Appeal No. 1997-0230
Application No. 08/416,668
Yount discloses a method for making releasable laminates by
coating a water-dispersed PSA onto either a web of paper face
stock or a web of release paper, joining the two webs together
with the adhesive therebetween while the adhesive is still wet,
and then drying the laminate (col. 1, line 66 - col. 2, line 5;
col. 3, lines 60-61). Yount joins the webs together before the
adhesive is dried to minimize wrinkling which would result from
drying the paper face stock and release paper under different
drying conditions (col. 2, lines 36-43). Also, Yount controls
the moisture level of the dried laminate to minimize wrinkling
of the laminate (col. 2, lines 28-43).
Appellants argue that Yount would not have fairly
suggested, to one of ordinary skill in the art, drying the
adhesive and then contacting the dried adhesive with the paper
face stock because doing so would be expected to cause wrinkling
(brief, page 3). Also, appellants argue that Yount would not
have led such a person to apply the method to porous carpet
underlayment pads (brief, pages 4-5).
Regarding appellants’ argument that Yount would not have
led one of ordinary skill in the art to dry the adhesive and
