Appeal No. 2005-2005
Application 10/273,845
This is a decision on appeal under 35 U.S.C. § 134(a) from
the final rejection of claims 1-25.
We reverse, but enter a new ground of rejection.
BACKGROUND
The invention relates to a cable that has a lower weight
than conventional cables because the outer sheath which surrounds
the core of the cable has the same thickness as conventional
cables but is lighter due to the enclosed gas bubbles which
result from expanding a layer of the material of the outer
sheath; i.e., the sheath is made from an "expanded material."
Claim 1 is reproduced below.
1. A cable having a core, which is surrounded by an
external extruded sheath, the core comprising at least one
transmission element for the transmission of electrical
current or telecommunication signals, characterized in that
the sheath (M) comprises at least one flexible layer (2) of
a conventional, expanded material, this material having a
tensile strength between 10.0 MPa and 50.0 MPa.
