Patent registration in Vietnam

Legal basis

  • TPP Agreement;
  • Intellectual Property Law 2005, amended and supplemented 2009, 2019, 2022;

Regulations of the TPP Agreement

In the Trans-Pacific Partnership Agreement that Vietnam signed, in the section Related to Intellectual Property, specifically Article 18.37 TPP, this issue was mentioned as follows: “..each member country affirms that patents are granted for patents that are claimed by at least one of the following types: new uses for a known product, new methods of using a known product known, or new procedures for using a known product”.

Thus, according to the provisions of this article, Vietnam, a TPP signatory, will have to accept “usage patent” protection expressed in “product” or “process” claims of protection.

What is a usage patent?

Article 3.12 of the Intellectual Property Law stipulates that: “A patent is a technical solution in the form of a product or process to solve a defined problem by applying natural laws.”

A usage patent is considered a type of patent in which the applicant not only creates a new product or process but also addresses how that product or process can be used or applied in reality.

Usage patents are often detailed descriptions of how a new product or method can be integrated into a practical environment, solve specific problems, or provide outstanding benefits to users. It is not limited to describing the structure or operating principle of the product, but also talks about how it can be deployed and applied in real-life situations.

The patent relates to an anti-wear coating having high abrasion transparency.
