Machinery and equipment are often protected primarily through patents or utility solutions because their core commercial value commonly lies in technical structures, operating principles, and functional improvements. However, in many cases, the external appearance of a machine or device also has independent commercial value.
A coffee machine, lighting device, air purifier, medical device, industrial machine, or electronic product may perform functions similar to competing products while still creating a competitive advantage through its distinctive shape, proportions, surface configuration, lines, and arrangement of visible components.
In such cases, businesses should consider industrial design registration in addition to protection for technical solutions. This article by A.D.V.N Law Company Limited explains the key issues involved in registering industrial designs for machinery and equipment in Vietnam under the regulations applicable in 2026.
Yes, provided that the external appearance of the machinery or equipment satisfies the applicable statutory requirements.
Industrial design protection may be considered for a wide range of products, including:
- Industrial machinery;
- Food-processing machines;
- Coffee machines;
- Coffee roasting machines;
- Packaging machines;
- Cutting machines;
- Pressing machines;
- Pumps;
- Agricultural machinery;
- Electrical equipment;
- Electronic devices;
- Lighting equipment;
- Medical devices;
- Household appliances;
- Hand tools;
- Machine components;
Assemblies and detachable components capable of independent circulation.
The key point is that industrial design law protects the external appearance of the product, rather than its internal operating principle or technical solution.
For machinery and equipment, industrial design protection may focus on visible external features such as:
- Overall shape;
- Proportions among components;
- Lines and contours;
- Surface configuration;
- Shapes of visible assemblies;
- Arrangement of external parts;
- Combination of design elements;
- Colors, where color forms part of the claimed design.
For example, a lighting device may include:
- An elongated flat lamp body;
- Rounded ends;
- A central joint assembly;
- A short cylindrical connector;
- A distinctive proportion between the body and connector.
These elements may constitute the design features of the product.
By contrast, features such as:
- Power output;
- Voltage;
- Motor type;
- Transmission structure;
- Heat dissipation principle;
- Operating mechanism;
- Control algorithms;
are not themselves protected by industrial design rights.
To qualify for protection in Vietnam, an industrial design must satisfy the statutory requirements, including:
The design must not be identical to or insignificantly different from a design that has already been publicly disclosed before the filing date or priority date, subject to statutory exceptions.
For machinery and equipment, novelty may need to be assessed against disclosures both in Vietnam and internationally.
Relevant prior disclosures may appear in:
- Industrial design registrations;
- Published design applications;
- Websites;
- Product catalogues;
- E-commerce platforms;
- Videos;
- Trade exhibitions;
- Advertising materials;
- Products already available on the market.
The design must create a sufficient degree of difference from known designs and must not be easily created by a person having ordinary knowledge in the relevant field.
Minor modifications to common product features may not be sufficient.
The design must be capable of serving as a model for repeated manufacture of products by industrial or handicraft methods.
Machinery and equipment manufactured through machining, casting, molding, CNC processing, pressing, cutting, or other industrial manufacturing methods will generally satisfy this requirement where the design can be reproduced consistently.
Not every visible feature of a machine can necessarily be monopolized as an industrial design.
In particular, Vietnamese law excludes from industrial design protection the external appearance of a product that is dictated solely by its technical characteristics.
For example, if a component must necessarily have a particular shape in order to:
- Fit onto a shaft;
- Connect with another component;
- Ensure fluid flow;
- Transmit force;
- Establish electrical contact;
- Meet a mandatory technical standard;
it is necessary to assess carefully whether the shape represents a protectable design choice or is entirely dictated by technical function.
This distinction is especially important for machinery because design features and technical features often overlap.
Registering the entire machine is not always the most effective strategy.
Businesses should identify which part actually carries the greatest design value and is most likely to be copied by competitors.
The industrial design may be filed for the entire product.
Examples include:
- Coffee machines;
- Air purifiers;
- Projectors;
- Machine tools;
- Medical devices.
It may be appropriate to consider separate protection for a component intended for assembly into a complex product, provided that the component satisfies the relevant legal requirements.
Potential examples include:
- Lamp assemblies;
- Equipment housings;
- Handles;
- Covers;
- Control units;
- Machine heads;
- Modules;
- Detachable machine parts.
