Deals made (http://www.theinquirer.net/?article=17445) between id Software (http://www.idsoftware.com/) and Creative Technology (http://www.creative.com/) seem to be not too happy a place. Read on for why...

"Creative apparently has a patent on a shadowing technique that appears to have some similiarity with id Software's soon-to-be-available DOOM3's shadowing technique" - Beyond 3D (http://www.beyond3d.com/forum/viewtopic.php?topic=14459&forum=9).

"Carmack [says] the patent situation well and truly sucks." - The Inquirer (http://www.theinquirer.net/?article=17500).
