Converting a Patent Application Into a Utility Solution in Vietnam When Inventive Step Fails

Converting a Patent Application Into a Utility Solution in Vietnam When Inventive Step Fails usually arises against the background where the company’s patent application is assessed as failing inventive step, yet the solution is still new and industrially usable, making conversion into a utility solution the most viable rescue route.

The analysis below walks through the legal framework in force on 20 October 2026, how that framework applies to converting a patent application into a utility solution, a safe implementation sequence and the risks investors typically discover only once converting a patent application into a utility solution has reached its completion stage.

The legal framework governing converting a patent application into a utility solution

Substantive examination is a door the application must ask to open: Article 113 of the Law on Intellectual Property (amended by Law 131/2025/QH15) fixes a thirty-six-month request window plus the examination fee, and converting a patent application into a utility solution must be scheduled around that door because Vietnamese IP law lets an applicant convert an invention application into a utility solution application and vice versa before the IP Office issues a refusal or grant decision, with the original filing date preserved for the content already disclosed Partners and banks usually read converting a patent application into a utility solution through their own lens before the state authority does, and their first question almost always circles around if a patent application is refused for lack of inventive step, can it be converted into a utility solution, so a written answer prepared in advance is not optional.

Reading converting a patent application into a utility solution through the Law on Intellectual Property No. 50/2005/QH11 (amended in 2009, 2019, 2022 and by Law 131/2025/QH15) with Decree 65/2023/ND-CP, the first distinction is whether the right arises by registration or automatically, and on that distinction the lesson is that the company’s patent application is assessed as failing inventive step, yet the solution is still new and industrially usable, making conversion into a utility solution the most viable rescue route When preparing the file for converting a patent application into a utility solution, the company should test this point against the issue of what is the conversion procedure, and is the filing date retained from the outset, because waiting for the receiving authority to request supplements usually delays converting a patent application into a utility solution by weeks against plan.

Article 93 of the Law on Intellectual Property fixes title terms from the filing date: 20 years for an invention patent, 10 years for a utility solution patent, 5 years for an industrial design patent renewable twice for 5 years each, and 10 years for a trademark certificate renewable repeatedly, and these marks set the timetable of converting a patent application into a utility solution because waiting for the formal refusal before considering conversion is the most common timing mistake, because once the decision issues the conversion right is gone and only complaint or a fresh application with a much later priority date remains In the practical handling of converting a patent application into a utility solution, this detail is where files are most often sent back, because companies prepare the part on how much does conversion cost from the experience of a previous deal while the licence conditions of the current case have already changed.

Analysing the questions investors ask around converting a patent application into a utility solution

On the question of if a patent application is refused for lack of inventive step, can it be converted into a utility solution, what the investor needs is a conclusion immediately applicable to converting a patent application into a utility solution rather than a general principle, and that conclusion must rest on the original instruments in force, not on oral summaries passed between project teams. Answering the question of what is the conversion procedure, and is the filing date retained correctly starts from the company’s own registration documents in converting a patent application into a utility solution, because the same question put to two different registration files receives two different procedural answers.

The question of how much does conversion cost is where the hidden cost of converting a patent application into a utility solution 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 which tactic is better: converting, or amending and arguing on 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 converting a patent application into a utility solution.

Placing converting a patent application into a utility solution beside a similar completed deal shows the decisive difference rarely lies in the parties’ will, but in whether the core handling principle, namely that Vietnamese IP law lets an applicant convert an invention application into a utility solution application and vice versa before the IP Office issues a refusal or grant decision, with the original filing date preserved for the content already disclosed, was respected or skipped from the start.

A safe implementation sequence for converting a patent application into a utility solution

  • Delimit the whole foundation file of converting a patent application into a utility solution: original contracts, licences, internal minutes and obligations not yet closed, marking which documents lack signatures, lack registration or have expired.
  • Identify the competent authority for each workstream of converting a patent application into a utility solution and build a dependency schedule, which item must finish before which, instead of filing everything at once and being sent back piecemeal.
  • Turn the questions clients stumble on most around converting a patent application into a utility solution, especially how much does conversion cost, into a decision list to be locked by resolution or written agreement before the implementation date.
  • Complete the registration changes that converting a patent application into a utility solution drags with it, cross-checking particulars across the business registry, investment authority, tax authority and bank so no discrepancy remains in name, address or representative.
  • Close the converting a patent application into a utility solution file with a handover list stating what is done, what is still open and who owns each open item, avoiding an organisation-wide assumption that everything ended while one obligation stays live.

Risks to anticipate in converting a patent application into a utility solution

The most distinctive risk of converting a patent application into a utility solution lies in the following point. Waiting for the formal refusal before considering conversion is the most common timing mistake, because once the decision issues the conversion right is gone and only complaint or a fresh application with a much later priority date remains. The second risk of converting a patent application into a utility solution 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 converting a patent application into a utility solution has closed. The third risk of converting a patent application into a utility solution lies in the issue of what is the conversion procedure, and is the filing date retained when it is settled only orally between project teams: each side remembers a different version, and when interests collide no version is strong enough to serve as evidence.

The right way to read converting a patent application into a utility solution is as a dependency chain, not a single procedure: the right basis with the wrong file still fails, and the right file in the wrong sequence still gets returned. The cheapest investment in converting a patent application into a utility solution is therefore always review time before signing, and the dearest cost is always repair after the parties have committed to each other and to the state authority.

Frequently asked questions: converting a patent application into a utility solution

If a patent application is refused for lack of inventive step, can it be converted into a utility solution?

On the question of if a patent application is refused for lack of inventive step, can it be converted into a utility solution, practice in Vietnam shows the outcome of converting a patent application into a utility solution 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, Vietnamese IP law lets an applicant convert an invention application into a utility solution application and vice versa before the IP Office issues a refusal or grant decision, with the original filing date preserved for the content already disclosed.

What is the conversion procedure, and is the filing date retained?

The question of what is the conversion procedure, and is the filing date retained must be answered against the specific position of converting a patent application into a utility solution: the company should check its charter, licences and compliance history together before choosing an option, rather than deciding on a single factor. More specifically, the company’s patent application is assessed as failing inventive step, yet the solution is still new and industrially usable, making conversion into a utility solution the most viable rescue route.

How much does conversion cost?

For the question of how much does conversion cost, the safe principle for converting a patent application into a utility solution 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, waiting for the formal refusal before considering conversion is the most common timing mistake, because once the decision issues the conversion right is gone and only complaint or a fresh application with a much later priority date remains.

Which tactic is better: converting, or amending and arguing on?

On the question of which tactic is better: converting, or amending and arguing on, the first thing to clarify for converting a patent application into a utility solution is whether it belongs to the basis layer, the file layer or the sequence layer, because each layer needs a different kind of evidence to answer and carries a different risk if answered wrongly. More specifically, procedurally, the company must close out the whole file chain of converting a patent application into a utility solution, 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.
