Based on this any research University or Organisation around the world would become a patent troll unless they start to use the 'research' aka patents they created.
Let me spell it out for you, CSIRO stands for Commonwealth Scientific and Industrial Research Organisation..... Its a Research Organisation that is funded partly by the Australian Govement and partly by the income it gains from patents it created based on its research. This what a Research Organisation do.... it works on new ideas, gets them to a usable stage and sells them on to other companies to use the idea/tech to make money. In return they get a cut of this all done via the patent system.
Would slashdot dare call Stanford University or Harvard University a patent troll? Hell no... Poor IT world. CSIRO asked for payment based on companies using there research when all the IT companies tried to steal the idea and play the mob card, ie if no one pays we don't have to!
CSIRO is very easy going and licences the work they do at very cheap prices, its not like they asked a over the top amount. Any money they do gain is feed back into future research projects and isn't paid out to shareholders or fat CEO's!
