page 7, that Hurle is concerned only with the measurement of
the "transfer function" for a conventional Czochralski
process, and the Hurle method utilizes perturbations and a
study of the results of those perturbations to determine the
transfer function. As appellants point out in their brief at
page 7,
"the fact is that the Hurle reference is not
concerned with any automatic control loop and
instead is solely concerned with the determination
of the transfer function of the process which would
later be incorporated into an automatic control
system, although the manner and how the transfer
function is incorporated into this control system is
not specified" (emphasis added).
The arguments made by appellants in their brief are buttressed
by the statements made in the Hurle declaration. Thus, at
paragraph 15.2 of the Hurle declaration, Hurle indicates that
a person of ordinary skill in this art "would perceive that
the techniques in the paper should not be used to grow
crystals but only to determine the transfer function. At
paragraph 15.4, Hurle further indicates in his declaration
that a person of ordinary skill in the art would understand
the perturbations applied by the Hurle publication "were for
measuring how the system responded to such perturbation so
