          Appeal No. 1996-3729                                                        
          Application No. 08/253,839                                                  

          facie case of obviousness which is not outweighed by evidence               
          relied upon by appellants.  Accordingly, we shall affirm the                
          rejection at issue.                                                         
               As noted by the examiner, Saito discloses polyamide                    
          compositions inclusive of appellants' claimed formulation.                  
          Thus, the polyamide resin in the Saito composition may include              
          a polyphthalamide.  Additionally, the Saito composition                     
          contains a modified block copolymer.  Appellants acknowledge                
          in their Brief (page 6) that the modified block copolymer                   
          component of Saito is inclusive of appellants' succinic                     
          anhydride-functionalized block copolymer.  Also, Saito                      
          contemplates inclusion of other components and, in particular,              
          fillers and reinforcement materials (column 7, lines 61-65).                
          We have little doubt that those of ordinary skill in the art                
          would have found it prima facie obvious to include glass or                 
          carbon fibers in the Saito composition, as recited in                       
          appellants' claims, inasmuch as such fibers are conventionally              
          used in the art as fillers or reinforcing agents as evidenced               
          by Taubitz and Koch.                                                        
               Appellants argue that they have supplied data to                       
          demonstrate that addition of modified block copolymers to
