transistors 2p and 2n, 12p and 12n, etc., we find that McClure
does not make up for the deficiency of Koker. Accordingly,
the rejection of independent claims 21 and 21, and dependent
claims 3-5, 7, and 12-20 under 35 U.S.C. § 103 is reversed.
We turn next to the rejection of independent claim 10.
From our review of Koker and McClure, we are in agreement with
appellants (brief, page 9) that Koker does not disclose the
specific devices that comprise inverter INV1, but presume that
INV1 includes equivalents to E and F . We also agree with 3
appellants (id.) that Koker does not appear to disclose the
lengths of the gates of E and F of INV1, but does disclose the
gate width to be 6 microns, which is the same as the gate
widths of transistors P1pa (A1) and P2pa (A2). In addition,
Koker discloses a ratio of 1:3 for A:B (col. 8, lines 8-17).
McClure, similarly, does not disclose the contents of
inverters 3, 13, etc. We agree with appellants (brief, page
10) that McClure does not appear to disclose values for E and
F. McClure discloses that conventionally, the drive
transistors 2n may have a width/length ratio of three to five
3 For purposes of clarity, we refer to these terms, as well as A, B,
etc., as set forth in appellants' Exhibit 1.
