Notice Regarding Technical Center
                            Box Issue Fee Mailings

   The Office will begin mailing address labels with the PTOL-85, "Notice
of Allowance and Issue Fee Due" for patent applications allowed in all
Technology Centers. These address labels should be used to ensure proper
routing of post-allowance correspondence. This directive supersedes the
"Special Boxes for Patent Mail" instruction. Any Notice of Allowance and
Issue Fee Due received without the accompanying address labels should
continue to be addressed to Box Issue Fee.
