INTERDIGITAL STIPULATES CERTAIN OF ITS CDMA PATENTS ARE NOT NECESSARY TO THE INDUSTRY STANDARD

 SAN DIEGO, Sept. 17 /PRNewswire/ -- QUALCOMM Inc. (NASDAQ: QCOM) announced today that it has reached agreement with InterDigital Communications Corp., InterDigital Patents Corp., and InterDigital Technology Corp. (InterDigital) to confirm that InterDigital does not contend that equipment and systems built in compliance with Telecommunications Industry Association interim standard IS-95 infringe two InterDigital patents. Under the terms of a joint stipulation filed in San Diego federal court, InterDigital confirmed that it does not believe, or contend, that United States Patent No. 5,081,643 and/or No. 5,093,840 would necessarily be infringed by apparatuses, methods, systems and technology compliant with or predicated upon the disclosures of the Telecommunications Industry Association interim standard IS-95, entitled "Mobile Stations-Base Stations Compatibility Standard For Dual- Mode Wideband Spread Spectrum Cellular System (IS-95)," as presently drafted.
 This stipulation was reached in a suit for declaratory relief filed by QUALCOMM to confirm that its Code Division Multiple Access (CDMA) technology would not infringe these two patents. Under the stipulation, unless InterDigital provides advance notice to QUALCOMM and its licensees of its intention to assert these two patents, InterDigital is precluded for three years from instituting litigation against QUALCOMM or any of QUALCOMM's licensees for infringement of these patents. Additionally, InterDigital Communications Corp. has agreed that any future litigation over these patents is subject to personal jurisdiction and venue in the San Diego federal district court.
 This stipulation does not affect the two remaining actions pending between QUALCOMM and InterDigital. In a lawsuit pending in federal court in Philadelphia, InterDigital Technology Corp. contends that equipment built in compliance to IS-95 infringes three of its patents (the '571, the '056 and the '375). QUALCOMM denies these allegations and continues to defend against InterDigital's claims. In an action filed in San Diego federal court, QUALCOMM contends that InterDigital Communications Corp. is liable for infringement of QUALCOMM's '307 patent.
 QUALCOMM develops, manufactures, markets, licenses and operates advanced communications systems and products based on digital wireless technology. QUALCOMM's products include the OmniTRACS(R) satellite communications system, digital wireless telephone systems and products based on CDMA technology. The company also develops and markets a range of VLSI devices.
