separable from one another. Further, claim 1 requires
that the two sides’ circuitry include communicators which
are electromechanically coupled by windings for passing
control information by modulating a carrier.
None of the cited references show mechanically
separable primary-side and secondary-side circuit
assemblies with communicators which are
electromagnetically coupled by windings for passing
control information by modulating a carrier.
The examiner states (final rejection, page 4) that Snow
teaches:
a power converter as recited by claims 1, . . .
except for utilizing mechanically separate assemblies.
Gillett et al teaches as old and known in the art at the
time of the invention power converters utilizing
mechanically separable assemblies (120 and 160) for easy
interchangeability of assemblies. It would have been
obvious to one of ordinary skill in the art at the time
of the invention to have modified the power converter of
Snow et al by utilizing mechanically separable assemblies
for ease of interchangeability of assemblies as taught by
Gillett et al.
Additionally, the examiner takes the position (Answer, page 4)
that Snow teaches (col. 1, lines 41-45) that magnetically
coupled feedback via a modulated carrier was old and known in
the art prior to Snow’s invention of an improved feedback
arrangement.
In order to reach the conclusion arrived at by the
examiner, we would first have to modify Snow to replace the
