The fairness theory of copyright is based on the premise that the law ought to give authors what they deserve; in other words, hard work should be rewarded and authors should retain control of the fruits of their labors. For example, exclusive rights afford creators a limited monopoly and the opportunity to profit from their work. Further application of this theory might involve fair compensation for contributors to composite works and increased protections for factual works (facts are not presently protected by copyright). This theory is particularly influential in common law countries such as the United States and United Kingdom.
