[Docket No. 950706172-5172-01]
Utility Examination Guidelines
AGENCY: Patent and Trademark Office, Commerce.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Patent and Trademark Office (PTO) is publishing the final
version of guidelines to be used by Office personnel in their review of
patent applications for compliance with the utility requirement.
Because these guidelines govern internal practices, they are exempt
from notice and comment and delayed effective date rulemaking
requirements under 5 U.S.C. 553(b)(A).
EFFECTIVE DATE: July 14, 1995.
FOR FURTHER INFORMATION CONTACT: Jeff Kushan by telephone at (703) 305-
9300, by fax at (703) 305-8885, by electronic mail at kushan@uspto.gov,
or by mail marked to his attention addressed to the Commissioner of
Patents and Trademarks, Box 4, Washington, DC 20231.
SUPPLEMENTARY INFORMATION:
I. Discussion of Public Comments
Forty-four comments were received by the Office in response to the
request to public comment on the proposed version of utility guidelines
published on January 3, 1995 (60 FR 97). All comments have been
carefully considered. A number of changes have been made to the
examining guidelines and the legal analysis supporting the guidelines
in response to the comments received.
Many of the individuals responding to the request for public
comments suggested that the Office address the relationship between the
requirements of 35 U.S.C. 112, first paragraph, and 35 U.S.C. 101. The
Office has amended the guidelines to provide a clarification consistent
with these requests. The guidelines now specify that any rejection
based on a ``lack of utility'' under section 101 should be accompanied
by a rejection based upon section 112, first paragraph. The guidelines
also specify that the procedures for imposition and review of
rejections based on lack of utility under section 101 shall be followed
with respect to the section 112 rejection that accompanies the section
101 rejection.
A suggestion was made that the guidelines should be modified to
provide that an application shall be presumed to be compliant with
section 112, first paragraph, if there is no proper basis for imposing
a section 101 rejection. This suggestion has not been followed.
Instead, the guidelines specify that section 112, first paragraph,
deficiencies other than those that are based on a lack of utility be
addressed separately from those based on a lack of utility for the
invention.
Several individuals suggested that the guidelines address how
section 101 compliance will be reviewed for products that are either
intermediates or whose ultimate function or use is unknown. The Office
has amended the guidelines to clarify how it will interpret the
``specific utility'' requirement of section 101.
Some individuals suggested that the guidelines be amended to
preclude Examiners from requiring that an applicant delete references
made in the specification to the utility of an invention which are not
necessary to support an asserted utility of the claimed invention. The
guidelines have been amended consistent with this suggestion.
One individual suggested that the legal analysis be amended to
emphasize that any combination of evidence from in vitro or in vivo
testing can be sufficient to establish the credibility of an asserted
utility. The legal analysis has been amended consistent with this
recommendation.
A number of individuals questioned the legal status of the
guidelines, particularly with respect to situations where an applicant
believes that a particular Examiner has failed to follow the
requirements of the guidelines in imposing a rejection under section
101. The guildeines and the legal analysis supporting the guidelines
govern the internal operations of the Patent and Trademark Office. They
are not intended to, nor do they have the force and effect of law. As
such they are not substantive rules creating or altering the
[[Page 36264]]
rights or obligations of any party. Rather, the guidelines define the
procedures to be followed by Office personnel in their review of
applications for section 101 compliance. The legal analysis supporting
the guidelines articulates the basis for the procedures established in
the guidelines. Thus, an applicant who believes his or her application
has been rejected in a manner that is inconsistent with the guidelines
should respond substantively to the grounds of the rejection. ``Non-
compliance'' with the guidelines will not be a petitionable or
appealable action.
Some individuals suggested that the guidelines and legal analysis
be amended to specify that the Office will reject an application for
lacking utility only in those situations where the asserted utility is
``incredible.'' This suggestion has not been adopted. The Office has
carefully reviewed the legal precedent governing application of the
utility requirement. Based on that review, the Office has chosen to
focus the review for compliance with Section 101 and Section 112, first
paragraph, on the ``credibility'' of an asserted utility.
