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, 177 (CCPA 1967), cert.
denied, 389 U.S. 1057 (1968). Our reviewing court has repeatedly cautioned against
employing hindsight by using the appellant's disclosure as a blueprint to reconstruct the
claimed invention from the isolated teachings of the prior art. See, e.g., Grain
Processing Corp. v. American Maize-Prods. Co., 840 F.2d 902, 907, 5 USPQ2d
1788, 1792 (Fed. Cir. 1988).
When determining obviousness, “the [E]xaminer can satisfy the burden of
showing obviousness of the combination ‘only by showing some objective teaching in
the prior art or that knowledge generally available to one of ordinary skill in the art would
lead that individual to combine the relevant teachings of the references.’” In re Lee,
277 F.3d 1338, 1343, 61 USPQ2d 1430, 1434 (Fed. Cir. 2002), citing In re Fritch,
