Thanks, Jim. For future reference. FOR IMMEDIATE RELEASE November 18, 1996 INTERDIGITAL'S PATENT UPHELD IN GERMANY King of Prussia, PA, November 18, 1996 . . . InterDigital Communications Corporation (ASE: IDC) (http://www.interdigital.com) announced today that the German Federal Patent Court upheld the validity of InterDigital Technology Corporation's German Patent No. DE 3609395 related to wireless digital radio communications systems employing Time Division Multiple Access (TDMA) technology. The basic German system patent was granted by the German Patent Office in 1991 and, thereafter, was opposed by Standard Elektrik Lorenz (Alcatel), Siemens Aktiengesellschaft (which later withdrew), and Philips Patentverwaltung Gmbh. The German Patent Office had then upheld the validity of the patent and the opposers commenced the present appeal to the German Federal Patent Court. During the appeal, InterDigital, as part of its strategy of continuing to refine its patent claims, divided out all of the claims in the patent except Claim 1 for further prosecution before the German Patent Office. The German Federal Patent Court upheld a version of Claim 1, based on changes proposed by InterDigital addressing frame timing and slot length variation. InterDigital's Chairman, Harry Campagna, was delighted with the decision, stating that 'the decision further strengthens our belief that the Company has a strong patent portfolio relating to the digital TDMA wireless communications technologies being employed worldwide.' Mr. Campagna said that 'the decision was particularly pleasing in that the patent at issue was the foreign counterpart to the U.S. Patent No. 4,675,863 that a lay jury had found invalid in a U.S. lawsuit brought by Motorola.' In a June 17, 1996 decision - which ITC has appealed to the Federal Circuit Court of Appeals - the Federal Trial Judge upheld the verdict as it related to the '863 patent. The decision of the German Federal patent Court - which is comprised of judges with significant technical expertise and is highly regarded throughout Europe - enhances the Company's belief that the U.S. lay jury failed to understand the highly technical issues involved with the patent. InterDigital develops and markets advanced wireless telecommunications systems using proprietary digital technologies for voice and data communications. Over 275 of its UltraPhone© TDMA systems have been sold worldwide. InterDigital, in conjunction with Siemens AG and Samsung Electronics Co., Ltd. is developing Broadband Code Division Multiple Access? (B-CDMA) technology for use in future wireless systems and products. InterDigital Technology Corporation (ITC), a subsidiary of InterDigital, holds and is the licensor of an extensive patent portfolio on TDMA and B-CDMA technologies

Will providers ever use channels wider than 10Mhz? The Mobile Communications handbook, Second Edition, 1999, IEEE Press Channel bandwidth WCDMA: 5,10,20 MHz cdma2000: 1.2.5,5,10,15,20 MHz I dont think you really answered the question. There is very little doubt that 3G standards will have provisions for channel bandwidths beyond 5MHz.....the key question is weather these will ever actually be implemented. As of right now....No operator that I have seen has even considered using a system with channel widths beyond 5MHz. If you have seen any, I would love to see a reference. Are you are saying that IDC would be owed patents on implementations of 3G that use less than 10MHz, just because the standard as a whole allows for larger channels? Slacker
