Appeal No. 1996-0858 Page 11
Application No. 08/117,648
toweling product that is prepared by essentially the same
method as the prior art product with the specified exception
of the weight amount of aqueous cellulase solution applied to
the toweling and the length of time of the application. In
both the admitted prior art product production method
(comparative Example A, for example) and the claimed product
preparation process, the applied cellulase enzyme is removed
and/or inactivated by subsequent steps such as rinsing and
drying. Thus, the only apparent potential difference(s) in
the respective products is whether the different methods of
application of the cellulase solution result in products
having diverging properties. However, no particular product
characteristics or properties are specifically required by
claim 17 so as to differentiate the claimed product from the
admitted prior art. We note that claim 17 is not limited to a
product prepared by the method of example 1 of the
specification such that the tensile strength and absorbency
properties reported for example 1 of the specification could
be imputed to the claimed product. In this regard, we observe
that the toweling product of example 1 was prepared by a
method that included using cotton terry cloth that was sprayed