Some individuals suggested that the guidelines be amended to
address how a generic claim that covers many discrete species will be
assessed with regard to the ``useful invention'' requirements of
sections 101 and 112 when one or more, but not all, species within the
genus do not have a credible utility. The guidelines have been amended
to clarify how the Office will address applications in which genus
claims are presented that encompass species for which an asserted
utility is not credible. The legal analysis makes clear that any
rejection of any claimed subject matter based on lack of utility must
adhere to the standards imposed by these guidelines. This is true
regardless of whether the claim defines only a single embodiment of the
invention, multiple discrete embodiments of the invention, or a genus
encompassing many embodiments of the invention. As cast in the legal
analysis and the guidelines, the focus of examination is the invention
as it has been defined in the claims.
Some individuals questioned whether the guidelines and the legal
analysis govern actions taken by Examining Groups other than Group 1800
or the Board of Patent Appeals and Interferences. The guidelines apply
to all Office personnel, and to the review of all applications,
regardless of field of technology.
In addition to the changes made in response to comments from the
public, the Office has amended the guidelines to clarify the procedure
to be followed when an applicant has failed to identify a specific
utility or an invention. The guidelines now provide that where an
applicant has made no assertion as to why an invention is believed
useful, and it is not immediately apparent why the invention would be
considered useful, the Office will reject the application as failing to
identify any specific utility for the invention. The legal analysis has
also been amended to address evaluation of this question.
II. Guidelines for Examination of Applications for Compliance With the
Utility Requirement
A. Introduction
The following guidelines establish the policies and procedures to
be followed by Office personnel in the evaluation of any application
for compliance with the utility requirements of 35 U.S.C. 101 and 112.
The guidelines also address issues that may arise during examination of
applications claiming protection for inventions in the field of
biotechnology and human therapy. The guidelines are accompanied by an
overview of applicable legal precedent governing the utility
requirement. The guidelines have been promulgated to assist Office
personnel in their review of applications for compliance with the
utility requirement. The guidelines and the legal analysis do not alter
the substantive requirements of 35 U.S.C. 101 and 112, nor are they
designed to obviate review of applications for compliance with this
statutory requirement.
B. Examination Guidelines for the Utility Requirement
Office personnel shall adhere to the following procedures when
reviewing applications for compliance with the ``useful invention''
(``utility'') requirement of 35 U.S.C. 101 and 35 U.S.C. 112, first
paragraph.
1. Read the specification, including the claims, to:
(a) Determine what the applicant has invented, noting any specific
embodiments of the invention;
(b) Ensure that the claims define statutory subject matter (e.g., a
process, machine, manufacture, or composition of matter);
(c) Note is applicant has disclosed any specific reasons why the
invention is believed to be ``useful.''
2. Review the specification and claims to determine if the
applicant has asserted any credible utility for the claimed invention:
(a) If the applicant has asserted that the claimed invention is
useful for any particular purpose (i.e., a ``specific utility'') and
that assertion would be considered credible by a person of ordinary
skill in the art, do not impose a rejection based on lack of utility.
Credibility is to be assessed from the perspective of one of ordinary
skill in the art in view of any evidence of record (e.g., data,
statements, opinions, references, etc.) that is relevant to the
applicant's assertions. An applicant must provide only one credible
assertion of specific utility for any claimed invention to satisfy the
utility requirement.
(b) If the invention has a well-established utility, regardless of
any assertion made by the applicant, do not impose a rejection based on
lack of utility. An invention has a well-established utility if a
person of ordinary skill in the art would immediately appreciate why
the invention is useful based on the characteristics of the invention
(e.g., properties of a product or obvious application of a process).
