          Appeal No. 2005-2230                                                        
          Application No. 10/120,307                                                  

          14, filed August 19, 2004) and Reply Brief (filed December 15,              
          2004) for appellants' arguments thereagainst.                               

                                       OPINION                                        
               We have carefully considered the claims, the applied prior             
          art references, and the respective positions articulated by                 
          appellants and the examiner.  As a consequence of our review, we            
          will reverse the anticipation rejection of claims 21 and 39 and             
          also the obviousness rejection of claims 24 and 42.                         
               With regard to claims 21 and 39, the only limitation at                
          issue is the marking of the video/audio signal for later                    
          searching.  The examiner contends (Answer, page 4) that Rangan's            
          statement on page 1402 that "[a]ny part of the bar (i.e., video             
          rope) can be selected and played back, moved, copied or deleted,"           
          suggests that the captured audio/video signals are marked such              
          that they can be searched later to access a selected portion.               
          The examiner further states (Answer, page 6) that laser disc                
          storage (which is used by Rangan) "inherently . . . has some type           
          of marking or index so that data can be directly accessed."                 
          Last, the examiner asserts (Answer, page 7) that Rangan's                   
          creation of a video rope is equivalent to the marking of selected           
          portions.                                                                   
                                          3
