signal, Snow provides an improved regulator that is (col. 1,
line 53) “relatively uncomplicated in design” and (col. 1,
lines 56-57) “in which the number of components and the
manufacturing costs are reduced.” Snow additionally states
(col. 5, lines 13-17) that “the feedback pulse can be used to
directly determine the turn on point and no demodulation is
necessary. This technique maintains the high linearity for
accurate regulation and requires a relative minimum of
circuitry.”
Accordingly, we find that Snow clearly teaches away from
modulating a carrier signal with feedback information. We
therefore conclude that the examiner has not met the burden of
establishing why one having ordinary skill in the art would
have been led to the claimed invention by the express
teachings or suggestions found in the prior art, or by
implications contained in such teachings or suggestions.
We now turn to the second issue of making the first and
second circuit assemblies, each of which includes a
communicator for sending or receiving the control information,
mechanically separable as assemblies from one another.
