produced." The second declaration by Close (executed December
18, 1995; Paper No. 13) further states that the declarant
works from a wheel chair and that the "Kasa-Djukic easel" may
be adjusted without disrupting work via a push button control
unit in such a manner that the "far corners of very large
canvases" are reachable. The declaration by Ross (executed
December 19, 1995; Paper No. 13)
states that the "Kasa-Djukic easel" is very easy to adjust and
allows an artist to reach the "far corners of very large
canvases." Thus, according to the declarant, there is no need
to call studio assistants in order to move a painting. The
declarant further states that "I will install a Kasa-Djukic
easel in my studio immediately."
It is apparently the appellant's position that these
declarations establish satisfaction of a long-felt need. Even
if it is assumed that the "Kasa-Djukic easel" is the easel
which is disclosed and claimed in the instant application, we
must point out that, in general, in order to establish long-
felt need evidence must be presented which demonstrates the
existence of a problem which was of concern in the industry
