Appeal No. 2000-2060
Application 08/568,209
polysilicon resistor taught by Hawkins in the same layer as the
channel of a MOS transistor, as taught by Tango, in order to
improve performance of the chip and to provide an electrical
connection. See Examiner’s Answer, Page 5, lines 10-15.
Appellant argues that the Examiner has not established a
prima facie case of obviousness with respect to the claims.
Appellant disputes that a portion of layer 80 of Hess functions
as a channel of the transistor. See Appeal Brief, Page 7, lines
25-26. Appellant also asserts that the resistor in Tango is not
a heat transducer but rather is part of a protective circuit that
prevents the gate electrode of the MOS transistor from being
destroyed. See Appeal Brief, Page 6, lines 20-23. Additionally,
Appellant disputes that Tango and Hawkins provide a motivation to
modify the Hess device since Tango relates to safety circuits and
Hawkins relates to reducing warm-up time for a printhead. See
Appeal Brief, Page 6, lines 27-28. As such, Appellant argues
that there is no motivation to combine the teachings of Tango and
Hawkins with Hess to meet the limitations found in the claims.
See Appeal Brief, Page 6, lines 25-27.
