What is the effect of an international patent application?

The PCT is an international treaty with more than 145 Contracting States. The PCT makes it possible to seek patent protection for an invention simultaneously in a large number of countries by filing a single “international” patent application instead of filing several separate national or regional patent applications. The granting of patents remains under the control of the national or regional patent Offices in what is called the “national phase”.

File PCT Patent Application in Vietnam

In general terms, your international patent application, provided that it complies with the minimum requirements for obtaining an international filing date, has the effect of a national patent application (and certain regional patent applications) in or for all PCT Contracting States. Moreover, if you comply with certain formal requirements set out in the Treaty and Regulations, which are binding on all of the PCT Contracting States, subsequent adaptation to varying national (or regional) formal requirements (and the cost associated therewith) will not be necessary.

Who has the right to file an international patent application under the PCT?

You are entitled to file an international patent application if you are a national or resident of a PCT Contracting State. If there are several applicants named in the international application, only one of them needs to comply with this requirement.
