The so-called exhaustion of rights principle (exhaustion of rights [ii]), also known as the principle of exhaustion of rights and the first sale principle, refers to the intellectual property rights products manufactured by the owner of the intellectual property rights or persons authorized by them. After it is put on the market for the first time, the right holder loses further control over it within a certain geographical scope, and the rights of the right holder are considered exhausted. Anyone who legally obtains the intellectual property product can freely dispose of the intellectual property product. The purpose of the system is to maintain normal market transaction order and protect the legitimate interests of operators and general consumers on the premise of protecting the legitimate interests of patentees.
