http://www.gnu.org/philosophy/words-to-avoid.html#IntellectualPropertyPublishers and lawyers like to describe copyright as ``intellectual property''---a term that also includes patents, trademarks, and other more obscure areas of law. These laws have so little in common, and differ so much, that it is ill-advised to generalize about them. It is best to talk specifically about ``copyright,'' or about ``patents,'' or about ``trademarks.''
The term ``intellectual property'' carries a hidden assumption---that the way to think about all these disparate issues is based on an analogy with physical objects, and our ideas of physical property.
When it comes to copying, this analogy disregards the crucial difference between material objects and information: information can be copied and shared almost effortlessly, while material objects can't be. Basing your thinking on this analogy is tantamount to ignoring that difference. (Even the US legal system does not entirely accept the analogy, since it does not treat copyrights or patents like physical object property rights.)
If you don't want to limit yourself to this way of thinking, it is best to avoid using the term ``intellectual property'' in your words and thoughts.
