Canadian Wireless Vendor Sues Cisco For Patent Infringement

Broadband wireless communications vendor Wi-Lan Wednesday said it is suing Cisco Systems for unlicensed use of its technology.

In a lawsuit filed in Canada, Wi-Lan alleges that Cisco's Linksys and Aironet product lines utilize wideband advanced orthogonal frequency division multiplexing (OFDM) technology that infringes on several Wi-Lan U.S. and Canadian patents. Wi-Lan is seeking compensation for use of its intellectual property as well as punitive damages from Cisco, the company said in a statement.

"This legal action against Cisco puts the industry on notice that Wi-Lan will aggressively protect its patent rights," said Sayed-Amr "Sisso" El Hamamsy, president and CEO of Wi-Lan, Calgary, Alberta, in the statement.

The company said the suit is part of its escalating effort to pursue licensing and protect its intellectual property.

Wi-Lan in May settled a similar lawsuit against Redline Communications. It now counts Redline, Philips Semiconductor and Fujitsu Microelectronics of America among its licensees.
