About Allied Security Trust
AST (www.alliedsecuritytrust.com) is a member-owned Delaware Statutory Trust that identifies and analyzes high-technology patents being sold on the market, circulates those to its 16 member companies (each with annual revenues US $1 billion), and combines funds of interested member companies to purchase patents. It then sells the patents subject to licenses granted to those members, with proceeds returned to the members that funded the purchase. To date, it has invested US $40M to purchase 400 patents. For patent portfolios that have been sold by the Trust or are currently on the market, 82% of the money originally invested by Trust members to obtain their patent license has been returned to them at the time the patents are sold, making the Trust by far the most economical collaborative mechanism in the world for members to obtain licenses to patents that may otherwise fall into the hands of an adversarial party.
