INTERDIGITAL TECHNOLOGY ANNOUNCES GERMAN PATENT OFFICE REAFFIRMATION OF ITS TDMA SYSTEM PATENT

 KING OF PRUSSIA, Pa., Oct. 20 /PRNewswire/ -- InterDigital Technology Corporation (InterDigital Technology), a subsidiary of InterDigital Communications Corporation (AMEX: IDC), announced today that the German Patent Office has confirmed the validity of InterDigital Technology's basic German Time Division Multiple Access (TDMA) system patent.
 After being granted on June 28, 1990, the German Patent was opposed by Philips Patentverwaltung Gmbh, (Alcatel) and Siemens Aktiengesellschaft in a formal adversary proceeding, called an opposition. As a result, the validity of the InterDigital Technology patent was subjected to close scrutiny by a panel of three senior German Patent Examiners with advanced technical degrees and the validity of the German Patent was confirmed by the German Patent Office. Any of the opponents may file an appeal to the German Patent Court by Nov. 19, 1993.
 InterDigital Technology said it believes that the German Patent is essential to GSM, the European digital wireless telecommunications standard. The United States counterparts of the German Patent, which InterDigital Technology believes cover TDMA and, in some instances, Code Division Multiple Access (CDMA) communications equipment, are asserted in lawsuits between InterDigital Technology as claiming patent-holder and OKI America, Ericsson, Motorola and Qualcomm as defendants and alleged infringers.
 Robert S. Bramson, president and chief executive officer of InterDigital Technology, stated, "This is very exciting news. The German Patent Office is respected as one of the most demanding Patent Offices in Europe in its standard of patentability. The fact that the German Patent has withstood a second review, without change, after opposition by three major European telecommunication companies, together with a prior approval of our basic TDMA system patent claims in an opposition proceeding filed by Nokia Cellular Systems Oy in the Finnish Patent Office, is extremely encouraging. This reinforces our judgment that our TDMA system patents are valid and increases our resolve to go forward vigorously with the American patent infringement lawsuits. InterDigital Technology is interested in granting royalty-bearing, non- exclusive licenses under its portfolio of over 450 domestic and foreign TDMA patents and patent applications. Our licensing efforts will go forward with renewed determination."
