That does no one any good except the seller. For any seller, this kind of thing is table-stakes (no one wants to sell someone a gun pointed at their head).

But if the seller is specifically concerned about their patent being used offensively on others (which I suspect was the original commenter's concern), then this provision is useless.

I think I am misunderstanding you. If they give much more, Google might as well just pay one to void their patent instead of assuming ownership.
