Title:
Intellectual_property

Context:
Criticism of the term intellectual property ranges from discussing its vagueness and abstract overreach to direct contention to the semantic validity of using words like property and rights in fashions that contradict practice and law. Many detractors think this term specially serves the doctrinal agenda of parties opposing reform in the public interest or otherwise abusing related legislations; and that it disallows intelligent discussion about specific and often unrelated aspects of copyright, patents, trademarks, etc.

Question:
Which term is criticized as vague?

intellectual property
