> non­exclusive, non­transferable, non­assignable (including by operation of law or otherwise), non­sublicensable 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.
