Did you read Acacia's earnings presentation? Tell me how much of their business comes from sharing arrangements, from companies coming to them to monetize their IP, against other companies who are in violation of the law. The so-called Shield Act only does one thing - attempts to deter frivolous lawsuits. But Acacia never files frivolous lawsuits. As near as I can tell, they rarely even need to go to court and when they do, they have a tremendous track record. Can you point out a single frivolous lawsuit that Acacia has filed? Can you point out any instances where they've lost a case? If not, then what is the basis of your thesis?
That has nothing to do with Acacia - they are not a patent troll and never file frivolous lawsuits. All that does is allow patent violators, criminals in other words, to continue to get away with their abuse of the little patent owners whose IP they are stealing. Is that your position?
In addition, if I read the article right, this simply attempts to make the patent holder (that being "patent trolls" in the article I read) in a suit pay the plaintiff's legal fees if they win. Not much of a deterrent really.
