Appeal No. 1998-1308
Application No. 08/469,397
the Wolf disclosure does not anticipate or render obvious
claims 1 and 3. The combined disclosures of Brambach and Wolf
do not render obvious claims 1, 3, 6 or 7, nor does the
combined disclosure of Brambach, Wolf , and the admitted prior
art render obvious
claim 4. Therefore the rejections on appeal are reversed.
Our reasons follow.
Turning to the patent of Wolf, we agree with the examiner
that Wolf discloses a polyurethane foam core board for use in
fabrication of a sandwich panel. Wolf discloses that the
bounce properties of the ping-pong table made from the panel
can be improved by the provision of a regular rectangular
pattern of narrow grooves formed in the faces of the panel.
Wolf discloses a rectangular pattern and states that this
pattern is preferred. Wolf further states that the grid
pattern may be non-rectangular, in which case the grooves may
intersect at an angle of between 40 and 90 degrees.
On the other hand, we are in agreement with appellants
that Wolf does not disclose three series of indentation with
each series intersecting indentations of the other series at
4
