Appeal No. 1998-0440
Application No. 08/351,578
Kaminaga et al. (Kaminaga) 3 JP 5-268,032 Oct. 15, 1993
Claims 2 through 6, 8, 10, 11, and 13 through 20 stand
rejected under 35 U.S.C. § 103 as being unpatentable over
Tanizawa, Kurosawa, or Kaminaga.
Reference is made to the Examiner's Answer (Paper No. 24,
mailed June 24, 1997) for the examiner's complete reasoning in
support of the rejections, and to appellants' Brief (Paper No.
23, filed May 23, 1997) and Reply Brief (Paper No. 25, filed
July 23, 1997) for appellants' arguments thereagainst.
OPINION
We have carefully considered the claims, the applied
prior art references, and the respective positions articulated
by appellants and the examiner. As a consequence of our
review, we will reverse the obviousness rejections of claims 2
through 6, 8, 10, 11, and 13 through 20.
Claim 6 recites in pertinent part an output node
connected to a loudspeaker and an analog differential
amplifier as a driver stage. The examiner admits (Answer,
page 3) that none of the references teaches either limitation.
