Employee Inventions in Vietnam: Company Ownership of Filing Rights and Inventor Remuneration usually arises against the background where an engineer at the plant creates a commercially valuable technical solution during working hours using company equipment, and both sides believe the filing right is theirs.
This article approaches ownership and remuneration for employee inventions in the order a lawyer handles a real file: lock the legal basis in force on 20 October 2026, test that basis against the specific file, and only then turn to the sequence and risks of ownership and remuneration for employee inventions.
The legal framework governing ownership and remuneration for employee inventions
The legal ground for ownership and remuneration for employee inventions is the Law on Intellectual Property No. 50/2005/QH11 through its 2009, 2019 and 2022 amendments and the amendment by Law 131/2025/QH15, implemented with Decree 65/2023/ND-CP, and on that ground the principle to hold is that under Article 86 of the Law on Intellectual Property, the right to register an invention created with an organisation’s funding and material facilities or under an assigned task belongs to that organisation unless the contract agrees otherwise, and Article 135 obliges the owner to pay the inventor remuneration as agreed or at the statutory level absent agreement Partners and banks usually read ownership and remuneration for employee inventions through their own lens before the state authority does, and their first question almost always circles around who owns an invention created by an employee in the course of work, so a written answer prepared in advance is not optional.
The labour side of ownership and remuneration for employee inventions must be read across Articles 42 and 43 of the Labour Code 45/2019/QH14 on restructuring and labour usage plans, Article 46 on severance allowance, Article 47 on job-loss allowance, and Decree 219/2025/ND-CP replacing Decree 152/2020/ND-CP on work permits, and read together they show ownership and remuneration for employee inventions stands only when an engineer at the plant creates a commercially valuable technical solution during working hours using company equipment, and both sides believe the filing right is theirs When preparing the file for ownership and remuneration for employee inventions, the company should test this point against the issue of how much remuneration must the company pay an employee-inventor, and how is it calculated from the outset, because waiting for the receiving authority to request supplements usually delays ownership and remuneration for employee inventions by weeks against plan.
Articles 138 to 149 of the Law on Intellectual Property frame every industrial property transfer, in which the assignment contract must be in writing and registration with the IP authority decides the transfer’s effect in the cases prescribed by law, and that frame locks ownership and remuneration for employee inventions at the point that a company with no invention clause in its labour contracts and late remuneration usually discovers the dispute exactly when the key employee leaves carrying all knowledge of an unfiled solution, turning an IP asset into a trade-secret leakage risk In the practical handling of ownership and remuneration for employee inventions, this detail is where files are most often sent back, because companies prepare the part on what should internal invention rules state to avoid disputes from the experience of a previous deal while the licence conditions of the current case have already changed.
Analysing the questions investors ask around ownership and remuneration for employee inventions
The question of who owns an invention created by an employee in the course of work is where the hidden cost of ownership and remuneration for employee inventions usually sits, because handling it superficially spawns another round of registration amendments and explanations that no project team budgeted for at the start. Analysing the question of how much remuneration must the company pay an employee-inventor, and how is it calculated requires separating what the law states clearly from what still depends on the local handling authority’s practice, because mixing the two is the source of most wrong decisions around ownership and remuneration for employee inventions.
The question of what should internal invention rules state to avoid disputes deserves its own internal paper for ownership and remuneration for employee inventions, stating the basis, the responsible owner and the completion mark, instead of an oral answer in a meeting that each person remembers differently. On the question of how is it handled if a departing employee files personally for an invention made at the former company, the answer cannot be separated from the specific file of ownership and remuneration for employee inventions, because the same issue placed in two companies with different licences and tax histories yields two different handling conclusions.
Advisory practice shows ownership and remuneration for employee inventions usually fails not at a big step but at one small postponed detail, and that detail almost always belongs to the group of issues the question of what should internal invention rules state to avoid disputes touches.
A safe implementation sequence for ownership and remuneration for employee inventions
- Open ownership and remuneration for employee inventions with a review session involving all three sides, legal, accounting and operations, because missing any one side means the plan gets rebuilt when that side finds its own problem.
