Appeal No. 96-1301
Application 08/175,078
Claim 4 of the Hawsey patent further recites that: 1) the
first set of magnets are oriented to provide alternating
polarities; 2) the second set of magnets are oriented to
provide alternating polarities; and 3) the polarities of the
second set of magnets are opposite the polarities of the first
set of magnets across the central layer of the rotor.
The Hawsey claim language indicates that the polar
orientation of the magnets are co-directional, because the
polarities of the magnets on the first layer are opposite the
polarities of the corresponding magnets on the second layer.
Opposite polarities on opposing faces result in magnetic
fields that are co-directional. See applicants’ Figure 3a.
Therefore, Hawsey meets the limitation that “the polar
orientation of said magnet pieces of said pair of permanent
magnets is co-directional.”
Appellants draw attention to the prior art Fig. 3b of the
instant application, which is the appellants’ interpretation
of the Hawsey invention. Appellants assert that the “co-
directionality of opposing magnetic pieces in a rotor
according to the present invention is in sharp contrast with
the Hawsey configuration wherein corresponding magnets on
