TeleCommunication Systems, Inc. Defeats Infringement Claim by Cassidian Communications, Inc. in Texas Case

Note: Comtech Acquired TCS on 2/23/2016

ANNAPOLIS, Md., Dec. 20,  2013 /PRNewswire/ -- TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in highly reliable and secure mobile communication technology, today announced that TCS has prevailed in a patent dispute filed by Cassidian Communications, Inc. (Cassidian) against TCS and its wholly owned subsidiary microDATA GIS, Inc. (2:12-cv-00162-JRG). On December 20, 2013, an Eastern District of Texas jury returned a verdict in favor of TCS and microDATA. All asserted claims were found to be not infringed and invalid. Cassidian originally filed the lawsuit against microDATA on March 26, 2012 asserting US Patent 6,744,858 prior to TCS' July 2012 purchase of microDATA. TCS was named as a defendant after the acquisition.

Cassidian had asserted the patent against a number of companies providing technology in the 9-1-1 public safety market. While other companies settled with Cassidian, TCS took the case to trial after the company's attempts to mediate the dispute were unsuccessful.
