from the battery cells. Representative Claim 1 is
reproduced below:
1. A battery system for an automotive vehicle,
comprising:
a battery case;
a plurality of battery cells housed within said
case;
a plurality of heat transfer passages extending
about said battery cells;
a supply of heat transfer working fluid;
at least one working fluid driver for circulating
said heat transfer working fluid from said supply and
through said heat transfer coolant passages; and
a controller for operating said at least one
working fluid driver so as to periodically reverse the
direction of the flow of heat transfer working fluid
through said heat transfer passages.
The examiner relies upon teachings of the following
prior art references in support of the final rejection:
Lake et al. (Lake), U.S. Patent 6,138,466,
issued Oct. 31, 2000; and
Kothmann et al. (Kothmann), U.S. Patent 4,582,765,
issued Apr. 15, 1986.
Claims 1-20 stand finally rejected as unpatentable
under 35 U.S.C. § 103 for obviousness in view of the
combined teachings of Lake and Kothmann. We reverse.
2. Discussion
Claims 1-20 stand rejected under 35 U.S.C. § 103
because subject matter thereof would have been obvious to a
person having ordinary skill in the pertinent art in view of
