element and is performed by a diode. More importantly,
Sieverin does disclose a temperature sensitive resistor R but
T,
it is connected to the amplifier offset terminals and not to
the output of the amplifier as required by claim 1.
Similarly, with regard to Kostal, Figure 1 does show a Hall
element 4 and amplifiers but we find no temperature sensitive
resistor within a temperature compensation circuit wherein the
temperature compensation circuit is connected to the output of
an amplification circuit in such a manner which prevents
changes in the output signal from the Hall element from
affecting a voltage potential across a temperature sensitive
resistor, as claimed. The examiner identifies resistors R1,
R2 and R3 in Kostal as the claimed “temperature sensitive
resistor” but we agree with appellant that these resistors in
Kostal appear to have no relation whatsoever to the output of
the Hall element.
Accordingly, the rejections of claim 1 under 35 U.S.C.
§ 102(b) are reversed.
The examiner also rejects claim 1 under 35 U.S.C. § 103
based on APA and Mount. However, Mount is not directed to a
