              Appeal No. 2000-0930                                                                                     
              Application No. 08/888,339                                                                               


              paragraph erroneously indicated claims 25 and 27 as being reversed, but it was clear                     
              from the text of the decision at page 6 that we sustained the examiner’s rejection based                 
              upon our finding of an aperture stop in Vogeley.                                                         
                                                   BACKGROUND                                                          
                     The appellant's invention relates to a catadioptric lens system for a scanning                    
              device.  An understanding of the invention can be derived from a reading of exemplary                    
              claim 1, which is reproduced below.                                                                      
              1.     An optical assembly for a photoelectric imaging apparatus in which a light path                   
              extends between an object which is to be imaged and a photosensor array, said optical                    
              assembly comprising:                                                                                     
                     said photosensor array;                                                                           
                     at least one optical component arranged along said light path;                                    
                     said at least one optical component including a lens; and                                         
                     wherein said lens comprises a catadioptric lens.                                                  

                     The prior art reference of record relied upon by the examiner in rejecting the                    
              appealed claims is:                                                                                      
              Vogeley                           4,003,642                          Jan.18, 1977                        
                     Claims 1-4 and 12-16 were rejected under 35 U.S.C. § 103 as being anticipated                     
              by Vogeley.  Claims 5-11 and 17-28 were rejected under 35 U.S.C. § 103 as being                          
              unpatentable over Vogeley.                                                                               


                                                          2
