Appeal No. 2001-1666
Application 08/818,333
The appellant’s admitted prior art relied upon by the
examiner (answer, page 6) is the statement that “[s]ome tile
installers have used a paper or fabric backing to hold a pattern
of tiles together but this has been done with the gluing as a
separate step and requires waiting for the glue to dry before the
tile assembly can be moved” (page 1, lines 16-19).
Du Fresne discloses an offsite process wherein tiles are
placed face down in a matrix, a resin emulsion adhesive is
sprayed onto the backside of the tiles, an open mesh woven fabric
is placed on the adhesive, the adhesive is cured, and the backing
is folded onto itself to form a compact unit for shipment and
ready installation (col. 3, line 25 - col. 4, line 8). The
exemplified dimensions of the matrix are 2 to 4 feet wide and 4
to 8 feet long (col. 3, lines 34-35).
Worth discloses a process wherein paper, linen, or other
suitable fabric or material, having any number of holes or
perforations, is cemented or pasted to the rear faces of tiles
having varying sizes and shapes, to form pre-assembled tiles for
application to a surface by a tile installer (page 1, lines 14-28
and 59-72; page 2, lines 3-45).
