WHAT IS THE DIFFERENCE BETWEEN AN INVENTION PATENT AND A UTILITY SOLUTION?

INTELLECTUAL PROPERTY

Under Vietnamese intellectual property law, both inventions and utility solutions are protected through exclusive protection titles granted by the Intellectual Property Office of Vietnam (IP Vietnam). However, these two forms of protection differ significantly in terms of protection requirements, protection duration, and practical application scope.

What Are an Invention Patent and a Utility Solution?

In research, manufacturing, and technological innovation activities, many businesses and individuals often wonder whether they should register an invention patent or a utility solution to protect their technical achievements.

Choosing the appropriate form of registration from the beginning plays an important role in the possibility of obtaining protection and the future commercialization strategy.

What Is an Invention?

An invention is a technical solution in the form of a product or a process intended to solve a specific problem by applying natural laws.

Under Vietnamese Intellectual Property Law, an invention is protected in the form of an Invention Patent if it satisfies all of the following conditions:

  • Novelty;
  • Inventive step;
  • Industrial applicability.

Generally, inventions involve a higher degree of technical innovation and breakthrough compared to utility solutions.

What Is a Utility Solution?

A utility solution is also a technical solution in the form of a product or process intended to solve a specific problem.

However, unlike inventions, utility solutions are not required to satisfy the same high inventive step requirement.

To be protected under a Utility Solution Patent, the subject matter must satisfy:

  • Novelty;
  • Industrial applicability;
  • Not being common knowledge.

Due to lower protection requirements, utility solutions are often suitable for:

  • technical improvements;
  • product improvements;
  • equipment improvements;
  • manufacturing process improvements;
  • technical solutions with high practical applicability.

Similarities Between Inventions and Utility Solutions

Although there are certain differences, inventions and utility solutions still share several similarities.

Both Are Technical Solutions

Both must be technical solutions intended to solve a specific problem by applying natural laws.

Both Are Protected by IP Vietnam

Once the protection requirements are satisfied, the applicant may be granted:

  • an Invention Patent; or
  • a Utility Solution Patent.

Both Must Be Novel

The subject matter must not have been publicly disclosed before the filing date or priority date.

This is a very important requirement in the protection process.

Both Must Have Industrial Applicability

The technical solution must be capable of:

  • manufacturing;
  • production;
  • repeated application;
  • generating stable and consistent results in practice.

What Is the Difference Between an Invention Patent and a Utility Solution?

Below are the key differences between inventions and utility solutions under Vietnamese intellectual property law.

Difference in Inventive Step

Invention

An invention must involve an inventive step.

This means the technical solution must not be obvious to a person having ordinary skill in the relevant technical field.

This is a relatively high requirement and is one of the primary reasons why many patent applications are rejected.

Utility Solution

A utility solution does not require the same high level of inventive step as an invention.

The solution only needs to:

  • not be common knowledge;
  • involve improvement;
  • have practical applicability.

Therefore, many minor technical improvements may still be protected as utility solutions.

Difference in Protection Duration

Invention Patent

Valid for:

  • 20 years from the filing date.

Utility Solution Patent

Valid for:

  • 10 years from the filing date.

Difference in Level of Technical Innovation

Invention

Usually involves:

  • breakthroughs;
  • high creativity;
  • significant technical advancement.

Examples include:

  • new AI technologies;
  • new medical devices;
  • entirely new manufacturing processes.

Utility Solution

Usually involves:

  • technical improvements;
  • structural improvements;
  • optimization of existing processes or equipment.

Examples include:

  • improved machine structures;
  • improved manufacturing tools;
  • optimized operating systems.

Difference in Possibility of Obtaining Protection

In practice, utility solutions often have a higher chance of obtaining protection because the protection requirements are lower than those for inventions.

In many cases:

  • the subject matter may not qualify for an invention patent;
  • but may still be protected as a utility solution.

This is a strategy commonly used by businesses to increase the possibility of protecting technical innovations.

Should You Register an Invention Patent or a Utility Solution?

The choice depends on:

  • the level of technical innovation;
  • commercial objectives;
  • protection strategy;
  • ability to satisfy legal requirements.

You Should Register an Invention Patent When:

  • The solution has a high level of innovation;
  • It involves breakthrough technology;
  • There is a long-term commercialization strategy;
  • The invention has significant commercial value;
  • There are plans for international protection.

You Should Register a Utility Solution When:

  • The solution mainly involves technical improvements;
  • It may be difficult to satisfy the inventive step requirement;
  • You want to increase the likelihood of obtaining protection;
  • You want to save processing time and costs.

Can an Application Be Converted Between an Invention Patent and a Utility Solution?

Under Vietnamese intellectual property law, in certain cases, applicants may:

  • convert an invention application into a utility solution application; or
  • vice versa,

provided that the legal requirements are satisfied.

This is a practical solution to reduce the risk of rejection during substantive examination.

Common Mistakes When Choosing the Protection Form

Many businesses encounter difficulties because they:

  • incorrectly assess the inventive level;
  • choose the wrong protection form;
  • fail to conduct prior searches;
  • disclose the solution too early;
  • fail to establish an appropriate protection strategy.

Early legal consultation can significantly increase the likelihood of obtaining protection.

Frequently Asked Questions

Is a Utility Solution Considered an Invention?

A utility solution is also a technical solution but has lower protection requirements compared to an invention.

Does a Utility Solution Enjoy Exclusive Protection?

Yes. Once granted, the owner has exclusive rights to exploit and use the utility solution.

What Is the Protection Term for a Utility Solution?

10 years from the filing date.

If an Invention Does Not Satisfy Patentability Requirements, Can It Be Registered as a Utility Solution?

In many cases, the application may be converted into a utility solution application to increase the possibility of obtaining protection.

Is Registering a Utility Solution Easier Than Registering an Invention?

Generally, the likelihood of obtaining protection is higher because the inventive step requirement is lower.
