          Application No. 08/798,718                                                  


          276, 205 USPQ 215, 219 (CCPA 1980) and In re Aller, 220 F.2d                
          454, 456, 105 USPQ 233, 235 (CCPA 1955).  As stated in In re                
          Huang, 100 F.3d 135, 139, 40 USPQ2d 1685, 1688 (Fed. Cir.                   
          1996):                                                                      
               [t]his court and its predecessors have long held,                      
               however, that even though applicant's modification                     
               results in great improvement and utility over the                      
               prior art, it may still not be patentable if the                       
               modification was within the capabilities of one                        
               skilled in the art, unless the claimed ranges                          
               "produce a new and unexpected result which is                          
               different in kind and not merely in degree from the                    
               results of the prior art."                                             

          Additionally, as stated in In re Woodruff, 919 F.2d 1575,                   
          1578, 16 USPQ2d 1934, 1936 (Fed. Cir. 1990):                                
               [t]he law is replete with cases in which the                           
               difference between the claimed invention and the                       
               prior art is some range or other variable within the                   
               claims.  . . .  These cases have consistently held                     
               that in such a situation, the applicant must show                      
               that the particular range is critical, generally by                    
               showing that the claimed range achieves unexpected                     
               results relative to the prior art range [citations                     
               omitted].                                                              



               In the present case, however, the appellant has not even               
          alleged, must less established, that the claimed ratio (i.e.,               
          the length of the line of weakness to the length of one side
