          Appeal No. 1997-0243                                                        
          Application 08/168,976                                                      

          [supplemental reply brief, pages 3 to 6] that Haderle's method              
          of checking the integrity of data is different from the                     
          claimed method.                                                             
               We have reviewed the Examiner’s citations of col. 12 and               
          col. 7.  Col. 12, lines 19 to 24 of Haderle state that “[t]he               
          deferred method extracts foreign key values, then sorts them                
          to allow referential integrity checking ....” (Emphasis                     
          added).  Col. 7, lines 23 to 27 of Haderle further state that               
          “the SORT phase 26 sorts the key data set 50 ... loaded in                  
          Data Load phase 24, into a sorted key data [set] 68 set (sic)               
          which is optimal for index updating and efficient checking of               
          referential constraints" (emphasis added).                                  
               We opine that Haderle is a multi-phase method in contrast              
          to the claimed single-phase process.  The Examiner’s assertion              
          that it is a mere design choice to come up with the claimed                 
          steps of the claimed single-phase method of data-integrity                  
          checking using Haderle’s quoted teachings is not tenable.                   
          Therefore, we do not sustain the Examiner’s obviousness                     
          rejection of claim 1 over Haderle.
