to reduce dependence upon tantalum. A film of titanium
hydride and aluminum is heat treated to produce
dehydrogenation in the process of forming the porous body.
The Rejection under 35 U.S.C. § 103
The examiner’s position is that “It would have been
obvious to one of ordinary skill in the art to replace the
solid capacitor element of Nakata with the element of Kubo to
diminish the dependence on tantalum.”
After consideration of the positions and arguments
presented by both the examiner and the appellants, we have
concluded that the rejection should not be sustained.
It is considered that means for altering stresses in a
body of solid material is not taught by the combined teachings
of the references. Kubo teaches making a porous body for a
solid electrolytic capacitor. The process involves a
dehydrogenation process, which results in a size reduction of
the body produced. After Kubo’s porous body is made, it is
the examiner’s position that it would have been obvious to
insert it as a capacitor in cavity 11 (Fig. 5c) of Nakata and
enclose it in the housing or body comprising resin pieces 7,
15. Although we agree with the examiner that it would have
