Appeal No. 96-2162
Application No. 08/265,561
Representative independent claim 4 is reproduced as
follows:
4. A piezoelectric actuator capable of providing
independently controllable motion in first and second
angularly disposed planes, comprising:
a first piezoelectric dimorph having a pair of ground
electrodes and an active electrode oriented so as to cause an
electrical potential across said piezoelectric portion and
move said first piezoelectric dimorph in said first plane;
a second piezoelectric dimorph acting in said second
plane angularly with respect to the first plane, and said
second piezoelectric dimorph being in direct physical and
conductive electrical contact with a ground electrode of said
first piezoelectric dimorph; and
means for independently controlling an electric field in
each of said first and said second piezoelectric dimorphs to
produce said independent movement in said first and second
piezoelectric dimorphs.
The examiner relies on the following references:

Claims 4, 6, 7 and 9 through 14 stand rejected under 35
U.S.C. 103 as unpatentable over Heinz in view of Staufenberg.
