have found it obvious to interweave the conduits of the two
heat exchangers of the modified O'Neal structure in view of the
teachings of Wasielewski. We do not agree.
Wasielewski discloses a heat transfer apparatus which, in
pertinent part, has a first heat exchanger comprising a
plurality of spaced, parallel horizontally oriented conduit 6
and a second heat exchanger comprising a plurality of spaced,
parallel vertically oriented conduits 7. These are each
separate conduits, which span the distance between,
respectively, vertical
walls 8 and horizontal walls 9. They do not form a serpentine
configuration, as required by claim 1, nor are they connected
together so that they form a continuous conduit, as required
by claims 11 and 16. While the rows of vertical conduits are
interposed between the rows of horizontal conduits, it is our
view that this does not constitute interweaving, as defined
above and required by the claims. Moreover, even if one were
to accept the examiner's position that Wasielewski discloses
an interweaved arrangement, the examiner has not pointed out,
and we fail to perceive, any teaching, suggestion or incentive
which would have led one of ordinary skill in the art to
modify the Oogushi serpentine conduits, as transposed into the
