So, from the patent it looks like they patented TCP Keepalives which were documented in section 4.2.3.6 of RFC1122 from 1989...

http://tools.ietf.org/html/rfc1122#page-101

Edit:

Reading further, the patent is construed to cover anything IP based.

I also noted that RFC1122 is not referenced anywhere in the patent, despite extensive references to other RFCs.

Also, is it normal to have patents granted 11 years after filing in Europe? I know in the US we have changed the laws several times to discourage and eliminate submarine patents.
