Re: IPC's on WO Doc's

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, i.e., C12N.

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.
