Appeal No. 1997-3239
Application 08/312,854
We are not inclined to dispense with proof by evidence
when the proposition at issue is not supported by a teaching
in a prior art reference or shown to be common knowledge of
unquestionable demonstration. Our reviewing court requires
this evidence in order to establish a prima facie case. In re
Piasecki, 745 F.2d 1468, 1471-72, 223 USPQ 785, 787-88 (Fed.
Cir. 1984); In re Knapp-Monarch Co., 296 F.2d 230, 232, 132
USPQ 6, 8 (CCPA 1961); In re Cofer, 354 F.2d 664, 668, 148
USPQ 268, 271-72 (CCPA 1966). Furthermore, Our reviewing
court states in In re Piasecki, 745 F.2d at 1472, 223 USPQ at
788, the following:
The Supreme Court in Graham v. John Deere Co., 383
U.S. 1 (1966), focused on the procedural and
evidentiary processes in reaching a conclusion under
Section 103. As adapted to ex parte procedure,
Graham is interpreted as continuing to place the
"burden of proof on the Patent Office which requires
it to produce the factual basis for its rejection of
an application under section 102 and 103". Citing
In re Warner, 379 F.2d 1011,
1016, 154 USPQ 173, 177 (CCPA 1967).
