          Appeal No. 1996-3126                                                        
          Application No. 08/300,586                                                  


          § 1.192(c)(7) as to the separate patentability of each, except              
          for claims 53 and 21.  Since appellants' sole argument for                  
          claims 53 and 21 refers to the arguments for claim 52, we will              
          consider claims 21, 52, and 53 together.  Thus, we will treat               
          the claims according to the following six groups: (1) claims                
          21, 52, and 53, (2) claims 2 and 22, (3) claims 3 and 23, (4)               
          claims 5 and 25, (5) claims 35 and 54, and (6) claims 38 and                
          55, with claims 52, 2, 3, 5, 54, and 55, respectively, as                   
          representative.                                                             
               We have carefully considered the claims, the applied                   
          prior art references, and the respective positions articulated              
          by appellants and the examiner.  As a consequence of our                    
          review, we will affirm the anticipation rejection of claims                 
          21, 52, and 53 and reverse the anticipation rejections of 2,                
          3, 5, 22, 23, 25, 35, 38, 54, and 55.                                       
               Appellants contend (Brief, pages 5-6) that Sokal's                     
          disclosure teaches away from the claimed invention, and                     
          therefore cannot anticipate the claims.  Appellants refer to                
          the affidavit of Mr. Nathan O. Sokal (one of the inventors of               
          the Sokal patent), filed May 18, 1996, as support for their                 
          position.  We agree that Sokal's invention is contrary to                   
                                          4
