SAN DIEGO, March 23 /PRNewswire/ -- QUALCOMM Incorporated (NASDAQ:QCOM) today announced that the validity of one of its key Code Division Multiple Access (CDMA) patents has been reaffirmed. QUALCOMM has received notice that the United States Patent and Trademark Office will issue a Reexamination Certificate confirming the patentability of all 49 claims of U.S. Patent 5,103,459 with minor amendments and allowing 19 additional claims. The patent, which was issued in April 1992, had been the subject of two requests for reexamination filed by anonymous requestors in 1996 and 1997. The requests for reexamination alleged that prior publications not originally considered by the Patent Office rendered the patent invalid. In total, more than 80 additional references were submitted to the Patent Office during the reexamination proceedings by the requestors and QUALCOMM. The Patent Office, after carefully reviewing all the additional prior art, concluded that the patent was valid and that QUALCOMM was also entitled to 19 new claims. The '459 Patent, entitled "System and Method for Generating Signal Waveforms in a CDMA Cellular Telephone System," describes inventions for generating the basic CDMA waveforms used in CDMA wireless systems such as IS-95 and others. The same basic waveforms are also utilized in CDMA systems proposed for third-generation standards. The inventions of the '459 Patent enable multiple callers in a CDMA wireless telecommunications network to efficiently use the same frequency band without mutual interference, allowing for greater system capacity and better link performance. QUALCOMM's pioneering efforts in the development of CDMA cellular technology have yielded more than 200 issued U.S. patents relating to CDMA and hundreds of issued and pending CDMA patent applications around the world. While no single patent is critical to QUALCOMM's coverage of second or third generation CDMA wireless standards because QUALCOMM holds dozens of patents that are essential to the leading standards, the '459 Patent covers fundamental techniques for achieving high capacity in such CDMA systems. More than 60 major manufacturers of telecommunications equipment have taken royalty-bearing licenses under QUALCOMM's patent portfolio.
