The exhaustion of patent rights is the product of American judicial precedent in the19th century, which has a history of more than 60 years. The system began in brummer case of 1852, and its basic principle was established in Adams case of 1873. At present, it has become the basic defense of patent infringement.
In the case of Bloomer v. McQuewan, the Supreme Court of the United States expounded the reasonable compensation theory of the principle of exhaustion of patent rights, and held that the application of the principle of exhaustion of patent rights was mainly due to two basic motives: the expectation of preventing the patentee from obtaining unfounded compensation and the extreme distrust of imposing permanent restrictions on personal property. If the patentee gets reasonable compensation, he can't continue to control the patented product under the pretext of patent right.
