                Appeal No. 2006-1149                                                                                               
                Application No. 10/296,406                                                                                         

                Royka, 490 F.2d 981, 180 USPQ 580 (CCPA 1974).                                                                     
                        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 appellant have been considered in this decision.  Arguments which                                 
                appellant 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 consider first the examiner’s rejection of claims 10-17, 19, and 20 that stand                          
                rejected under 35 U.S.C. § 103(a) as being unpatentable over the teachings of Muzslay in                           
                view of Zinn.  Since appellant’s arguments with respect to this rejection have treated these                       
                claims as a single group which stand or fall together, we will consider independent claim 10                       
                as the representative claim for this rejection.                                                                    
                        Appellant argues that the Zinn patent pertains to a central current distribution                           
                arrangement that is unrelated to the fuel injector plug-in connections disclosed by the                            
                Muzslay patent. Appellant asserts that these two references are not from the same field of                         
                endeavor and therefore the combination of the Muzslay patent with the radial seal taught by                        

                                                               -8-
