Software has become one of the most valuable intellectual property assets of modern businesses. An enterprise management system, mobile application, e-commerce platform, SaaS solution, or device-control software may represent months or even years of investment in personnel, technology, and financial resources.
However, the fact that a company has funded, developed, and commercially used software does not necessarily mean that issues concerning authorship, copyright ownership, and the scope of rights in the software are legally clear.
Disputes may arise when a developer leaves the company, an outsourced software provider retains the source code, a business partner copies the program, or the parties disagree over who legally owns the software.
For this reason, although copyright generally arises automatically without registration, copyright registration for computer programs remains an important legal measure for establishing evidence of ownership and strengthening the enforceability of software-related rights.

For this reason, although copyright generally arises automatically without registration, copyright registration for computer programs remains an important legal measure for establishing evidence of ownership and strengthening the enforceability of software-related rights.
This article by A.D.V.N Law Company Limited provides a practical guide to software copyright registration in Vietnam under the regulations applicable in 2026.
Yes. Under Vietnamese intellectual property law, a computer program is generally understood as a set of instructions expressed in the form of commands, codes, diagrams, or other forms which, when incorporated into a device operated by a computer programming language, is capable of causing a computer or device to perform a task or achieve a specific result.
Computer programs are protected in a manner similar to literary works, regardless of whether they are expressed in the form of:
- Source code;
- Object code; or
- Other appropriate forms of expression.
In practice, software that may qualify for copyright registration includes, among others:
- Enterprise management software;
- Accounting software;
- Point-of-sale software;
- Mobile applications;
- Web applications;
- SaaS platforms;
- Device-control software;
- Database management systems;
- Educational software;
- Financial software;
- Logistics software;
- AI-integrated software;
- Video games and other interactive programs.
It is important to note that copyright protects the original expression of the computer program, rather than automatically granting exclusive rights over every underlying idea, function, algorithm, business method, or technical concept implemented by the software.
In principle, copyright in a computer program arises when the work is created and expressed in a certain material form. Copyright protection does not depend on whether the software has been published, commercially released, or formally registered. Therefore, copyright registration is not a condition for the existence of copyright.
However, there is an important distinction between:
having copyright and having effective evidence to prove copyright ownership.
When a dispute arises, the party claiming copyright may need to prove issues such as:
- Who actually wrote the software?
- When was the software completed?
- Who financed and assigned the software development?
- Whether the disputed source code is the original version;
- Whether the company or the developer owns the economic rights;
- Whether copyright has previously been transferred to another party.
A copyright registration certificate can therefore provide useful documentary evidence regarding the work, the author, and the copyright owner as recorded at the time of registration.
For technology companies, the value of software generally extends far beyond the source code itself. It may reflect substantial investment in research, development, product design, testing, and commercialization. Registering software copyright may provide several practical advantages.
First, establishing evidence of ownership. A copyright registration certificate records key information such as:
- The title of the computer program;
- The author;
- The copyright owner;
- The date of completion;
- The publication status of the work.
This may serve as important supporting evidence in the event of a dispute.
Second, supporting enforcement against unauthorized copying. If another party copies source code or commercially exploits a program without authorization, a properly prepared copyright registration dossier can strengthen the copyright owner's position when seeking enforcement.
Third, clarifying rights between companies and developers. This is particularly important in software projects. The person who writes the software and the person or entity that owns the copyright are not necessarily the same.
For example, an employee may be the author because he or she directly created the software, while the employer may own certain copyright rights depending on the employment arrangement, assigned duties, contractual terms, and applicable law.
Correctly identifying authorship and ownership at the filing stage can significantly reduce the risk of future disputes.
Fourth, facilitating commercial transactions. A copyright registration certificate may also be useful when the software is involved in:
- Copyright assignment;
- Software licensing;
- Fundraising;
- Mergers and acquisitions;
- Capital contribution involving intellectual property;
- Franchising;
- Technology cooperation;
- Legal due diligence.
As a general rule, an author is the individual who directly creates the work. For a computer program, the author is typically one or more individuals who directly participate in the creative development of the software code.
A company cannot normally be identified as the “author” in the same sense as a natural person who directly creates the program. However, a company may be the copyright owner.
This distinction is frequently misunderstood when businesses prepare software copyright applications without legal assistance.
Software written entirely by one individual: That individual may be identified as the author.
