          Appeal No. 2005-0998                                                        
          Application No. 10/054,605                                                  

               The prior art references relied upon by the examiner are:              
          Zhao et al. (Zhao)            5,674,787             Oct.  7, 1997           
          Dubin et al. (Dubin)          5,695,810             Dec.  9, 1997           
          Hong et al. (Hong)            6,077,774             Jun. 20, 2000           
          Lee et al. (Lee)              6,180,523             Jan. 30, 2001           
          Maydan et al. (Maydan)        6,372,633             Apr. 16, 2002           
               All of the appealed claims stand rejected for obviousness              
          under 35 U.S.C. § 103(a).  The examiner has chosen to present the           
          case for obviousness in terms of five separate rejections.  With            
          respect to each rejection, the claims, and the references applied           
          against those claims, are grouped as follows:                               
               1.   Claims 1-4 and 18-21 (Dubin in view of Hong).                     
               2.   Claims 1, 9-10, 18, and 26-27 (Maydan in view of Hong).           
               3. Claims 1-2 and 18-19 (Lee in view of Hong).                         
               4.   Claims 5, 7, 22 24, and 37-38 (Dubin in view of Hong              
          and Zhao).                                                                  
               5. Claims 8, 25 and 35-36 (Lee in view of Hong and Zhao).              
               We have carefully considered the entire record in light of             
          the opposing positions taken by the appellants and by the                   
          examiner.  Having done so, we conclude that each combination of             
          references relied upon by the examiner supports a prima facie               
          case of obviousness with respect to the rejected claims.                    
          Accordingly, we shall affirm all of the rejections at issue for             
          the following reasons:                                                      
                                          3
