Have a world patent

No, patents applied for in China will not be protected by law abroad. The so-called regionality is the space (national) restriction of patent protection right. It means that the patent protection right granted by a country or region is only valid within the scope of that country or region, and other countries and regions have no legal effect, so the patent protection right is not confirmed and recognized.

If the patentee wants to enjoy the patent protection right in other countries, he must file a patent application again according to the relevant laws of other countries. However, if it is outside the provisions of international treaties and bilateral agreements, the situation will be discussed separately, otherwise no country or region will recognize the patent protection right granted by other countries or international intellectual property institutions.