Software jointly developed by several programmers: Where multiple persons directly contribute creatively to the software, they may need to be identified as joint authors.
A project manager, chief technology officer, or company director should not automatically be named as an author merely because of his or her managerial position if that person did not directly participate in creating the work.
This is one of the most important legal issues in software copyright registration. At least three common situations should be distinguished.
First, software developed by employees within their assigned duties.
Where software is created by employees while performing duties assigned by the company, the business should maintain documents demonstrating the legal basis for ownership, which may include:
- Employment contracts;
- Assignment decisions;
- Job descriptions;
- Software development instructions;
- Handover records;
- Other relevant internal documents.
A company should not rely solely on the fact that the programmer is its employee when determining ownership.
Second, software developed by a freelancer or independent contractor.
In this situation, a software development agreement, commissioned work agreement, or copyright assignment arrangement becomes particularly important. The agreement should clearly address matters such as:
- Ownership of source code;
- Copyright ownership;
- Rights to modify and upgrade the software;
- Commercial exploitation rights;
- Source code delivery obligations;
- Rights in future versions;
- Use of third-party software or libraries;
- Confidentiality obligations;
- The right to file copyright applications.
Third, software developed by an external software company.
A customer should not automatically assume that payment of the full development fee gives it ownership of all copyright rights. The development contract should be carefully reviewed to determine which rights have been assigned and which rights remain with the software provider.
Accordingly, before filing a copyright application, A.D.V.N generally recommends reviewing the software's chain of title rather than focusing only on the filing form.
The exact filing requirements depend on the applicant, the authors, and the manner in which the software was created. A typical software copyright application may include the following categories of documents.
6.1. Copyright registration application form
The application form must be completed in accordance with the applicable requirements and generally includes information such as:
- Title of the work;
- Type of work;
- Details of the author;
- Details of the copyright owner;
- Date of completion;
- Summary of the computer program;
- Publication information, where applicable;
- Legal basis for copyright ownership;
- Applicant information;
- Declaration regarding the accuracy of the filing.
The software title should be consistent throughout the application form, source code printout, interface materials, and ownership documents.
6.2. Copy of the computer program
This is a key component of the software copyright application.
The filing materials may include:
- An electronic copy of the computer program;
- Printouts of the software interface;
- Source code printed on A4 paper.
Where the source code is 100 pages or more, the printed source code may generally be prepared in selected portions comprising:
- The first 25 pages;
- 25 pages from the middle; and
- The final 25 pages.
The pages should be clearly numbered and should consistently represent the software version being registered.
6.3. Legal documents of the copyright owner
Depending on the applicant, supporting documents may include:
For individuals:
- Citizen identification documents;
- Passport; or
- Equivalent identification documents.
For companies or organizations:
- Enterprise Registration Certificate;
- Establishment decision; or
- Equivalent corporate documents.
6.4. Documents proving copyright ownership
Where the copyright owner is not the individual who directly created the software, evidence of ownership is particularly important.
Such documents may include:
- Assignment decisions;
- Employment contracts and work assignment documents;
- Commissioned work agreements;
- Software development contracts;
- Copyright assignment agreements;
- Inheritance documents;
- Gift agreements;
- Other documents proving lawful acquisition of copyright.
The documents should accurately reflect the manner in which the software was developed and the legal relationship between the parties.
6.5. Author's declaration
Where required, the author may need to confirm that he or she directly created the software and identify the legal circumstances under which the program was created.
For employee-developed software, this declaration should be consistent with employment and work assignment documents.
6.6. Consent of joint authors or joint copyright owners
Where there are multiple authors or copyright owners, the application should be reviewed to ensure that the necessary consent or approval of the relevant parties is properly documented.
6.7. Power of Attorney
Where the copyright filing is made through a representative, an appropriate Power of Attorney should be submitted. The authorization should clearly identify the parties, the relevant work, the scope of authority, and the period of authorization where applicable.
This is one of the most common concerns for software businesses, particularly where the software contains tens of thousands of lines of code.
For registration purposes, the filed copy of the computer program should adequately identify the software being registered, including the relevant source code and interface materials.
Where the source code is 100 pages or more, selected extracts may generally be submitted, including:
- The first 25 pages;
- 25 pages from the middle;
- The last 25 pages.
The number of pages is not the only issue that should be reviewed.
