Honestly, IP rights aren't a special case (setting aside patents, which isn't the topic of this thread); they're straightforward if you understand AR's theory of rights and property.

Another good reference is [2], but since AR's claims are hierarchial, you can't get the "whole story" very well from just looking up some specific topic.
