Appeal No. 1998-1060
Application No. 08/433,664
Appellants argue that APA fails to teach the use of an
alkoxy compound of the metal to form the metal oxide (brief-
top of page 5) and Kojima fails to teach forming the silicon
dioxide from alkoxysilane and the metal oxide from an alkoxy
compound of the metal. Further, Kawamura fails to teach
forming the metal oxide by heating an alkoxy derivative of the
metal (brief-top of page 6).
Claim 5 recites that the silicon dioxide is formed from
heating the alkoxysilane compound, and the metal oxide is
formed from heating the alkoxy compound of the metal. We note
that APA does teach forming the silicon dioxide from heating
the alkoxysilane compound (as indicated by the Examiner).
However, Appellants are correct in that APA does not teach
forming the metal oxide from an alkoxy compound of the metal.
Appellants are further correct in that Kojima and Kawamura
also fail to teach forming the metal oxide from an alkoxy
compound of the metal. Even though Kawamura teaches the
desirability of using a metal oxide in the filtering layer of
a cathode ray tube coating, we see no teaching of the claimed
