Appeal No. 2003-0580
Application No. 09/139,081
THE REJECTION
Claims 41-52 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Lin in view of Jenkins, Chambers, Ida ‘973 and
Ida ‘901.
OPINION
We affirm the aforementioned rejection.
The appellants state that the claims stand or fall together
(brief,2 page 4). We therefore limit our discussion to one
claim, i.e., claim 41. See In re Ochiai, 71 F.3d 1565, 1566 n.2,
37 USPQ2d 1127, 1129 n.2 (Fed. Cir. 1995); 37 CFR § 1.192(c)
(7)(1997).
Lin discloses textile articles, especially carpets,
comprising polyamide sheath-core filaments wherein the sheath is
comprised of a polyamide which is resistant to staining by acid
dyes (col. 1, lines 7-11). An exemplified filament has a
nylon 66 core and a nylon 6,12 sheath, the sheath to core ratio
being 1:9 (col. 5, lines 6-8 and 27). Pigments can be
incorporated into the sheath and/or core polymer (col. 3,
lines 20-24). Lin does not disclose dyeing the filaments.
