              Appeal No. 2001-0557                                                                  Page 3               
              Application 09/376,548                                                                                     


                     Rather than reiterate the conflicting viewpoints advanced by the examiner and the                   
              appellants regarding the above-noted rejections, we make reference to the Answer (Paper                    
              No. 9) for the examiner's complete reasoning in support of the rejections, and to the Brief                
              (Paper No. 8) and Reply Brief (Paper No. 10) for the appellants’ arguments thereagainst.                   
                                                       OPINION                                                           
                     In reaching our decision in this appeal, we have given careful consideration to the                 
              appellants’ specification and claims, to the applied prior art references, and to the                      
              respective positions articulated by the appellants and the examiner.  As a consequence of                  
              our review, we make the determinations which follow.                                                       
                     All of the standing rejections are under 35 U.S.C. § 103(a).  A prima facie case                    
              of obviousness is established when the teachings of the prior art itself would appear to                   
              have suggested the claimed subject matter to one of ordinary skill in the art (see In re Bell,             
              991 F.2d 781, 782, 26 USPQ2d 1529, 1531 (Fed. Cir. 1993)).  This is not to say,                            
              however, that the claimed invention must expressly be suggested in any one or all of the                   
              references, rather, the test for obviousness is what the combined teachings of the                         
              references would have suggested to one of ordinary skill in the art (see, for example,                     
              Cable Elec. Prods. v. Genmark, 770 F.2d 1015, 1025, 226 USPQ 881, 886 (Fed. Cir.                           
              1985)), considering that a conclusion of obviousness may be made from common                               
              knowledge and common sense of the person of ordinary skill in the art without any specific                 
              hint or suggestion in a particular reference (see In re Bozek, 416 F.2d 1385, 1390, 163
