CIRRUS LOGIC PATENTS
I wrote and/or prosecuted a number of VGA and Graphics
Patents for Cirrus Logic, Inc. When Cirrus
got out of the Graphics business, many of these Patents were sold to S3,
Inc. Some have been or are being
litigated. I also have written a number
of Patents for Cirrus Logic on disc controllers, A/D converters and other
software, hardware, and firmware inventions.
This list is by no means complete.
