          Appeal No. 1998-0828                                                        
          Application 08/438,091                                                      

          (1988); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc.,             
          776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert.                
          denied, 475 U.S. 1017 (1986); ACS Hosp. Sys., Inc. v. Montefiore            
          Hosp., 732 F.2d 1572, 1577, 221 USPQ 929, 933 (Fed. Cir. 1984).             
          These showings by the examiner are an essential part of complying           
          with the burden of presenting a prima facie case of obviousness.            
          Note In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444               
          (Fed. Cir. 1992).  If that burden is met, the burden 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 Id.; 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).  Only those arguments            
          actually made by appellants have been considered in this                    
          decision.  Arguments which appellants could have made but chose             
          not to make in the brief have not been considered and are deemed            
          to be waived by appellants [see 37 CFR § 1.192(a)].                         
          With respect to the rejection of dependent claim 23 based                   
          on Mori and Nihei, since Nihei does not overcome the deficiencies           
          in Mori discussed above with respect to the anticipation                    
                                         -9-
