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.
