Appeal No. 96-2383 Application 08/217,418 To sustain the examiner's rejection, we would need to resort to speculation or unfounded assumptions to supply the factual deficiencies in the record before us. This we decline to do. Note the guidance provided by In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968), reh'g denied, 390 U.S. 1000 (1968). Here, simply put, more evidence is needed to convince us. To the extent the examiner's position may be viewed as being based upon inherency, inherency may not be established by probabilities or possibilities since inherency requires a teaching must be necessarily present in the applied prior art. Continental Can Co. v. Monsanto Co., 948 F.2d 1264, 1269, 20 USPQ2d 1746, 1749 (Fed. Cir. 1991) relying on In re Oelrich, 666 F.2d 578, 581, 212 USPQ 323, 326 (CCPA 1981). These findings are consistent with a more recent case from our reviewing court, In re Robertson, ___ F.3d ___, 49 USPQ2d 1949 (Fed. Cir. 1999). In view of the foregoing, the decisions of the examiner rejecting various claims under 35 U.S.C. § 102 and § 103 are reversed. 7Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
