Appeal No. 97-3289
Application 08/550,895
manifested in three independent claims, the broadest of which
is claim 18. This claim is directed to an inflatable air
mattress comprising a woven textile top sheet, an inner
plastic sheet laminated to the top sheet and made with
plasticizers, a bottom plastic sheet, and a plurality of
beams, wherein the inner plastic sheet and the bottom plastic
sheet are bonded by lap seams. The examiner finds the basic
structure in Nail, and looks to Walker, Brock and Fraige for
the remaining features, concluding that it would have been
obvious to one of ordinary skill in the art to modify Nail in
such a manner as to meet the terms of the claim.
Nail discloses an inflatable air mattress comprising
a top plastic sheet 2, a bottom plastic sheet 3, and a
plurality of beams 11. The top and bottom plastic sheets are
sealed together along edges 6 and 7, and the beams are sealed
to the top and bottom sheets (column 2, lines 16-19 and 38-
41). Nail does not disclose or teach a woven textile top
sheet laminated to the top plastic sheet, or that the top
plastic sheet is made with plasticizers and is bonded by lap
