The third way is through the European Patent Office (Espacenet). I have 
found very useful the simplified Advanced Search page of the British site:
http://gb.espacenet.com/search97cgi/s97_cgi.exe?Action=FormGen&Template=gb/e 
n/advanced.hts (text of the link all in a line).
In particular, look to the IMPADOC family of a patent to discover all his 
international history.
You can download the patenss in pdf format.
