endeavor and, if not, whether it is reasonably pertinent to the

are informed by the appellant's originally filed specification
(p. 3) that by practicing the method of the present invention, a
bladder can be fabricated quickly, easily, and at low cost. The
method that accomplishes those results is stated to involve
selectively forming a number of chambers with an elastomeric
material, such that each chamber is in fluid communication with
the others. Thereafter, the interior is supplied with an amount
of fluid, so that the chambers are all pressurized at the same
desired level. The fluid communication is then sealed so that
each of the chambers is separated from the other chambers. Casey
teaches (1) that inflatable cushions can easily be prepared which
have individual chambers in any of a large variety of desired
