It is my impression that quality IPC's are assigned if an
International Search is done, i.e., the A1 documents. It is more
likely that the A2's have unusual or minimal IPC's. I have often
noted WO A2's with only a subclass assigned, for example, C12N as the
only IPC assigned. This is not a complete IPC code. I don't know who
assigns IPC's on PCT documents if no IS was performed, but I would
guess that the receiving authority does it.

Judith, the patent offices themselves supply the data, with all
its
gaps, problems and delays.
I'd agree with the comment that the IPCs can be strange -- and
with
someone else's comment that the PCT sometimes doesn't classify
abstracts, putting them at the beginning of each week's
sequence. I
don't know of another authority that does that. Presumably the
PCTs on
disc are the same and it's only when they enter a national stage
that
anyone else thinks of giving them an IPC (e.g. when an EP number
is
assigned).

In response to Stu's letter on Japanese B2 documents - I understand
that EDOC (Questel) also tracks Japanese patent status but I do not
know if it depends on the same information that is sent to INAPDOC -
does anyone know?
INPADOC seems to get sporadic information. I wanted to know
how many patents were assigned to a certain company in INDIA and
found only a few listed in INPADOC. A patent agent found in India
found many more. Who is responsible for supplying the patent
information from each country to INPADOC?
I am dismayed as everyone else about the removal of the
drawings and abstracts from the PCT Gazette and having it online
would be a good substitute only if the structures were provided.
Also, sometimes I find relevant patents in the oddest sections in
the Gazette - with an assigned IC that I would not have expected. So
that means I might miss something when I run a search on the CD by IC
codes.
