Wi-Lan Steps Up Patent Offensive

CALGARY, Canada -- Wi-LAN Inc. (TSX: WIN - News), a global provider of broadband wireless communications products and technologies, today announced that it has filed a letter of assurance with the IEEE Standards Association (IEEE-SA) for the patents and patent applications recently acquired from Ensemble Communications Inc. Wi-LAN's letter of assurance states that it is prepared to grant a license for the patents and patent applications to an unrestricted number of applicants on a worldwide, non-discriminatory basis on reasonable terms and conditions. Wi-LAN believes the infringement of these patents is unavoidable in any implementation of the IEEE 802.16 WirelessMAN Standard(1). The WiMAX Forum(1) intends to certify equipment designed to this standard.

"The acquisition of the Ensemble patent portfolio has strengthened our position within the 802.16 standard," said Dr. Hatim Zaghloul, Executive Chairman of Wi-LAN. "The acquisition of these patents is a significant enhancement to our WiMAX licensing strategy."

Wi-LAN believes its W-OFDM patents are relevant to all implementations of broadband wireless OFDM and is committed to supporting the ubiquitous implementation of OFDM in broadband wireless equipment and standards. Wi-LAN makes available for sale to all interested parties its W-OFDM technology and expertise and intends to make available its 802.16 MAC layer, WiMAX certifiable physical layer as silicon IP, WiMAX certifiable customer premise equipment and access point designs, and its system-on-chip for WiMAX Certified equipment.
