Appeal No. 96-2661
Application 08/177,975
horizontal linearity error is deemed to be substantially zero,
which meets the claim language limitations. Upon a careful
review of Teuling, we find that Teuling does in fact teach an
S-shape correction circuit means which provides a maximum of
linearity of substantially constant value of less than 5% over
a predetermined range of horizontal
deflection frequencies of 30 kHz to 60 kHz as recited in
Appellants' claim 17. We further note that Teuling teaches
in column 8, lines 47 through 54, that the linearity error and
the S-distortion for all the frequencies between f and fmin max
can substantially be eliminated. Furthermore, we agree that
Appellants have admitted on pages 21 and 22 of the
specification that the highest horizontal deflection frequency
is conven- tionally 60 kHz and the lowest horizontal
deflection frequency is conventionally 30 kHz. We further
find that it would have been obvious to those skilled in the
art to recognize that Teuling, when speaking of the f and
min
the f , was referring to the conventional 30 kHz and 60 kHz
max
as admitted by Appellants in the Appellants' specification.
