Appeal No. 98-0054
Application No. 08/438,888
Appellant’s invention relates to a unitary mattress
(claims 1-3) and to a method of constructing a mattress
(claims 7 and 8). As recited in the appealed claims, the
mattress comprises a plurality of strings (34) of
pocketed coil springs (30) defining a unitary and hence
undivided core (20). According to appellant’s invention,
the coil springs on one side of an imaginary line (50)
medially intersecting the mattress have one compressive
strength or stiffness, and the coil springs on the other
side of the imaginary line have a different compressive
strength or stiffness, thereby providing two sectors (46,
50) of different degrees of firmness in a single unitary
core. The independent claims on appeal, namely claims 1
and 7, both expressly recite that the strings of coil
springs on opposite sides of the imaginary dividing line
are connected directly together along the imaginary line
without a discontinuity to further establish the unitary
aspect of the core.
A copy of the appealed claims is appended to
appellant’s brief.
