Appeal No. 97-2359
Application 07/894,260
This is an appeal from the examiner’s final rejection of
claims 70-78 and refusal to allow claims 62-68 as amended
after final rejection. The remaining claims in the
application, which are claims 43-61, 69, and 79-119, stand
free of rejection. Claims 62 and 66 are illustrative and read
as follows:
62. A controllably dissociable aggregate cluster
comprising a cluster of inorganic oxides of substantially
mono-dispersed particle size which are coated with a
functionalized organic moiety wherein the cluster is bonded
together by chemical interaction between the functional groups
of said organic moiety.
66. A controllably dissociable aggregate bead cluster
which comprises:
a cluster of inorganic oxide particles of substantially
mono-dispersed particle size associated with a macromolecular
species, characterized in that said particles are encapsulated
by the macromolecular species forming a bead, the
macromolecular species containing an organic functionality to
link the beads together forming controllably dissociable
chemical bonds.
