          Appeal No. 2003-0052                                                        
          Application No. 09/782,268                                                  

               Under these circumstances, we share the examiner’s                     
          conclusion that it would have been prima facie obvious for an               
          artisan to practice the method of Fifolt at pressures of the type           
          here claimed (e.g., see appealed claims 1-4 and 7) which are                
          above atmospheric pressure.  In support of his contrary view, the           
          appellant states that, “[i]n Example 1 (col. 2, lines 46-57), the           
          effluent from the reaction was trapped in a metal trap cooled               
          with dry ice and ethanol” and that “[t]his is considered vacuum             
          conditions” (brief, page 2).  However, the appellant has                    
          proffered no evidence in support of his last quoted conclusion.             
          Further, as noted by the examiner in his answer, the conditions             
          in patentee’s trap would not create a vacuum in the reaction zone           
          unless a closed system were utilized and the Fifolt reference               
          contains no disclosure of a closed system.  For these reasons, we           
          discern no persuasive merit in the appellant’s argument that the            
          examiner has failed to establish a prima facie case of                      
          obviousness.                                                                
               As further support for his nonobviousness position, the                
          appellant refers to data in the subject specification which is              
          characterized as showing unexpected results that rebut a prima              
          facie case of obviousness.  This data appears on specification              



                                          4
