Appeal 2007-0851
Application 10/385,213
said internal phase is an aqueous phase emulsion in said
external phase; and
said external phase comprises a silicone matrix.
3. The topical preparation as claimed in claim 1 wherein said droplets
are from about 0.1 µm to about 2000 µm in diameter.
22. The topical preparation as claimed in claim 1 wherein said at least one
hydrophilic component is selected from polyvinyl alcohol and
polyvinylpyrrolidone and combinations thereof.
31. The topical preparation as claimed in claim 1 wherein said internal
phase and said external phase are selected such that said topical preparation
comprises a topical dressing, and wherein said topical dressing comprises a
patch.
Thus, we interpret claim 1 to be directed to a topical preparation
comprising an external phase comprising a silicone matrix and an internal
phase comprising droplets comprising a hydrophilic carrier, another
hydrophilic component, and an active agent.
The term “active agent” is defined in the Specification “as referring to
proteins, and in particular to enzymes” (Specification 5) “Proteins” are
defined as including enzymes, polypeptides, and peptides (id. at 7).
The term “hydrophilic carrier” is defined in the Specification “as
referring to at least one component of a phase of the preparations of the
present invention that acts as the solvent for the active agents” (id. at 6-7).
Thus, the hydrophilic carrier is hydrophilic and acts as a solvent.
The term “hydrophilic component” is defined in the Specification as a
“component added to the mixture of the hydrophilic carrier and active agent
