          Appeal No. 2001-0966                                                        
          Application No. 08/852,660                                                  

          stem from some teaching, suggestion or implication in the prior art         
          as a whole or knowledge generally available to one having ordinary          
          skill in the art.  Uniroyal Inc. v. Rudkin-Wiley Corp., 837 F.2d            
          1044, 1051, 5 USPQ2d 1434, 1438 (Fed. Cir.), cert. denied, 488 U.S.         
          825 (1988); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc.,         
          776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert.                
          denied, 475 U.S. 1017 (1986); ACS Hosp. Sys., Inc. v.                       
          Montefiore Hosp., 732 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.  Note In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d            
          1443, 1444 (Fed. Cir. 1992).                                                
               With respect to the Examiner’s 35 U.S.C. § 103(a) rejection of         
          independent claims 1, 23, and 29 based on Duxbury, Appellants               
          assert that the Examiner has failed to establish a prima facie case         
          of obviousness since all the claimed limitations are not taught or          
          suggested by the applied Duxbury reference.  At page 11 of the              
          Brief, Appellants assert that the Examiner has erred in
