I don't understand why you are saying this. The issue I brought up was giving a state-backed legal monopoly of a basic idea to a company. I have not said I'm in favour of giving a similar monopoly to an individual, just that it's a different discussion which frankly isn't very relevant here since the patent in question is owned by AT&T and NCR.
But to address what you said directly, I don't think it would be hard to have a system where patents are owned by an individual rather than a corporation. There's no fundamental law of the universe which says that patents must be assignable to corporations, or that patents must be assignable to someone other than the inventor at all. Though again, I am not advocating for such a system, and again, I am not sure why you are bringing it up.
