Appeal 2007-3575
Application 10/233,698
Each marginal portion 26, and edge portions 27, however,
contain a plurality of generally parallel layers 28 of adhesive
and plurality of generally parallel regions 30 of lesser
adhesiveness alternating therebetween, so that layers 28 and
regions 30 form a segmented adhesive portion. The regions 30
may be uncoated regions of the tape backing strip, or an
adhesive mixture of lesser adhesiveness than that in layers 28 . .

(Col. 2, ll. 54-65)
Thus, the ordinary artisan would read the description in conjunction
with Figure 2 as disclosing a medical dressing having alternating strips, one
strip of adhesive, and a second strip of adhesive, wherein both adhesives
located directly on the first major surface of the backing, as Economou
specifically teaches that the regions of lesser adhesiveness may be uncoated
regions of the tape backing strip.
That teaching is contrast to the description of Figure 6 at column 4,
lines 38-41, which teaches an alternative embodiment wherein a
conventional tape has been overprinted or coated with a tape of lesser
adhesiveness. There is nothing in the description of Figure 6, which shows
layers of adhesive such that the lesser adhesive is not located directly on the
first major surface of the backing, is also applicable to the dressing shown in
Figure 2.
As to claims 66, 72, and 73, Appellants argue that the claims require
“the second pressure sensitive adhesive [to] comprise[ ] at least one
bioactive agent,” and that collagen is not a bioactive agent in accordance
with the present invention (Br. 9). Appellants argue that bioactive agent as
set forth in the Specification includes drugs, antibiotic agents, antimicrobial
agents, etc., and the Examiner has failed to provide any support for the
