	     MAIL TO THE UNITED STATES PATENT AND TRADEMARK OFFICE

	      MAIL TO BE DIRECTED TO THE COMMISSIONER FOR PATENTS

   For most correspondence (e.g., new patent applications) no mail stop 
is required because the processing of the correspondence is routine.  
If NO mail stop is included on the list below, no mail stop is required 
for the correspondence. See the listing under "Special Mail Stops 
Applicable To Both Patent And Trademark Mail" for additional mail stops 
for patent-related correspondence.  Only the specified type of document 
should be placed in an envelope addressed to one of these special mail 
stops. If any documents other than the specified type identified for each 
special mail stop are addressed to that mail stop, they will be 
significantly delayed in reaching the appropriate area for which they are 
intended. The mail stop should generally appear as the first line in
the address.

   Some correspondence may be submitted electronically. See the Office's 
Internet Web site http://www.uspto.gov for additional information.
