          Appeal No. 2000-1540                                                        
          Application No. 09099,617                                                   


               If one could show that Nickerson discloses a situation                 
          wherein there might be only one block in a frame, then there                
          would be prior art against which we could apply the examiner’s              
          interpretation.  But, as it stands, the examiner’s position                 
          appears to rely solely on appellants’ own claim as a “prior art”            
          reference applied against the claim.  That is, the examiner uses            
          the term, “at least one block” to somehow show that the prior art           
          recognized that only one block per frame may be employed and we             
          simply have nothing on the record to show that.  Moreover, the              
          examiner’s interpretation appears to excise the claim limitation            
          regarding the target block bit rate being “selected in accordance           
          with a mean absolute difference (Mad) of said block” because,               
          under the examiner’s interpretation, it would be immaterial as to           
          how the target block bit rate is selected.  It appears to us that           
          we would need to somehow ignore this specific claim language                
          regarding the mean absolute difference if we adopted the                    
          examiner’s rationale.  Unless there is some good and sufficient             
          reason for ignoring a specific claim limitation, e.g., a process            
          limitation in a product-by-process claim, each and every claim              
          limitation must be given weight when applying a rejection under             
          35 U.S.C. 102.                                                              


                                         -6–
