Appeal No. 2000-0185
Application 08/847,111
form.
Appellants' invention relates 1) to a seal (12), seen
best in Figure 2 of the application, wherein first (21) and
second (22) sections of the seal have different hardness, more
particularly, where the second section has a hardness that is
less than the hardness of the first section (see claim 17),
and 2) to a heat exchanger assembly (Figs. 1-2) that uses the
above seal in a peripheral space between the housing (10) and
the heat exchanger core (11) (see claim 1). An adequate
understanding of the claimed subject matter can be had from a
reading of illustrative claims 1 and 17, the two independent
claims on appeal. A copy of those claims, as they appear in
the Appendix to appellants' brief, is attached to this
decision.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
