          Appeal No. 97-3824                                                          
          Application 29/042,728                                                      


          back portion of the belt, with the legs of the V extending                  
          from opposite sides of a small centrally disposed rectangular               
          element having a vertical dimension slightly greater than the               
          width of the strap.                                                         
               The examiner explains the case for obviousness as                      
          follows:                                                                    
                    It would have been obvious to one of ordinary                     
               skill in the art at the time the invention was made                    
               to made to modify Yewer, Jr. by providing it with                      
               the overlapped contoured belt . . . as taught by                       
               Schiek, Sr., and the rear tab as taught by Glover et                   
               al[.] to obtain essentially the herein disclosed and                   
               claimed design.  [Answer at 4.]                                        
          Appellant's position is that                                                
               modification of Yewer with selected, dissected                         
               elements of Schiek and Glover et al. would destroy                     
               the belt disclosed by Yewer in that a majority of                      
               the features of Yewer must be modified.  These                         
               modifications clearly destroy the fundamental                          
               characteristics of the design of the Yewer belt.                       
               [Opening Brief at 8.]                                                  
          We agree with appellant and therefore hold that Yewer is not a              
          proper primary reference, which is reason enough to reverse                 
          the rejection.  Rosen, 673 F.2d at 391, 213 USPQ at 350.                    
          Nevertheless, we have also considered whether the collective                
          teachings of the references yield the claimed design.  As                   
          evidence of the obviousness of using appellant's V-shaped                   
                                        - 6 -
