Appeal No. 1999-0424
Application 08/298,552
arguments set forth in the briefs along with the examiner’s
rationale in support of the rejections and arguments in
rebuttal set forth in the examiner’s answer.
It is our view, after consideration of the record
before us, that the evidence relied upon and the level of
skill in the particular art would not have suggested to one of
ordinary skill in the art the obviousness of the invention as
set forth in the claims on appeal. Accordingly, we reverse.
In rejecting claims under 35 U.S.C. § 103, it is
incumbent upon the examiner to establish a factual basis to
support the legal conclusion of obviousness. See In re Fine,
837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). In
so doing, the examiner is expected to make the factual
determinations set forth in Graham v. John Deere Co., 383 U.S.
1, 17, 148 USPQ 459, 467 (1966), and to provide a reason why
one having ordinary skill in the pertinent art would have been
led to modify the prior art or to combine prior art references
to arrive at the claimed invention. Such reason must stem
from some teaching, suggestion or implication in the prior art
