Appeal No. 2007-0484 2
(a) has at least two panel domains having different average
compressive strengths;
(b) is essentially free of a combination of hollow and solid foam
strands;
(c) has an essentially uniform panel thickness;
(d) fits fully within a cavity defined by cavity walls and, when
in said cavity, the building panel has a compressive
recovery that supplies sufficient pressure against the
cavity walls to frictionally retain the building panel
within the cavity, said pressure being 100 Newtons-
per-square-meter or more and 200,000 Newton-per-
square-meter or less;
and wherein, if said panel has at least two adjacent panel domains
containing fibrous material with a fiber orientation, the fiber
orientation of one panel domain is nonorthogonal to the fiber
orientation of at least one adjacent panel domain and wherein the
panel has an edge containing a panel domain extending from a
primary face to an opposing face at that edge and wherein the panel
has a primary face, a face opposing the primary face, a panel
thickness, and a slit penetrating to a depth less than the panel
thickness that traverses and severs the primary face or the face
opposing the primary face.
Claim 22, which depends from claim 1, adds the further limitation that "the panel
domains extend through the thickness of the panel."
Rejection
Claim 1 and claim 22 have both been finally rejected3 as having been
obvious in view of:
Hans Walendy et al., "Filler body as molded part for sealing poorly
accessible hollow spaces", U.S. Patent 5,529,824 (issued 25 June
1996); and
Edgar R. Ducharme, "Insulating insert for the cores of building
blocks", U.S. Patent 5,062,244 (issued 5 November 1991).
3 Final Office Action (FOA) at 3.
