RE: [PIUG List] U.S. application number format

Stephen,

In fact your example goes further than Alan's original assumption. Alan
suggested that no information would be lost when writing US application
numbers are written as 8 digit numbers. Your example shows that the
current Espacenet (and Inpadoc) approach of replacing the series number
by an application year can create unclarity concerning the true priority
where the (complete) source data is absolutely clear.

Dear Alan
Although it will not take into account the finer details of the scheme
as given by Carl Oppedahl, you may find the following list helpful:
<http://www.uspto.gov/web/offices/ac/ido/oeip/taf/filingyr.htm>
This provides a concordance table such that, given a filing year, it is
possible to derive the series code. It shows that some series commenced

at a point in time which did not coincide with the end of the calendar
year. The one year to watch out for is 2003, when the regular filing
series 10
grew from approx. 350,000 to 750,000 at the same time as the provisional

application series 60 increased from 437,000 to 532,000. I have
examples where a PCT filing based on a series 60 priority from 2003 was
erroneously put into the same family with other cases claiming priority
from the series 10 application with the same number and year. Clearly,
in this particular case, combining a year with a serial number leads to
an ambiguous result.
