            Appeal No. 2003-1610                                                          Page 3              
            Application No. 09/715,128                                                                        


                   Rather than reiterate the conflicting viewpoints advanced by the examiner and              
            the appellant regarding the above-noted rejection, we make reference to the answer                
            (Paper No. 11, mailed November 15, 2002) for the examiner's complete reasoning in                 
            support of the rejection, and to the brief (Paper No. 10, filed October 15, 2002) and             
            reply brief (Paper No. 13, filed January 15, 2003) for the appellant's arguments                  
            thereagainst.                                                                                     


                                                  OPINION                                                     
                   In reaching our decision in this appeal, we have given careful consideration to            
            the appellant's specification and claims, to the applied prior art references, and to the         
            respective positions articulated by the appellant and the examiner.  Upon evaluation of           
            all the evidence before us, it is our conclusion that the evidence adduced by the                 
            examiner is insufficient to establish a prima facie case of obviousness with respect to           
            the claims under appeal.  Accordingly, we will not sustain the examiner's rejection of            
            claims 3 to 10 under 35 U.S.C. § 103.  Our reasoning for this determination follows.              


                   In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden           
            of presenting a prima facie case of obviousness.  See In re Rijckaert, 9 F.3d 1531,               
            1532, 28 USPQ2d 1955, 1956 (Fed. Cir. 1993).  A prima facie case of obviousness is                
            established by presenting evidence that would have led one of ordinary skill in the art to
