I have noticed that China is fairly liberal in giving out patents to U.S. companies or maybe rather individuals. For instance, a friend in Fla got a patent there for one or another thing with his company called Magne Tronix. If you would be interested in a good read on business start ups and a really great invention he was cultivating with an inventor on how to convert nuclear waste to electricity, check up his book. Phil Talbert. book title is "The half life of a nuclear battery" published about 2009 can be found on amazon. As a side note, were you aware there is a lot of nuclear waste buried in San Francisco Bay and also I think in other places....
