I am happy about this, because its one of the rare instances that the IP system works properly.
For those who are un aware, the background is this;
CSIRO develops the core technologies of WiFi, and offers it as a standard, on the agreement that they will patent it, and licence it back for a small fee.
Big business agrees
CSIRO contacts big business, and reminds them of the agreement, to which big businesses reply with a dismissive hand wave. They failed to uphold their end of the agreement, and they were making money hand over fist with the new kit.
CSIRO politely reminds them for 5 years, that they owe them money, to which big business replies with the same dismissive hand wave
CSIRO unleashes the lawyers. This is a big risk for CSIRO, as they are a small organization, and it could be an expensive case.
Big Business, suddenly realising they are in the poo, and that they owe CSIRO a LOT of money now, attempt to have the patent invalidated via various means.
It seems they have now realized they have been caught with their d**ks in the cash drawer, and rather than have the CSIRO slam the drawer, they have settled.
This will be a boon for science, as CSIRO comes up with some neat stuff.
They ran the 4th ever computer in the world (On display in Melbourne Museum)
This isn't a case of patent trolling. This is a case of an organization following all the rules, and big businesses trying to shaft them on it.
