          Appeal No. 1998-1800                                                        
          Application No. 08/430,453                                                  


          826, 159 USPQ 342, 344 (CCPA 1968); W.L. Gore & Assocs. v.                  
          Garlock, Inc., 721 F.2d 1540, 1550, 220 USPQ 303, 311 (Fed.                 
          Cir.                                                                        
          1983), cert. denied, 469 U.S. 851 (1984).                                   
               In order for us to sustain the Examiner’s position we                  
          would, at the very least, have to completely divorce Olson’s                
          description of the split-mode embodiment illustrated in                     
          Figures 4 and 5 from the remainder of the Olson disclosure.                 
          Such an approach, however, would be directly contrary to the                
          express disclosure of Olson.  Olson describes the Figure 4                  
          split-mode embodiment as a modification of the Figure 1                     
          circuit and, in describing the                                              
          address decode circuit 43a, discloses that it is identical to               
          the address decode circuit 43 of Figure 1 except for an                     
          additional output line to a split-mode control register 97.                 
          In our view, the only conclusion that can be drawn from this                
          portion of Olson is that the write operation in the split-mode              
          embodiment, which is never discussed by Olson, must be                      
          identical to the write operation specifically described in                  
          Figure 3 in relation to the operation of the Figure 1                       
          circuitry.  This write operation, illustrated in the right                  
                                         10
