Appeal No. 2001-2441
Application No. 09/067,923
Tokunaga does not address whether a thermal magnetic transfer
layer containing such an amount of calcium carbonate pigment and
containing the ferromagnetic powders which are pigments would be
receptive to thermal transfer ink. However, Tokunaga would have
fairly suggested to one of ordinary skill in the art, for the
purpose of providing a thermal magnetic transfer ribbon, a
thermal transfer layer which has amounts of white pigment and
total pigment within the appellants’ 5-80 wt% range and, as
discussed above, otherwise falls within the scope of the
appellants’ claim 14 and which, therefore, has the properties of
the appellants’ claimed thermal transfer ribbon.
Hence, we conclude that the thermal transfer ribbon recited
in the appellants claim 14 would have been obvious to one of
ordinary skill in the art over Tokunaga.
Claim 17
Claim 17, which depends from claim 14, recites that the
pigment comprises 40-50 wt% of the total dry ingredients within
the thermal transfer material.
The examiner points out that the upper limit of Tokunaga’s
range of extender pigment, which can be white, is 30 wt%, and
