At page 5 of the answer, the examiner states that,
Therefore, it is submitted that one having ordinary
skill in the art would be motivated by the disclosure of
Wayman et al (‘182), noted supra, to add even more
thermally conductive materials to the belt-shaped fuser
member of Wayman et al (‘182) if they (sic) wanted to
increase the thermal conductivity that is already inherent
in said disclosed belt-shaped fuser member noted supra.
The above quotation of the examiner does not state a
motivation or suggestion to add thermally conductive material to
the layer 64 of fuser 52 of Wayman. There is no explanation in
the examiner’s statement as to why one of ordinary skill in the
art would have wanted to increase the thermal conductivity of
Wayman’s fuser. For example, there is no evidence that Wayman’s
printing apparatus suffers from overheating, such that the
artisan would have added more thermally conductive material to
the fuser to dissipate heat therefrom at a faster rate.
However, even if there were some given motivation or
suggestion to add thermally conductive material to the fuser 52,
the added thermally conductive materials would most likely have
been added to layer 66, which Wayman discloses as containing
thermally conductive materials, not to layer 64 which does not
contain such material.
Lastly, it is evident from Wayman’s disclosure (column 8,
lines 8-17) with respect to Figure 3 that the amount of heat
generated by the printing apparatus is directly dependent on the
