Top Secret!
An inventor who approached the U.S. Army with an idea for a "mysterious acoustic wave propagation machine" has been barred by the Army from even talking about the invention, much less filing a patent application on it. And that inventor, Bruce Horton, has now filed a lawsuit against the Army in a California federal court - accusing the Army of having his patent application "illegally frozen and not reviewed nor allowed by the United States Patent and Trademark Office."
