          Appeal No. 97-2594                                                          
          Application 08/444,389                                                      


          the particular                                                              
          length recited in the claims does not make such modification                
          or construction obvious unless there is some suggestion in the              
          prior art of the desirability of doing so.  In re Fritch, 972               
          F.2d 1260, 1266, 23 USPQ2d 1780, 1783-84 (Fed. Cir. 1992); In               
          re Laskowski, 871 F.2d 115, 117, 10 USPQ2d 1397, 1398 (Fed.                 
          Cir. 1989).  We find no such suggestion in Diggs and therefore              
          will not sustain the rejection.                                             





               The examiner's decision to reject claims 1, 11 and 15 is               
          reversed.                                                                   
                                      Reversed
