(TCS) (NASDAQ: [ TSYS ]), a world leader in highly reliable and secure mobile communication technology, and Acacia Research Corporation (NASDAQ: [ ACTG ]), a leader in patent licensing, today announced that TCS and a subsidiary of Acacia have entered into a patent licensing alliance, whereby the Acacia subsidiary is now the exclusive licensor of TCS' inter-carrier messaging (ICM) patent portfolio.
