By Kevin E. Noonan --
The U.S. Patent and Trademark Office promulgated today
its long-awaited guidelines for Examiners in making obviousness determinations
in view of the U.S. Supreme Court's decision in KSR Int'l Co. v. Teleflex Inc.
The guidelines generally follow the Patent Office's
public comments on the decision (see "The Patent Office Reacts to KSR: A First Look"), to the effect that KSR merely reinforced the
primacy of the analytical framework provided in the Supreme Court's Graham v. John
Deere Co. decision. This analysis remains,
as the Office contends it always has been, the proper basis for an Examiner's
obviousness determinations.
One important feature of the guidelines, however, is an
explicit requirement that an Examiner provide articulated reasons for the
factual determinations underlying an asserted prima facie case of
obviousness. This focus is consistent
with the rule set down in the KSR decision that a factfinder must provide
"reasons" why an invention would have been obvious to one of ordinary
skill in the art. In explicating this
aspect of the Supreme Court's decision, the Notice sets forth the following
"rationales" for asserting an obviousness rejection, and sets forth
explicit factual findings that an Examiner must articulate to support an
obviousness rejection made using any of these rationales:
(A) Combining prior art elements according to known
methods to yield predictable results;
(1) a finding that the prior art included each element
claimed, although not necessarily in a single prior art reference, with the
only difference between the claimed invention and the prior art being the lack
of actual combination of the elements in a single prior art reference;
(2) a finding that one of ordinary skill in the art could
have combined the elements as claimed by known methods, and that in
combination, each element merely would have performed the same function as it
did separately;
(3) a finding that one of ordinary skill in the art would
have recognized that the results of the combination were predictable; and
(4) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
(The fourth "prong" is a "catch-all"
provision contained in all the rationales.) This rationale is illustrated by
the factual posture of Anderson's-Black
Rock, Inc. v. Pavement Salvage Co., 396 U.S. 57 (1969) and in Ruiz v. A.B. Chance
Co., 357 F.3d 1270 (Fed. Cir. 2004). The Notice cites KSR for the proposition
that, under this rationale, ''it can be important to identify a reason that
would have prompted a person of ordinary skill in the relevant field to combine
the elements in the way the claimed new invention does." But this rationale also notes that unexpected
results can be used to overcome a prima facie case of obviousness on these fact
patterns, citing U.S. v. Adams, 383 U.S. 39, 51-52 (1969).
(B) Simple substitution of one known element for another
to obtain predictable results;
(1) a finding that the prior art contained a device
(method, product, etc.) which differed from the claimed device by the
substitution of some components (step, element, etc.) with other
components;
(2) a finding that the substituted components and their
functions were known in the art;
(3) a finding that one of ordinary skill in the art could
have substituted one known element for another, and the results of the substitution would have been predictable; and
(4) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
This rationale is illustrated by the factual posture
of In re Fout, 675 F.2d 297 (C.C.P.A. 1982); In re O'Farrell, 853 F.2d 894 (Fed. Cir. 1988);
Ruiz v. A.B. Chance Co. 357 F.3d 1270 (Fed. Cir. 2004); and Ex parte Smith, 83 U.S.P.Q.2d 1509 (B.P.A.I. 2007). Proper application of
this rationale in finding obviousness is that "the substitution of one
known element for another would have yielded predictable results to one of
ordinary skill in the art at the time of the invention."
(C) Use of known technique to improve similar devices
(methods, or products) in the same way;
(1) a finding that the prior art contained a ''base''
device (method, or product) upon which the claimed invention can be seen as an ''improvement;''
(2) a finding that the prior art contained a
''comparable'' device (method, or product that is not the same as the base
device) that was improved in the same way as the claimed invention;
(3) a finding that one of ordinary skill in the art could
have applied the known ''improvement'' technique in the same way to the ''base'' device (method, or product) and the results
would have been predictable to one of ordinary skill in the art; and
(4) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under consideration, to explain a conclusion of
obviousness.
