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."Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
