Please use the following addresses when mailing or hand-carrying correspondence 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 "Mail to be Directed to the Director of the Patent and Trademark Office" 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.
Most correspondence may be submitted electronically. See the USPTO's Electronic Filing System (EFS-Web) Internet web page http://www.uspto.gov/patents/process/file/efs/index.jsp for additional information.
