Appeal 2007-0037
Application 10/032,056
We generally agree with Appellant that the Examiner's statement of
motivation is not persuasive. Kakuda is concerned with the benefits of the
light blocking layer to shield the thin film transistor and a storage
capacitance electrode. Adding a metal layer to the data line has nothing to
do with a light blocking function (which the Examiner appears to concede at
Answer 4, ll. 6-7). Nor does adding a metal layer having anything to do
with simplifying the manufacturing process: the manufacturing process is
simplified by making the ITO data line 11a and the ITO pixel electrode 11 at
the same time, which has nothing to do with the metal layer 11b.
Nevertheless, the Examiner pointed to column 7, lines 44-67, in the
Final Rejection and states in the Examiner's Answer that "Kakuda then goes
on to disclose (col. 7, lines 51-55) 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 . . .'" (Answer 6-7)
and that "Kakuda specifically teaches that the LCD device has a data line11a
with a metal layer (molybdenum-base alloy) 11b formed on the entire
surface (col. 4, lines 45-49)" (Answer 7). Thus, the Examiner has pointed to
the relevant motivation in Kakuda to modify the APA.
Appellant recognizes the Examiner's reliance on column 7,
lines 44-67, of Kakuda for the known practice of forming laminated matrix
lines of ITO and metal in an active matrix LCD device to reduce the
resistance of lines, but argues that it "is completely taken out of context with
