Appeal No. 95-4678
Application 08/097,572
capacitive or inductive reactor. An alternative source
of current is provided by the battery 6, selection of
the transformer or battery circuit being effected by a
two-way switch 15 actuated by the armature 16 of relay
10 [page 1, line 77 through page 2, line 27].
According to the examiner, the Duncan reference does not
meet the limitations in independent claims 1 and 20 noted above
because Duncan “does not disclose making the power pack housing
in the form of an enclosure or the use of attachment means to
secure the sign to a support structure” (main answer, page 4).
Shine discloses an illuminated exit sign assembly comprising
a main housing 20, a self-contained auxiliary power supply 22
removably mountable to the top of the housing, and means on the
housing for attaching it to an electrical junction box (see
column 4, line 64 through column 5, line 24).
In explaining the appealed rejection, the examiner states
that
[i]n view of the teachings of Shine it would have been
obvious to one in the art to modify [Duncan] by placing
an attachment means on the exit sign since this would
allow the sign to be attached to a support structure.
In view of the teachings of Shine it would have been
obvious to one in the art to modify [Duncan] by making
the power pack housing in the form of an enclosure
since this would allow the power pack housing to be
easily attached and removed from the sign housing to
allow easy access to the components inside the power
pack housing [main answer, page 4].
