circuits with alternately wound coils as taught by Nishio. In
addition, the examiner expands on the motivation for combining
the teachings of Naoki and Nishio stating (answer, page 7) that:
As the applicant admitted, Naoki et al.
purpose is to reduce the circulating current in a
parallel circuit. Although Naoki et al. do not
use the alternately wound coils to further
decrease the circulating current, Nishio et al.
teach to wind the winding alternately in order to
reduce the cogging torque, which is a well known
problem in the art of motor and generator. In
addition, Nishio et al. even disclose the problem
of cogging torque with windings wound around the
stator poles in the same direction in Figures 15-17
and columns 1-3. As a result, one having ordinary
skill in the art would recognize that there is a
problem with cogging torque in the machine of Naoki
et al. Therefore, using the alternate winding of
Nishio would not destroy the purpose of the basic
Naoki reference. Instead, it can improve the
performance of the motor by reducing cogging torque
as disclosed in column 3 of Nishio reference while
maintaining low circulating current as shown in
paragraph 0017 of Naoki et al.
Appellants admit (brief, page 3) that Naoki discloses a
plurality of series circuits in parallel, and that Naoki's
purpose is the same as appellants. However, appellants assert
(id.) that they have gone a step further in solving the problem
(of preventing the generation of a circulating current in the
parallel circuit due to a phase difference of an electromotive
