Appeal No. 2006-0737
Reexamination Control No. 90/005,944
Reexamination of U.S. Patent No. 4,847,448
I(A). The Rejection of Claims 1 and 7 Under 35 U.S.C. § 103(a)
Claims 1 and 7 stand rejected under 35 U.S.C. § 103(a) as
being unpatentable over JP ‘321 in view of JP ‘622.
The examiner has found that JP ’321 describes a coaxial cable
having a central conductor, an insulation layer formed on the
conductor, a laterally wound shielding layer formed of a plurality
of wires wound at a predetermined pitch around the insulation
layer, and a metal tape wound over the shielding layer, the tape
including a plastic tape and a metal layer disposed on the tape,
the metal layer being in contact with the shielding layer.
The examiner has also found that JP ‘622 describes a coaxial
cable with an insulating layer which can be formed by an extrusion
process or by an insulating tape that is laterally, i.e. spirally,
wound around the periphery of the central conductor.
The examiner thus concludes that it would have been obvious
to one of ordinary skill in the art at the time the invention was
made to modify the insulation layer of JP ‘321 by using an
insulation tape and laterally winding the insulation tape around
the central conductor to improve the flexibility of the cable.
The examiner has additionally found that forming an insulating
layer around a conductor by winding a tape around the conductor is
a known way of insulating a conductor. (Examiner’s Answer, pages
