LED lights

[freezetyle]

I could be way off here as I do not know much about patents and how far they go but seeing businesses like nano tuners got me thinking.

Couldn't someone come out with an array of led on a heat-sink that "coincidentally" fit inside of a lighting hood that is also supplied by that same supplier, and again "coincidentally" has a compatible driver? The parts could be sold as a sort of a retrofit idea. all portions being offered separately?
