Franco De Bonis, audio sales marketing manager at Creative Labs Ireland, told the INQUIRER: " In our earlier graphics years (1999) we developed a technique for shadowing that is optimized. Recently "id" approached us informing us that they had used this technique in the development of DoomIII and had subsequently discovered that we owned the patent on it.
" Like any company Creative owns a number of technology patents and like any company we need to ensure that our patents are protected. Simply allowing another company to knowingly use a patent you own weakens your position and future claims against infringement. We therefore had to find a legally acceptable way to allow id to use this technique without it being seen as an infringement. The goal was the same from id's perspective".
