I. 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 Examiners when examining applications for compliance with the
utility requirement of 35 U.S.C.    101. 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.

B. Guidelines for Examination of Applications for Compliance With 35
U.S.C.    101

   Examiners must adhere to the following procedures when examining
applications for compliance with 35 U.S.C.    101.

1. Determine what the applicant has claimed as his or her invention. This
is done to:

   a) ensure that the applicant has claimed statutory subject matter
(e.g., a process, a machine, a composition or a manufacture); and

   b) ascertain what the invention is for purposes of determining whether
it is "useful."

2. Review the specification and claims to determine if the applicant has
disclosed or asserted or any credible utility for the claimed invention.

   a) If the applicant has asserted that the claimed invention is useful
for any particular purpose and that assertion would be considered credible
by a person of ordinary skill in the art, the Examiner should not impose a
rejection based on    101. 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.

   b) If the applicant has not asserted that the claimed invention is
useful for a particular purpose but such a use would be readily apparent
to a person of ordinary skill in the art, the Examiner should not impose a
rejection under    101.

3. If the applicant has not asserted any credible utility for the claimed
invention or a utility would not be readily apparent to one of ordinary
skill in the art, reject the claims under    101. To be considered
appropriate by the Office, a rejection under    101 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 of ordinary skill in the art would not consider
credible any utility for the claimed invention that has been asserted by
the applicant. Where no utility has been asserted in the disclosure, the
prima facie showing must support a finding that a person of ordinary skill
would not be able to ascertain any use for the claimed invention. A prima
facie showing must contain:

i) a well-reasoned statement by the Examiner that clearly sets forth the
reasoning used in reaching his or her conclusions;

ii) support for factual findings relied upon by the Examiner in reaching
his or her conclusions; and

iii) support for conclusions of the Examiner that evidence provided by the
applicant to support an asserted utility would not be considered
persuasive to a person of ordinary skill in the art.

   b) Evidence that supports any factual assertions relied upon by the
Examiner in establishing the prima facie showing. Whenever possible, the
Examiner must provide documentary evidence that supports the factual basis
of a prima facie showing of no utility (e.g., scientific or technical
journals. excerpts from treatises or books, or U.S. or foreign patents).
If documentary evidence is not available, the Examiner should note this
fact and specifically explain the scientific basis for his or her
conclusions.

4. A rejection under    101 should not be maintained if an asserted
utility for the 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 prima facie showing. Once a response
has been received by the Examiner, he or she should 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 that
the Examiner recognize, fully consider and respond to each substantive
element of any response to a rejection under    101.

   Examiners are reminded that they must treat as true credible statements
made by an applicant or a declarant in the specification or in a
declaration provided under 37 CFR    1.132, unless they can show that one
of ordinary skill in the art would have a rational basis to doubt the
truth of such statements. Thus, not accepting the opinion of a qualified
expert that is based on an appropriate factual record would clearly be
improper.
