          Appeal No. 2000-2255                                                        
          Application No. 09/123,522                                                  

          a prima facie case of obviousness.  If that burden is met, the              
          burden of going forward then shifts to Appellant to overcome the            
          prima facie case with argument and/or evidence.  Obviousness is             
          then determined on the basis of the evidence as a whole and the             
          relative persuasiveness of the arguments.  See In re Oetiker, 977           
          F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992); In re               
          Hedges, 783 F.2d 1038, 1039, 228 USPQ 685, 686 (Fed. Cir. 1986);            
          In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ 785, 788 (Fed. Cir.           
          1984); and In re Rinehart, 531 F.2d 1048, 1051-52, 189 USPQ 143,            
          147 (CCPA 1976).                                                            
               With respect to independent claims 1, 6, and 11, and                                                                     
          dependent claim 7, after reviewing the Examiner’s analysis set              
          forth at page 4 of the Answer, it is our view that such analysis            
          carefully points out the teachings of the Newton and Zaitsu                 
          references, reasonably indicates the perceived differences                  
          between this prior art and the claimed invention, and provides              
          reasons as to how and why the prior art teachings would have been           
          modified and/or combined to arrive at the claimed invention.  In            
          our opinion, the Examiner's analysis is sufficiently reasonable             
          that we find that the Examiner has at least satisfied the burden            
          of presenting a prima facie case of obviousness.  The burden is,            
          therefore, upon Appellant to come forward with evidence and/or              
                                          4
