Like all complex legal matters "it depends".
The enforcement is based on patents and contracts signed for licensing those patents. There tend to be a new set of patents for each new ISA feature. That's half the reason why the virtualization extensions are different on Intel and AMD for instance; they didn't cross license that piece.
The patents are obviously public, but we can't answer all the questions about the contracts since those tend to be private (we have seen a couple publicly due to law suits however).
