Appeal No. 2003-2153 Page 10
Application No. 09/632,160
invention was made to combine the intermittent adhesive to the optical fiber cable as
taught by Keller et al with the reinforced cable disclosed by Hager et al."
The appellants argue through both briefs that the applied prior art does not
suggest the claimed subject matter. We agree.
In our view, the teachings of Keller provide no teaching or suggestion for a
person of ordinary skill in the art at the time the invention was made to have applied
adhesive onto Hager's optical fiber core intermittently in the lengthwise direction thereof
so as to intermittently bind Hager's optical fiber core 10 to the yarn 20. While Keller
does teach the alternate use of either cycled (i.e.,intermittent) thermoset material such
as a low viscosity elastomer or cycled fiber locks to bind an optical fiber to a buffer
tube, Keller does not teach or suggest an optical fiber cable having buffer members
composed of a long fiber longitudinally disposed or stranded around an optical fiber
core wherein the buffer members and the optical fiber core are adhered together
intermittently in the lengthwise direction, and an outer covering surrounding the buffer
members.
