Shared Memory Graphics LLC is a small firm based in Newport Beach, California that designs microprocessors. The company has two patents that describe how microprocessors have the ability to fine-tune the graphics by balancing a flow of data from different sources. Now they are using these patents to file an infringement lawsuit against Apple over the iPod and iPod Touch, Nintendo over the Wii controller, and Sony for their PSP and PS2 consoles.
The patents originally belonged to Alliance Semiconductor Corporation. Alliance started in 1985 and had 144 employees with millions in revenue at one point, but eventually became a holding company in 2005. Alliance ended up selling the patents to Shared Memory. The lawsuit was filed at the U.S. District Court in Arkansas and Shared Memory is demanding monteray damages.
