anionic, cationic, amphoteric, and nonionic polymers of
chitosans; cellulose polymers chosen, for example, from
hydroxyethyl cellulose, hydroxypropyl cellulose, methyl
cellulose, ethyl hydroxyethyl cellulose, carboxymethyl
cellulose, and quaternized derivatives of cellulose;
acrylic polymers and acrylic copolymers, such as for
example, polyacrylates and polymethacrylates; vinyl
polymers, chosen for example, from
polyvinylpyrrolidones, polyvinyl alcohols, copolymers
of methyl vinyl ether and maleic anhydride, copolymers
of vinyl acetate and crotonic acid, copolymers of
vinylpyrrolidone and vinyl acetate, and copolymers of
vinylpyrrolidone and caprolactam; and optionally
modified polymers of natural origin chosen, for
example, from gum arabic, guar gum, xanthan
derivatives, karaya gum, alginates carrageenans,
glycosaminoglycans shellac resin, sandarac gum,
dammars, elemis, copals, deoxyribonucleic acid,
mucopolysaccharides such as for example, hyaluronic
acid, and chondroitin sulphate, and hyaluronic acid
derivatives.
The examiner has simply not convincingly explained why,
under the facts of the present case, the original disclosure,

examiner has not discharged the burden of establishing that the
application, as originally filed, inadequately describes the
subject matter in question by not giving examples of particular
polymers within each category of polymers recited in claim 44 as
part of the claimed composition. After all, the specification is
directed to those skilled in the art. The examiner has not
