              Appeal No. 2004-1072                                                               Page 2                
              Application No. 09/868,150                                                                               


                                                   BACKGROUND                                                          
                     The appellant's invention relates to an electromagnetic actuator (specification, p.               
              1).  A copy of dependent claims 8 to 10 is set forth in the appendix to the appellant's                  
              brief.  Claim 7 reads as follows:                                                                        
                            Electromagnetic actuator, having at least one electromagnet (10) that acts                 
                     on a correspondingly designed armature surface (20) of a moveable armature                        
                     (22) in a first effective range (12) by way of at least one first conical and/or                  
                     stepped pole face (18) using a magnetic field (16) generated by at least one coil                 
                     (14), thereby forming a first magnetic flux (48), wherein said first magnetic flux                
                     (48) flows through a first working air gap (60), characterized in that, shortly                   
                     before the moveable armature (22) reaches an end position, the electromagnet                      
                     (10) acts on a corresponding armature surface (28) by way of at least a second                    
                     pole face (26) in at least a second effective range (24), whereby a second                        
                     magnetic flux (58) is formed, wherein said second magnetic flux (58) flows                        
                     through a second working air gap (62).                                                            


                     Claims 7 to 10 stand rejected under 35 U.S.C. § 102(b) as being anticipated by                    
              U.S. Patent No. 4,281,6851 to Uemura.                                                                    


                     Rather than reiterate the conflicting viewpoints advanced by the examiner and                     
              the appellant regarding the above-noted rejection, we make reference to the answer                       
              (Paper No. 12, remailed December 5, 2003) for the examiner's complete reasoning in
