"A small Canadian wireless company is threatening to take a huge
chunk of the technology industry to court.
"Ottawa-based Wi-LAN, which patents wireless products, is suing
around 18 of the tech industry's largest players over what it
claims are patent violations of Bluetooth technology. More
specifically, Wi-LAN is alleging that these companies--which
include Acer, Apple, Dell, Hewlett-Packard, Lenovo, Motorola, Sony,
and Toshiba--have all infringed on one of its U.S. patents for
selling PCs and mobile phones equipped with Bluetooth.
"Announced Thursday, the suit claims a violation of Wi-LAN's
U.S. Patent No. 5,515,369. Issued in 1996, the patent covers a
"method for frequency sharing and frequency punchout in frequency
hopping communications network."
