I bet this is a very well understood concept but I'm not an attorney.

If the original "owner" is a corporation, then that corporation is an entity just like a person. The death of a corp I would guess is treated the same as the death of a person. The right (which is simply part of the corp's assets) go to particular entities (people and other corporations) such as the stock holders and creditors. Those entities may or may not excercise their rights -- but that doesn't really change much.
