          Appeal No. 1997-3129                                                        
          Application No. 08/301,743                                                  

          disclosure at page 6, lines 12-14 of the specification which                
          states:                                                                     
                    In the example shown in Fig. 1 the selector 120                   
                    is integrated in chip 100 but the selector 120                    
                    may be a separate circuit component (emphasis                     
                    added).                                                           
               As a final argument, Appellants contend (Brief, page 12)               
          that no teaching or suggestion exists in Sauerwald as to how                
          to implement interconnect test selection circuitry on a chip.               
          This is not surprising, however, since Sauerwald admittedly                 
          has no explicit disclosure of on-chip implementation of                     
          selection circuitry.  It is our view, however, that in view of              
          the availability of at least very-large-scale integration                   
          (VLSI) techniques at the time of filing of Appellants’                      
          application, Appellants’ arguments that the skilled artisan                 
          would not be able to incorporate selection circuitry on a                   
          single semiconductor chip strains credulity.                                
               In view of the above discussion, it is our opinion that                
          the Examiner has established a prima facie case of obviousness              
          which remains unrebuttted by any convincing arguments from                  
          Appellants.  Accordingly, the Examiner’s 35 U.S.C.  103                    
          rejection of independent claims 1, 11, 14, and 17 is                        
          sustained.                                                                  
                                          8
