They don't change the name for copyright purposes, but LR3 is patented. By calling it GFL, many people won't recognize it as what it is, so they can continue to sell it w/o word getting back to the Australians. It's obviously working.......look at the post title...."what is GFL?" For the people in the know, they have a "research company" that sells "GFL". Word gets around to the right people in confidence, and they have enough customers who know what it really is and can justify the risk of selling it. Gropep does control who distributes it publically, but they also sell to labs that use it for "research", who can, in turn, start "research companies".
