"necessarily infringed"? Does that mean that if ARM contributes code
that unnecessarily uses ARM-owned patents, people don't get the
implicit license and are liable?<o:p class=""> <br>

Isn't the point to limit patent claims *by* ARM on users of LLVM? I
don't see how this license would limit claims *on* ARM, nor why the
project would care about that. Unless the lawyers have managed to
corrupt the meaning of "on" in this case.<br>
