Appeal No. 2001-2187
Application No. 09/333,356
The References
In rejecting the claims under 35 U.S.C. § 103(a), the
examiner relies upon the following references:
Coggin, Jr. (Coggin) 3,988,135 Oct. 26, 1976
Demaschquie 4,421,538 Dec. 20, 1983
The Rejections
Claims 1-2 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Demaschquie in view of Coggin.
The Invention
The invention relates to an apparatus for forming fibers from
high-temperature fusing batch material. It is said to provide an
in-line process for the direct production of high-temperature
resistant glass fibers. A top-charging electric glass-melting
furnace is positioned vertically above a bushing plate containing
apertures through which fibers are extruded, and an intermediate
flow regulating baffle system. (Specification, page 1, lines 5-
10). The baffle system and flow system are described further in
claim 1, reproduced above.
The Rejection of Claims 1-2 Under 35 U.S.C. § 103 (a)
The examiner has found that Demaschquie discloses the wall
melting receptacle with heating unit, and Coggin teaches superior
bushings. (Examiner’s Answer, page 3, lines 13-15). The examiner
concludes it would have been obvious to provide the Demaschquie
