In the context of increasing technological competition and innovation, patents are not only the result of research and development activities but also valuable intellectual property assets for businesses and inventors.
Patent registration is a legal procedure for establishing ownership rights over a technical solution that satisfies the protection requirements under intellectual property law. Once a patent is granted, the owner obtains exclusive rights to exploit, use, and prevent others from unauthorized use of the patented invention during the protection term.
Registering a patent helps businesses and inventors:
In Vietnam, the competent authority responsible for receiving and examining patent applications is the Intellectual Property Office of Vietnam (IP Vietnam).
A patent is a protection title granted by a competent state authority to recognize lawful ownership rights over a registered invention.
In Vietnam, there are two main forms of patent protection:
Granted to inventions that satisfy all of the following requirements:
Granted to technical solutions that:
Many businesses focus solely on production or commercialization without paying sufficient attention to patent protection at an early stage. In practice, delayed filing may result in the loss of protection rights or allow competitors to file first.
Patent registration offers several important benefits:
Protection of Technology and Technical Know-How
Patent owners have the exclusive right to prevent third parties from exploiting or using the invention without authorization.
Enhancement of Business Value
Patents are valuable intangible assets in fundraising, technology transfer, licensing, and M&A activities.
Competitive Advantage
Businesses owning patented technologies generally maintain stronger market positions.
Commercialization Opportunities
Patents may be licensed, assigned, or commercially exploited through partnerships.
Reduction of Legal Risks
Clear ownership rights help minimize intellectual property disputes.
Patent Protection Requirements in Vietnam
Not every idea or product is eligible for patent protection. Under Vietnamese intellectual property law, an invention must satisfy the following requirements:
An invention must be novel compared to the global state of the art before the filing date or priority date.
This means the technical solution must not have been publicly disclosed in any form, including:
Many businesses lose patentability because they publicly disclose products or technologies before filing a patent application.
The invention must not be obvious to a person having ordinary skill in the relevant technical field.
This requirement ensures that the invention represents a genuine technical advancement rather than a routine modification.
In practice, lack of inventive step is one of the most common reasons for patent rejection.
The invention must be capable of:
Purely theoretical ideas or impractical concepts generally do not satisfy this requirement.
Under Vietnamese intellectual property law, the following subject matter is not patentable:
Therefore, conducting a patentability assessment before filing is highly recommended.
Among these documents, the specification and claims are the most important because they directly determine the scope of protection.
The patent registration process in Vietnam generally includes the following steps:
Step 1 – Patentability Search
Assessing novelty and patentability of the technical solution.
Step 2 – Drafting the Patent Application
Preparing the specification, claims, and required documents.
Step 3 – Filing the Patent Application
Submitting the application to IP Vietnam.
Step 4 – Formality Examination
Reviewing the formal validity of the application.
Step 5 – Publication of the Application
Valid applications are published in the Industrial Property Gazette.
Step 6 – Substantive Examination
Assessing whether the invention satisfies patentability requirements.
Step 7 – Grant of Patent
If all requirements are met, IP Vietnam grants an Invention Patent or Utility Solution Patent.
Under current regulations:
Patent owners must pay annual maintenance fees to maintain validity.
Proper preparation at the initial stage can significantly reduce time and costs.
