               Appeal 2007-1908                                                                             
               Application 10/442,950                                                                       

           1   from their origin positions to another cutting knife arrangement, as recited in              
           2   claim 3.                                                                                     
           3                                                                                                
           4                              FINDINGS OF FACT                                                  
           5          We find that the following enumerated findings are supported by at                    
           6   least a preponderance of the evidence.  Ethicon, Inc. v. Quigg, 849 F.2d                     
           7   1422, 1427, 7 USPQ2d 1152, 1156 (Fed. Cir. 1988) (explaining the general                     
           8   evidentiary standard for proceedings before the Office).                                     
           9          1.       Appellant invented a method of switching arrangements of                     
          10          cutting knives to change the slitting width in a slitter for slitting a               
          11          wide sheet into a plurality of narrow strips by a plurality of cutting                
          12          knives arranged at predetermined intervals (Specification 1).                         
          13          From our review of Coburn '495 we make the following findings of                      
          14          fact:                                                                                 
          15          2.    “A corrugator is an integrated group of machines for                            
          16          manufacturing sheets of double face corrugated paperboard and                         
          17          includes a slitter scorer which is conventionally located downstream                  
          18          from a rotary shear and upstream from a cut-off machine.”  (Coburn                    
          19          '495, col. 1, ll. 5-9).                                                               
          20          3.    “The slitter scorer slits the web of double face corrugated board               
          21          longitudinally and scores the web by applying crease lines                            
          22          longitudinally thereon.”  (Coburn '495, col. 1, ll. 9-12).                            
          23          4.    “An upper pair of rotatable slitter shafts is provided                          
          24          downstream from an upper pair of scorer shafts. A lower pair of
