Application No. 08/532,886
Appellant argues that the second package judges the validity of the data in the backup
memory depending on the state stored in the state memory which is based upon whether
the backup memory has been disconnected. (See brief at page 5.) We agree with
appellant that the claimed invention detects the detachment and sets an indicator that the
memory has been detached and that the data therein should not be trusted and is deemed
not valid. (See brief at page 6.)
Appellant argues that Matsushita does not teach or suggest any detachable feature, but
Matsushita does detect whether there is a lack of adequate power to the memory and
judges the validity of the data based upon the low power condition. (See brief at page 6.)
We agree with appellant that Matsushita does not recognize the disconnection and setting
of a state memory based upon a disconnection signal.
Appellant argues that Saitoh teaches the detection of a disconnection of the memory
and automatic switching of the power from one power source to another power source.
(See brief at page 6.) Appellant argues that in the combination of the two teachings, the
only basis for judging validity of the data would have been the whether there was a lack of
adequate power constantly supplied to the memory. (See brief at page 7.) We agree with
appellant. From our review of Matsushita and Saitoh, we find no motivation to have a
signal indicating the disconnection and storage of this state in a state memory. Rather, we
