AMD Patents
Posted By Van Smith

Date: October 14, 2001

Michael Westman has been conducting research into AMDs patent portfolio.  In the last few years AMD has been one of the most successful patent producing companies in the world.  Despite the great size disparity, the number two CPU company is outperforming its much, much larger rival, Intel. 

Introducing his research, Michael stated, I took a look at the patents presented at www.chip-architect.com and found some more patents. I marked the most interesting with bold text, but there is a lot of nice stuff here.
