          Appeal No. 1998-1408                                      Page 17           
          Application No. 08/569,529                                                  


          35 U.S.C. § 103(a).  Next, we address the obviousness of                    
          claims 2-4.                                                                 


                                     Claims 2-4                                       
               The appellants argue, “Claim 2 ... further recites that                
          elongated conductors are printed on both sides of the flexible              
          dielectric sheet.  In contrast, Dirks only teaches conductors               
          embedded within the molded bridges 23 and 24.”  (Appeal Br. at              
          5.)  They add, “Sato likewise teaches a single set of                       
          conductors within the belt.  Layton et al. teach a flex                     
          circuit but conductors are printed only on one side of the                  
          dielectric sheet.”  (Id. at 6.)  The examiner replies,                      
          “Printed circuit conductors can be applied to one or both                   
          sides of printed circuit board or sheet ....”  (Examiner’s                  
          Answer at 5.)                                                               


               Claims 2-4 each specify in pertinent part the following                
          limitations: “said conductors are printed on one side of said               
          sheet and ... other elongated conductors printed on the other               
          side of said sheet ....”  In other words, the limitations
