Appeal No. 96-0661
Application 08/189,833
appellant’s invention to utilize a microwave absorption
material having a composition like that taught in Matsubara in
place of the microwave absorption material (e.g., 29) of
Fukuda so as to improve the speed of temperature rise of the
heating element therein (e.g., Matsubara, col. 7, lines 41-45)
and so as to allow such heating element of Fukuda to attain a
temperature level of 1000ºC or above.
Contrary to appellant’s assertion on page 7 of the brief,
we see no reason why it would have been improper to combine
Fukuda and Matsubara in the manner noted supra. In our
opinion, one of ordinary skill in the art would have found
ample motivation in the collective teachings of Matsubara and
Fukuda (as we have noted above) for using a heating element
having a composition such as that taught in Matsubara in
Fukuda. As for appellant’s assertion (brief, page 6) that
Matsubara does not describe the specific claimed combination
of carbon, silicon carbide and alumina powders nor selecting
the proportions of each to provide an operating temperature in
the range of about 30ºC to about 2000ºC, we note column 4,
lines 21-22 and column 6, lines 53-57, of Matsubara wherein it
