Appeal No. 94-3812
Application 07/857,701
coating compositions for metals containing silica gel. The
examiner concludes that:
It would have been obvious to employ the polyacrylamide
of Reilly, Jr. as the polyacryloyl monomer of Bilkadi
considering the equivalency between the polyacryloyl
esters of Bilkadi and polyacrylamide established in
Reilly, Jr. for equivalent colloidal silica-containing
metal coating formulations.
We disagree.
In the first instance, Reilly, Jr. does not teach the
equivalence of polyacryloyl esters of Bilkadi and
polyacrylamides. Reilly, Jr. describes Micheler ketone
analogs (MKA's) as photoinitiators for addition-polymerizable
compounds. Useful water-insoluble polymerizable compounds
include compounds which could be described as polyacryoyl
esters. The acrylamides disclosed by Reilly, Jr. as useful
are described as water-soluble polymerizable compounds. Thus,
except for the fact that each of the aforementioned compounds
may be polymerized by the MKA's, it is not understood where
the alleged "equivalence" for Bilkadi's coating composition is
found. Further, the silica gel in the example in column 12 of
Reilly, Jr. is only used at a level of about 5 weight percent.
Accordingly, we find that the appealed claims would not have
been obvious from the claims of Bilkadi considered with
