If you're unfamiliar with this story (and who could blame you, it's so ridiculous), here's a primer. Psystar sells Mac clones with Leopard installed. Apple played the conspiracy theory card and then declared copyright infringement and sued. Psystar responded with a counter suit, filed Chapter 11, recovered, sued over Snow Leopard ... you know what? Just check the history here. It's an epic exercise in red tape manufacturing.
At this point, Psystar is like that cricket you hear but can't find. Ultimately harmless, hard to ignore and supremely annoying.
