Appeal 2006-2300
Application 10/615,746
The invention relates to a fabrication process for producing reinforced
polymeric foam composites. Claim 1 is illustrative of the invention and is
reproduced below:
1. A process for fabricating a fiber reinforced polymeric foam
composite comprising introducing a foamable mixture into a low binder
fiber mat and then expanding the foamable mixture into a polymeric foam
between top and bottom facing sheets such that the fibers of the low binder
fiber mat become dispersed within the polymeric foam, wherein the low
binder fiber mat is part of a first composite web that further comprises a
support mat and wherein a roll of first composite web is used to supply the
process with the first composite web.
The Examiner relies on the following prior art references to show
unpatentability:
Londrigan US 5,837,743 Nov. 17, 1998
Hoffmann US 4,804,425 Feb. 14, 1989
The Examiner made the following rejection:1
Claims 1-13 and 20 under 35 U.S.C. § 103 as unpatentable over
Londrigan in view of Hoffmann.
BACKGROUND
The Examiner contends that Londrigan discloses the invention as
claimed with the exception of a supply roll of composite comprising a low
binder fiber mat and a support web (Answer 5). The Examiner further
contends that it would have been obvious to have replaced the two
individual supply rolls of low binder fiber mat and support mat in
1 The rejection of claims 1-13 and 20 under 35 U.S.C. § 103 as unpatentable
over Gluck in view of Hoffmann has been withdrawn (Answer 2). The
rejection of claims 14-16 under 35 U.S.C. § 103 as unpatentable over
Londrigan in view of Hoffmann has also been withdrawn (Answer 3).