This rationale is illustrated by the factual posture
of In re Nilssen, 851 F.2d 1401 (Fed. Cir. 1988) and Ruiz v. A.B. Chance Co. 357 F.3d 1270 (Fed. Cir. 2004). This rationale requires that the prior art
teach:
a method of enhancing a particular class of devices (methods, or
products) [that] was made part of the ordinary capabilities of one skilled in
the art based upon the teaching of such improvement in other situations. One of
ordinary skill in the art would have been capable of applying this known method
of enhancement to a 'base' device (method, or product) in the prior art and
the results would have been predictable to one of ordinary skill in the
art.
(D) Applying a known technique to a known device (method,
or product) ready for improvement to yield predictable results;
(1) a finding that the prior art contained a ''base''
device (method, or product) upon which the claimed invention can be seen as an
''improvement;''
(2) a finding that the prior art contained a known
technique that is applicable to the base device (method, or product);
(3) a finding that one of ordinary skill in the art would
have recognized that applying the known technique would have yielded
predictable results and resulted in an improved system; and
(4) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
This rationale is illustrated by the factual posture of
Dann v. Johnston, 425 U.S. 219 (1976) and In re Nilssen, 851 F.2d 1401 (Fed. Cir. 1988). The Notice defines the terms "base
device," "known technique," and "improved system" with
regard to this rationale. In applying
this rationale to specific facts, a particular known technique that was
recognized by one of ordinary skill in the art can be considered "as part
of the ordinary capabilities" of the skilled worker. Thus, if the worker of ordinary skill would
have been able to apply the known technique to a known "device" (a
method or product) that was "ready for improvement" and yielded a
predictable result, the resulting invention would have been obvious.
(E) ''Obvious to try'' - choosing from a finite number of
identified, predictable solutions, with a reasonable expectation of success;
(1) a finding that at the time of the invention, there
had been a recognized problem or need in the art, which may include a design
need or market pressure to solve a problem;
(2) a finding that there had been a finite number of
identified, predictable potential solutions to the recognized need or problem;
(3) a finding that one of ordinary skill in the art could
have pursued the known potential solutions with a reasonable expectation of
success; and
(4) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
This rationale is illustrated by the factual posture of
Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348 (Fed. Cir. 2007);
Alza Corp. v. Mylan Laboratories, Inc., 464 F.3d 1286 (Fed.
Cir. 2006); and Ex parte Kubin, 83 U.S.P.Q.2d 1410 (B.P.A.I.
2007) (Patent Docs will have more on the latter application of the rule in a related post). Citing KSR, the Notice requires for this rationale that
an Examiner articulate facts supporting the conclusion that:
a person of
ordinary skill has good reason to pursue the known options within his or her
technical grasp. If this leads to the anticipated success, it is likely the
product not of innovation but of ordinary skill and common sense. In that
instance the fact that a combination was obvious to try might show that it was
obvious under § 103.
(F) Known work in one field of endeavor may prompt
variations of it for use in either the same field or a different one based on
design incentives or other market forces if the variations would have been
predictable to one of ordinary skill in the art;
(1) a finding that the scope and content of the prior
art, whether in the same field of endeavor as that of the applicant's invention
or a different field of endeavor, included a similar or analogous device
(method, or product);
(2) a finding that there were design incentives or market
forces which would have prompted adaptation of the known device (method, or
product);
(3) a finding that the differences between the claimed
invention and the prior art were encompassed in known variations or in a
principle known in the prior art;
(4) a finding that one of ordinary skill in the art, in
view of the identified design incentives or other market forces, could have
implemented the claimed variation of the prior art, and the claimed variation
would have been predictable to one of ordinary skill in the art; and
(5) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
This rationale is illustrated by the factual posture of
Dann v. Johnston, 425 U.S. 219 (1976); Leapfrog Enterprises, Inc. v. Fisher-Price, Inc., 485
F.3d 1157 (Fed. Cir. 2007); Ex parte Catan, 83 U.S.P.Q.2d 1569 (B.P.A.I. 2007); and KSR Int'l Co. v. Teleflex Inc. itself. The Examiner must articulate facts supporting
the existence of "design incentives or other market forces could have
prompted one of ordinary skill in the art to vary the prior art in a
predictable manner to result in the claimed invention."
