Deconstructing Pro-Patent Troll Arguments

Techdirt has a good deconstruction of some of the more mischievous arguments in favor of patent trolls — litigious sorts who collect patents and use them as clubs:

The success of a product usually doesn’t have very much to do with the inventions, but the innovation of how it was brought to market.
That is, the actual invention, by itself, is pretty worthless. It’s the
embodiment of the idea in a way that satisfies market demand that makes
it worthwhile.
