Application No. 09/289,076
OPINION
Our opinion addresses the following groups of claims:
• claims 1, 4, and 20-24
• claim 2, 3, and 6-8
• claims 5 and 9-19.
Claims 1, 4, and 20-24
Rather than reiterate the positions of the examiner or the appellant in toto, we
address the two points of contention therebetween. First, the examiner asserts, "Meyer
(US 5652521) teaches an apparatus for monitoring leakage current (IINSULATION 14) of an
insulator 12 from a high voltage conductor 2 to ground 10 (Fig. 2,3)." (Examiner's
Answer at 10.) He adds, "primary wire 30 is arranged to carry a leakage current 32
from insulator 20 to ground 10. . . ." (Id. at 3-4.) The examiner further asserts, "Meyer
also discloses an amplifier 93 having an input connected to a secondary winding 34
constructed and arranged to produce an output signal proportional to leakage current
(Fig. 5)." (Id. at 10.) The appellant alleges, "[t]he reference does not disclose
apparatus for monitoring leakage currents from an insulator for a high voltage
conductor to ground. The reference does not disclose a primary wire constructed and
arranged to carry leakage current from an insulator to the ground, nor an amplifier
having an input connected to the secondary winding constructed and arranged to
produce an output signal proportional to the leakage current." (Appeal Br. at 4.)
