Exclusive right is a «legal monopoly», i. e. a right that belongs strictly and solely to one person or entity. Exclusive rights are somewhat similar to proprietary rights, but extend not to items, but to intellectual property i. e. the economically relevant inner informational subject matter of an object.
Exclusive rights have a territorial nature and are protected separately in each country. The government guarantees the rightholders’ ability to prohibit any and all third parties from using their intellectual property without due authorization.
