          Appeal No. 2004-0442                                                        
          Application No. 09/222,953                                                  

          evidence of obviousness, we cannot sustain the obviousness                  
          rejection of claims 5, 10, 16, and 21.                                      
               Regarding the obviousness rejection of claims 2, 3, 7, 8, 12           
          through 15, 18, and 19, Ito does not overcome the shortcomings of           
          Ono for the limitations of the independents claims.  Further, as            
          pointed out by appellant (Brief, page 12) the examiner has not              
          pointed to any teaching or suggestion in Ito for modifying Ono to           
          include multiplexors.  Although Ito may disclose multiplexors,              
          there must be some suggestion in the prior art to motivate the              
          skilled artisan to use Ito's multiplexors in Ono's device, and              
          the examiner has pointed to no such teaching or suggestion.                 
          Accordingly, we cannot sustain the obviousness rejection of                 
          claims 2, 3, 7, 8, 12 through 15, 18, and 19.                               

                                     CONCLUSION                                       
               The decision of the examiner rejecting claims  1, 4, 6, 9,             
          11, 17, and 20 under 35 U.S.C. § 102(b) is reversed.  The                   






                                          7
