Pharmaceutical Patents serve as the “backbone” for the development of the global biopharmaceutical industry, particularly in 2026 as the world witnesses leaps in gene technology and personalized medicine. The pharmaceutical industry possesses a very distinct economic characteristic: the cost of Research and Development (R&D) for a new active ingredient can reach billions of dollars and span decades, yet the cost of copying that formula is incredibly low. Without a rigorous and effective patent protection system, pharmaceutical corporations would lack the economic incentive to reinvest in treatments for terminal illnesses. This article, prepared by the expert team at Trần & Trần, provides a comprehensive and in-depth look at the rights establishment roadmap, exclusive protection strategies, and legal challenges in enforcing pharmaceutical patents in Vietnam and internationally.
The Strategic Importance of Pharmaceutical Patents
In the era of digitalization and synthetic biology in 2026, a patent is more than just a legal certificate. It is a strategic asset that determines the survival of a pharmaceutical enterprise. A granted patent signifies that the owner has the exclusive right to produce and commercialize the product for a specific period (usually 20 years).
This exclusivity allows pharmaceutical companies to recover massive investment costs and generate profits to fund subsequent research projects. However, the boundary between protecting intellectual property rights and ensuring community access to affordable medicine is always a sensitive topic, requiring legal consultants to possess a multi-dimensional and sharp perspective.
Classification of Patents in the Pharmaceutical Industry
The Vietnam Intellectual Property Law and international treaties, such as the TRIPS Agreement, classify pharmaceutical inventions based on specific protected subjects. Identifying the correct type of invention is the first step in building a robust registration dossier.
Product Patents
This is the most important category with the broadest scope of protection. Product patents focus on the Active Pharmaceutical Ingredient (API) itself—for example, a new chemical formula that does not exist in nature or its derivatives capable of treating a disease. When owning a product patent, any other entity producing or selling this active ingredient, regardless of the method used, is considered to be infringing.
Process Patents
This category protects the method of manufacturing the pharmaceutical product. In many cases, the main active ingredient may have expired, but a business discovers a new manufacturing process that is more efficient, cost-effective, or environmentally friendly. For instance, a chemical synthesis process that increases the purity of an active ingredient from 95% to 99.9% can be considered a significant technical advancement.
Indication Patents (Second Medical Use)
This form of protection is for a new therapeutic use of a known medicinal substance. For example, a drug originally used to treat hypertension is later researched and found to effectively treat hair loss. Discovering this use requires rigorous and costly clinical trials; therefore, the law allows for the protection of this new indication to encourage innovation.
Conditions for Pharmaceuticals to be Granted a Patent in Vietnam
According to the Intellectual Property Law effective in 2026, to be granted a patent, a technical solution in the pharmaceutical industry must fully satisfy three core conditions:
Novelty
An invention is considered novel if it has not been publicly disclosed by use, written description, or any other form, either domestically or abroad, before the filing date or the priority date. In the pharmaceutical industry, maintaining data confidentiality before filing is paramount. Any scientific article or seminar disclosing details about the active ingredient prior to filing can strip the invention of its novelty.
Inventive Step
This is the condition that most frequently leads to disputes. The invention must be a technical advancement that a person with ordinary skill in the pharmaceutical industry could not easily create. For example, combining two known drugs into a single tablet without a clear synergistic effect is usually rejected for lacking an inventive step.
Industrial Applicability
The invention must be capable of being manufactured or mass-produced with stable quality. In pharmaceuticals, this means the drug formula must possess physicochemical stability and be producible at an industrial scale to serve the consumer market.
Evergreening Strategies and the Challenge of Extending Monopolies
Evergreening is a term used to describe the strategy of innovator pharmaceutical companies to extend the exclusive protection period for a drug whose original patent is about to expire.
Common tactics include:
-
Registering different polymorphs, derivatives, or salts of the old active ingredient.
-
Changing the dosage form (e.g., from a tablet to an injectable or a slow-release form).
