Appeal 2006-2299
Application 10/615,671
first twist, and a resinous coating on the warp and weft yarns having a
coating weight distribution ratio of less than 2.0:1. Independent claim 1 is
illustrative and reads as follows:
1. A fabric reinforcement useful in reinforcing an alkaline matrix
comprising:
(a) a plurality of warp yarns having a first twist (turns/inch);
(b) a plurality of weft yarns having a second twist which is
greater than said first twist; and
(c) a resinous coating disposed over a substantial portion of said
warp and weft yarns after they have been assembled or laid together, such as
to produce a coating weight distribution ratio (WPUcd/WPUmd) of less than
about 2.0:1, before said fabric reinforcement is embedded within, or
adhesively or mechanically bonded to said alkaline matrix.
The references set forth below are relied upon by the Examiner as
evidence of anticipation and obviousness:
Kobayashi US 4,460,633 Jul. 17, 1984
Endo US 4,581,275 Apr. 8, 1986
Wu US 5,038,555 Aug. 13, 1991
Claims 1-5, 7, 9, 22, and 25-29 are rejected under 35 U.S.C. § 102(b)
as being anticipated by, or alternatively under 35 U.S.C. § 103(a) as being
obvious over, Kobayashi.
Claim 23 is rejected under 35 U.S.C. § 103(a) as being unpatentable
over Kobayashi in view of Endo, and claims 6, 8, and 24 are
correspondingly rejected over these references and further in view of Wu.
These rejections cannot be sustained.
