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

               As to claims 24 and 42, the examiner contends (Answer, page            
          4) that Zellweger discloses marking audio by adding tags.                   
          However, the relied upon portions of Zellweger merely discuss               
          annotating a signal, not marking with searchable tags.  Thus,               
          neither Rangan nor Zellweger discloses marking the signals for              
          later searching by adding tags.  Consequently, we cannot sustain            
          the obviousness rejection of claims 24 and 42.
