          either Smith or Hoffmann in view of Bibby or either Smith or

          (5) Claims 11 through 13 under 35 U.S.C. § 103 as

          in view of Ikoma.                                                           
                                       OPINION                                        
               We have carefully reviewed the claims, specification and               
          applied prior art, including all of the arguments advanced by               
          the examiner and appellants in support of their respective                  
          positions.  This review leads us to conclude that the                       
          examiner’s rejection is not well founded.  Our reasons for                  
          this determination follow:                                                  
               Under 35 U.S.C. § 103, the obviousness of a claimed                    
          subject matter cannot be established by combining the                       
          teachings of cited prior art absent some teaching, suggestion               
          or incentive supporting the combination.  See ACS Hospital
