Appeal No. 95-3273
Application 08/136,856
Geil et al. Patent 4,833,659 is repeated in the Answer. In 2
addition to maintaining the rejection based on Geil et al., the
Answer added new grounds of rejection based on Rokurota Patent
4,747,192.
The invention is a piezoelectric microphone structure.
Claim 1, which is one of three independent claims on appeal
(claims 10 and 11 are the others), reads as follows:
1. A surface-laminated piezoelectric-
film sound transducer, comprising:
A. a thin film of piezoelectric material having two
opposite faces,
B. two thin films of conductive
material, one of said films of
conductive material being affixed to one
of said two opposite faces and another
of said films of conductive material
being affixed to another of said two
opposite faces, thereby forming a
piezoelectric sandwich element with the
thin film of piezoelectric material in
the middle and the two thin films of
conductive material on the outside,
C. a solid, flat, substantially
inflexible substrate laminated to the
piezoelectric sandwich element along
substantially the entire surface of one
of the two conductive layers, and
2The grounds of rejection which were not repeated in the
Answer, i.e., the rejections based on D'Hoog Patent 3,941,932,
Takeuchi et al. Patent 5,210,455, Dewberry et al. Patent
4,013,992, are treated as withdrawn.
