It's great that the trolls would have to pay for losing the lawsuit, but the basic problem remains - the company being sued can't afford to be the losing party, leading it to pony up outrageous settlement/royalty fees. Even for junk patents, certain well known jurisdictions (read: Marshall, TX) award the trolls in these cases 80%+ success rates at trial. The trolls would only be on the hook for the remaining 20%, in addition to having collected all the settlements and royalties for cases which never made it to trial. In view of the above I don't see this changing much of anything.
