> You don't hear about copyright trolls as often; it's not as crippled of a system.

Strongly disagreed. Copyright is at least as broken as patents, if not more. Mickey Mouse and most of the Disney catalog should have gone out of copyright years ago but they lobbied our corrupt Congress for an insane extension which is now uniformly used throughout the industry. Our public domain has been thoroughly robbed.

For more about abuse of the copyright system and courts in general, see the history of abuse meted out by Prenda Law against various innocent parties. That shit show never should have happened, and it took courts years to stop it. Prenda attorneys are now turning state's witness against each other because they're so busted.
