I(B). New Ground of Rejection of Claims 1 and 7
Under 35 U.S.C. § 103(a)
Claims 1 and 7 are newly rejected under 35 U.S.C. § 103(a) as
being unpatentable over JP ‘321 in view of JP ‘622, Townsend, and
Leef.
As to claims 1 and 7, JP ’321 describes a shielded coaxial
cable (Translation, page 2, line 11-12) having a central conductor
1, an insulation layer 2 formed on the conductor, a laterally
wound shielding layer 5 formed of a plurality of wires wound at a
predetermined pitch around the insulation layer, and a laminated
metal tape wound or wrapped over the shielding layer, the tape
including a plastic tape and a metal layer in contact with the
shielding layer (Translation, page 2, lines 11-17)(See also
Figures 1 and 2).
JP ‘622 describes a coaxial cable with an insulating layer
which can be formed by an insulating tape that is laterally, i.e.
spirally, wound around the periphery of the central conductor.
(Page 2, lines 10-11). Townsend notes that conductors spirally
wrapped with tape material are “commonly used” in electrical
equipment. (Column 1, lines 24-25). Townsend’s spiral wrappings
are to “. . . wrap a conductor with an insulative spiral wrapping
that is flexible and will not break or expose the conductor when
