to Marks' automated ledger account system. Marks discloses
(col. 2, lines 4-11) that:
[C]omputer systems introduce the possibility
of computer records being altered or erased
or deleted without any indication of a separate,
correction entry. This has created a number of
serious accounting, auditing, and reporting problems,
such as detection of unauthorized changes to the data
recorded in the computer records, unauthorized deletion
of valid records, and unauthorized insertion of
accounting records.
Marks further discloses (col. 16, lines 41-46) that “the system
provides complete traceability so that unauthorized changes to
the accounting records stored in the system’s data files are
readily detectable by automated processes. Thus, the system
provides a higher level of security than known computer
implemented accounting systems.” Because Marks is directed to
providing heightened security to accounting records in order to
prevent unauthorized changes to the system's data files, we find
no teaching or suggestion, and no convincing line of reasoning
has been advanced by the examiner, that would have taught or
suggested to an artisan the modifications proposed by the
examiner. In any event, even if there was a suggestion in the
prior art to combine teachings of Bigus and Marks, claim 3 would
still not be met because there is no teaching or suggestion
suggestion of which functions in Marks should become core
