PCTEL Sues 3Com Corporation For Patent Infringement

PCTEL Sues 3Com Corporation For Patent Infringement CHICAGO, Mar 5, 2003 (BUSINESS WIRE) --

PCTEL, Inc. (Nasdaq: PCTI), a leading provider of Internet access products and wireless mobility software, announced today that it had filed a complaint against 3Com Corporation (Nasdaq: COMS) for its widespread use of a fundamental PCTEL modem patent. PCTEL's complaint also asks the court for a declaration that certain 3Com patents are invalid and not infringed.

"We have consistently informed the industry - customers, competitors and our shareholders - that we will protect our substantial investment in modem technology," said Marty Singer, PCTEL's Chairman and CEO. "Despite repeated efforts to resolve this matter outside of the courts, 3Com's apparent dismissal of our legitimate claims left us with no option but to seek legal redress," added Singer.

PCTEL has licensed its patents pertaining to V.34 (lower speed) and V.90 (56 KBPS) modems to over 20 industry participants. These patents are essential to the implementation of the International Telecommunications Union (ITU) recommendations for V.34 and V.90 modem technology. The ITU is a global, standards-setting body.

In addition to these patents, PCTEL owns other fundamental modem patents unrelated to ITU standards, including the one asserted against 3Com today, which deals with the ability of modems to operate in different countries and to reset country-specific parameters. This is not the first time that PCTEL has enforced its fundamental modem patents through litigation. In late 2001, the United States International Trade Commission (ITC) validated several of those patents in an infringement dispute with two other parties. As a result of that litigation, both of those companies took a license under PCTEL's modem patents.