The information appearing in the following documents should also be consistent:
- Application form;
- Source code printout;
- Interface screenshots;
- Electronic copy;
- Work assignment documents;
- Author's declaration.
Businesses should also avoid combining unrelated software products or different versions into one application without a proper legal and technical basis.
Not necessarily. Where the source code exceeds the applicable page threshold, selected extracts may generally be used for the printed source code component.
However, before filing, businesses should carefully review the materials to ensure that they do not unnecessarily disclose:
- Login credentials;
- API keys;
- Passwords;
- Authentication tokens;
- Server access details;
- Customer data;
- Trade secrets;
- Third-party proprietary code.
Information that is not required to identify the copyrighted work and that creates unnecessary cybersecurity or confidentiality risks should be handled carefully before filing.
Yes. The filing copy of a computer program should generally include materials showing the software interface together with the relevant code.
Businesses should select representative screens that clearly illustrate the structure and main functions of the software, such as:
- Login screen;
- Home page;
- Dashboard;
- Main menu;
- Data management screens;
- Core operating screens;
- Mobile application screens, where applicable.
The submitted images should be clear and should correspond to the software version being registered. It should nevertheless be noted that copyright protection for computer programs and protection of graphic interface elements are not necessarily identical in scope. Where a software interface has significant independent creativity, additional forms of intellectual property protection may need to be considered.
The use of open-source code or third-party libraries does not automatically prevent copyright registration for the portions of software created by the applicant or its developers. However, the scope of ownership must be carefully identified. A company cannot claim copyright ownership over third-party code merely because that code has been incorporated into its software.
Before filing, businesses should review:
- Open-source libraries used;
- Applicable license terms;
- Attribution requirements;
- Source code disclosure obligations;
- Redistribution conditions;
- Third-party software components;
- The specific portions of code independently developed by the company.
For commercial software, open-source compliance should ideally be addressed throughout the development process rather than only at the copyright registration stage.
This has become an increasingly important issue in 2026. The use of artificial intelligence tools during software development does not automatically disqualify the software from copyright protection.
A key issue is whether there is sufficient human creative contribution.
For software developed with AI assistance, human contribution may include:
- Preparing software design specifications;
- Determining system architecture;
- Defining technical inputs and parameters;
- Providing structured instructions to an AI system;
- Selecting appropriate AI-generated outputs;
- Editing AI-generated code;
- Reorganizing program structure;
- Testing and debugging;
- Determining the final version of the software.
Where AI tools are used extensively, businesses should consider maintaining development records, design documents, version histories, and evidence demonstrating meaningful human involvement in the creation of the final software.
Software is often continuously updated, for example:
- Version 1.0;
- Version 1.1;
- Version 2.0;
- Web version;
- Mobile version;
- Customer-specific edition;
- New modules.
It is not necessary to file a new copyright application every time a minor bug is fixed or a few lines of code are changed.
However, where a new version contains significant changes to the source code, structure, functionality, or original expression, the business should consider registering the new version to maintain evidence corresponding to the product actually being commercialized.
For software that represents a core business asset, it may be useful to adopt a registration strategy based on major development milestones rather than registering only the initial version.
The procedure can generally be divided into the following steps.
Step 1: Identify the correct author and copyright owner
This is the most important preliminary step.
The business should determine:
- Who actually wrote the software?
- How many authors are involved?
- Was the software created within assigned employment duties?
- Is the company legally entitled to copyright ownership?
- Was an outsourced provider involved?
- Have any rights previously been assigned?
Step 2: Identify the software version to be registered
The following should be clearly confirmed:
- Software title;
- Version;
- Completion date;
- Publication status;
- Corresponding source code.
Step 3: Prepare the software materials
The applicant should prepare the required source code extracts, interface materials, and electronic program copy.
Step 4: Prepare ownership and supporting documents
For company-owned software, particular attention should be given to employment documents, work assignment records, commissioned development agreements, and copyright transfer documents.
Step 5: Complete and file the application
The filing may be made through the filing channels permitted under applicable law, including direct submission, postal filing, or electronic filing where available.
Step 6: Monitor examination
If the application contains incomplete or inconsistent information, the competent authority may request amendments or additional documents.
Step 7: Obtain the Copyright Registration Certificate
Where the application satisfies the applicable requirements, the competent authority will issue a Copyright Registration Certificate for the computer program.
