          Appeal No. 2005-0261                                                        
          Application No. 09/682,473                                                  

          reason why the artisan would have turned to Matsumoto to modify             
          the clock signals of Wissell.  Finally, Wissell specifically                
          discloses the generation of clock signals which are quadrature              
          related, yet the examiner proposes to modify Wissell so that the            
          clock signals are 180 degrees out of phase instead of 90 degrees            
          out of phase.  The examiner has offered no logical basis for                
          changing this key feature of the Wissell clock signal generator.
