          Appeal No. 1997-0858                                                        
          Application No. 08/323,065                                                  

          Specifically, it is the examiner's conclusion that it would                 
          have been obvious to provide the Harada process with a                      
          pressure differential between                                               





          the substrate region and the evaporation source region in view              
          of                                                                          
          DeLozanne's teaching.  Central to the examiner's rejection,                 
          however, is the implicit proposition that the ordinarily                    
          skilled artisan would have found it obvious to use the                      
          pressure differ-ential concept taught by DeLozanne but not the              
          specific pressures taught by DeLozanne since these pressures                
          do not correspond to those here claimed.  Instead, the                      
          examiner concludes that it would have been obvious for the                  
          artisan in applying DeLozanne's pressure differential concept               
          to Harada's process to employ as a background pressure (such                
          as the pressure in the evaporation source region) the specific              
          pressure taught by Wang.  As for the appellant's claimed                    
          pressure in the substrate region, it is significant that none               
          of the here applied references explicitly teach a substrate                 

                                          4
