Appeal No. 2003-0091
Application No. 09/298,640
The relevant portion of the appellant’s original disclosure
is the passage on page 5 of the specification which states that
[a]n adhesive layer (not shown) may be used to
mount the exterior and/or interior transparent sheets
14 and 16 on the penetration resistant sheet 20. The
adhesive layer is preferably substantially co-extensive
with the exterior and interior glass transparent sheets
14 and 16. Any suitable type of adhesive layer may be
used, provided that it adequately secures the exterior
and interior transparent sheets 14 and 16 to the
penetration resistant sheet 20, and does not decrease
light transmission through the window 10 to an
undesirable extent. The optional adhesive layer may
comprise polyurethane, PVB or silicone, with
polyurethane being preferred in many applications.
There is no indication here that the appellant contemplated
using a double sided tape to secure the penetration resistant
sheet between the two transparent glass sheets, or that a double
sided tape would fall within the group of adhesives listed by the
appellant. More importantly, the passage clearly states that the
use of an adhesive layer (such as a double sided tape) to mount
the exterior and/or interior transparent glass sheets to the
penetration resistant sheet is optional. Thus, the disclosure of
the application as originally filed would reasonably convey to
the artisan that the appellant had possession at that time of a
laminated glass window as recited in claim 22 wherein the
penetration resistant sheet is secured between the glass sheet