This approach may allow the applicant to focus protection on the commercially important component most vulnerable to imitation.
Not every internal part can necessarily be registered separately as an industrial design.
The applicant should consider:
Where a component is completely internal and not visible during normal use, industrial design protection may be unavailable or limited.
Machinery is often offered in several models, such as:
Where the versions share the same overall design concept and differ only in insignificant details, it may be possible to file them as variants of the same industrial design, subject to unity requirements.
Variants should not differ significantly from the basic design or from one another.
Where the different models have materially different appearances, separate applications should be considered.
For industrial design protection, the set of drawings or photographs is critically important because the scope of protection is determined primarily by the appearance shown in those representations together with the written description.
For machinery and equipment, the representation set should generally include the views necessary to disclose the design fully, such as:
Depending on the nature of the product, the number and type of views may be adjusted.
The views must be consistent
A feature shown in the perspective view should correspond accurately to the same feature in the orthographic views.
Applicants should avoid inconsistencies such as:
Lines should be clear
The drawings should clearly disclose the product's external configuration.
Unnecessary technical details should be removed
Industrial design drawings should generally avoid:
CAD-based drawings may be preferable
For complex machinery, CAD files converted into clean industrial design drawings often provide advantages such as:
Raw engineering drawings should not normally be filed without review because they often contain excessive technical information unrelated to industrial design protection.
Generally, the purpose of industrial design registration is to protect the visible external appearance of the product.
It is therefore usually unnecessary to show internal parts such as:
unless those parts form part of the claimed visible design.
Including excessive internal detail may:
A typical industrial design description should include:
For machinery, the description should focus on visible design features, rather than becoming a technical patent-style description.
For example, instead of writing:
The joint assembly allows the lighting angle to be adjusted from 0 to 120 degrees.
it is usually better to describe the visual form:
The joint assembly is positioned between the connector and the device body and has a linked configuration comprising symmetrically arranged hinge portions.
The objective is to describe the appearance, not the operating principle.
The name should be:
Suitable examples include:
Names such as the following are generally inappropriate:
The design title is a legal identification of the product, not advertising language.
The scope of protection should focus on the combination of fundamental design features that distinguish the design.
For machinery, the description may address:
For example:
The industrial design sought to be protected is a lighting device having an elongated flat body with rounded ends, a joint assembly positioned at the rear of the body, and a short cylindrical connector coupled to the joint assembly, the components being arranged as an integrated overall configuration as shown in the accompanying drawings.
The scope should generally avoid unnecessary references to:
Only where necessary to clarify the visual appearance and where consistent with the drawings.
For example:
The device includes a metal body and a plastic connector.
This may help identify different portions of the product.
However, where the commercial objective is to protect the shape regardless of material, unnecessary material limitations should be avoided.
A useful strategic question is:
If a competitor copies the same appearance but replaces aluminum with plastic, should the registered design still be relevant?
If the answer is yes, the applicant should be cautious about unnecessarily limiting the design by material.
As a general strategy, yes.
Public disclosure may occur through:
Because novelty is a fundamental requirement, public disclosure before filing can create serious risks, subject to limited statutory exceptions.
The safer principle is:
File the industrial design application first – launch the machine later.
A search is not always legally mandatory, but it is highly recommended.
For machinery and equipment, a prior search can help:
Search sources may include:
A typical application includes:
Industrial design application form
Prepared using the form applicable on the filing date.
Industrial design description
Containing the required legal sections.
Set of drawings or photographs
The representations should fully and consistently disclose the claimed appearance.
Proof of payment of official fees
In accordance with the fee schedule applicable at the time of filing.
Additional documents where applicable
These may include:
Step 1: Assess the product
Determine:
Step 2: Conduct a preliminary search
Review earlier publicly disclosed designs.
Step 3: Define the protection strategy
Decide whether to file:
Step 4: Prepare the drawings or photographs
This is often the most important drafting stage.
Step 5: Prepare the description and scope of protection
The wording should be fully consistent with the drawings.
Step 6: File the application
The application is submitted to the Intellectual Property Office of Vietnam through the filing methods permitted under applicable law.
Step 7: Monitor examination
The application proceeds through the industrial property examination process.
