          Application No. 07/983,118                                                  


          1051, 5 USPQ2d 1434, 1438 (Fed. Cir.), cert. denied, 488 U.S.               
          825                                                                         
          (1988); Ashland Oil, Inc. v. Delta Resins & Refractories,                   
          Inc.,                                                                       
          776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert.                
          denied, 475 U.S. 1017 (1986); ACS Hosp. Sys., Inc. v.                       
          Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ 929, 933 (Fed.              
          Cir. 1984).  These showings by the Examiner are an essential                
          part                                                                        
          of complying with the burden of presenting a prima facie case               
          of                                                                          
          obviousness.  Note In re Oetiker, 977 F.2d 1443, 1445, 24                   
          USPQ2d                                                                      
          1443, 1444 (Fed. Cir. 1992).                                                
               With respect to claims 34, 39, and 51 (all of the                      
          independent claims on appeal), the Examiner, as the basis for               
          the obviousness rejection, seeks to modify the color display                
          device  of Suntola by relying on Mourey to supply the missing               
          teaching of  providing an offset between adjacent windows in                
          the column of windows of the light gate array.  In the                      
          Examiner’s view, the skilled artisan would have found it                    
                                         10
