(A) Subject to paragraph (2), each application for a patent
shall be published, in accordance with procedures determined by the
Director, promptly after the expiration of a period of 18 months from
the earliest filing date for which a benefit is sought under this
title. At the request of the applicant, an application may be
published earlier than the end of such 18-month period.
(B) No information concerning published patent applications
shall be made available to the public except as the Director
determines.
(C) Notwithstanding any other provision of law, a
determination by the Director to release or not to release information
concerning a published patent application shall be final and
nonreviewable.
(2) EXCEPTIONS.—
(A) An application shall not be published if that
application is—
(i) no longer pending;
(ii) subject to a secrecy order under
section 181
;
(iii) a provisional application filed under
section
111(b)
; or
(iv) an application for a design patent filed under

after filing, the application shall not be published as provided
in paragraph (1).
(ii) An applicant may rescind a request made under

the date of the filing of such foreign or international
application. A failure of the applicant to provide such notice
within the prescribed period shall result in the application
being regarded as abandoned.

requirements of law. No part of any application or paper related thereto should be
reproduced or copied except for official purposes. Application files must not be displayed
or handled so as to permit perusal or inspection by any unauthorized member of the
public.
Whenever a paper application (non-electronic), or an artifact file in an
Image File Wrapper (IFW) application, is removed from the operating area having custody of
the file, a charge on the Patent Data Portal system must be properly and promptly made.
Applications, artifact files, and official papers for which there is no electronic file
must not be placed in desk drawers or other locations where they might be easily overlooked
or are not visible to authorized personnel. Interoffice mail must be sent in appropriate
envelopes.
Official papers are accepted only at the Customer Service Window, except for
certain papers that have been specifically exempted from the central delivery policy. See
MPEP §
502

identifications or incorrect routing should be taken at once to ensure the prompt receipt
thereof at the appropriate destination.

When handling an incoming telephone call or an in-person request for
information regarding an unpublished pending or abandoned patent application, no
information should be disclosed until the identity of the requester can be adequately
verified as set forth below. Particular care must be exercised when a request is made
for the publication date or publication number, or issue date and patent number assigned
to a
pending
patent application. If the publication or issue date is
later than the current date (i.e., the date of the request), such information may be
given

The following procedure should be followed before any information about an
unpublished pending or abandoned patent application is given over the telephone:
(A) Obtain the caller’s full name, the application number, and the
caller’s telephone number. Ask the caller if there is a patent practitioner
(attorney or agent) of record.
(1) If there is a patent practitioner of record, ask for the
patent practitioner's registration number. If the registration number is not
known, ask for the name of the patent practitioner of record. Inform the
caller that a patent practitioner of record will be called after
verification of their identity and that information concerning the
application will be released to that patent practitioner.
(2) If there is no patent practitioner of record, ask the caller
why they are entitled to information concerning the application. If the
caller identifies theirself as an inventor, an applicant or an authorized
representative of the assignee of record, ask for the correspondence address
of record and inform caller that their association with the application must
be verified before any information concerning the application can be
released and that they will be called back. If the caller indicates that
they are not an inventor, applicant or an authorized representative of the
assignee of record then status information may only be given pursuant to
MPEP §
102
.
(B) Verify that information concerning the application can be released
by checking Patent Data Portal or the application file.

(B) Verify that information concerning the application can be released
by checking Patent Data Portal or the application file.
(1) If the caller stated there was a patent practitioner of
record, Patent Data Portal should be used to verify the registration number
given or to obtain the registration number of a patent practitioner of
record. Then Patent Data Portal (using the registration number) should be
used to obtain a telephone number for a patent practitioner of record.
(2) If the caller identified theirself as an inventor, applicant
or an authorized representative of the assignee of record, Patent Data
Portal should be used to verify the correspondence address of record. Patent
Data Portal should be used to determine if there is a patent practitioner of
record. If there is a patent practitioner of record, their telephone number
can be obtained from Patent Data Portal.
(C) Return the call using the telephone number as specified below.
(1) If a patent practitioner is of record in the application,
information concerning the application should only be released by calling
the patent practitioner's telephone number obtained from Patent Data
