Bah!
The attitude to patent farming should be the same as that held toward cybersquatting: If you have no real intended use beyond extortion, you should be forced to sell on in a certain period of time.
Personally, I reckon patents in this sort of position should expire into the public domain after a short period - say five years. That way there is still value in them to be had but not the incentive to the rapacious goings-on of late.
But of course, I am naive. Patent-farming is the new black. Wall Street has shown us the way - make nothing of value, merely suck vampirically on the effort of others, printing virtual money out of thin air. Watch out for arising circular references in the system which can bring it down around your ears, but if they happen don't worry, the government will bail everyone out of their manifest incompetence with no questions asked.
Alas poor Kodak. Doomed to the buggy-whip oubliette before they knew it was coming. End of an era.
