Was just looking at a past thread here on the topic and it's seems that it's a package deal; shape, tuner layout and the term "3+1".I actually am not totally positive how it all breaks down. I always thought they had legal rights to the 3+1 and 4+2 layout. I have not seen anyone else ever do it and loads of companies say that they have gotten cease and desists when they try to use either.
Sire would seem to be in the clear here.
