Copyright is a form of intellectual property that gives the author of an original work exclusive right for a certain time period in relation to that work, including its publication, distribution and adaptation, after which time the work is said to enter the public domain. Copyright applies to any expressible form of an idea or information that is substantive and discrete and fixed in a medium. Some jurisdictions also recognize “moral rights” of the creator of a work, such as the right to be credited for the work. Copyright is described under the umbrella term intellectual property along with patents and trademarks.

Copyright has been internationally standardized, lasting between fifty to a hundred years from the author’s death, or a shorter period for anonymous or corporate authorship. Some jurisdictions have required formalities to establish copyright, but most recognize copyright in any completed work, without formal registration.
