          Application 08/285,324                                                      

          label, MPEP § 804 (7th ed. July 1998), pages 800-21 through                 
          800-23.                                                                     
               The first condition is satisfied as we show by                         
          comparing claims 1 and 4 of the present application with                    
          claim 1 of the '821 patent (note that we use the claims).                   
          The analysis is the same for the '328 application.  Claim 4                 
          of the present application recites that step (a) of claim 1                 
          comprises the three substeps (a1), (a2), and (a3).  This                    
          appears to be an obvious error because steps (a1)-(a3) have                 
          nothing to do with assigning an image characteristic.                       
          Apparently, claim 4 should refer to step (b) and we analyze                 
          the claims according to this interpretation; i.e.,                          
          steps (a1)-(a3) should be labeled (b1)-(b3).  Then we note                  
          the following correspondence between limitations and assign                 
          the letters to the limitations, where "--" indicates there                  
          is no corresponding limitation.                                             

          Present Appl.     '821 patent
