least the conventional stripping of woven acrylic insulators,
thereby reducing manufacture time." (Answer, page 4).
We disagree. Armbruster merely shows another manner in
which the stator wires can be insulated from the heat sink, in
this case by passing them through in an insulated sheath, rather
than coating them with insulation, as is shown in the appellants'
Figure 2. Therefore, in our view, Armbruster essentially adds
nothing new to the prior art system. Lakin discloses no stator
wires and no ventilation windows through which they can pass.
The problem in Lakin is to insulate the windings of the stator
core, and not the stator connecting wires, from the laminated
core. Granted, this is accomplished by covering a portion of the
core with an insulating material. However, from our perspective,
the only motivation for applying this teaching to the ventilating
windows of an alternator heat sink in the manner proposed by the
examiner is found in the hindsight provided by one who first
viewed the appellants' disclosure. This, of course, is
impermissible. See In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d
1780, 1784 (Fed. Cir. 1992).
The rejection is not sustained.
The decision of the examiner is reversed.
