          Appeal No. 95-3582                                                          
          Application 08/179,419                                                      


          a modification would have been obvious.  Instead, it is well                
          settled that in order to establish a prima facie case of                    
          obviousness the prior art teachings must be sufficient to                   
          suggest to one of ordinary skill in the art making the                      
          modification needed to arrive at the claimed invention.  See,               
          e.g., In re Lalu, 747 F.2d 703, 705, 223 USPQ 1257, 1258 (Fed.              
          Cir. 1984).  The examiner, however, has provided no factual                 
          basis whatsoever for concluding that the modification proposed              
          would have been obvious.  See, e.g., In re GPAC Inc, 57 F.3d                
          1573, 1582,                                                                 
          35 USPQ2d 1116, 1123 (Fed. Cir. 1995) and In re Warner, 379                 
          F.2d 1011, 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied,               
          389 U.S. 1057 (1968).                                                       
               As the examiner apparently recognizes, there is nothing                
          in Wismer or Raiken (additionally relied on in the rejection                
          of claims 26-34) which would overcome the deficiencies of                   
          Honkanen.                                                                   







                                          7
