                Appeal No. 2006-1690                                                                         
                Application No. 10/154,185                                                                   

                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.  See 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 [see 37 CFR                                      
                § 41.37(c)(1)(vii)(2004)].                                                                   
                      We will sustain the examiner's rejection of claims 4-7, 13, 15, 16, and 24-            
                26.  We find that the examiner has established at least a prima facie case of                
                obviousness of those claims that appellants have not persuasively rebutted.                  
                Here, the examiner has (1) pointed out the teachings of Park, (2) pointed out the            
                perceived differences between Park and the claimed invention, and (3)                        
                reasonably indicated how and why Park would have been modified to arrive at                  
                the claimed invention [answer, pages 6-9].  Once the examiner has satisfied the              
                burden of presenting a prima facie case of obviousness, the burden then shifts to            
                appellants to present evidence or arguments that persuasively rebut the                      

                                                     11
