                 Application No. 07/809,042                                                                                                             


                          Rather than repeat the arguments of appellants and the                                                                        
                 examiner, we make reference in the briefs  and the answer for             1                                                            
                 the respective details thereof.                                                                                                        





                                                                       OPINION                                                                          
                          We have considered the rejection advanced by the examiner                                                                     
                 and the supporting arguments.  We have, likewise, reviewed the                                                                         
                 appellants’ arguments set forth in the briefs.                                                                                         
                          We reverse.                                                                                                                   
                          In our analysis, we are guided by the general proposition                                                                     
                 that in an appeal involving a rejection under 35 U.S.C. § 103,                                                                         
                 an examiner is under a burden to make out a prima facie case of                                                                        
                 obviousness.  If that burden is met, the burden of going forward                                                                       
                 then shifts to the applicant to overcome the prima facie case                                                                          
                 with argument and/or evidence.  Obviousness is then determined                                                                         
                 on the basis of the evidence as a whole and the relative                                                                               
                 persuasiveness of the arguments.  See In re Oetiker, 977 F.2d
