                Appeal 2007-0008                                                                                 
                Application 09/818,023                                                                           
                       material displacement and material stretching that can occur during                       
                       folding because of the double material thickness at the points of                         
                       overlap (Seufert ‘916, col. 1, ll. 37-40).  Seufert addresses this                        
                       problem by forming thinned-down areas 17 in the foil blank prior to                       
                       gluing the foil blank to the cardboard blank (Seufert, col. 2, ll. 57-60).                
                       The thinned-down areas 17 in the foil are formed simultaneously with                      
                       the placement of bend lines 13 in the foil (Seufert ‘916, col. 8,                         
                       ll. 25-29).  The thinned-down areas 17 and bend lines 13 can be                           
                       formed with a high frequency process or with a hot stamping process,                      
                       both of which processes are characterized by Seufert ‘916 as being so                     
                       well known that no further explanation thereof is necessary (Seufert                      
                       ‘916, col. 8, ll. 29-41).                                                                 
                   6. A transition zone between the thin bend line 13 and the wider thinned-                     
                       down area 17 having a gradually increasing width from the thin bend                       
                       line 13 to the wider thinned-down area 17 is illustrated in Figs. 2, 3,                   
                       and 4 of Seufert ‘916. The edge of the extra foil ply (the overlap area)                  
                       is located within the transition zone (Seufert ‘916, Figs. 2, 3, and 4)                   
                   7. Seufert ‘206 discloses use of a rule-shaped tool 20 in the type of high                    
                       frequency process alluded to by Seufert ‘916 (Finding of Fact 5) for                      
                       forming fold lines in carton material.  Seufert ‘206 is the US                            
                       equivalent of the German application (“DE-PS No. 25 41 324”)                              
                       referred to by Seufert ‘916 in disclosing a suitable high frequency                       
                       process for forming the thinned-down areas 17 and bend lines 13 of                        
                       the foil (Seufert ‘916, col. 8, l. 38).  Thus, the process and tooling                    
                       disclosed by Seufert ‘206 are capable of forming the configuration of                     
                       the thinned-down areas 17 and bend lines 13 disclosed by Seufert                          

                                                       6
