Appeal No. 95-3194
Application 08/020,232
interconnected determines the type of control only, and does not
affect the teachings of generating electromagnetic fields by
applying current through a coil surrounding a pole piece of the
stator. The person skilled in the art of variable reluctance
motors would be expected to be familiar with other types of
motors which also use magnetic stators and rotors to cause
movement of the rotor with respect to the stator.
Appellants argue that if the series connected strapping
or foil wire of Finegold were to be placed into the motors of
Obradovic, Konecny or the admitted prior art, such motors would
not operate as variable reluctance motors any longer [brief, page
7]. The problem with this argument is that it presumes that the
artisan has no knowledge whatsoever. The artisan would have
known that the coils of a variable reluctance motor must be
unconnected as taught by each of Obradovic, Konecny and the
admitted prior art. Therefore, the artisan would not retain the
series connection of Finegold if the coils were intended for use
in a variable reluctance motor.
The question as we see it is whether the artisan would
have found it obvious to replace each of the coils of the
variable reluctance motors with an individual coil made of
strapping or foil wire as taught by Finegold. Appellants argue
