Out of curiosity, do any of the new patent rules affect already granted patents, or do they only affect new patents?
The SHIELD ACT currently in debate in congress does not affect the patents themselves but rather the litigation over them. The loser of the litigation would be required to pay attorney fees, which is currently not the case. And since the trolls loose about 95% of the time it goes to trial they would have more at risk. Companies feel much better about pressing the issue to trial if they their fees would get reimbursed. It also requires the patent hold if they meet the troll criteria defined in the bill to put up a $50k bond prior to filing the lawsuit. This to effectively shut them out of litigating against small targets in mass.
Alas this bill will still be a few months from passing and won't affect suits already filed so their appears to be a mad rush by the trolls to get any suits filed before hand.
