dingram17 writes "ABC News is reporting that six U.S. computer companies (Apple, Dell, Hewlett Packard, Intel, Microsoft and Netgear) are taking legal action to try to break a U.S. patent that the CSIRO holds on wireless networking. The CSIRO has patents on OFDM technology, as used in 802.11a and 802.11g. It has been alleged that the CSIRO demands $4 per chipset for the use of this technology. It appears that the patent in question is U.S. Patent 5,487,069 'Wireless LAN.' From a quick look, this appears to be a wide ranging patent."
