                Appeal No. 2005-1581                                                                                      7                 
                Application No. 09/681,692                                                                                                  

                why the results achieved in the specification would have been unexpected by one of                                          
                ordinary skill in the art, see In re Freeman, 474 F.2d 1318, 1324, 177 USPQ 139, 143                                        
                (CCPA 1973); In re Klosak, 455 F.2d 1077, 1080, 173 USPQ 14, 16 (CCPA 1972).                                                
                        Based on our consideration of the totality of the record before us, having                                          
                evaluated the prima facie case of obviousness in view of Appellants' arguments and                                          
                evidence, we conclude that the subject matter of claims 1-36 would have been obvious                                        
                to a person of ordinary skill in the art from the teachings of the McGrew and Yatka                                         
                references.  See In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.                                        
                1992).                                                                                                                      
                                                           CONCLUSION                                                                       
                        For the foregoing reasons and those set forth in the Answer, based on the totality                                  
                of the record, we determine that the preponderance of evidence weighs in                                                    
                favor of obviousness, giving due weight to Appellants= arguments and evidence.                                              
                Accordingly, the Examiner's rejection under 35 U.S.C. ' 103 is affirmed.
