Application No. 08/019,666
sufficient motivation for modifying Reiser. Katogi discloses
a liquid crystal instrument panel for a vehicle with a
fluorescent backlight. In column 7 Katogi discusses using a
DC/AC converter to supply AC voltage to the fluorescent lamp.
Nowhere, however, does Katogi suggest a need for a DC/AC
converter for an LED display such as the one disclosed by
Reiser. Although we agree with the examiner that such
converters are well-known, there must be a reason in the
references as to why one would be motivated to modify the
display of Reiser to include a DC/AC converter. As we find no
such motivation, we cannot sustain the rejection.
Under the provisions of 37 CFR § 1.196(b), we enter the
following new ground of rejection against appellants' claims
1, 2, and 5:
Claims 1, 2, and 5 are rejected under 35 U.S.C. § 103 as
being unpatentable over Reiser in view of Fahs.
Reiser discloses all of the claimed invention except for
a DC/AC converter, as explained in detail above. Fahs relates
to a vehicle mounted LED display that is controlled by a
computer processor from inside the vehicle and powered by the
car battery. (See column 1, line 64-column 2, line 5 and
