Symantec is the latest target of the Trustees of Columbia University but the case is unrelated to previous lawsuits filed by the plaintiff. The new suit asserts five patents related to detecting anomalies in the operation of a computer program or executable file (7,448,084; 7,487,544; 7,913,306; 7,979,907; 8,074,115). The patents-in-suit are all owned by the Trustees and have not been previously asserted in litigation. Symantec’s antivirus and computer security software is accused of infringing the asserted patents. The complaint also refers to a letter campaign, stating that Symantec received an assertion letter in 2012. The Trustees have filed almost 20 suits, both individually and with other companies as co-plaintiff, asserting a number of patents. 12/5, Eastern District of  Virginia, 3:13cv00808
