I've read that there are very restrictive copyright/trademark issues and that company's who contract to use Gorilla Glass (Corning) are not allowed to advertise it as such without paying a fee (i.e. Apple). On the other hand, Corning, obviously retains the rights to offer their "customers" up as a reference.

I can see a company doing that. But it makes absolutely no sense to me, let them brag about it. That's free freaking advertising for you Corning! I swear some corporations just have absolutely no sense.