Software copyright applications are processed in accordance with the statutory timeline applicable to copyright registration.
Where the application is incomplete, inconsistent, or legally insufficient, the competent authority may request amendment or supplementation.
The actual processing time therefore depends significantly on whether the application is properly prepared from the outset.
For software applications, delays often arise not from the source code itself but from issues such as:
- Incorrect identification of the author;
- Lack of evidence supporting company ownership;
- Inadequate work assignment documents;
- Inconsistent information concerning the work;
- Missing signatures or consent of joint authors;
- Incomplete copyright transfer documentation.
Identifying the company as the author. A company may be the copyright owner, but the author must normally be the individual who directly created the software.
Naming only the director or CTO as the author. A managerial position does not itself establish authorship where the person did not directly participate in creating the program.
Lack of work assignment documents. This is a common issue where software is developed by employees.
Outsourcing contracts that do not clearly address intellectual property ownership. Full payment of software development fees should not automatically be treated as proof that all copyright has been transferred unless the agreement clearly addresses ownership.
Source code that does not match the registered version. The software version, completion date, source code, and application details should be carefully reviewed for consistency.
Including third-party code within the claimed scope of ownership. This may create legal risks relating to ownership and software licensing.
Registering too late. Once a dispute has arisen, it may be significantly more difficult to reconstruct who created the software, when particular versions were developed, and who legally owns the rights.
A Copyright Registration Certificate should not be understood as granting exclusive rights over every idea or function implemented by the software.
For example, if a company develops software for online medical appointment booking, copyright registration does not mean that only that company may develop software containing an appointment-booking function.
Copyright primarily protects the original expression of the software, including its computer code.
Where a software product incorporates a novel technical solution and satisfies the applicable requirements, patent or utility solution protection may also need to be considered.
Where the software name or logo functions as a commercial identifier, trademark registration should be considered separately.
Accordingly, a valuable software product may require a combined intellectual property strategy involving:
Copyright + Trademark + Patent/Utility Solution + Trade Secret + Contractual Protection.
No. Copyright registration and trade secret protection serve different legal purposes.
Software businesses should continue to maintain appropriate source code governance measures, including:
- Repository access controls;
- Version and commit history;
- Account authentication;
- Data backup procedures;
- Non-disclosure agreements;
- Intellectual property clauses in employment contracts;
- Handover procedures when employees leave;
- Restrictions on source code copying;
- Release and version records.
In software disputes, Git histories, assignment emails, software specifications, development tickets, and system logs may become important forms of evidence.
Can unpublished software be registered?
Yes. Publication is not a prerequisite for copyright registration provided that the software has already been created and expressed in an appropriate form.
Can the same person be both the author and copyright owner?
Yes. Where an individual independently creates the software and owns the relevant copyright, that individual may be both the author and the copyright owner.
Can a company be the author?
Generally, no. A company may be the copyright owner, while authorship is attributed to the individual or individuals who directly create the software.
Can software developed by several programmers be registered?
Yes. However, the persons who actually made creative contributions should be properly identified in determining joint authorship.
Can a company register copyright for software created by a freelancer?
Yes, provided that there is an appropriate legal basis establishing the company's ownership, such as a commissioned development agreement, copyright assignment, or other valid ownership documentation.
Must software be re-registered after every update?
Not every minor update requires a new registration. However, registration should be considered for versions containing substantial changes to the software's original expression.
Does software copyright registration protect the application name?
Copyright registration for a computer program does not replace trademark registration for the application's name or logo.
Where the name functions as an identifier of goods or services in the marketplace, separate trademark protection should be considered.
Software copyright registration is not merely a matter of submitting source code and completing an application form.
For businesses, the more important question is often who legally owns the software and what documents prove that ownership.

Software copyright registration in Vietnam is an important component of intellectual property management for technology companies and software developers.
Although copyright generally arises automatically once a computer program has been created and expressed in a material form, a Copyright Registration Certificate can provide stronger documentary evidence concerning the work, the author, and the copyright owner.
Before filing, businesses should be able to answer three fundamental questions:
Who created the software?
Who owns the copyright?
What documents prove that ownership?
Addressing these questions correctly from the outset is important not only for copyright registration, but also for software licensing, assignment, investment transactions, due diligence, fundraising, and dispute resolution.
