Appeall No. 1998-1398 Page 13
Application No. 08/400,637
Here, the original specification discloses "a call in
process between the PCC 101 ... and a calling party ...."
(Spec. at 16.) One of ordinary skill in the art would know
that the calling party necessarily used a telephone having a
telephone number to place the call in process.
In view of this disclosure and knowledge, we are not
persuaded that persons skilled in the art would not recognize
in the disclosure a description of the claimed limitations of
“a telephone device having a telephone number ....”
Therefore, we reverse the rejection of claims 27-36 as lacking
a written description. We proceed to the enablement
rejection.
II. Enablement Rejection of Claims 27-30
We begin by noting the following principles. To fulfill
the enablement requirement, a specification must contain a
description that enables one skilled in the art to make and
use the claimed invention. That some experimentation is
necessary does not preclude enablement. All that is required
