Are patents applied for abroad protected at home?

Not protected by law, regionality means that the patent right is a right limited by geographical scope and only valid within the legal jurisdiction. Except in some cases, according to the international convention for the protection of intellectual property rights, if an individual country recognizes the validity of the patent right approved by another country, the technological invention will be granted the patent right applied for by that country, and it is only valid within the scope of the patent-granting country, but it is not legally binding on other countries, and other countries do not undertake any protection obligations. However, the same invention can be patented in two or more countries at the same time, and its invention can be protected by law in all the applicant countries after it is approved.
