Manufacturers of components embodying the CSIRO technology and companies using those components in their products declined the reasonable and non-discriminatory licences offered by the research organisation.
Not surprisingly, CSIRO turned to its lawyers.
April saw settlements with several companies including 3Com, Accton, Asus, Belkin, Buffalo Technologies, D-Link, Dell, Fujitsu, Hewlett-Packard, Intel, Microsoft, Netgear, Nintendo, SMC, and Toshiba.
The terms were not disclosed, but an aggregate of $1 billion was bandied around at the time and not denied by CSIRO.
According to a report in The Australian, CSIRO now has the rest of the industry in its sights.
The article quotes a CSIRO spokesperson as saying "We have licensed half the industry and now we're engaged in negotiations with the other half of the industry".
There's a suggestion that CSIRO will go after mobile phone vendors, among others. Wi-Fi is an increasingly common feature of higher-end handsets, including models from HTC, LG, Nokia, RIM (BlackBerry), Samsung, Sony Ericsson, and of course Apple.
Such actions do not affect the users of Wi-Fi devices, except to the extent that prices could increase slightly to offset the licensing fees.
