05/27/2004

Redline Communications Agrees to Pay Royalties

CALGARY, Canada - May 27, 2004 - Wi-LAN Inc. (TSX:WIN), a global provider of broadband wireless communications products and technologies, today announced that it has settled the legal action in Canada that it launched in July 2002 against a private Canadian company, Redline Communications. Redline produces a wireless device utilizing advanced orthogonal frequency division multiplexing (OFDM) technology, and it is Wi-LAN's belief that this device infringes Wi-LAN's W-OFDM patents, specifically Canadian patent number 2,064,975 and U.S. patent number 5,282,222. Redline has agreed to pay Wi-LAN a royalty for every advanced OFDM wireless device that it has produced and will produce in the future, regardless of where the devices are sold.

"We are pleased to see this matter brought to a conclusion that is favourable for both Wi-LAN and Redline," said Dr. Hatim Zaghloul, Executive Chairman, Wi-LAN Inc. "Our intention is to now move ahead with negotiating further licensing agreements for our intellectual property."
