Actually, with the very large donation to the Bill and Melinda Gates foundation, he's probably doing just what you recommended (albeit indirectly). The Gates Foundation has significant focus on licensing technology for use in developing countries (including pharma and other "patentable" technologies). The Gates Foundation stands to benefit from 80% of the 85% of Buffet's fortune that will be donated to charity. It's a pretty good bet that some of that money will go to taking otherwise patentable technologies and making them more accessible to the less fortunate. It might not be released to the world freely but it will be probably given to those who couldn't possibly afford the so-called "fair license feee". Good thought, though. I hope more people start thinking this way.
