May 27, 2011- PTO assignment records indicate that Mosaid has acquired a portfolio of content delivery networking patents from Allied Security Trust (AST).  The portfolio was marketed during 2010 on behalf of AST by two different brokers.  Sales efforts by the first broker were halted when Limelight Networks filed a complaint for declaratory judgment against AST after receiving marketing materials Limelight believed constituted an accusation of infringement.  The patents assigned to Mosaid by Twister Investments, LLC  include four that were the subject of litigation against Akamai, Novell, Volera, Cache Flow, and Inktomi in 2001.
