RE: US Application Numbers

Heather,
I think your assumption is incorrect. When the application series change
over, they start with 1 and continue to 999,999 without regard to previous
applications that had the same number in earlier series. I think you're
giving the USPTO receiving office too much credit. When an application comes
in, they give it the next available number.

Your attempts to locate info on US applications obtained from overseas
publications are likely to be futile. The USPTO will not release an
application or file history unless the application is listed on the front
page of a US patent publication. In the case of an applicant who filed in
the EP or PCT (for example), with a US priority application, but has no US
publication from that application (grant or pre-grant), there is no way
(that I know of) to determine the fate of the US application (abandonment,
rejection, delayed examination, etc.).

Subject: US Application Numbers

Hello All,

Does anyone know whether or not a serial number in a US application can be
reused when the series changes if the same number in the previous series is
still pending?

For example: an application was assigned 123,456 in 1990 and has not
granted. Another completely different application is assigned 123,456 in
1995, and subsequently granted as a patent in 1999. Does that mean the 1990
application was abandoned, or was the number simply re-used because the
series changed from 08 to 09?

I'm hoping this will be a way to determine the status of those mysterious US
applications we see as priority documents in patent families and can't find
anything about. If not, does anyone know a way to find out if a US
application went abandoned if there's no US children? The application I'm
interested in is the priority of an EP. The INPADOC record doesn't say
anything about the US priority lapsing.

Thank you!
