Yeah, just to balance out the arstechnica view of things, the register article goes in to some of the detail:http://www.theregister.co.uk/2012/04/10/csiro_paten

Long story short: CSIRO did participate in the process through a third party (the first company they licensed their tech to). They also agree to the IEEE's request that they would licence the IP on 'fair, reasonable and non-discriminatory terms' (note: not free). When they approached vendors and made an initial offer of $4 a pop, vendors refused to pay and ended up in court. Honestly I think wifi vendors simply misjudged the probability of CSIRO taking them to court if they didn't cough up.
