OK, so I get that a patent allows an inventor to protect their invention from exploitation, but I don't understand why a patent is transferrable - surely the idea is to allow an inventor to license the patent so that even if they couldn't realise a commercial product with their idea, they could allow others to do so, and still get something in return.

I could sympathise if Mirror Worlds were the originators of the patent, but as they bought it, then I get the impression that the whole thing stinks.