(c) If the applicant has not asserted any specific utility for the
claimed invention and it does not have a well-established utility,
impose a rejection under section 101, emphasizing that the applicant
has not disclosed a specific utility for the invention. Also impose a
separate rejection under section 112, first paragraph, on the basis
that the applicant has not shown how to use the invention due to lack
of disclosure of a specific utility. The sections 101 and 112,
rejections should shift the burden to the applicant to:
--Explicityly identify a specific utility for the claimed invention,
and
--Indicate where support for the asserted utility can be found in the
specification.
Review the subsequently asserted utility by the applicant using the
standard outlined in paragraph (2)(a) above, and ensure that it is
fully supported by the original disclosure.
3. If no assertion of specific utility for the claimed invention
made by the applicant is credible, and the claimed invention does not
have a well-established utility, reject the claim(s) under section 101
on the grounds that the invention as claimed lacks utility. Also reject
the claims under section 112, first paragraph, on the basis that the
disclosure fails to teach how to use the invention as claimed. The
section 112, first paragraph, rejection imposed in conjunction with a
section 101 rejection should incorporate by reference the grounds of
the corresponding section 101 rejection and should be set out as a
rejection distinct from any other
[[Page 36265]]
rejection under section 112, first paragraph, not based on lack of
utility for the claimed invention.
To be considered appropriate by the Office, any rejection based on
lack of utility must include the following elements:
(a) A prima facie showing that the claimed invention has no
utility.
A prima facie showing of no utility must establish that it is more
likely than not that a person skilled in the art would not consider
credible any specific utility asserted by the applicant for the claimed
invention. A prima facie showing must contain the following elements:
(i) A well-reasoned statement that clearly sets forth the reasoning
used in concluding that the asserted utility is not credible;
(ii) Support for factual findings relied upon in reaching this
conclusion; and
(iii) Support for any conclusions regarding evidence provided by
the applicant in support of an asserted utility.
(b) Specific evidence that supports any fact-based assertions
needed to establish the prima facie showing.
Whenever possible, Office personnel must provide documentary
evidence (e.g., scientific or technical journals, excerpts from
treatises or books, or U.S. or foreign patents) as the form of support
used in establishing the factual basis of a prima facie showing of no
utility according to items (a)(ii) and (a)(iii) above. If documentary
evidence is not available, Office personnel shall note this fact and
specifically explain the scientific basis for the factual conclusions
relied on in sections (a)(ii) and (a)(iii).
4. A rejection based on lack of utility should not be maintained if
an asserted utility for he claimed invention would be considered
credible by a person of ordinary skill in the art in view of all
evidence of record.
Once a prima facie showing of no utility has been properly
established, the applicant bears the burden of rebutting it. The
applicant can do this by amending the claims, by providing reasoning or
arguments, or by providing evidence in the form of a declaration under
37 CFR 1.132 or a printed publication, that rebuts the basis or logic
of the prima facie showing. If the applicant responds to the prima
facie rejection, Office personnel shall review the original disclosure,
any evidence relied upon in establishing the prima facie showing, any
claim amendments and any new reasoning or evidence provided by the
applicant in support of an asserted utility. It is essential for Office
personnel to recognize, fully consider and respond to each substantive
element of any response to a rejection based on lack of utility. Only
where the totality of the record continues to show that the asserted
utility is not credible should a rejection based on lack of utility be
maintained.
If the applicant satisfactorily rebuts a prima facie rejection
based on lack of utility under section 101, withdraw the section 101
rejection and the corresponding rejection imposed under section 112,
first paragraph, per paragraph (3) above.
Office personnel are reminded that they must treat as true a
statement of fact made by an applicant in relation to an asserted
utility, unless countervailing evidence can be provided that shows that
one of ordinary skill in the art would have a legitimate basis to doubt
the credibility of such a statement. Similarly, Office personnel must
accept an opinion from a qualified expert that is based upon relevant
facts whose accuracy is not being questioned; it is improper to
disregard the opinion solely because of a disagreement over the
significance or meaning of the facts offered.
