The "ROI" using the youngins was no longer there in the mid 2000's.
In 06 Dr Nunally, with his "new thinking" took care of our needs to identify infringers...rest of the story we all know.
My questions on the topic was 09 thru 12.
If anyone wants a further explaination they can contact Fred.
Just offering what I know on the subject matter...maybe that's a bad idea?
