I meant to send this to the list, but sent it to Jan only.

I forgot to mention a particularity of the espacenet database. you can never be sure a patent is granted. If you see the suffix B1 when looking at a patent pdf then it was granted but if you see the A1, A2 or A3 you only know it was applied for, it might be granted or it might not. See details at http://www.aful.org/wws/arc/patents/2000-10/msg00272.html
