Appeal No. 1997-3643
Application No. 08/484,047
reverse the rejection.
As discussed in detail below, the prior art fails to teach or suggest appellants’ claimed printing
inks, processes for making printing inks and processes for printing on a substrate. As recognized by the
examiner, appellants’ independent claims require the employment of an alkyd resin prepared from an
unsaturated fatty acid having an iodine number from 120 to 190 and that the alkyd resin has a hydroxyl
number from 40 to 260 and an acid number of less than 11. Yet, the prior art relied upon by the
examiner fails to teach or suggest preparing such an alkyd resin and combining it with a phenolic resin-
modified rosin to form a binder for a printing ink. As the prior art fails to teach or suggest such an
alkyd resin for a printing ink binder, the examiner has failed to establish that the references form a
prima facie case of obviousness for the subject matter defined by the appealed claims.
The Prior Art
Savageau, U.S. Patent No. 3,772,171
Savageau relates to a novel quick setting ink containing photosensitizers. The quick-setting inks
normally comprises a colorant and a vehicle containing an oil or oil-derived alkyd, a solvent and a resin.
(Savageau, col. 1, lines 22-24). The oil or alkyd may be present in the composition in an amount
ranging from 10 to 40 percent by weight and the resin may be present in an amount ranging from 10 to
60 percent by weight. (Savageau, col. 2, lines 20-28). The resins which may be used in quick setting
