Appeal 2007-2814
Application 10/215,174
BACKGROUND
The Specification describes a litter composition comprising “a
substantially particulate silica gel material and a binding agent, the binding
agent comprising in the range of approximately 0.01% - 40% of the litter
composition” (Specification 3). The binding agent “induce[s] or facilitate[s]
agglomeration” (id. at 5).
The litter composition may also include fixing agent (id. at 3). The
fixing agent is preferably water-soluble and “facilitates coating of the
moisture activated binding agent to the litter particles” (id. at 6).
DISCUSSION
1. CLAIMS
Claims 1-17 and 19-59 are pending and on appeal. We will focus on
claim 1, which reads as follows:
1. A particulate litter composition, comprising:
a substantially particulate silica gel material; and
at least one binding agent adhered to said silica gel
material with a substantially water soluble fixing agent to form
a scoopable particulate litter composition;
wherein said binding agent comprises approximately
0.01%-40% of said litter composition and said binding agent
facilitates agglomeration of said silica gel material when wetted
such that the portion of silica gel material that agglomerates is
removable as a clump from the remaining litter composition.
Thus, claim 1 is directed to a litter composition comprising
substantially particulate silica gel material and binding agent. The binding
agent is adhered to the silica gel material with a fixing agent.
