“I am privileged to assume this role at such an exciting time for InterDigital and the wireless industry,” said Mr. Clontz. “As wireless services become more pervasive, the technical challenges to meet consumer demands, particularly for higher throughput of wireless data, will become even greater. Solving such challenges is InterDigital’s core strength.
