Appeal No. 2006-1726
Application No. 09/725,849
American Hoist & Derrick Co., 730 F.2d 1452, 1458, 221 USPQ 481,
485 (Fed. Cir. 1984).
With respect to the Takahashi reference, Appellants argue at
page 7 of the Appeal Brief that Takahashi does not disclose that
“the first signal is applied during the beginning of the frame
and the second signal is applied during the ending of the frame.”
To determine whether claim 1 is anticipated, we must first
determine the scope of the claim. We note that claim 1 reads in
part as follows:
“applying a first signal to the liquid crystal pixel
cells through said data lines for charging thereof
during a beginning of a frame; and applying a second
signal different from said first signal to the liquid
crystal pixel cells through said data lines for
discharging thereof during an ending frame.”
At page 7, line 28 through page 8, line 22, Appellants’
specification states:
As shown in Fig. 7, the liquid crystal pixel cells are
charged by a video data signal when the gate pulse GP
is applied to the TFT and a channel of the TFT is
formed. After the gate pulse is turned off, the liquid
crystal pixel cells maintain the charged video data
signal. When the gate pulse GP is again applied to the
TFTs during the duration of the frame, e.g., at the
mid-point of the frame, the TFTs are driven and the
liquid crystal pixel cells perform a discharge due to
an off-voltage applied on the data lines. After the
