Intellectual property refers to creations of the mind such as inventions, literary and artistic works, and symbols. There are two main categories of intellectual property: industrial property, which includes inventions, trademarks, industrial designs, and geographic indications; and copyright, which covers literary and artistic works like novels, poems, plays, films, musical compositions, and artwork. Copyright is a legal term that gives creators exclusive rights over their works when they are fixed in tangible forms of expression. It is important to respect copyright in order to reward creativity, follow legal mandates, and set a good example in educational communities. Works covered by copyright include literary works, databases, films, artwork, advertisements, maps and technical drawings.
