          Appeal No. 2004-0119                                                        
          Application 08/644,170                                                      


          in a single jaw closing operation, we see no teaching, suggestion           
          or motivation in the remaining references applied by the examiner           
          which would have led one of ordinary skill in the art to then               
          consider forming the crimping tool of Mino from a relatively soft           
          metal like aluminum, thereby creating a problem situation which             
          would subsequently also require a dense anodic coating to be                
          applied on the outer surfaces of the aluminum tool to enhance               
          wear properties thereof.  As urged by appellants in their brief             
          and reply brief, none of the references applied by the examiner             
          would have led one of ordinary skill in the art at the time of              
          appellants’ invention to make a tool with wear susceptible                  
          elements like those in the crimper of Mino out of aluminum.                 
          Instead, it appears that the prior art would have led the                   
          ordinarily skilled worker to use a known hard material, such as             
          steel, for such a tool, or at least for the wear susceptible                
          elements thereof.                                                           


          In our view, the examiner’s position in this appeal                         
          represents a clear case of impermissible hindsight reconstruction           
          of the claimed invention based on appellants’ own teachings.  In            
          that regard, we note, as our court of review indicated in                   
          In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1783 (Fed.               
                                          7
