Appeal No. 95-0876
Application 08/006,517
The examiner has rejected claims 1 to 10, 13 to 15, and 17 to 24 under 35
U.S.C. § 103 as unpatentable over Esmay. According to the examiner, Esmay teaches a
method of making a double-coated adhesive tape comprising applying a first adhesive to
an elongated tape substrate first face and applying a second adhesive coating to the
second substrate face and rolling the substrate into a roll. The examiner further states that
Esmay teaches that one or both adhesive coatings may be releasable. The examiner
recognizes that Esmay does not require the provision of a single release liner for his
double sided adhesive tape when it is placed in a spiral roll. However, the examiner is of
the view that the provision of a release liner to a double sided adhesive tape is old and
well known in the adhesive tape art. Therefore, it is the examiner’s determination that it
would have been obvious to one skilled in the art to place a releasable liner on the
adhesive tape of Esmay prior to rolling up the tape. The examiner’s motivation for this
combination is that one of ordinary skill in the art would expect the release liner to function
in its art recognized capacity.
With respect to claims 2, 15, and 23, the examiner recognizes that Esmay does not
disclose a spaced separation-facilitating means. However, the examiner is of the opinion
that it well known in the art to provide such a means and it would have been obvious to
include such a means in the Esmay tape as modified by the examiner.
