Application No. 10/248,326
redistribute that heat to the vehicle’s passenger
compartment. Lake, col. 1, l. 8-11, and col. 3, l. 1-17.
To accomplish Lake’s purpose, it is not clear from the
record that persons having ordinary skill in the art would
ever need or desire to periodically change the direction of
coolant flow through the battery pack to improve or
otherwise modify heat transfer from the battery pack to the
HVAC system. The PTO’s initial burden to establish a prima
facie case of unpatentability under 35 U.S.C. § 103 has not
been met.
For the reasons stated, we conclude that the examiner
has not established the unpatentability of appellant’s
claimed invention under 35 U.S.C. § 103. Accordingly, we
reverse the examiner’s final rejections.
