Appeal No. 1998-2601
Application 08/809,052
examiner asserts that it would have been obvious to modify the
Bahn motor to have alternately magnetized stator poles as
taught by Konecny to minimize flux leakage and improve torque
characteristics of the motor [answer, pages 3-4]. With
respect to dependent claims 2-4, the examiner finds the
limitations of these claims to be the obvious result of
optimizing system parameters.
With respect to claim 1, appellant notes that the
claimed invention recites that electric current is applied to
the stator coils in an overlapping manner with alternate
magnetic polarities so as to produce an effective leakage flux
between adjacent magnetic poles. Appellant argues that there
is no such overlap of current applied in Bahn so that Bahn
does not produce any such effective leakage flux. Appellant
argues that Konecny also does not teach the production of an
effective leakage flux so that Konecny does not make up for
the deficiencies of Bahn [brief, pages 6-8].
The examiner responds that the combination of Bahn
with Konecny would “inherently” result in overlapping coil
currents which would produce a leakage flux as claimed
[answer, page 8]. Appellant responds that neither Bahn nor
