          Appeal No. 2000-2247                                                        
          Application 08/137,189                                                      

          current field.  Further, the figure 8 embodiment compares                   
          similarly situated pixel data in prior fields, i.e., between                
          blocks of a current field to blocks at the same location in a               
          prior field, and not to blocks in a closest vicinity of the                 
          current block.  Even if one were to modify figure 8 to compare a            
          current block to blocks within a range as taught in connection              
          with figure 4, this would still not meet the limitation of                  
          comparing a current block of a current image to reconstructed               
          blocks of the same current image, as claimed.                               
               Because Krause does not disclose coding of a difference                
          between a current block of a current image to be transmitted and            
          a reconstructed block of the same current image, the Examiner               
          erred in the finding of anticipation.  The rejection of claims 1            
          and 3-7 is reversed.
