Is it just me or does this smell like the Nintendo vs. Ampex case from the 80's?
The N. v. A case was over Ampex's '555 Patent' that allowed bit mapping handled through the system's memory directly instead of a frame buffer.
The Atari 2600 used this method. The NES, however, did not. It had a dedicated frame buffer for the video chip, as opposed to sharing memory devoted to the system.
Here's the scary part: The judge at the time was not experienced with patents.
Nintendo lost the case miserably. Fortunately, they applealed, and they were awarded 500 million in damages, one of the largest awards for a patent infringement lawsuit in U.S. history.
Needless to say, it ran Ampex out of business.
Let's hope XFire wins.
