CHICAGO, Jan 26, 2005 (BUSINESS WIRE) -- PCTEL, Inc. (NASDAQ:PCTI), a global leader in simplifying mobility, announced today that the reexamination certificate for one of PCTEL's fundamental "soft" modem patents, United States Patent No. 5,787,305, has been issued. This patent will now become part of the patent infringement lawsuit filed against Lucent and Agere. The '305 patent is a fundamental invention that made software modems viable under modern operating systems such as Microsoft^™ Windows.

"The soft modem patent adds considerable strength to our infringement claims," said Marty Singer, PCTEL Chairman and CEO. "In addition to its potential impact on our lawsuit, we may have additional licensing opportunities," added Singer.

PCTEL exited the modem business in 2003. Since then, the company has licensed its modem patents to several modem suppliers, including Intel, Broadcom, 3COM and Silicon Laboratories. PCTEL remains in litigation with Agere, Lucent and U.S. Robotics. A Markman hearing pertaining to the dispute is scheduled for April 6, 2005.
