calibration” taught by the reference. Columns 5 and 6 of Mussler are pointed out “for
examples of various calibration values.”
Mussler does not explicitly disclose any of the calibration values (calib(0) through
calib(9)) changing after initial calibration. “[S]ubsequent application routines” (see column
6, lines 28-31) may use the coordinate translation matrix to generate normalized X and Y
(X and Y ) coordinates. The “actual display coordinates” (X and Y ) can be generatedN N gd gd
using the normalized X and Y coordinates (see column 5, lines 39-47). Presumably,
application programs could provide new or different values of calib(6) through calib(9) for
generating the actual display coordinates, since these calibration values, as identified in
formulas 14 through 17, are expressed in graphic display coordinates. An application
program using different windows, or using a different screen resolution, might generate
actual graphic display coordinates using its own offsets and scale factors.
However, even if these presumptions concerning the implicit teachings of the
reference are correct, Mussler refers only to “subsequent application routines” using the
coordinate translation matrix and generating normalized X and Y coordinates. Claim 1, on
the other hand, requires that the touch processor includes means for automatically
adjusting calibration data stored in the touch memory in response to correction data
“received from [the] display processor.” The examiner’s position, as expressed in the
paragraph bridging pages 8 and 9 of the Answer, is that new coordinates (correction data)
are necessarily communicated to the controllers for the touch control screen (TCS) and
