Appeal No. 96-3728
Application No. 08/132,078
These are all of the claims remaining in the application.
The subject matter on appeal relates to a tamper
resistant magnetic stripe for encoding by magnetic particle
rotation and to a method for encoding a magnetic stripe. This
appealed subject matter is adequately illustrated by
independent claims 2 and 22 which read as follows:2
2. A tamper resistant magnetic stripe for encoding by
magnetic particle rotation comprising:
a radiation crosslinkable material which is solid at
ambient temperature and which before cross-linking has a
viscosity of 1,200 poise or less at 40EC; and
magnetized particles of a magnetic composition in
suspended distribution throughout said crosslinkable material,
said particles have a coercivity of at least 5 kOe;
said particles in selected regions of said material being
substantially all similarly aligned with respect to their
magnetic polarity and the material of said regions is cross-
linked, and in the remaining regions of said material the
particles therein being substantially all similarly aligned
with respect to their magnetic polarity in a direction which
is 180E opposed to said particles in said selected cross-
linked regions;
wherein said selected and remaining regions alternate
along said stripe to define a magnetic code.
2We observe that claims 22 and 23 have been inaccurately
reproduced in the appendix of the appellants’ brief. Suffice
it to say that our decision on this appeal is based upon the
actual language of the appealed claims rather than the
inaccurate language of the appellants’ claim reproductions.
