          Appeal No. 2006-1225                                                        
          Application No. 10/244,825                                                  

               Rather than reiterate the opposing arguments, reference is             
          made to the brief (filed April 18, 2005), the reply brief (filed            
          July 20, 2005) and answer (mailed May 18, 2005)for the respective           
          positions of Appellants and the Examiner.                                   
                                       OPINION                                        
               Starting with claim 1, Appellants argue that Ogata merely              
          teaches (page 1) a server duplex system incorporating a working             
          server and a standby server (brief, page 7).  Appellants point to           
          paragraph 18 of Ogata and argue that the reference describes two            
          servers 1A and 1B which can alternately access the auxiliary                
          storage unit whereas the claim requires grouping a switch and the           
          storage device such that data only passes to the storage device             
          from the switch (brief, page 8).  Appellants also argue that                
          Ogata describes a duplex system (paragraphs 0021-0024) which does           
          not restrict access to the storage device from a server included            
          in the storage system such that data only passes to the storage             
          device from the switch (brief, pages 9-10).                                 
               In response, the Examiner argues by stating that the claim             
          is not limited to only one switch and data can pass to the                  
          storage device from one or more switches (answer, page 5).  The             
          Examiner further reasons that even if the claim is limited to a             
          single switching element, the claim is met since only one of the            
                                          3
