20. Claims 6, 7, 14 and 15, the only other claims pending in
the application, have been indicated by the examiner to
contain allowable subject matter, but currently stand objected
to until such time that they are rewritten in independent form

Appellants’ invention is directed to a motor and
transmission assembly associated with a vehicle transfer case
that allows the vehicle to be switched between two-wheel and
four-wheel drive modes of operation, and to a method of
operating such an actuator for a vehicle transfer case. More
specifically, the invention involves a transmission for
driving a vehicle transfer case actuator wherein a cushion
(e.g., spring 40 of Fig. 2) is provided for a stop (42) which
prevents movement of the transmission beyond desired ends of
travel. Appellants’ specification (pages 1-2) describes the
state of the art at the time the invention was made. In the
prior art it is indicated that
[i]n theory the worm gear should never approach
the extremes of the stop. As one example, in
the prior art system, only 270E of rotation is
