SPECIAL MAIL STOPS FOR PATENT MAIL

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.

Petitions for a foreign filing license may be faxed to: 703-305-7658.

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

Please address mail to be delivered by the United States Postal Service (USPS) as follows:
