and 6 of Koeppe to “look alike” nor do we find the circuit
layouts of Figures 4 and 8 of Kuwana to “look alike” as required
by the instant claims. The circuit arrangement of Koeppe’s
Figure 5, depicting three parallel circuit branches is clearly
quite different looking than Figure 6 of that reference depicting
a circuit arrangement having four parallel circuit branches.
Similarly, the NAND-gate layout in Figure 8 of Kuwana is quite
clearly different looking than the circuit layout shown in Figure
4 of Kuwana.
The Sawase reference, applied against dependent claims 5 and
14 in combination with Koeppe, does not provide for the
deficiencies noted supra with regard to Koeppe.
Accordingly, since neither Koeppe nor Kuwana discloses or
suggests the multiple different logic circuits having discernible
layouts which look alike, but dopant implant interconnections not
discernible by reverse engineering, as claimed, the examiner’s
rejection of the claims under 35 U.S.C. ' 103 is reversed.
We have reversed both the rejection of the claims under
