P
art
s

of the scheme
in Annex 6, i.e., subgroups under main groups H02P

7/00,
H02P 23/00, H02P 25/00, H02P 27/00 and H02P 29/00,
w
ere

approved

with some modifications

(see

the Technical Annex
es

below).

The Rapporteur was invited to revise and align the notes in the four main groups
,

and to clarify:

o

whether the new groups H02P 23/20 and 23/22 would exhaust the file scope of their one
-
dot
parent group H02P 23/18;

o

the title an
d scope of group H02P 23/34
,

in particular the meaning of the term “controlled”;

o

the intended scope of group H02P 23/36 since the techniques indicated as examples are
applicable also to the preceding subgroups of main group H02P 23/00;

o

whether there is a
need for a precedence reference in group H02P 25/032 to 25/034 or
whether 25/034 is a subgroup of 25/032
, and the relationship among groups H02P

25/032,
H02P 25/034 and H02P 25/06; and

o

the intended scope of groups H02P 29/20 and H02P 29/62.

The EPO was in
vited to provide an
Revision Concordance List (RCL)

and the I
nternational Bureau

to provide a
List of Cross References (CRL)
.

Germany was invited to submit an initial proposal concerning proposed amedmends in
group

H02P

9/00 under project WG

020 to be cons
idered by the IPC Committee of Experts at its
forty
-
fifth session.

Le rapporteur a été invité à réviser et harmoniser les notes dans les quatre

groupes principaux,
et à
établir clairement

:

o

si les nouveaux groupes

23/20 et 23/22 ép

groupe parent à un point

23/18;

o

l’intitulé et la portée du groupe

H02P

23/34, en particulier le sens du terme “controlled”;

o

la portée prévue du groupe

H02P

23/36 puisque les techniques indiquées à titre d’exempl
e
sont également applicables aux sous
-
groupes précédents du groupe principal H02P

23/00;

o

s’il est nécessaire de prévoir un renvoi de priorité dans le groupe

H02P

si 25/034 est un sous