- Lock the framework agreement for ownership and remuneration for employee inventions before touching state procedures, allocating clearly who bears the cost and who bears obligations arising before and after the effective date, especially around the issue of how much remuneration must the company pay an employee-inventor, and how is it calculated.
- Run the registration part of ownership and remuneration for employee inventions on a one-change-at-a-time principle, verifying the returned result after each step, instead of sending many changes at once and locking an early error into later steps.
- Check the cash flows of ownership and remuneration for employee inventions separately: which account receives, which account pays, and which vouchers prove the flow’s validity before the tax authority and the bank, including the investment capital account where a foreign investor joins the flow.
- After ownership and remuneration for employee inventions completes, run one post-completion review within a single reporting cycle to catch missed obligations, and record the execution lessons into the internal file for the next restructuring.
Risks to anticipate in ownership and remuneration for employee inventions
The most distinctive risk of ownership and remuneration for employee inventions lies in the following point. A company with no invention clause in its labour contracts and late remuneration usually discovers the dispute exactly when the key employee leaves carrying all knowledge of an unfiled solution, turning an IP asset into a trade-secret leakage risk. The second risk of ownership and remuneration for employee inventions rarely sits in the documents the parties sign with each other but in the state obligations running underneath in parallel, such as tax finalisation, the labour plan or licence adjustments, and it is that layer that returns as back-tax or penalties after ownership and remuneration for employee inventions has closed. A further risk of ownership and remuneration for employee inventions is the chain effect from the issue of how much remuneration must the company pay an employee-inventor, and how is it calculated: one unsettled point at the head of the chain amplifies into registration delay, tax figure discrepancies and lost partner confidence at its end.
In short, ownership and remuneration for employee inventions is only safe when the company handles all three layers together, the legal basis, the supporting file and the registration sequence, instead of optimising one layer and letting the other two become the bottleneck at completion. Before starting on ownership and remuneration for employee inventions, the investor should require a written mapping of the intended plan against the legal instruments in force on the implementation date, because that mapping is the document that best protects the company when regulators or partners ask questions later.
Frequently asked questions: ownership and remuneration for employee inventions
Who owns an invention created by an employee in the course of work?
Answering directly the question of who owns an invention created by an employee in the course of work: in ownership and remuneration for employee inventions, the first point to lock is the legal basis and original file of this very case, because conclusions drawn from another deal are reference only and cannot replace checking the instruments currently in force. More specifically, under Article 86 of the Law on Intellectual Property, the right to register an invention created with an organisation’s funding and material facilities or under an assigned task belongs to that organisation unless the contract agrees otherwise, and Article 135 obliges the owner to pay the inventor remuneration as agreed or at the statutory level absent agreement.
How much remuneration must the company pay an employee-inventor, and how is it calculated?
On the question of how much remuneration must the company pay an employee-inventor, and how is it calculated, practice in Vietnam shows the outcome of ownership and remuneration for employee inventions depends more on the quality of preparation before filing than on filing speed, because a file consistent across the relevant authorities is rarely sent back for amendment. More specifically, an engineer at the plant creates a commercially valuable technical solution during working hours using company equipment, and both sides believe the filing right is theirs.
What should internal invention rules state to avoid disputes?
The question of what should internal invention rules state to avoid disputes must be answered against the specific position of ownership and remuneration for employee inventions: the company should check its charter, licences and compliance history together before choosing an option, rather than deciding on a single factor. More specifically, a company with no invention clause in its labour contracts and late remuneration usually discovers the dispute exactly when the key employee leaves carrying all knowledge of an unfiled solution, turning an IP asset into a trade-secret leakage risk.
How is it handled if a departing employee files personally for an invention made at the former company?
For the question of how is it handled if a departing employee files personally for an invention made at the former company, the safe principle for ownership and remuneration for employee inventions is not to commit towards a third party before the legal basis and the handling plan are locked in writing, because an oral commitment is worth almost nothing once a dispute arises. More specifically, procedurally, the company must close out the whole file chain of ownership and remuneration for employee inventions, from the written agreement and registration with the competent authority to document retention, because a single missing link is enough to have the entire plan sent back to the start.
