The Australian government technology agency CSIRO has reportedly reached settlements with all the companies it had been suing for patent infringement regarding a technology built into 802.11g and later Wi-Fi wireless networking. The patent covers portions of the orthogonal frequency division multiplexing (OFDM) implementation that first appeared in 802.11g. Although aspects of the patent were openly questioned by other players in the industry, CSIRO doggedly pursued 14 technology companies over patent infringement, including Japanese-owned Buffalo Technology, which had its products banned from the U.S. market for a time in part because CSIRO won a judgement against Buffalo.
