Application No. 09/183,114
The adhesive tape described in Kreckel and Korpman can be used for
medical application such as bandages. See Kreckel, page 11, line 3
and Korpman, column 1, lines 41-42. This adhesive tape, according
to column 1, lines 41-50, of Korpman, is advantageous in that it
can be removed without pain from the skin due to both the high
extensibility and easy stretchability of the film-adhesive
laminate.
Although both Kreckel and Korpman is silent as to coating a
pressure sensitive adhesive composition on at least one surface of
a backing material in a plurality of discrete and discontinuous
areas as indicated supra, Takemoto teaches at column 7, lines 10-
21, various advantages in using a plurality of discrete and
discontinuous pressure sensitive adhesive coatings on at least one
surface of a backing material of a medical bandage. The backing
material taught by Takemoto embraces those described in Kreckel and
Korpman. See column 2, lines 19-20 and column 5, line 54 to column
6, line 4.
Given the above teachings, we determine that one of ordinary
skill in the art would have been led to employ the plurality of
discrete and discontinuous pressure sensitive adhesive coatings
taught by Takemoto on the surfaces of the backing materials of the
type described in Kreckel or Korpman, motivated by a reasonable
