Idea–expression distinction

The idea–expression distinction or idea–expression dichotomy is a legal doctrine in copyright law that limits the scope of copyright to only the expression of manifestation of ideas, not ideas themselves. The principle is set out in article 9(2) of the TRIPS Agreement and thus followed in at least 164 countries.
