          Appeal No. 1999-2252                                                        
          Application 08/780,790                                                      


          221 USPQ 1125, 1127 (Fed. Cir. 1984).  However, "[o]bviousness              
          may not be established using hindsight or in view of the                    
          teachings or suggestions of the invention."  Para-Ordnance                  
          Mfg. v. SGS Importers Int’l, 73 F.3d at 1087, 37 USPQ2d at                  
          1239, citing W.L. Gore & Assocs., Inc. v. Garlock, Inc. 721                 
          F.2d at 1553, 220 USPQ at 312-13.                                           
               We agree with Appellants that the Examiner has failed to               
          set forth a prima facie case.  The Examiner must establish why              
          one having ordinary skill in the art would have been led to                 
          the claimed invention by the express teachings or suggestions               
          found in the prior art, or by implications contained in such                
          teachings or suggestions.  The references of record fail to                 
          provide express teachings or suggestions to make the                        
          combinations suggested by the Examiner.                                     
               Therefore, we will not sustain the rejection of Claims 1-              
          2, 4-7, 9-11, 13, 14 and 16 stand rejected under 35 U.S.C. §                
          103 as being unpatentable over Appellants' admitted prior art               
          in view of Aichelmann.                                                      





                                         13
