Aussies win WiFi patent suit

A federal court in Tyler, Texas has ruled that a patent owned by an agency of the Australian government is valid and covers the core technology found in current wireless devices.

In February, 2005 the Commonwealth Scientific and Industrial Research Organisation ("CSIRO") filed suit against Buffalo Technology, a Japanese manufacturer and Buffalo USA, its Austin, Texas-based subsidiary. The action alleged that Buffalo's 802.11a and 802.11g wireless devices infringe claims of United States Patent 5,487,069 ("the '069 patent"). The patent issued in September, 1996 and claims priority to an Australian filing in November, 1991.
