Wi-Fi Redirect Gateway Patent for Hotspots

Glenn Fleishman writes "Over at WiFiNetNews.com, we just broke the story that Nomadix was issued a patent covering hotspot gateway page redirection. Nomadix makes hardware and software for the hotspot industry, and this patent would cover redirection used by community networking portals (like NoCat), sponsored free networks (like NewburyOpen.Net), and fee networks (like Wayport, T-Mobile HotSpot, and Cometa). It's unclear what terms Nomadix wants for a license, but this patent seems to take a standard way of doing business and put it under fee -- although Nomadix may have been the first firm to employ this method for proxy URL redirection."

It seems this patent is rather broken...

The obvious workaround is to simply not redirect. Install a transparent proxy and serve up your desired page on the first request. This defeats

"modifying, at the gateway device, the original destination address access request and communicating the modified request to a redirection server if redirection is required;"

Better yet, claim 1 is fatally flawed. It includes the words "storing the original destination address if redirection is required". Claim 6 is likewise flawed: "stores the original destination address request if redirection is required". So the really obvious and easiest solution is to do exactly what you've been doing, except that you don't store where the user was trying to go, and they have to type the URL or back up and hit the link again.

While this was a valiant attempt by Nomadix to patent a process that was in common usage (my university used something with this effect, though not necessarially this process when I first hooked up on its dorm network the second half of my sophomore year, in '98), it ultimately falls short of the goal, and Nomadix should fire whatever patent attourney they had file this one.
