedEx, UPS, DHL, Laser, Action, Purolator,
etc. The customer window is not used for correspondence delivered by the
United States Postal Service (USPS). This change is made because the street
on which the Crystal Plaza Two building is located will be redesignated
from South Clark Place to 20th Street S.

   Patent-related correspondence sent through the USPS should continue to
be directed to the addresses set forth in 37 CFR 1.1 (revised effective
January 21, 2004) (e.g., P.O. Box 1450, Alexandria, VA 22313-1450). The
change in the street address for the Crystal Plaza Two building which
houses the Customer Window does not affect the Mail Stop designations,
which should always be used for certain patent mail.

   Although the physical location of the Customer Window (the building and
room number) will remain the same, on June 5, 2004 the street address of
the Crystal Plaza Two building will change from 2011 South Clark Place to
220 20th Street S.  Accordingly, effective June 5, 2004, patent mail
delivered by hand or delivery services to the Customer Window (and not the
USPS) must be addressed as follows:

        U.S. Patent and Trademark Office
        220 20th Street S.
        Customer Window, Mail Stop ________
        Crystal Plaza Two, Lobby, Room 1B03
        Arlington, VA  22202

   During business hours, correspondence for international patent
applications may be brought directly to the PCT Operations Receptionist on
the 8th floor of the Crystal Plaza 2 building.

   Also effective June 5, 2004, will be changes in the street addresses
of three other USPTO buildings in the Crystal City complex.  The street
address changes are as follows: the Crystal Plaza Three building will be
2100 Crystal Drive; the Crystal Plaza Four building will be 2200 Crystal
Drive; and the Crystal Square Two building will be 1550 Crystal Drive.
These changes should be noted in case interviews with examiners in those
buildings will be held after June 5, 2004.

   Please be aware that the new address for the Customer Window is only
temporary. In August or September of 2004, the Customer Window will be
moving to the Alexandria campus.  At that time, the address for patent mail
delivered by hand or delivery services to the Customer Window (and not the
USPS) will be changed yet again to a new Customer Window located on the
Alexandria campus.  A separate notice will be published in advance of the
Customer Window relocation announcing specific details. The Customer Window
location change planned for August or September will also have no affect on
the USPTO address for mail delivered by the USPS.

   The File Information Unit (also known as the Record Room) is scheduled
to move to South Tower in July of 2004.

   PCT Operations will be moving to South Tower in November or December of
2004. A separate notice will be published in advance of the PCT Operations
relocation announcing specific details.
