with its subsidiary InterDigital Technology Corporation (ITC), today announced a
settlement ending the companies' long-standing patent infringement
litigation.Under the settlement agreement, the companies have entered into a
non-exclusive, worldwide, royalty-bearing license agreement covering all of
ITC's patents for GSM, TDMA (D-AMPS), GPRS, EDGE and PDC.

Additionally, all claims asserted in the patent infringement litigation are
