Confidentiality of Unpublished Patent Applications in Vietnam: Duties of the IP Office and Applicants usually arises against the background where in the window between filing and publication, a competitor needs only to learn what the company is working on to get a head start, so the confidentiality of the unpublished file is a real concern for the R&D team.
Rather than a generic overview, the content below follows confidentiality of unpublished patent applications across four layers: the governing instruments, their application to a real file, an implementation sequence that does not get sent back, and answers to the questions clients ask most about confidentiality of unpublished patent applications.
The legal framework governing confidentiality of unpublished patent applications
Reading confidentiality of unpublished patent applications through the Law on Intellectual Property No. 50/2005/QH11 (amended in 2009, 2019, 2022 and by Law 131/2025/QH15) with Decree 65/2023/ND-CP,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 before publication in the Industrial Property Gazette, the information in a patent application must be kept confidential under the Law on Intellectual Property as amended, and officials involved in processing who leak secrets causing loss to the applicant face discipline and liability for damages One practice point to remember about confidentiality of unpublished patent applications is that every document signed around the issue of is the information in an unpublished patent application kept confidential must be consistent with the particulars registered at the business and investment registries, because a single small discrepancy can stall the next step of confidentiality of unpublished patent applications.
Article 113 of the Law on Intellectual Property (as amended by Law 131/2025/QH15) allows the applicant or any third party to request substantive examination within the statutory window from the filing or priority date upon paying the examination fee, and this request-driven mechanism sits at the centre of confidentiality of unpublished patent applications because in the window between filing and publication, a competitor needs only to learn what the company is working on to get a head start, so the confidentiality of the unpublished file is a real concern for the R&D team Testing against the issue of how long is it from filing to publication shows that the line between internal work and registrable work in confidentiality of unpublished patent applications is drawn by the original documents, so the company must lock its legal basis before signing any commitment binding towards a third party.
The Civil Code No. 91/2015/QH13 protects freedom of commitment and agreement (Article 3) and regulates breach penalties (Article 418) and damages for breach of contract (Article 419), and these provisions are the legal footing of confidentiality of unpublished patent applications where real leaks rarely come from the examining authority but from the company’s own internal supply chain, such as a fabricator sent full drawings before filing, and once a solution is disclosed outside the official channel the source is almost impossible to trace Seen from the registry’s side, the file for confidentiality of unpublished patent applications is judged first on consistency, and the issue of how can early publication be requested to block competitors is where that consistency breaks most easily if the company does not self-review before filing.
Analysing the questions investors ask around confidentiality of unpublished patent applications
With the question of is the information in an unpublished patent application kept confidential, the common mistake is copying the approach of a similar deal in another market, while confidentiality of unpublished patent applications in Vietnam is governed by the registered documents and the applying practice of the local authority where the company sits. The question of how long is it from filing to publication sounds simple yet decides the true cost of confidentiality of unpublished patent applications, because getting this point wrong forces the company back into amending registrations, re-finalising tax or renegotiating with partners when everything seemed done.
On the question of how can early publication be requested to block competitors, what the investor needs is a conclusion immediately applicable to confidentiality of unpublished patent applications 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 how is it handled if IP Office staff disclose application information correctly starts from the company’s own registration documents in confidentiality of unpublished patent applications, because the same question put to two different registration files receives two different procedural answers.
Advisory practice shows confidentiality of unpublished patent applications 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 how can early publication be requested to block competitors touches.
A safe implementation sequence for confidentiality of unpublished patent applications

- Settle in advance the open issues clients ask about most around confidentiality of unpublished patent applications, in particular how can early publication be requested to block competitors, through a clear written agreement or resolution instead of leaving them to each party’s default reading when a dispute erupts.
- Carry out the registrations and change notifications relating to confidentiality of unpublished patent applications at the correct authority in their proper dependent order, and update the bank holding the investment capital account if the deal’s cash flows pass through it.

Risks to anticipate in confidentiality of unpublished patent applications
The most distinctive risk of confidentiality of unpublished patent applications lies in the following point. Real leaks rarely come from the examining authority but from the company’s own internal supply chain, such as a fabricator sent full drawings before filing, and once a solution is disclosed outside the official channel the source is almost impossible to trace. The second risk of confidentiality of unpublished patent applications 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 confidentiality of unpublished patent applications has closed. A third risk attached to confidentiality of unpublished patent applications arises from the issue of how long is it from filing to publication: when the parties do not fix the handling in writing beforehand, each reads it in its own favour and the conflict erupts exactly when confidentiality of unpublished patent applications no longer has a way back.
In short, confidentiality of unpublished patent applications 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 confidentiality of unpublished patent applications, 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.
