determine whether one skilled in the art would have been
motivated to look to Tango and Hawkins in order to teach the
limitations missing from Hess.
Upon a careful review, we fail to find that the Examiner has
provided the evidence to show why one of ordinary skill in the
art would combine the Tango multi-functional layer in the Hess
device. First, while Hawkins provides a teaching of using a
polysilicon resistor in the ink-jet printhead art, there is no
teaching in Hawkins to use a multi-functional or uninterrupted
layer having a first portion that functions as a channel of the
transistor as recited in claims 1 and 18 or portions of an
uninterrupted layer being doped at different levels such that a
first portion functions as the channel of the transistor as
recited in claim 13.
Second when reviewing Tango, we find a discussion of having
the channel region of the transistor and the resistor in the same
layer. See Figure 7, column 3, lines 29-32 and 41-43, and column
4, lines 22-26. Additionally, Tango discusses in column 3, lines
56-59 a doping method to obtain a specific resistance for the
resistor. However, an analysis under 35 U.S.C. § 103 requires a
“reason, suggestion, or motivation found in the prior art whereby
