- What is an invention?
Under Article 4.12 of the Vietnam IP Law:
An invention is a technical solution in form of a product or process which is intended to solve a problem by applying laws of nature.
From the definition of the invention, it can understand that:
– Invention is a product or a technological process created by humans, not something (already existing in nature) discovered by humans.
– The essential attribute of an invention is a technical character because an invention is a technical solution to solve a problem.
- How many types of patents are in Vietnam?
There are two types of patents in Vietnam, including a Patent for Invention and a Patent for Utility Solution (Utility Model).
Note: Under Article 115.1.đ) of the Vietnam IP Law, it is possible to convert a patent application into a utility solution application and vice versa anytime before the IP Vietnam issues one of three decisions: (i) a decision to refuse to accept a valid application, a decision to refuse to grant a patent, or a decision to grant a patent.
- Protection conditions for inventions in Vietnam?
An invention shall be eligible for protection as a Patent for Invention if it meets the following conditions:
(i) being novelty,
(ii) involving an inventive step, and
(iii) being industrially applicable.
An invention shall be eligible for protection as a Patent for Utility Solution if it meets the following conditions:
(i) being novelty,
(ii) not being common knowledge, and
(iii) being industrially applicable.
- What is the difference between Patent for Invention and Patent for Utility Solution?
– A Patent for Invention must satisfy three criteria: (i) worldwide novelty, (ii) inventive step and (iii) industrial applicability. Meanwhile, a Patent for Utility Solution must satisfy two criteria: (i) worldwide novelty and (ii) industrial applicability, and must not be common knowledge.
It is easy to find that the patentability criteria of a Patent for Invention are higher than that of a Patent for Utility Solution.
– A Patent for Invention is valid for 20 years from the filing date, while a Patent for Utility Solution is valid for 10 years from the filing date.
– A request for substantive examination of a Utility Solution application must be filed within 36 months from the earliest priority date, compared to 42 months for a patent application.
- Subject matters not protected as inventions?
– Under Article 59 of the Vietnam IP Law, the following subject matters are not protected as invention:
- Discoveries, scientific theories, mathematical methods;
- Schemes, plans, rules and methods for performing mental acts, training domestic animals, playing games, doing business; computer programs;
- Presentations of information;
- Solutions of aesthetic characteristics only;
- Plant varieties, animal varieties;
- Processes of essentially biological nature for the production of plants and animals other than microbiological processes;
- Disease prevention, diagnostic and treatment methods for humans or animals.
– In addition, according to Article 8.1 of the Vietnam IP Law, subject matters that are contrary to the social ethics and public order and prejudicial to defence and security are also not protected as Invention.
- Are “Use” claims patentable in Vietnam?
Under Article 4.12 of the Vietnam IP Law, “Use” claims are presently regarded as non-patentable subject matters because they are not in the form of a parent or process. Therefore, such formats as the “Use” claim, the “Swiss-type” claim, and “second or further medical use” claim are currently unacceptable in the formality examination.
To be accepted by the IP Vietnam, an applicant may actively amend “use” claims to read them as “the composition, product… for use as…, or for use in…”. However, please bear in mind that the Vietnamese IPO’s acceptance is merely accepted provisionally as to formality, then such type of claim will be probably rejected in the substantive examination because the function/utility of the claimed subject is not the essential technical features of such subject matter under Circular 01/2007/TT-BKHCN.
- Is a patent valid in every country?
Patents are territorial rights. In general, the exclusive rights are only applicable in the country or region in which a patent has been filed and granted in accordance with the law of that country or region.
For example, if a patent is granted in Vietnam, it will only be valid for the whole territory of Vietnam.
- Should a patent/utility solution application be filed as soon as possible?
Yes, a patent/utility solution application should be filed as soon as possible.
Like most countries, Vietnam applies the “first to file” principle under Article 90 of the Vietnam IP Law. It can simply understand that if two people create the same invention independently, and both of them file their patent application with the IP Vietnam, then a patent will be only granted to the person who is the first to file a patent application, regardless of who creates the invention first.
- What is the “first to file” principle?
Under Article 90 of the Vietnam IP Law:
– If there are two or more patent applications filed for identical or equivalent inventions, a patent will only be granted to an application having the earliest priority date or filing date among the applications that satisfy all protection criteria.
– In case where there are two or more applications satisfying all protection criteria and having the same earliest priority or filing date, all of the applicants are now required to reach an agreement to proceed with one application only. Without such an agreement, all those applications shall be refused.
