The regionality of patent right is the spatial restriction of right. Compared with general property rights, the regionality of patent property rights is particularly prominent. The owner of tangible property will not lose the property ownership of tangible property because he went to another country, but the patent right as intangible property right is generally valid only in the country that granted him exclusive rights, and in principle it does not take effect in other countries. No country will recognize the patent right obtained according to other countries' laws, which is the regionality of patent right. This regional feature is fundamentally determined by the nature of patent rights, because patent rights are directly confirmed by national laws and can only be obtained through specific applications and approvals.
In addition, international conventions or bilateral agreements on patent rights have expanded the geographical scope of patent rights.
