`
`PRESUMPTION THAT DIFFERENT CLAIMS HAVE DIFFERENT SCOPES
`
`“Beyond the independent / dependent claim scenario, this court has
`characterized claim differentiation more generally, i.e., as the
`‘presumption that each claim in a patent has a different scope.’”
`
`Curtiss-Wright Flow Control Corp. v. Velan, Inc., 438 F.3d 1374, 1380
`(Fed. Cir. 2006)
`
`“The difference in meaning and scope between claims is presumed to be
`significant ‘to the extent that the absence of such difference in meaning
`and scope would make a claim superfluous.’”
`
`Versa Corp. v. Ag-Bag Int'l Ltd., 392 F.3d 1325, 1330 (Fed. Cir. 2004)

`

`
`THE SPECIFICATION DESCRIBES CONTROLLING THE OPERATION
`OF THE PIXEL WITHOUT REFERENCING OVERDRIVING
`
`“Generally when driving an LCD, a driving circuit receives a plurality
`of frame data and then generates corresponding data impulses,
`scan voltages, and timing singles, according to the frame data, in
`order to control pixel operation of the LCD.”
`
`Ex. 1001, ’843 Patent at 1:27-31.
`
`“The switching device 38 is connected to the corresponding scan
`line 32 and the corresponding data line 34, and the source driver
`18 and the gate driver 20 control the operation of each pixel 36 via
`the scan line 32 and the data line 34.”

`
`15
`
`

`
`THIS INTERPRETATION IS ALSO BELIED BY FIG. 2 OF THE ’843 PATENT
`
`“Two curves C1, C2 are measured when the driving circuit changes the transmission rate
`from T1 to T2 beginning at frame period N. The curve C1 shows the transmission rate of
`a pixel not overdriven corresponding to the frames, and curve C2 shows the
`transmission rate of the pixel overdriven corresponding to the frame.”
