THE REJECTION
Claims 1-4, 7, 9, 14-18, 21, 22 and 31 stand rejected under
35 U.S.C. § 103 as being unpatentable over Stoner.
OPINION
We have carefully considered all of the arguments advanced
by appellant and the examiner and agree with appellant that the
aforementioned rejection is not well founded. Accordingly, this
rejection will be reversed.
Stoner discloses that when the surfaces of a dental cavity
are coated with a metallic film of a metal more positive than tin
in the International Electromotive Series such as silver, gold,
platinum, indium, copper, alloys thereof or alloys with a metal
inert to the system, and then the lined cavity is filled with
dental amalgam, the restoration produced is extremely resistant
to corrosion and has a long lifetime compared to conventional
