            Appeal No. 2001-2000                                                      
            Application No. 08/964,096                                                

                                       OPINION                                        
                 We reverse.                                                          
                 Each of independent claims 18, 24 and 30 on appeal in                
            some manner recite a feature of migrating an object of an                 
            object-oriented programming system to a modified set of                   
            fields in a persistent version by automatically storing in                
            permanent storage with the migrated object, the initial set               
            of fields unchanged by at least one modification along with               
            any action necessary to change the initial set of fields to               
            the modified set of fields.  It is these features on which                
            appellants persistently argue patentability in the brief and              
            reply brief and with which we agree.                                      
                 As even the title of Anderson reveals, we also find                  
            ourselves in agreement with appellants’ observations at the               
            bottom of page 2 of the reply brief that the examiner and                 
            appellants view the teachings in Anderson as being based                  
            upon techniques that allow manipulation of different                      
            versions of objects.  Appellants continue “this does not                  
            mean that any version of an object in Anderson is stored in               
            permanent storage with a set of indexes for a class that is
