portions with weakened material allowing the body to be configured to fit
different shapes or platens?
Based on the totality of this record, we determine that the Examiner
has established a prima facie case of obviousness based on the reference
evidence, which prima facie case has not been adequately rebutted by
Appellants’ arguments. Therefore, we AFFIRM both grounds of rejection
presented in this appeal essentially for the reasons stated in the Answer, as
well as those reasons set forth below.
OPINION
We determine the following Factual Findings from the record in this
appeal:
(1) Martin discloses an abrasive sheet for a sanding machine
comprising a body portion and a tip portion with a working point,
where the tip portion is defined by a weakened region so that the
tip portion can be separated from the body portion, turned through
an angle and re-positioned to provide a plurality of new working
points for extended use (Abstract; Figs. 1-2; col. 1, l. 44-col. 2,
l. 2; and col. 3, ll. 1-14);
(2) Martin teaches that many hand-held electric sanders are well
known, conventionally designed to carry rectangular sand paper
sheets of quarter size, third size, or half size (col. 1, ll. 12-15);
(3) Martin teaches that if the tip portion includes four working points,
the tip portion is preferably substantially square but tip portions
having two, three, five, six, seven, etc., working points
alternatively can be employed (col. 2, ll. 3-4; and col. 3, ll. 26-28);
