Marathon Patent Group subsidiary CRFD Research filed its first suits this week in against Akamai, AT&T, Cablevision, Comcast, Cox Communications, DirecTV, Dish Network, Level 3 Communications, Limelight Network, and Time Warner Cable. Defendants’ media streaming services are the accused products in each case but the filings can be divided into two groups, each one involving a different patent. Three of the cases, involving Akamai, Level 3, and Limelight, assert a patent related to rendering and formatting web page content on a mobile device (7,574,486). The remaining seven litigations assert a patent related to redirecting streaming media content from one device to another (7,191,233). CRFD acquired both patents from TeleCommunication Systems in September 2013. RPX reviewed the patents-in-suit as part of an open market opportunity in 2012 and again in 2013 . 1/17, District of Delaware, 1:14cv00058, 1:14cv00059, 1:14cv00060, 1:14cv00061, 1:14cv00062, 1:14cv00063, 1:14cv00064, 1:14cv00065, 1:14cv00066, 1:14cv00067,
