conductor passing through the opening” [brief, page 9]. The
examiner responds that the schematic representation of current
transformer 30 in Lehrmann is understood to indicate that
current-carrying conductor L3 passes through an opening formed
by the windings of the current transformer [answer, page 9].
Appellant responds that there is no current sensing or hole
window in Lehrmann comparable to the detection window 16 as
disclosed [reply brief, pages 5-6]. The examiner also notes
that the monitoring circuitry of Lehrmann can be considered to
be a box having an opening 30 for receiving the current-
carrying conductor L3 [answer, page 10]. We find ourselves in
agreement with the examiner on both points.
First, we agree that the schematic representation of
current transformer 30 in Lehrmann was known to the artisan to
represent the windings of a coil surrounding the conductor L3.
As the examiner has pointed out, the coil was known to have an
[axial] opening through which the current-carrying conductor
[L3] passes. This arrangement is sufficient to meet the broad
language of claim 5. Even though appellant argues that
Lehrmann itself does not explicitly show the claimed opening,
