forward, and a backward driving mode, wherein the driving portion drives the vehicle
backward.
The examiner’s reliance on the disclosure in Brandenfels in column 6, lines 44-
48, for a teaching of this bi-directional drive capability is misplaced. Specifically,
Brandenfels discloses that
[t]he cart can also be used as a dolly, as shown in FIG. 4, for
carrying luggage L, by unlatching the handle from its upright
position and pivoting it forward so that the user can guide
the cart. The user can push or pull the cart or can use the
hand lever 156 to power it.
The disclosure that the user can push or pull the cart, in either a forward or backward
direction, does not constitute a teaching of a driving portion which drives the vehicle
forward in a forward driving mode and backward in a backward driving mode. Rather,
this is a teaching of forward and backward movement in a non-drive mode. The further
disclosure that the user can use the hand lever 156 to power the vehicle or dolly is
silent about selective driving in forward and backward driving modes and, in light of the
disclosed drive arrangement discussed above, would seem to refer to drive in a single
direction only.
