How do you file an international application?

There are two ways to obtain a patent overseas: filing directly abroad, and using the PCT international application system.

≫Direct filing in each individual country

– When filing directly abroad, you must file in the foreign country within 1 year from the earlier filing date.
The date of the first application is called the priority date, and if you file within 1 year from this priority date, the claim of priority can be recognized.

≫PCT international application

– A PCT (Patent Cooperation Treaty) international application refers to a system in which, in order to more easily obtain patents among the countries that have acceded to the Patent Cooperation Treaty, when an applicant files a PCT international application with their own national patent office while designating the countries in which they wish to file, that very date is recognized as the date on which the application was filed in each designated country.
