Appeal No. 96-1952
Application No. 08/163,778
The examiner finds that Farrar discloses a blend of
polymers where the “first polymer is the reaction product of
‘one or more’ dialkylaminoalkyl (meth)acrylate or
(meth)acrylamide monomers or the quaternized ammonium forms of
those monomers, with diallyldialkyl ammonium chloride (DADMAC)
monomers.” The examiner further finds that the second polymer
of Farrar is a reaction product of the same monomers, but in
different proportions (see the Answer, page 3, citing Farrar,
column 2, ll. 3-28, column 4, line 38 to column 5, line 10,
and Example 2 bridging columns 8 and 9).
The examiner has not cited any support for the factual
finding that Farrar discloses, as either the first or second
material, a reaction product of “one or more”
dialkylaminoalkyl (meth)acrylate (such as DMAEMA,
dimethylaminoethyl methacrylate, see Farrar, column 8, ll. 40-
41) or (meth)acrylamide monomers with DADMAC monomers. Farrar
discloses DADMAC as one material and DMAEMA as the other
(second) material but there is no disclosure cited to teach or
suggest the specific three monomers required as a minimum by
claim 1 on appeal (see Example 2 of Farrar).
