          Interference 104,530                                                        
          Jurgenson v. Dunfield                                                       
               21.  The examiner in interpreting Dunfield’s involved                  
          claims, determined that the “rigid load beam” is the same as                
          the “rigid region” of the load beam.                                        
               22.  Apparently then, the examiner interprets Dunfield’s               
          claims to mean that a microactuator on the “rigid load beam”                
          is the same as a microactuator on a particular region of a                  
          load beam, e.g. on the rigid region of the load beam.                       
               23.  Neither party disputes that Dunfield’s                            
          microactuator on the “rigid load beam” means a microactuator                
          on a particular region of a load beam, e.g. on the rigid                    
          region of the load beam (Paper 36 at 12-14; Paper 84 at 4;                  
          Paper 86 at 1; Paper 86 at 5; Paper 88 at 2).                               
               24.   The examiner further determined that the                         
          patentable feature of the involved claims was that the                      
          microactuator is on the rigid region of the load beam.                      
          (Dunfield Ex. 1020 at 1 and 4).                                             
               25.  Jurgenson argues that the microactuator on the                    
          rigid load beam, e.g. on the rigid region of the load beam is               
          a material limitation (Paper 86 at 10).                                     
               26.  Jurgenson argues that the limitation is a material                
          one, since during prosecution of Jurgenson’s claims 1 and 17,               
          the examiner did not allow the claims until the claims were                 
          amended to add the limitation that the microactuator is                     
                                        - 9 -
