ANNAPOLIS, Md., Dec. 11, 2014 /PRNewswire/ -- TeleCommunication Systems, Inc., today announced that it has filed a patent infringement lawsuit case against Airbus DS Communications (Airbus DS), formerly Cassidian Communications, Inc., for its violation of five patents in TCS' 54-patent, public safety technology portfolio.

The TCS patents that are allegedly infringed by Airbus DS's products include:


    --  U.S. Patent No. 8,681,946 - "Mobile Automatic Location Identification

        Airbus DS's Vesta/Sentinel 4 NG911product
    --  U.S. Patent No. 7,903,791 - "Enhanced E911 Location Information using
        Voice Over Internet Protocol (VoIP)"; one or more claims alleged against
        Airbus DS's Sentinel ESC1000 Controller product
    --  U.S. Patent No.: 8,149,997 - "Protocol Converting 9-1-1 Emergency
        Messaging Center"; one or more claims alleged against Airbus DS's

News Facts:


    --  TCS leads the nation on ESInet deployments and is the premier provider
        of NG9-1-1 software and end-to-end solutions. Offerings include NENA i3
        standards-compliant call-routing and call-handling systems.
    --  In 2006, TCS became the first company to deliver NG9-1-1 calls, and the
        company has since delivered more NENA i3 9-1-1 traffic than all other
        manufacturers combined. TCS completed the nation's first successful
        cellular 9-1-1 call more than fifteen years ago and now deploys cellular
        and Voice over IP (VoIP) 9-1-1 service to operators nationwide,
        supporting half of all wireless and VoIP Enhanced 9-1-1 (E9-1-1) calls.
    --  TCS prevailed in a patent dispute filed by Cassidian Communications
        against TCS and its wholly owned subsidiary microDATA GIS, Inc.
        (2:12-cv-00162-JRG) in December 2013 when an Eastern District of Texas
        jury returned a verdict that all asserted claims of the Cassidian
        Communications patent were invalid and not infringed. Cassidian
        Communications has continued to file motions and an appeal in an attempt
        to overturn the trial court's verdict.

TCS Chairman, CEO and President Maurice B. Tose stated: "TCS is a company founded on continuous innovation. We are steadfast in our commitment to developing innovative new products as evidenced by our growing patent portfolio and expanding products. As a leader in public safety technology, the emergency communications solutions we develop and the correlating intellectual property rights are essential to TCS' future. In addition to our dedication to the advancement of the nation's emergency communications infrastructure, we must uphold our commitment to our customers, partners, and shareholders in the protection of these innovations from companies, such as Airbus DS, who defiantly disregard TCS' intellectual property rights."
