Appeal No. 96-1489 Application 08/139,876 conclusion, not merely per se rules, which rationale the examiner has not persuasively argued to us. The prior art relied upon by itself does not suggest the desirability of the proposed modification. In re Fritch, 972 F.2d 1260, 1266, 23 F.2d 1780, 1783-84 (Fed. Cir. 1992). In order for us to sustain the examiner’s rejection under 35 U.S.C. § 103, we would need to resort to speculation or unfounded assumptions or rationales to supply deficiencies in the factual basis of the rejection before us. In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968), rehearing denied, 390 U.S. 1000 (1968). In view of the foregoing, the decision of the examiner rejecting claims 1-6 under 35 U.S.C. § 103 is reversed. REVERSED JAMES D.
