Pharmaceutical products require a high level of quality assurance, regulatory compliance, and brand recognition. In addition to the company name and active ingredient, a medicine's brand name, logo, and other identifying elements appearing on its packaging may become valuable commercial assets.
However, the fact that a pharmaceutical product has obtained marketing authorization or is already sold on the market does not mean that its name or logo is automatically protected as a trademark.
Businesses should therefore consider trademark registration for pharmaceutical products at an early stage, preferably before making substantial investments in packaging, advertising, and distribution.
This article by A.D.V.N Law Company Limited provides a practical guide to pharmaceutical trademark registration in Vietnam under the regulations applicable in 2026.
GUIDE TO TRADEMARK REGISTRATION FOR PHARMACEUTICAL PRODUCTS IN VIETNAM IN 2026
Under the Nice Classification applicable in 2026, pharmaceutical products are primarily classified in Class 5.
Depending on the actual products, the specification may include:
Class 5: Pharmaceutical preparations; medicines for human purposes; pharmaceutical preparations for medical purposes; plant extracts for pharmaceutical purposes; vitamins for medical purposes; dietary supplements for medical purposes.
The exact specification should be determined according to the nature and intended use of each product.
Not every health-related product automatically falls within Class 5. Certain goods may belong to other classes depending on their composition, function, and manner of use.
Where a business uses the same trademark not only for pharmaceutical goods but also for retail, wholesale, or commercial services relating to pharmaceuticals, Class 35 may also be relevant.
For example:
Class 5: Pharmaceutical products; pharmaceutical preparations for human use.
Class 35: Retail and wholesale services relating to pharmaceutical products and medical supplies.
The scope is different:
- Class 5 protects the mark for the pharmaceutical goods themselves;
- Class 35 protects the mark for the relevant commercial services.
Businesses operating pharmacy chains or pharmaceutical distribution systems should therefore consider whether protection beyond Class 5 is appropriate.
Potentially yes, provided that the sign satisfies the legal requirements for trademark protection.
However, medicine names often require careful review because they may contain:
- Names of active ingredients;
- Pharmaceutical substances;
- Names of diseases;
- Therapeutic indications;
- Dosage forms;
- Strengths or concentrations;
-Descriptive elements.
A sign that merely describes the type, composition, function, or characteristics of a pharmaceutical product may lack distinctiveness or receive only limited protection.
For this reason, businesses should generally prefer invented or distinctive brand names rather than names composed mainly of descriptive pharmaceutical terminology.
A trademark search is not always legally required, but it is highly recommended.
A prior search is particularly important in the pharmaceutical sector because:
- A large number of pharmaceutical trademarks already exist;
- Many medicine names have similar structures;
- Some marks are derived from active ingredients or medical terminology;
-Conflicts may arise from similarity in spelling, pronunciation, or overall impression.
A preliminary search can help:
- Identify earlier identical or similar marks;
- Assess preliminary registrability;
- Detect risks before packaging is printed;
- Allow modification of the proposed brand before launch;
- Reduce the cost of rebranding later.
For pharmaceutical trademarks, the search should consider not only exact spelling but also pronunciation, word structure, and overall commercial impression.
A pharmaceutical trademark must be distinctive and must not fall within the statutory grounds for refusal under Vietnamese intellectual property law.
A mark may face objections if it:
- Is identical or confusingly similar to an earlier trademark;
- Merely describes the therapeutic function of the medicine;
- Consists primarily of an active ingredient or pharmaceutical substance name;
- Describes the disease or condition treated;
- Describes quality, dosage form, or characteristics of the product;
- Is excessively simple or commonly used;
- Contains elements excluded from protection by law.
A coined or distinctive name will generally have a stronger registrability position than a mark based mainly on descriptive elements such as “Pain”, “Cold”, “Vitamin”, or “Pharma”.
A typical application includes:
- Trademark application form;
- Trademark specimen;
- List of goods and services;
- Proof of payment of official fees;
- Power of Attorney where filed through a representative;
- Other supporting documents where required.
The goods and services should be accurately classified under the Nice Classification applicable on the filing date.
The basic procedure includes:
Step 1: Identify the trademark to be protected
The mark may consist of:
- A medicine name;
- A pharmaceutical brand name;
- A logo;
- A combined word-and-device mark.
Step 2: Classify the goods and services
Pharmaceutical products are primarily in Class 5. Class 35 or other classes may be considered depending on the business model.
Step 3: Conduct a trademark search
Assess preliminary registrability and earlier rights.
Step 4: File the application
The application is filed with the Intellectual Property Office of Vietnam.
Step 5: Formality examination and publication
The application is examined for compliance with formal requirements and is published after being accepted as formally valid.
Step 6: Substantive examination
The Intellectual Property Office of Vietnam examines the registrability of the mark, including its distinctiveness and possible conflicts with earlier rights.
Step 7: Registration
If the mark satisfies the legal requirements and the relevant fees are paid, a Trademark Registration Certificate is issued.
No.
These are entirely separate legal procedures.
Trademark registration
Trademark registration establishes industrial property rights over a sign used to distinguish goods or services.
Pharmaceutical marketing authorization
Marketing authorization concerns sector-specific regulatory requirements governing medicines and pharmaceutical products.
The fact that a medicine is authorized for circulation does not automatically create exclusive trademark rights over its name or logo.
Likewise, obtaining a trademark registration does not replace the legal requirements applicable to the marketing of pharmaceutical products.
The two processes should therefore be planned and managed separately.
As a practical strategy, businesses should consider the following sequence:
Select the proposed name → Conduct a trademark search → File the application → Make substantial investment in packaging and promotion.
If a company manufactures a large quantity of medicine boxes before discovering that the proposed mark conflicts with an earlier right, the cost of changing the product name, packaging, and branding may be substantial.
Potentially yes.
A pharmaceutical package may contain several types of intellectual property:
Brand name and logo → Trademark.
Graphic packaging design → Potential copyright protection as an applied art work.
Distinctive shape of a bottle, container, box, or other package → Potential industrial design protection.
For commercially important pharmaceutical products, businesses may therefore consider an integrated strategy involving:
Trademark + Copyright + Industrial Design.
Common issues include:
- Selecting a name too close to the active ingredient;
- Using a name that directly describes the product's function;
- Filing without a prior search;
- Searching only for exact matches and ignoring similar marks;
- Incorrect product classification;
- Using an overly narrow goods specification;
- Registering only the logo while failing to protect the word mark;
- Printing packaging before assessing trademark availability;
- Assuming that marketing authorization automatically provides trademark protection.
