Appeal No. 95-0318
Application 08/031,046
Scheuerlein also teaches that heating the composition to a
temperature which decomposes the formaldehyde powder without
effecting a change in the density of the polyimide phase of the
preform, and results in a pore structure of the polyimide
corresponding substantially identically to the particle size of
the formaldehyde polymer, is further evidence that the polyimide
of the reference does not enter into a copolymerization reaction
with the formaldehyde polymer. Furthermore, we are not satisfied
that the examiner has assigned appropriate probative value to the
Rule 1.132 Declaration of Dr. Volksen, a Ph.D. chemist who has
performed research since 1977 in polymer dielectrics,
particularly polyimides. The declaration of Dr. Volksen includes
his opinion that “no copolymer of polyimide and
poly(paraformaldehyde) is formed during the process of
Scheuerlein to form the porous polyimide article,” as well as
scientific reasons in support of the opinion.
Based on the foregoing, the examiner’s decision rejecting
the appealed claims is reversed.
