Understood, please allow me clarify. Not to get off-topic with copyright despite being an "older author", notwithstanding the sibling comments, I'd agree it's too long. Now, it's nice that patents time-out quite quickly, and indeed that motivates for useful development, but what I'm talking about is adding serial (AND) conditions that require they're capable of being used. Alice has a fresh patent on a method for manufacturing a drug. She can sell it to Bob who also runs a pharmaceutical company and is in the process of expanding his portfolio of medicines. If Alice sells it to Charlie who runs a hair salon and fashion company, because Charlie, who is not in the business of making medicines, she cannot sue or leverage using that patent in any way or it's immediately null and void. Charlie doesn't have an "interest" in the patent and so loses the patent by misusing it, without any further need to prove the patent invalid. Crazy as that may sound to some, I think its a reasonable amendment to present law.
