The world of patent acquisition and enforcement is highly regional. Getting a patent in one country does not automatically grant protection in other countries. As a result, a patentee must file for several patents in each country in which he or she wants protection. But a patentee filing for patent protection regarding an invention made in the United States needs to take caution. That is, in the interests of national security, the U.S. imposes restrictions on the export of technical information.
