Appeal No. 96-3304
Application 08/279,565
find no motivation in the applied prior art to modify the
tamper indicating mechanism disclosed in Becker so that the
display unit displays changeable readable indicia
representative of energy consumed. Indeed, there would be no
reason to make this change as the apparatus disclosed in
Becker includes a metering mechanism 5 for measuring
electrical power consumption (see column 3, lines 54-65). As
such, we will not sustain this rejection as it is directed to
claim 14 and dependent claims 15-22.
Turning next to the examiner’s rejection of claims 10 and
23 under 35 U.S.C. § 103 as being unpatentable over Becker and
Wakatsuki and further in view of Munday, the examiner cites
Munday for disclosing a liquid crystal diode for display
means. According to the examiner, it would have been
obvious to one of ordinary skill in the art at the time of the
invention to have provided the meter of Becker as modified
with Wakatsuki with a display means including a liquid crystal
diode in order to better place readable information in
readable form. Even if we were to agree with the examiner’s
proposed modification of Becker in view of Munday, the
tertiary reference does not remedy the deficiencies noted