Where formal or substantive issues arise, the Intellectual Property Office of Vietnam may issue an official notification allowing the applicant to respond or amend the application within the permitted scope.
Step 8: Obtain the Industrial Design Patent
Where the application satisfies the legal requirements, the Intellectual Property Office of Vietnam grants an Industrial Design Patent.
This distinction is particularly important.
Assume a company develops a new cutting machine.
The machine includes:
In this case:
Patent or utility solution protection
May protect the technical solution, including:
Industrial design protection
May protect:
The two forms of protection may exist simultaneously.
For valuable machinery, both should often be assessed.
Yes, provided that the respective legal requirements are met.
For example, a coffee roasting machine may include:
A new bean-agitation mechanism → Patent or utility solution.
A distinctive external housing → Industrial design.
Product name and logo → Trademark.
Control software → Copyright in a computer program.
A single machine may therefore be protected through multiple intellectual property rights.
The most effective strategy is not necessarily to select only one right, but to match each product feature with the appropriate form of protection.
Including too many technical features in the description
Industrial design protection concerns appearance, not technical principles.
Filing raw engineering drawings
Engineering drawings often contain:
These should usually be reviewed and simplified before filing.
Inconsistent views
This can create serious uncertainty as to the subject matter for which protection is sought.
Registering the entire machine when only one component has meaningful design value
This may lead to an unnecessarily broad and less focused filing strategy.
Filing a component that is not suitable for separate protection
The legal and commercial suitability of the component should be assessed before filing.
Publicly disclosing the machine before filing
This may affect novelty.
Filing only an industrial design application without considering patent protection
Where the true commercial value lies in the machine's structure or operating principle, industrial design protection alone may be insufficient.
For a new machinery product, protection may be considered in several layers.
Layer 1 – Technical solution
Where the machine includes a new structure or operating principle:
Patent or utility solution.
Layer 2 – Overall external appearance
Where the machine has a new visual form:
Industrial design.
Layer 3 – Important component
Where a housing, module, assembly, or detachable part has independent design value:
Separate industrial design protection for the component.
Layer 4 – Product name and logo
Trademark registration.
Layer 5 – Control software
Copyright registration for the computer program, together with other protection where technical solutions are involved.
Layer 6 – Manufacturing know-how
Non-public manufacturing parameters, processes and know-how may be protected through:
Can industrial machinery be registered as an industrial design?
Yes, where the external appearance satisfies the statutory requirements.
If a machine is patented, is industrial design registration still useful?
Potentially yes. Patent protection covers technical solutions, while industrial design protection covers external appearance.
Can the machine housing be registered separately?
Potentially yes, provided that it qualifies as a protectable component and meets the applicable requirements.
Can an internal component be registered as an industrial design?
This depends on the circumstances. A shape that is not visible during normal use may fall outside the scope of industrial design protection.
Must technical dimensions be shown in the drawings?
Normally, industrial design drawings should focus on appearance and do not need engineering dimensions.
Can several machine models be included in one application?
Potentially, where they satisfy the unity requirements and qualify as acceptable variants. Materially different designs should generally be considered for separate applications.
Should the product be publicly disclosed before filing?
Preferably not. Filing before public disclosure is generally the safer approach for preserving novelty.
Is a prior search required?
It is not always mandatory, but it is highly recommended, particularly for products in fields with many existing similar designs.
Industrial design registration for machinery is often more complex than for simple consumer products because machinery may include multiple assemblies and components, with external design features closely intertwined with technical features.

Conclusion
For machinery and equipment, industrial design registration is an important tool for protecting the product's external appearance, but the application should be built around a carefully considered protection strategy.
Before filing, businesses should answer four key questions:
Which part of the machine has real design value?
Should the whole machine or only certain components be protected?
Do the drawings fully and consistently disclose the intended scope of protection?
Does the product also contain technical solutions that should be protected by patent or utility solution rights?
For machinery with significant technical and commercial value, an effective strategy often combines:
Patent/Utility Solution + Industrial Design + Trademark + Copyright/Trade Secret protection where appropriate.
Identifying these rights at the product development stage, before public disclosure and market launch, can significantly improve the scope and effectiveness of intellectual property protection.
