Appeal No. 2001-0206
Application 08/959,964
pressure to the sub scrotal area by providing two
split support portions but, by providing the
particular and critical shape of the surface area of
the support portions 10 and 11, eliminates any other
areas of high pressure which could cause discomfort.
The typical single support surface bicycle seat
in use today provides approximately 27 square inches
of support surface for the rider. My improved
bicycle seat preferably provides approximately 22
square inches of support per each support portion 10
and 11, for a total of 44 square inches of support.
However, this fact alone will not, in itself,
provide the increased comfort desired. In order to
make efficient use of the increased support area the
surface must be shaped so that the weight of the
rider is uniformly distributed over the entire
surface. For maximum comfort the ratio between the
highest pressure and the lowest pressure should be
as small as possible.
In order to obtain the proper surface shape for
support portions 10 and 11 it is necessary to
conform the shapes as much as possible to the shape
of the human skeleton in the region of the ischium
and upper femur, the bones which are actually
supported by the seat [column 3, lines 33 through
62].
Anticipation is established only when a single prior art
reference discloses, expressly or under principles of
inherency,
each and every element of a claimed invention. RCA Corp. v.

385, 388 (Fed. Cir. 1984).
Although independent claims 1, 2, 10, 18, 20, 22, 32 and
33 vary in scope, they all in effect require a bicycle seat
