Appeal No. 1997-3548
Application No. 08/457,200
coatings, the examiner has not established that the silicon
oxide and aluminum oxide coatings are equivalent for the
purpose of utilizing them in a polymeric binder which is a
component of a magnetic recording medium. It is the
examiner's burden to demonstrate the purposes for which
silicon oxide and aluminum oxide coatings are equivalent, and
why one of ordinary skill in the art would have recognized
that the claimed aluminum oxide coating is an equivalent for
the silicon oxide coating of the Homola patents which are a
component of a magnetic recording medium.
In conclusion, based on the foregoing, the examiner's
decision rejecting the appealed claims is reversed.
