                                                     DISCUSSION                                                            
                     In reaching our decision in this appeal, we have given consideration to the                           
              appellant's specification and claims, to the applied references, and to the respective                       
              positions articulated by the appellant and the examiner.                                                     
                     Rather than reiterate the conflicting viewpoints advanced by the examiner and                         
              the appellant regarding the noted rejections, we make reference to the examiner’s                            
              Answer for the examiner’s reasoning in support of the rejection, and to the appellant's                      
              Brief and Reply Brief for the appellant's arguments thereagainst.  As a consequence of                       
              our review, we make the determinations which follow.                                                         


              Background                                                                                                   
                     According to the specification (page 6, lines 14-18) the invention includes “the                      
              generation of nucleotide specific, stable isotope 13C/15N/2H-labeled DNA coupled with                        
              analysis of the resulting mass shifts using mass spectroscopy (MS) to determine the                          
              number of each type of the labeled nucleotide.”  The claimed invention (claim 1) is                          

                                                            4
