Comments following invitation in Annex of project file


EPO thanks the Rapporteur f
or his efforts regarding the definition project of H04M.


With regard to the request by the Rapporteur, EPO likes to comment on the present
proposal taking into account the
previous

comments:



1.


VoIP: multi
-
aspect classification is proposed.


1.1


EP
O appreciates the concern of the JPO with regard to the passage “With
regard to VoIP ...” in the passage "Relationship between large subject matter areas".
The present wording might indeed mislead the IPC user to believe that VoIP is
exclusively classified

in H04L.




Our specialists noted that, in the field of VoIP, several offices appear to
allocate systematically H04M in combination with H04L

(see e.g. certain family
members of EP1672900, EP0928095, EP0938225, EP1566984).




The EPO is following a simila
r approach, which was meant by the
passage
(Annex 11)

“When VoIP is used to emulate or simulate PSTN/ISDN services,
the service, as presented to the user, is still classified in H04M”.




In that respect, the comment of the DPMA is appreciated which believ
es that
a general distinction between lower transport
-
related functions and
service/application
-
related functions is widely accepted and seems feasible.


1.2


Therefore a multi
-
aspect classification
, as
explicitly foreseen in IPC 8
,

is
proposed whereby Vo
IP is classified in H04L in combination with H04M if the
"subject
-
matter" to be classified is specifically applicable to voice services. The
precise wording is open to discussion. A proposal is given here below:

With regard to VoIP, transport
-
related aspec
ts (constituting layers 1 through
3 of the OSI 7
-
layer Basic Reference Model) of VoIP are classified in H04L.
Voice service
-
related functions above OSI layer 3 and/or the Internet
Protocol Layer are also classified in H04M.



1.3


EPO suggests that a simila
r text is inserted in the IPC scheme.

I
f
such a
multi
-
aspect classification

would be
ex
c
epted
,

Rapporteur

should

be invited to

promote
an IPC
revision project
to amend the

scheme
.



2.



SPIT
,

SPAM


2.1


I
n the present proposal (Annex 18
), SPIT and SPAM p
revention are explicitly
excluded from H04M1/00 (passage "References relevant to classification in this
group
-

This group does not cover: ...). The JPO (Annex 14) however mentions that
the references should be moved to the "Definition statement" which usu
ally
mentioned what is covered. Consequently, there seems to be a misunderstanding.

Actually Annex 18 is contradictory in itself.


2.2


View of EPO experts






Most of SPIT is related to the Session Initiation Protocol SIP which is
considered to be media
neutral. In that respect it might not be appropriate to classify
such documents exclusively in H04M.




At present,
SPIT is mainly classified in the groups H04L29/06
M
2S3S
(previously H04L29/06C2)

(SIP protocol
-
based), H04L12/58F (strong link to SPAM)
and H
04M3/436 in combination with H04M7/00M (similar to call screening)
(Further
support for non
-
telephonic, i.e. non H04M, aspects of SPIT can be found under
http://en.wikipedia.org/wiki/VoIP_spam
.
).




As

such, at EPO, SPIT is not classified in H04M1/663 as proposed.

Therefore, i
n view of the above
EPO is reluctant to support such a proposal
.



3.



CTI





As far as understood it appears controversial as to where to classify
Computer Telephony Integrati
on CTI in H04M. However, it seems undisputed that
H04M is the right place for CTI. It is therefore proposed to at least mention CTI in the
"Definition statement" of H04M.






4.



Defin
i
tion statements
in general


4.1


As a more general remark, EPO notes
that in several places (e.g. H0
4
M
3
/00,
H0
4
M
5
/00
, H0
4
M7/00
) the contents of the definition statement is empty. EPO is
convinced that at least a minimum of information, beyond the mere repetition of the
group titles, should be provided at these places, to en
hance the unders
tanding of the
subjects covered, since

the group titles are not considered as completely self
explanatory.


4.2


Furthermore
,
i
t is believed that the classification statements provided so far
seem to avoid words and phrases which can be fou
nd in classified documents
contrary to the purpose of classification definitions.

In this respect, for example, it remains unclear if an “Automatic exchange” in the
sense of H04M3/00 is limited to circuit
-
switches or also comprise softswitches and
IMS ser
vers such as Call State Control Functions.

Therefore, the EPO recommends rapporteur to quote the following acronyms e.g. like
PSTN, ISDN, ISUP, SIP, H.323, gatekeeper, call agent, IP multimedia system,
softswitch.

5.2


H04M3/00




Definition statement


This subclass covers:


Telephone exchanges or telephone switches and in particular digital switches
which work by connecting two or more digital circuits together, according to a
dialed telephone number. T
his subclass covers as well switches of the Public
Switched Telephone Network PSTN as well as Private Branch Exchanges.


Supplementary services provided by a telephone switch or a network of
telephone switches.


Voice service provided by networks comprisi
ng s
oftwitches, call agents,
call controller, call state control functions

are also classified here.

In addition to the telephone switches this subclass also covers application
servers for information services, call distribution and queueing services,
mes
saging services and conference services.


Arrangements for providing information services which are also referred to as
Interactive Voice Response Systems, Voice Portals or Voice Browsers.


Centralised arrangements for answering requiring operator interven
tion are
also referred to a
call centres

and usually employ call queueing and call
distribution.


Centralised arrangements for recording messages for absent or busy
subscribers which are also referred to as
Voice Mail Systems
.


Arrangements for connecting
several subscribers to a common circuit which
are also referred to as
conference

bridge.
