Intellectual rights to magic methods refers to the legal and ethical debate about the extent to which proprietary or exclusive rights may subsist in the methods or processes by which magic tricks or illusions are performed. It is a subject of some controversy.
On one side, many magicians argue that methods represent "intellectual property" and that publication or sharing of methods should be subject to strict codes developed by magicians' organizations. On the other side, a range of people argue that publication of information about methods should not be subject to restrictions because knowledge should be freely available. The sharing of magic methods with non-magicians or the open publication of methods is referred to in the magic community as "exposure".
