Patents are regional. The so-called regionality is the space limitation of patent right. It means that the patents granted and protected by a country or region are only valid within the scope of that country or region, but have no legal effect on other countries and regions, and their patent rights are not confirmed and protected. If the patentee wishes to enjoy the patent right in other countries, he must file another patent application according to the laws of other countries. No country will recognize the patent rights granted by other countries or international intellectual property agencies unless it joins international treaties and bilateral agreements.