- Who Can File an Application for a Patent or a Utility Model?
Under Article 86 of the Vietnam IP Law:
– Authors create inventions by their own expenses and efforts;
– Individuals or organizations invests funds, facilities and material means to authors in the form of job assignment or hiring, unless otherwise agreed by the involved parties whose agreements are not contrary to the legal provisions;
– In case many individuals or organizations jointly create or invest to create an invention, that organization or individual may register an invention after obtaining the consent of the other individual or organization.

The complainant has the right to initiate a lawsuit at court if they disagree with the complaint settlement decision of the Minister of Science and Technology.
- Is it possible to file a patent application abroad before filing in Vietnam?
No. For the reasons of national security, inventions of Vietnamese organizations and individuals and inventions created in Vietnam (by Vietnamese or by foreigners) must be filed firstly in Vietnam before filing at any overseas patent offices, noting that:
(i) A patent application may be filed elsewhere after six (6) months of having been filed in Vietnam; and
(ii) A patent application is not allowed to file abroad when determined as a secret invention.
- What is the novelty of the invention?
Under Clauses 1&2 of Article 60 of the Vietnam IP Law, the requirements of the novelty of invention are:
- An invention is considered novel if it has not yet publicly been disclosed in the forms of use or written description or any other form, inside or outside the country, before the filing date of the patent application or before the priority date in case the application benefits a priority date;
- An invention is considered as not yet publicly disclosed if it is known to only a limited number of persons who are obliged to keep it secret.
- Exceptions to a lack of novelty:
Exceptions to a lack of novelty are provided in Clauses 3 & 4 – Article 60 of the Vietnam IP Law.
Accordingly, Vietnam applies a 12 month grace period from the disclosure date if one of the following events occurs:
– Where it is disclosed by a person entitled to registration as regulated in Article 86 of the Intellectual Property (IP) Law, regardless of any disclosure reasons;
– Where it is disclosed by a person who obtains information about the invention directly or indirectly from the persons as regulated in Article 86 of the IP Law;
– Where it was disclosed in patent applications or patents published by the state management agency in charge of industrial property (the IP Vietnam), but the publication is not in accordance with the provisions of the law or because the application is filed by someone who does not have the right to file.
Disclosures under Clauses 3 & 4 of Article 60 of the IP Law would not be considered as prior art when assessing the novelty and inventive step of the invention.
- What is the inventive step of the invention?
Under Article 61 of the Vietnam IP Law, the requirements of an inventive step are:
An invention is considered as involving an inventive step if, based on the technical solutions already publicly disclosed in the forms of use or written description or any other form inside or outside the country, before the filing date of the patent application or before the priority date in case the application benefits a priority date, the invention is inventive progress and cannot be easily created by a person skilled in the art.
- What is the industrial applicability of the invention?
Under Article 61 of the Vietnam IP Law, the requirements of the industrial applicability are:
An invention shall be considered to be capable of industrial applicability if it can be applied to mass production or manufacture of the product or it is possible to repeatedly apply the process that is the subject matter of the invention to get stable results.
- How long is the validity of a patent?
The period of protection is 20 years for patents for invention from the filing date, while it is 10 years for patents for utility solution from the filing date.
Annuity payments are required to maintain the validity. The first annuity is to be paid at the time of granting the patent and due dates for the second and subsequent annuities are the anniversary of the granting date of the patent. Within six months before the due date to pay an annuity, the patent owner must submit a request to pay the annuity. In case an annuity payment is not made by the due date, the patent will lapse on the due date. However, a six-month grace period is available with a surcharge of 10% of the fee for each month late.
- When can a third party file a pre-grant opposition?
Under Article 112 of the Vietnam Intellectual Property Law:
– Any third party can file an opposition with the IP Vietnam from the date a patent application is published on the Industrial Property Official Gazette until before the date of the decision to grant a patent.
– The opposition must be made in writing, accompanied by documents or cited information sources to support it.
The IP Vietnam always publishes patent applications on the Industrial Property Official Gazette (electronic version) on a monthly basis. You should check whether the patent application you wish to oppose has been published or not, so you can proceed to file the pre-grant opposition.
- Is it possible to amend the content of a patent application after it has been filed?
– Yes. An applicant may actively amend their patent application (filing a request for voluntary amendment) at any time before the IP Vietnam issues a final decision regarding the grant or refusal of the parent application.
