Appeal No. 95-1859
Application 08/055,100
oil-containing ink to print on the three-layer label laminate
called for by applicant's claim 1.
Independent of the examination conducted by the examiner,
we have found that the film used to make applicant's print-
receiving layer is old. See Young, U.S. Patent 4,861,644.
Young tells us that letterpress printing may be used to
accomplish printing on a print-receiving layer (col. 11, lines
33-39). Kirk-Othmer further tells us that letterpress
newsprint inks are based mainly on mineral oil (page 616,
fourth paragraph). But like the product brochure, Young does
not describe the three-layer label called for by the process
of claim 1. We have also found that three-layer labels are
old. See Beck, U.S. Patent 3,660,203 (1972) (Fig. 2 and col.
1, lines 61-66). However, the print-receiving layer described
by Beck is not a TESLINŽ film layer. More important is the
fact that the brochure, Young, Beck and Kirk-Othmer do not
describe printing with a mineral oil such that the ink does
not come into contact with the adhesive layer, as required by
claim 1. On this record, we conclude that applicant has
discovered a new characteristic for microporous plastics
