         Appeal No. 1998-0340                                                     
         Application 08/449,682                                                   


         either expressly or under the principles of inherency, each              
         and every element of a claimed invention.  See RCA Corp. v.              
         Applied Digital Data Sys., 730 F.2d 1440, 1444, 221 USPQ 385,            
         388 (Fed. Cir. 1984).  While applying the test of obviousness,           
         we keep in mind the guidelines of our reviewing court.  The              
         pertinent general proposition is that in an appeal involving a           
         rejection under 35 U.S.C. § 103, an examiner is under a burden           
         to make out a prima facie case of obviousness.  If that burden           
         is met, the burden of going forward then shifts to the                   
         applicant 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, 1052, 189 USPQ 143,            
         147 (CCPA 1976).                                                         
                        Rejection of under 35 U.S.C. § 102                        
              Claims 1-3, 5, 6, 8 and 9 are rejected as being                     
         anticipated by Inaba.  We take for our analysis independent              
                                        4