(G) Some teaching, suggestion, or motivation in the prior
art that would have led one of ordinary skill to modify the prior art reference
or to combine prior art reference teachings to arrive at the claimed invention.
(1) a finding that there was some teaching, suggestion,
or motivation, either in the references themselves or in the knowledge
generally available to one of ordinary skill in the art, to modify the
reference or to combine reference teachings;
(2) a finding that there was reasonable expectation of
success; and
(3) whatever additional findings based on the Graham
factual inquiries may be necessary, in view of the facts of the case under
consideration, to explain a conclusion of obviousness.
This, of course, is a recapitulation of the Federal
Circuit's "teaching-suggestion-motivation" test, supplemented with
the Graham-derived catch-all provision this rationale shares with all the
rest. The Notice cites DyStar
Textilfarben GmbH v. C.H. Patrick Co., 464 F.3d 1356 (Fed. Cir. 2006),
for the application of this rationale where the "motivation" is
"technology-independent," such as the "desire to enhance
commercial opportunities" by making a product or process "stronger,
cheaper, cleaner, faster, lighter, smaller, more durable, or more
efficient," calling this motivation "universal" and "almost
common-sensical."
The guidelines impose these enumerated requirements on
Examiners to provide the articulated reasons set forth above when making the
factual findings relating an obviousness determination. The guidelines also remind Examiners of the
requirements of 37 C.F.R. 1.111(b) that applicants rebut these factual
determinations by "distinctly and specifically point[ing] out the supposed
errors in the Office's action and reply to every ground of objection and
rejection in the Office action," as well as the burden to "present
arguments pointing out the specific distinction believed to render the claims
patentable over any applied references." Applicants evidence can include factual evidence that "(1) one of
ordinary skill in the art could not have combined the claimed elements by known
methods (e.g., due to technological difficulties); (2) the elements in
combination do not merely perform the function that each element performs
separately; or (3) the results of the claimed combination were
unexpected," as well as evidence relating to the secondary considerations
enunciated in Graham (long-felt need, commercial success, and failure of
others). The Examiner must then
reconsider the question of non-obviousness in light of all the evidence of
record.
The guidelines generally comport with the Office's assertions
in the immediate wake of the KSR decision that its obviousness determinations
were "business as usual," "status quo," and had always been
based on the Graham factors. Although
this stance was belied by the perceived need to promulgate explicit guidelines
to inform Examiners to continue what was purportedly their conventional
practice, the guidelines generally remain true to the conventional
Graham analysis, supplemented when necessary by the Federal Circuit's TSM test. Clearly gone from the analysis is the
traditional assertion that an obviousness determination would be deficient
merely because it was not supported under the TSM analysis. This result was not dependent on these new
guidelines, however; the Office's position in this regard has been clear for
months, as evidenced by this excerpt from the prosecution history of U.S. Patent Application No. 11/436775:
[I]n response to Applicant's argument that the references
do not provide that a specific teaching, suggestion, or motivation to support a
finding of obviousness, KSR forecloses the argument that a specific teaching,
suggestion, or motivation is required to support a finding of obviousness. See
the recent Board decision Ex parte Smith, USPQ2d, slip op. at 20 (Bd. Pat. App.
& Interf. June 25, 2007) (citing KSR International Co. v. Teleflex Inc.
(KSR), 82 USPQ2sd at 1396).
The ultimate impact of the Supreme Court's KSR decision
will only be evident after Examiners have had a chance to apply the guidelines
to actual claims. Whether KSR evinces a
sea change in how the Office determines obviousness will depend in large part
on the extent to which Examiners are required to provide articulated reasons
for the factual determinations that are not explicitly required.
