A Canadian company has launched litigation against Apple, Dell, HP and 19 other firms, alleging the defendants violated its WiFi and power-saving patents.

The company claims the named companies have infringed and continue to infringe its US patents 5,282,222, RE37,802 and 5,956,323 by making and/or selling various products, including wireless routers, modems and personal notebook computers that use them for WiFi and DSL connectivity.

“Wi-LAN has successfully negotiated patent licensing deals with a number of companies covering a broad range of patent families and technologies,” said Jim Skippen, Wi-LAN president and CEO.

“Our existing licensing agreements are a strong endorsement of the strength and validity of our valuable patent portfolio. While we prefer to resolve patent infringement through business discussions, we have consistently maintained that litigation was always a possibility when negotiations do not result in a license within a reasonable time.”

Other companies named in the lawsuit include: Acer, Atheros Communications, Belkin International, Best Buy, Broadcom, Buffalo Technology (USA), Circuit City Stores, D-Link, Gateway, Infineon Technologies, Intel, Lenovo, Marvell Semiconductor, Netgear, Sony, Texas Instruments, Toshiba, Westell Technologies, and 2Wire.

The suits were filed in the patent-holder friendly courts in the Eastern District of Texas, Marshall Division. Wi-LAN will be represented in this action by McKool Smith,
