reference teachings would appear to be sufficient for one of
ordinary skill in the relevant art having the references
before him to make the proposed combination or other
modification. See In re Lintner, 458 F.2d 1013, 1016, 173
USPQ 560, 562 (CCPA 1972). Furthermore, the conclusion that
the claimed subject matter is prima facie obvious must be
supported by evidence, as shown by some objective teaching in
the prior art or by knowledge generally available to
one of ordinary skill in the art that would have led that
individual to combine the relevant teachings of the references
to arrive at the claimed invention. See In re Fine, 837 F.2d
1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). Rejections
based on
§ 103 must rest on a factual basis with these facts being
interpreted without hindsight reconstruction of the invention
from the prior art. The examiner may not, because of doubt
that the invention is patentable, resort to speculation,
unfounded assumption or hindsight reconstruction to supply
deficiencies in the factual basis for the rejection. See In
re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967),
cert. denied, 389 U.S.
