Appeal No. 2007-1237
Application No. 10/813,367
BACKGROUND OF THE INVENTION
The Appellants' invention relates to a cable comprising one or more electrical
conductors or communications media comprising: (a) polyethylene; polypropylene;
or mixtures thereof; (b) carbon nanotubes; and (c) a conductive carbon black other
than carbon nanotubes. An understanding of Appellants' invention can be derived
from a reading of exemplary claim 1, which is reproduced from the Brief below:
1. A cable comprising one or more electrical conductors,
communications media or a core, each electrical conductor,
communications medium, or core being surrounded by a layer
comprising:
(a) polyethylene; polypropylene; or mixtures thereof;
(b) at least about 3 parts by weight, based on the weight of
component (a), carbon nanotubes;
(c) a conductive carbon black other than carbon nanotubes, the
carbon black present in an amount at least about 10 parts by weight,
based on the weight of component (a); and
(d) optionally, (i) a copolymer of acrylonitrile and butadiene
wherein the acrylonitrile is present in an amount of about 30 to about
60 percent by weight based on the weight of the copolymer or (ii) a
silicone rubber.
