Appeal No. 1997-0635 Page 5
Application No. 08/375,183
Claim 4, the only independent claim on appeal, reads as
follows:
A gang form for molding a natural stone surface
having multiple stone regions, said gang form comprising:
(a) a plurality of form liners each including a
front surface and a back surface, said front surface of
each form liner including only one lateral relief mold
face for contouring a single stone region on a wall
formed against said lateral relief mold face, the lateral
relief mold face including:
(i) a central surface portion located central to
the lateral relief mold face, the central surface
portion having a reverse contour to a single natural
stone for forming a natural stone region in the
wall; and
(ii) a border surface portion contiguous with
and completely surrounding the central surface
portion, the border surface portion having a reverse
contour to a mortar region of a natural stone wall
for forming a mortar region contiguous with and
surrounding the natural stone region in the wall;
(b) a backing member; and
(c) means for mounting said back surface of each of
said form liners to said backing member wherein said form
liners are mounted in an adjacent mating relationship to
create a continuous lateral relief mold face.
In rejecting claims under 35 U.S.C. § 103, the examiner
bears the initial burden of presenting a prima facie case of
obviousness. See In re Rijckaert, 9 F.3d 1531, 1532, 28
