Interference 103,685
Holsten’s application Claim 43
A fibrous material formed from fibers selected
from the group consisting of aromatic polyamide fibers,
polybenzimidazole fibers, aromatic polyimide fibers,
fibers of copolymers of the monomers thereof, or blends
thereof which has been dyed with a mixture of a carrier
and a dye soluble or dispersed in a dyebath, the carrier
comprising an N-substituted aromatic carbonamide or an
N,N-disubstituted aromatic carbonamide or mixture thereof.
Senior party Holsten’s patent claims which were designated
as corresponding to the Count 1 at the time the interference
was declared and are deemed to be representative of Holsten’s
claimed invention are (Paper No. 1 (Notice Declaring
Interference), pp. 18-19):
Holsten’s patent Claim 1
A method for dyeing fibrous material comprising the
steps of:
contacting a fibrous material formed from fibers
selected from the group consisting of aromatic polyamide
fibers, polybenzimidazole fibers, aromatic polyimide
fibers, fibers of copolymers of the monomers thereof,
or blends thereof with a dyebath comprising a mixture of a
carrier and a dye soluble or dispersed in the dyebath, the
carrier comprising N,N-diethyl(m-toluamide); and
heating the fiber while in contact with the dyebath to
fix said dye within the fibrous material.
Holsten’s patent Claim 4
A method according to claims [sic] 1 or 2 wherein
the mixture includes a flame retardant.
Holsten’s patent Claim 30
A fiber selected of aromatic polyamides,
polybenzimidazoles, aromatic polyimides, copolymers
