Wi-LAN Inc., a global provider of broadband wireless communications products and technologies, announced the beginning of a new phase in its intellectual property licensing strategy. Following the successful settlement of the Redline Communications lawsuit, the wide market acceptance of Wi-LAN’s W-OFDM technology, and Wi-LAN’s recent purchase of 17 patents and patent applications that relate to the implementation of Wi-MAX Certified(1) products, Wi-LAN is escalating its active pursuit of licensing and protecting its intellectual property. In that regard, Wi-LAN has commenced legal action in Canada against Cisco Systems Inc., a manufacturer and marketer of networking and communications products, for producing and marketing IEEE standard 802.11a and 802.11g devices without a license from Wi-LAN. Wi-LAN is seeking compensation for use of its intellectual property as well as punitive damages.

Cisco’s Linksys Division and Aironet product line utilize advanced orthogonal frequency division multiplexing (OFDM) technology and it is Wi-LAN’s belief that these devices infringe on Wi-LAN’s Canadian patent number 2,064,975 and Wi-LAN’s United States patents No. 5,282,222 and 5,555,268. Wi-LAN currently has intellectual property licensing agreements with Philips Semiconductor, Fujitsu Microelectronics of America and Redline Communications.

“This legal action against Cisco puts the industry on notice that Wi-LAN will aggressively protect its patent rights,” stated Sayed-Amr (Sisso) El Hamamsy, President & CEO of Wi-LAN. “Wi-LAN has consistently maintained that its patents are necessary for the implementation of the 2nd Generation WiFi Alliance(1) standards, IEEE 802.11a and 802.11g(1), and the WiMAX Forum(1) standards, IEEE 802.16(1) and the ETSI BRAN HiperMAN(1). It is our intent to collect, either directly or through component manufacturers, royalties from any company selling 802.11a, 802.11g or WiMAX Certified(1) equipment.”

Wi-LAN will continue to vigorously pursue its legal remedies when it believes that its intellectual property has been infringed upon.
