Application No. 08/293,331
to thereby obtain the coated product which is the subject of
the appealed
claims. According to appellant's specification, the silica
coating does not have essentially any Si-H bonds (appellant's
specification, Example 1).
Mine claims a method of forming a film (coating) by
providing a film of a hydrogen silsesquioxane resin on a
substrate using a solvent solution, removing the solvent, and
heating the resin film in an inert atmosphere to a temperature
of between 250 up to, but not including, 500°C to reduce
hydrogen in the film to less than 80% of that in the resin
used (Mine, claims 1 and 2). An electrical device such as a
semiconductor may be used as the substrate to be coated in the
claimed process of Mine (claim 4).
In view of the above, and a comparison of the claims of
Mine and the appealed claims, we agree with the examiner that
the product of the appealed claims encompasses and would have
been prima facie obvious from the product produced by carrying
out the claimed process of Mine. Compare In re Best, 562 F.2d
