Appeal 2007-0291
Application 09/976,412
(1) Paley discloses a wiper for use in a cleanroom where the
wiper is preferably made from knitted polyester, and the
wiper has a fused border around the periphery of the wiper
with sufficient area and tear-strength to maintain segments
of the material therein which otherwise might be released
during use, with the border being small enough to maintain
pliability and absorbency (col. 1, ll. 4-10 and 56-61; col. 2,
ll. 4-22 and 57-60; and col. 3, ll. 29-58; Answer 3);
(2) Paley teaches that severing the fabric to make the wiper
leaves a cut edge along which there are free segments of the
filaments that can be released into the ambient atmosphere
and contaminate the environment (col. 3, ll. 1-10);
furthermore, Paley teaches that “localized melting of the
segments 26 is insufficient to prevent the segments 26 from
release when subjected to agitation and other manipulations
common in the use of the wiper” (col. 3, ll. 10-17);
(3) Langley teaches that, in the field of cleanroom garments,
formation of bonded seams avoids the release of
microscopic fiber particles as a source of contamination
(col. 1, ll. 8-10, 32-40, and 62-64);
(4) Langley teaches that cleanroom garments provide an
effective barrier to release into the environment of
microscopic particles from the human body and from inner
clothing when the seams are bonded over folded-over edges
