In view of the lack of easy to use and free tools to download patent documents in PDF format on the web with good country coverage, Rolf Claessen of IP Newsflash and a patent attorney and partner with the patent law firm v. Kreisler Selting Werner in Cologne Germany wrote up a tool that does exactly that.
See his tool here.
Also, yesterday another reader, John Segal alerted me to another source for free PDF downloads of patents at Patent Retriever.
Thanks to both John and Rolf. I have added both to the Tools list on the left side of this blog.
