Dear PIUG list colleagues,
I have received the attached message from the provider of a weekly
commercial newsletter dealing with patent expiries, and post it to the
list for information and comment. My original document is now out of
date and I would be interested to receive details of other sources of
patent expiry information, so that eventually the document can be
updated.

I saw a note you posted to Derwent.
The link you provided
<http://www.uspto.gov/web/offices/pac/expired/index.html>
http://www.uspto.gov/web/offices/pac/expired/index.html is no longer
useful, the USPTO has closed public release of information on expired
patents. They only provide phone numbers and email address for
inquiries.
You might try www.expatent.com <http://www.expatent.com> which is a
webpage link to a fee based newsletter. I am the author of that
newsletter and although this newsletter only provides a weekly list of
expired patents, I can look up information on individual patent numbers
from my database.
