Circuit arrangements or
systems for wireless supply
or distribution of electric
power
H02J 17/00 now covers any form of
contactless transmission of electrical
energy, including capacitive
transmission -
Note(s)
a note remark referring to this might
be helpful
1. In this group, multiaspect classification is
applied, so that subject
matter characterised by
aspects covered by more
than one of its subgroups
should be classified in
each of those subgroups.
2. When classifying in this
group, the specific
technology used for the
wireless power
transmission is classified
in the relevant group of
H02J 17/05 - H02J 17/30,
while arrangements or
functional aspects are
classified in groups
H02J 17/40 - H02J 17/90.

We can’t support this subgroup,

characterised by the
arrangement of the
transmitting antennas, e.g.
directional array antennas
or Yagi antennas
We can’t support this subgroup,
because specific embodiments of the
transmitting antennas include not
only classical Yagi antennas but also
coils or inductors or laser diodes,
other light transmitters or capacitive
transmitters.
If the application is focused on the
design of the transmitter, a
classification into the appropriate
IPC for the transmitters is
meaningful, for example, antennas
into H01Q coils/inductors to H01F,
capacity into H01G, laser diodes into
H01S or other light
emitter/transceiver into H04B

characterised by the
arrangement of the
receiving antennas, e.g.
rectennas
We can’t support this subgroup,
because specific embodiments of the
receiving antennas include not only
classical Yagi antennas but also coils
or inductors, light receivers or
capacitive receivers.
If the application is focused on the
design of the receiving element, a
classification into the appropriate IPC
for the receiving element is
meaningful, for example, antennas
into H01Q coils/inductors into H01F,
capacity into H01G, light

responsive to the presence
of foreign objects, e.g.
detection of foreign objects
DE comments
We can’t support this subgroup,
because object detection is a
completely different technology as
the supply and distribution of electric
power.
If the application is focused on the
development of the foreign body
detection, a classification into the
appropriate IPC for detection
methods is meaningful, for example,
electric or magnetic
detection/tracking into G01V 3/.. or
optical detection into G01V 8/.. or
image /pattern recognition into G06K
9/.. or to camera systems or to
evaluation of temperature changes
N H02J 17/70 ·
involving the reduction of
leakage electric, magnetic
or electromagnetic fields
We can’t support this subgroup,
because it relates to the configuration
of the respective transmission
element to improve the management
of the field, e.g. Cores/magnetic
shields in transmitting/receiving
coils/antennas; see H01F 27/ and
also the remarks on H02J 17/23
N H02J 17/80 ·
involving the exchange of
data concerning supply or
distribution of electric power
We can’t support this subgroup
and data exchange aspects shouldn’t
be classified into H02J 17/, since
data transfer methods (modulation /
demodulation) are covered by other
relevant IPC groups

involving position detection,
alignment or optimisation
DE comments
In our opinion, this group should
cover subject matter regarding the
adjustment, balancing or alignment of
the resonance of the coils to
compensate their misalignment and
to increase the energy transfer.
This group should not cover the
position detection or the movement of
the coils to each other; H02J 7/..
covers for instance the movement of
the primary coil.
Therefore we suggest to change the
wording of the group title, which
could be somewhat like:
“involving resonance alignment or
optimization without changing the
position or moving the coils”
When the application is focused, for
example, on the positioning of
vehicles for contactless energy
transfer, then it should not be part of
H02J 17/00, it should be classified
according to G05D.
