          Appeal No. 1999-1753                                                        
          Application No. 08/515,815                                                  


               The entire thrust of Stedman is the provision of a                     
          mechanism adapted for grasping and moving irregularly shaped,               
          fragile material such as refuse in plastic bags (column 1,                  
          lines 33-38).  To this end, a highly specialized grasping                   
          mechanism is provided having flexible, deformable, resilient                
          jaws that are substantially unbacked so that they may deform                
          to the shape of the plastic bag as the jaws are closed around               
          thereabout (column 1, lines 48-57).  It would not have been                 
          obvious to one of ordinary skill in the art to replace the                  
          grasping mechanism of Stedman with the mechanized grabber                   
          means of Holtom because it would be completely contrary to                  
          Stedman’s objective and make Stedman’s device unsuitable for                
          its intended purpose.  Ex parte Rosenfeld, 130 USPQ 113, 115                
          (Bd. App. 1961).  Moreover, the examiner’s proposed                         
          combination would involve not merely a straightforward                      
          substitution of one grasping means for another, but would                   
          entail a substantial reworking of the interface between the                 
          articulated arm and the grasping means of Stedman to ensure                 
          that the substituted grabber means may “tip” the container as
