I was told when I was programming video games for the Mattel Intellivision
that Philips had a patent that covered the detection of on screen collisions
of video objects by AND gates.
This was claimed to be the reason that the game that was included with the
Intellivision did not use moving objects ( it was entirely done with
backgound graphics ). The idea was that if Philips decided to sue,
they would not be able to get an injunction banning the sales of the
Intellivision itself, only individual games that they know used that
technology.
