ANNAPOLIS, MD--(Marketwire - February 25, 2011) - TeleCommunication Systems, Inc. (TCS) (
TCS patent '748 describes a system, method, and apparatus that allow a wireless subscriber to send a digital packet to a user on a different wireless carrier by addressing the packet with only a phone number.

"We are pleased that the reexamination of patent '748 has reached a successful conclusion and that the validity of our patent claims has been affirmed."
