          Appeal No. 2002-1578                                                        
          Application No. 08/814,928                                                  


          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 Appellants to come             
          forward with evidence and/or arguments which persuasively rebut the         
          Examiner’s prima facie case of obviousness.  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 [see 37 CFR § 1.192(a)].                 
               Appellants’ arguments in response to the obviousness rejection         
          based on the combination of Leak and Terada assert that the                 
          Examiner has failed to establish a prima facie case of obviousness          
          since all of the claimed limitations are not taught or suggested by         
          the applied prior art references.  After careful review of the              
          applied Leak and Terada references in light of the arguments of             
          record, we find Appellants’ assertions to be unpersuasive.  In our          
          view, Appellants’ arguments unpersuasively focus on the individual          
          differences between the limitations of representative claim 31 and          
          each of the applied references.  It is apparent, however, from the          
          Examiner’s line of reasoning in the Answer, that the basis for the          
          obviousness rejection is the combination of Leak and Terada.  One           
          cannot show nonobviousness by attacking references individually             

                                          6
