          Appeal No. 1998-2725                                                        
          Application 08/473,651                                                      


          eliminating any of the descriptions of areas covered by                     
          objects during the course of processing.  Seki simply                       
          indicates that certain areas will be visible or hidden by the               
          use of flags, but Seki never removes any of the data                        
          descriptive of the area covered by an object.  Therefore, the               
          modifying step as recited in claims 19 and 20 is not taught or              
          suggested by Seki.  Foley provides nothing to overcome this                 
          deficiency in Seki.                                                         
          Since the examiner has failed to properly address all                       
          the limitations of claims 19 and 20, the examiner has failed                
          to establish a prima facie case of the obviousness of these                 
          claims.  Therefore, the decision of the examiner rejecting                  
          claims 19 and 20 is reversed.                                               
          REVERSED
