Appeal No. 1998-2551 Page 8
Application No. 08/787,624
reference of record to Eschenbach clearly teaches what one of
ordinary skill in the art would have understood the appellant
to mean by his use of the phrase "core and effect yarn."
Eschenbach teaches that a "core and effect yarn" is a novelty
yarn produced by combining a core yarn 10 and an effect yarn
12 in an air jet 14 such that the combined yarn 16 (i.e., the
"core and effect yarn") has slub sections 51, lean sections 52
and nubs 54 containing loops 53. Thus, it is our view that
the broadest reasonable meaning of a "core and effect yarn" as
used in claim 47 is a yarn combined from a core yarn and an
effect yarn.
It is our determination that the yarn taught by American
Viscose at page 2, lines 85-91, is not readable on being a
core and effect yarn. In that regard, the loops in the yarn
taught by American Viscose are formed by a stream of air that
causes some of the filaments to be blown out of the strand of
aligned filaments. Thus, the yarn taught by American Viscose
does not have an effect yarn and therefore is not a "core and
effect yarn."
