IP-Based Location Determination Patented

little1973 writes "Digital Envoy recived patent 6,757,740 for determining, collecting and using geographic locations of Internet users. I didn't know a patent could be obtained for a simple traceroute and some lookups in a DB." The patent talks about a bit more than this (such as assigning confidence levels to bits of the looked-up information), but the long list of referenced previous patents reminds me of the saying "If you copy one person, it's plagiarism; if you copy a dozen, it's research."

First Google hit: http://www.geobytes.com/IpLocator.htm

That one has a database, but it doesn't rely on whois data, so it may not infringe the patent. Trying again...

Click on live trial and give your email. It seems almost identical to the patent - it runs a traceroute and figures out where each hop is. I have no idea how old it is, or whether it's related to Digital Envoy, though.

Can't find one at the moment, but this is definitely not new.

The priority date of the original filing is back in 1999 so you have to find prior art before that.

What, like xtraceroute?

First public release! (8-May-01998)

I traced a spammer to his exact location using the information provided in the database:

Re:Prior art - here's mine from a year+ ago ..

[xmas2003]

I've had a IP to location tool on my personal web site for over a year - it uses one of the more simpler ways of determining location (use the Perl Module Geo::IPfree ... looks like the 0.1 release for that was 2002) so does this mean that my use of that module means I'm in violation of the patent ... or is the Perl Module itself in violation?

Prior Art

[Metasquares]

There were at least two systems set up that did this beforehand: IP2Geo and Net2Geo. I did all sorts of research on this because I'm very close to releasing an application that looks up geographic information based upon IP.

There's some guy who has that link in his sig, it links to his own geo-location thingo. Where is he when you need him?

I believe you're speaking of Space cowboy. His service is located at http://hostip.info. Unfortunately it's too recent to qualify as prior art for this patent.
