I listened to this show during an out-of-town drive this morning. It is an excellent piece of journalism that digs into the business of patent trolling. The section about how the shell companies with empty offices in Marshall, Texas was particularly insightful.

One interesting thing that the show up brings up is this. Intellectual Ventures (IV) sold Lodsys the patents that they are currently using against indie mobile developers. At some point, the chief counsel for IV mentions that their usual practice is to sell the patents AND get a percentage of the royalty streams from licensees. The link between the Lodsys sales and downstream revenue for IV wasn't explicitly made, but I would bet that is the case.
