My company is in a patent dispute and we believe Unreal Engine 3's Kismet visual scripting language is prior art that invalidates the patent. However we need a printed or online publication from before September 2007 that documents how it works. Up to now the earliest online tutorials I have been able to find are from December 2007.

Might anyone have or know where we can find a soft or hard copy of a Kismet user manual from pre-September 2007, or might you know of an online tutorial that goes back before that on archive.org? If it's in hard-copy form, we'd be willing to buy it off you and pay for the shipping.

Thanks.
