The establishment of patents and other mechanisms that enforce intellectual property rights are a manner of rewarding effort and innovation. When a company devises an innovative product or a more efficient production technique, holding a patent allows them to exploit it in a exclusive regime, so that no one else can copy or profit from their idea. However, those rights are limited in time, that should be enough for them to recover the investment made to develop the innovation and to earn reasonable profits, and afterwards such innovation can be shared with others to foster efficiency in the economy as a whole.