-
Registering new dosages or new drug combinations.
From a legal perspective in 2026, intellectual property authorities are becoming increasingly strict with these types of applications to prevent excessive monopolies that hinder the development of generic drugs. Therefore, constructing arguments for an inventive step in Evergreening applications requires a deep understanding of both law and pharmacology.
International Pharmaceutical Patent Registration via the PCT System
For pharmaceutical enterprises with global ambitions, filing under the Patent Cooperation Treaty (PCT) is the optimal roadmap. The PCT system allows applicants to file a single application in one language to secure a priority date in over 150 member countries.
International Phase
Within 12 months of the first filing (usually a national application), the enterprise files a PCT application. Subsequently, WIPO performs a search and a preliminary assessment of the invention’s patentability. This result provides the enterprise with an overview of the risks and potential before committing to the massive costs of the next stage.
National Phase
Within 30 or 31 months (depending on the country), the enterprise must decide to enter target countries. Here, each national IP office (such as IP VIETNAM or the USPTO in the US) will independently examine the application according to their national laws. This roadmap provides pharmaceutical companies with a “golden” window of nearly three years to seek investment partners or conduct clinical trials before committing to costs in each market.
Dossiers and Specific Technical Requirements in Pharmaceutical Patents
A standard pharmaceutical patent dossier in 2026 requires not only the correct forms but also extremely high technical content.
Specification
The specification must fully and clearly disclose the technical solution. In pharmaceuticals, this includes structural formulas, detailed processes, and experimental examples. If the description is too vague, the patent may be rejected for “insufficient disclosure.”
Claims
This is the most critical part, defining the scope of the owner’s rights. Experts at Trần & Trần emphasize drafting claims that are comprehensive yet specific enough to prevent competitors from “designing around” the patent. A claim that is too broad is easily challenged, while one that is too narrow allows others to escape infringement by changing a minor detail.
Clinical Trial Data
While patents protect technical solutions, Data Exclusivity is a vital parallel mechanism. In Vietnam, this data is kept confidential for 5 years from the date the drug is granted a marketing authorization. This prevents generic companies from using the innovator’s data to register their own drugs, even if the patent has expired.
Challenges in Enforcing Pharmaceutical Patent Rights
Owning a patent is just the beginning. Enforcement is the real battle.
Competition from Generic Drugs
Generic companies always look for ways to enter the market as soon as a patent expires, or even seek to invalidate the patent through opposition procedures at the IP Office. Businesses need a Patent Portfolio Management strategy to respond to these legal attacks.
Compulsory Licensing
In public health emergencies (such as a global pandemic), the Government has the right to allow other entities to produce a drug without the patent owner’s consent to ensure health security. Although rare, this is a legal risk that pharmaceutical corporations must consider when investing in developing markets.

Strategies for Optimizing Pharmaceutical Patent Portfolios
To achieve the highest economic efficiency, a business should not rely on a single patent application. A “Patent Thicket” strategy is a wise choice. By registering an ecosystem of patents around the main active ingredient (including manufacturing processes, combination formulas, salt forms, etc.), the business creates multiple layers of barriers to prevent competitor entry.
Furthermore, conducting periodic Patent Searches is essential. This helps businesses detect competitors’ applications early that might hinder their own R&D activities, allowing for appropriate opposition measures or licensing negotiations.
Conclusion and Expert Advice
Pharmaceutical patents are the most complex type of intellectual property but also offer the highest value-added potential. As pharmaceutical and IP regulations in Vietnam increasingly align with international standards, delays or errors in the rights establishment phase can lead to irreparable losses.
Strategic advice for pharmaceutical enterprises is to approach intellectual property work from the very beginning of a research project. Close coordination between the scientific department and a professional legal consulting team will ensure that all creative achievements are enveloped in the strongest legal “steel shields.” The success of a pharmaceutical product on the market is based not only on its therapeutic efficacy but also on the strength of the exclusive patent it holds.
