          Appeal No. 2002-1281                                                        
          Application No. 08/857,711                                                  


          references to arrive at the claimed invention.  Such reason must            
          stem from some teachings, suggestions or implications in the                
          prior art as a whole or knowledge generally available to one                
          having ordinary skill in the art.  Uniroyal, Inc. v. Rudkin-Wiley           
          Corp., 837 F.2d 1044, 1051, 5 USPQ2d 1434, 1438 (Fed. Cir.),                
          cert. denied, 488 U.S. 825 (1988); Ashland Oil, Inc. v. Delta               
          Resins & Refractories, Inc., 776 F.2d 281, 293, 227 USPQ 657, 664           
          (Fed. Cir. 1985), cert. denied, 475 U.S. 1017 (1986); ACS Hosp.             
          Sys., Inc. v. Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ               
          929, 933 (Fed. Cir. 1984).  These showings by the examiner are an           
          essential part of complying with the burden of presenting a prima           
          facie case of obviousness.  Note In re Oetiker, 977 F.2d 1443,              
          1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).                                
               We have reviewed the examiner’s rationale for making the               
          rejection under 35 U.S.C. § 103 and we conclude that the examiner           
          has failed to establish the requisite prima facie case of                   
          obviousness.                                                                
               Initially, the examiner notes that APA describes a remote              
          control vehicle starting system with many of the claimed                    
          elements, including a transponder, but the examiner recognizes              
          that APA lacks a selectively operable second transponder for                
          operation with a passive anti-theft system.  Accordingly, the               

                                         -7–
