AS for royalties they have been paid.
Former similar lawsuits were successfull for a reason, the plaintifs "laywered"
the defendants to death, paying out tons of money and finally outlasting them.
VIZIO, while a new name, is backed by older, more established companies.
They wont be such an easy victim to this nonsense.
Extrapolate the reasoning of the plaintiffs and you'd have to pay a royality
everytime you made a set, or WATCHED one.
But even if VIZIO sinks beneath the waves I dont care, I have a great set,
and it will certainly last till upgrade time (the two year mark).
I will bet its around long after your last CRT has fried and you cant find another , no matter how many dumpsters you "dive"
