According to a report in eFluxMedia and the Wall Street Journal, several large tech companies have formed an organization called the “Allied Security Trust” to purchase patents for technologies that members of the trust are planning on using.  This is just another way many of America’s largest tech companies are fighting back against patent trolls.   The “Allied Security Trust” is only for companies that can afford it steep membership fee - $250,000 to join and a $5 million dollar deposit!
