          Appeal No. 96-3093                                                          
          Application 08/046,880                                                      


          argue that the applied prior art, individually or in                        
          combination, does not teach the feature of highlighting only                
          selected ones of the fourth set of options depending on the                 
          selections made from the second and the third sets of options.              
          [Brief, pages 4 to 6].                                                      
               The Examiner responds that, in Crandall, the equivalent                
          "second and third sets of options" are the touchable boxes                  
          (column 7, lines 30 to 34) of the calendar 502 wherein the                  
          invisible/indistinctable (e.g., black background) icon is                   
          activated only when at least one of these boxes is selected.                
          [Answer, page 4].  The Examiner also contends that "Crandall                
          teaches a calendar display system in which when a certain                   
          specific icon (e.g., date box 504) has been selected, . . .                 
          features in the selected icon are highlighted (column 7, lines              
          39 to 43)" [Answer, page 4].                                                
               In rejecting claims under 35 U.S.C. § 103, it is                       
          incumbent upon the examiner to establish a factual basis to                 
          support the legal conclusion of obviousness.  See In re Fine,               
          837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988).  In              
          so doing, the examiner is expected to make the factual                      
          determinations set forth in Graham v. John Deere Co., 383 U.S.              
                                         -5-
