5), that making the two diode-connected FETs of opposite
conductivity (as recited in independent claims 1, 9, and 15)
would have been obvious "since it is notoriously well-known in
the semiconductor art that NMOS and PMOS field effect
transistors can be substituted for each other without any
unexpected results or change in circuit operation." In fact,
the examiner ignores the explicit disclosures of Yoshida and
Lee that either n-channel or p-channel transistors may be used
for both FETs. Accordingly, we cannot sustain the obviousness
rejections of claims 1, 2, 4, 6, 7, 9, 11, 13 through 18, 23,
and 26 through 30.
CONCLUSION
The decision of the examiner rejecting claims 1, 2, 4, 6,
7, 9, 11, 13 through 18, 23, and 26 through 30 under 35 U.S.C.
§ 103 is reversed.
