Appeal No. 95-1987
Application 08/076,475
appellants, it is clear from the well-known heating rate
equation that the dielectric loss factor of the rubber
material being molded and the frequency are interrelated
result effective
variables. Thus, we conclude that one of ordinary skill in
this art would have found the claimed subject matter regarding
the dielectric loss factor values and the frequency range to
have been prima facie obvious. In coming to this conclusion,
we have not ignored the comparative data set forth in Table 2
in the specification at page 9 which indicates that rubber
compounds having conventional compositions could not be
adequately vulcanized at a frequency of 40 MHZ. However, the
specification provides no data regarding comparative examples
at frequencies at the high end of the claimed range, i.e., at
a value of approximately 100 MHZ.
We recognize that appellants' claims also require
the use of a mold "cooperating with a pair of electrode plates
holding said mold therebetween," while Itoh utilizes a mold
which is simply heated by a conventional dielectric heating
