Appeal No. 1997-1896
Application No. 08/476,389
BACKGROUND
The appellants’ invention relates to a slotted core telecommunications cable. An
understanding of the invention can be derived from a reading of claim 20, which is
reproduced below.
20. A telecommunications cable, comprising: a longitudinally extending
spacer having at least an outer layer thereof formed of plastic material
having a melt flow index of equal to or greater than about 0.65 g/10 min, said
spacer having formed in said outer layer a plurality of longitudinally extending
helical grooves each for supporting a longitudinally extending
telecommunications member therein, each of said grooves having a cross-
sectional shape transverse to its longitudinal extent generally in the form of
an U-shape with a flat bottom, two corners, and two walls, each wall
substantially perpendicular to said bottom and joined to said bottom at one
of said corners, and a plurality of longitudinally extending ribs each between
two adjacent grooves and each delimiting two of said groove walls, each rib
having a longitudinally extending base between adjacent groove corners
whose thickness does not exceed about 1.3 mm; and an outer jacket
surrounding said spacer.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
Rawlyk 5,188,883 Feb. 23, 1993
Brosius et al. (Brosius) 5,371,144 Dec. 06, 1994
Claim 20 stands rejected under 35 U.S.C. § 103 as being unpatentable over
Rawlyk in view of Brosius.
