CALGARY, AB, December 17, 2003 – Zi Corporation (Nasdaq: ZICA) (TSX: ZIC), a leading provider of intelligent interface solutions, today announced it has licensed its user-friendly eZiText® predictive text input technology to Taiwan-based Ambit Microsystems Corporation, a global leader in the production of networking and telecommunications components.
