Appeal 2007-0037
Application 10/032,056
metal in an active matrix LCD device to reduce the resistance of the lines"
(Final Rejection 4).
DISCUSSION
Appellant does not separately argue the patentability of the dependent
claims. Accordingly, the claims stand or fall together with the rejection of
independent claim 1. See 37 C.F.R. § 41.37(c)(1)(vii).
Appellant does not contest that the only difference between the
subject matter of claim 1 and the APA is that the APA does not disclose "a
metal layer formed on an entire surface of each of the data lines."
The issue is whether Kakuda provides teaching, suggestion, or
motivation for one of ordinary skill in the art to modify the APA to provide
"a metal layer formed on an entire surface of each of the data lines."
Kakuda teaches that "in an active matrix LCD (liquid crystal display),
it is desirable, for the purpose of reducing the resistance of matrix lines, to
employ a laminated structure in which an aluminum film overlies the ITO
film forming the transparent electrode, but direct lamination of the ITO and
aluminum (Al) films poses a problem as the ITO is corroded by preferential
dissolution resulting from galvanic action between the dissimilar metals"
(emphasis added) (col. 7, ll. 51-59). Thus, Kakuda teaches that it is
desirable to provide a metal layer over the entire surface of the data lines to
reduce the resistance which is an express teaching/suggestion/motivation for
one of ordinary skill in the art to modify the APA to provide such a metal
layer. Moreover, this is the same reason that Appellant uses the metal layer
