on Lindblad’s teaching of using a hydroxy containing charge
transport molecule in the overcoat layer. See pages 8 and 11
of the answer. We disagree. The examiner has not
adequately explained how Lindblad taken with Takei suggests
such a modification. While Lindblad does suggest that the
charge transport molecules may contain hydroxy groups, the
examiner has, in essence, acknowledged that Lindblad does not
teach the use of the herein claimed hydroxy triphenyl methane
as a charge transport material (CTM) for use in the overcoat
layer of Lindblad. See answer, page 7. The mere fact that
the general formula for the arylalkane compound additive of
Takei may be inclusive of a hydroxy triphenyl methane does not
explain why one of ordinary skill in the art would be led to
select such a hydroxy triphenyl methane for use as a CTM in
the
overcoat layer of Lindblad. This is especially so given that
the examiner has not explained why one of ordinary skill in
the art would have selected one of the many types of
arylalkane compounds disclosed in Takei as an alternative CTM
for use in Lindblad since Takei teaches that a CTM should be
selected from among
