              Appeal No. 1997-0562                                                                                      
              Application No. 08/255,130                                                                                


                                                       OPINION                                                          

                     In reaching our decision in this appeal, we have given careful consideration to the                
              appellants' specification and claims, to the applied prior art references, and to the                     
              respective positions articulated by the appellants and the examiner.  As a consequence of                 
              our review, we make the determinations which follow.                                                      
                     When it is necessary to select elements of various teachings in order to form the                  
              claimed invention, we ascertain whether there is any suggestion or motivation in the prior                
              art to make the selection made by the appellants.  Obviousness cannot be established by                   
              combining the teachings of the prior art to produce the claimed invention, absent some                    
              teaching, suggestion or incentive supporting the combination.   The extent to which such                  
              suggestion must be explicit in, or may be fairly inferred from the references, is decided on              
              the facts of each case, in light of the prior art and its relationship to the appellants'                 
              invention.  As in all determinations under 35 U.S.C.                                                      
              § 103, the decision maker must bring judgment to bear.  It is impermissible, however,                     
              simply to engage in a hindsight reconstruction of the claimed invention, using the                        
              appellants' structure as a template and selecting elements from references to fill the gaps.              
              The references themselves must provide some teaching whereby the appellants'                              
              combination would have been obvious.  In re Gorman, 933 F.2d 982, 986, 18 USPQ2d                          

              1885, 1888 (Fed. Cir. 1991) (citations omitted).  That is, something in the prior art as a                


                                                           4
