Appeal No. 20005-1269
Application No.09/499,060
comprising
a current generator having a first resistance, and
a circuit connected to said current generator and to said
capacitance said circuit having a second resistance and enabling a
capacitance charging current to be proportional to a square of a ratio of
the second resistance and the first resistance.
The examiner relies on the following references:
Tanigawa 4,814,724 Mar. 21, 1989
Lauffenburger 5,254,957 Oct. 19, 1993
Additionally, the examiner relies on admitted prior art (APA) depicted in
instant Figure 1.
Claims 9-20, 36, 37, and 40 stand rejected under 35 U.S.C. § 103 as
unpatentable over APA in view of Tanigawa and Lauffenburger.
Reference is made to the brief and answer for the respective positions of
appellants and the examiner.
OPINION
At the outset, we note that, in accordance with appellants’ grouping of the claims
at page 4 of the brief, all claims will stand or fall together.
It is the examiner’s position that APA discloses a capacitance and a charging
circuit connected thereto, wherein the charging circuit has a broad current source Ig1,
with no express teaching of the particular structure of the current source. The examiner
