          Appeal No. 2004-1197                                                               
          Application No. 10/041,430                                                         


          Saitoh.  Thus, considering the only prior art before us, the                       
          obviousness rejection on appeal cannot be sustained.                               


                                  REMAND TO THE EXAMINER                                     


                We remand this application to the examiner for the following                 
          reason.                                                                            


                It does not appear in the record that any known methane                      
          detectors that give off audible warnings have been considered.                     


                The examiner should assess broad claim 10, for example, in                   
          light of known methane detectors.                                                  


                In summary, this panel of the Board has not sustained the                    
          obviousness rejection on appeal and has remanded the application                   
          to the examiner for the reason given above.                                        









                                             5
