Scenario: a hybrid-rice breeder in the Mekong Delta discovers farmers multiplying and selling its hybrid seed without permission — after seven years of R&D. What legal tools can stop this, and what regulatory gates must a new variety pass before it can be sold?
Plant variety rights are a branch of intellectual property
Law on Intellectual Property 50/2005/QH11 protects plant variety rights as one of the objects of IP rights, alongside copyright, related rights and industrial property. Law 131/2025/QH15 amending the IP Law — effective 01/04/2026 — confirms this structure in its amended Article 4. The holder of a Plant Variety Protection Certificate has the exclusive right to commercially exploit the variety: producing, propagating, selling and exporting propagating material.
Protection requires novelty, distinctness, uniformity, stability and a suitable denomination — the DUS criteria Vietnam applies in line with the UPOV system. In practice the examination authority verifies these traits through field trials, not paperwork alone.
Trials and market approval: the mandatory gate before commercialization
Under the Law on Cultivation 31/2018/QH14 (effective 01/01/2020), a crop variety may only be produced and traded after it is recognized for circulation. Recognition requires trials: DUS testing plus testing of cultivation value and use value (VCU) under Vietnam’s ecological conditions.
A common pitfall: a variety protected abroad must still undergo trials in Vietnam before domestic commercial circulation, unless an exemption applies under an international treaty or sectoral regulation. Importing varieties for trial or research purposes requires a permit and phytosanitary compliance.
Three enforcement tracks against infringement
Vietnamese law provides administrative enforcement (fines, seizure, destruction of infringing propagating material), civil litigation (damages, provisional urgent measures by courts) and criminal liability where the elements of IP-infringement crimes under the Penal Code are met. In practice, the administrative track through the specialized inspectorate is the fastest way to stop infringing seed already in circulation.
What businesses should do
- File the protection application before wide-area trials or test sales — early disclosure can destroy novelty.
- Keep complete breeding and selection logs: the key evidence in variety-right disputes.
- Put technology transfer and licence contracts in writing and register them with the competent authority so they are enforceable against third parties.
- Monitor the market and notarize evidence of infringing seed before requesting administrative action.
Frequently Asked Questions
1. Does a farmer saving seed for the next season infringe variety rights?
The IP Law provides an exception for farmers using harvested product for replanting on their own holdings within the household scope — but not for propagating seed for commercial sale. Selling a protected variety without authorization is infringement.
2. Is a variety protected abroad automatically protected in Vietnam?
No. Plant variety rights are territorial. Protection in Vietnam requires filing with the Vietnamese authority, unless an international treaty to which Vietnam is a party provides otherwise on priority.
3. How long do variety trials take?
Depending on the species and cropping seasons, DUS and VCU trials typically run over at least two independent growing seasons to assess stability. Build this timeline into the commercialization plan from the start.
