Hello! \x0d\ \x0d\Patent protection is regional. It is based on country boundaries. In which country you apply, you will be protected in that country. \x0d\ \x0d\ Generally, when applying for a foreign patent, you must first apply for a domestic patent and file an international application within 12 months. We call it a pct international patent application. \x0d\ \x0d\pct international patent is divided into two parts. The first part is the international stage, which means your patent will be logged into the pct platform. An international search report will be issued for your reference 4 months after application, telling you, What is the international situation of your technology and whether there are any prospects for licensing. \x0d\ \x0d\The second part is called the national stage, that is, you can choose to enter various countries, such as the United States, South Korea, the European Union, etc. After entering the country, it will be reviewed and approved according to the patent law process of the country you enter. \x0d\ \x0d\Thank you!
