The patent is from 2004. http://www.google.com/patents?id=zi8SAAAAEBAJ&printsec=a...

I hope their greed gets the best of them. Here's a poll I created to get general feedback on this subject. It's so infuriating to me, but a lot of people seem to be indifferent on the subject of patents: http://www.wepolls.com/p/3363896/

If they applied for the patent in 2001, how can they possibly sue users of wifi? 802.11 has been around longer than that.

It's possible that the patent(s) are only alleged to apply to 802.11g and/or 802.11n implementations. At least one of the patents appears to relate to MIMO, which would apply only to 802.11n.
