Appeal No. 97-1445 Page 5
Application No. 08/202,254
shall decide the appeal of these claims on the basis of
representative claim 19, with claims 7, 16 and 18 standing or
falling therewith.
Kaplan (Figure 9) discloses a building wall corner
comprising four curvilinear building blocks (102), shown in
greater detail as curvilinear block (40) in Figure 4. The
curvilinear building block comprises an outer curvilinear
surface (41) opposite an inner surface (42), top and bottom
surfaces and two side ends (39). The curvilinear building
block is provided with "yin yang elements" (44) comprising
female recesses and complementary male projections for
interlocking adjacent building blocks to one another. Kaplan
discloses that the interlocking arrangement of the building
blocks permits them to be assembled without the use of mortar
(column 1, lines 13 through 22 and column 2, lines 61 through
68).
The appellant asserts that Kaplan does not anticipate
independent claim 19 because Kaplan does not disclose a wall
corner composite which includes at least one curvilinear
building unit that is joinable to another masonry building
