FAQ Patent Infringement in Indonesia: Clear Legal Answers for Businesses

If you are searching for faq patent infringement, you are probably dealing with something serious. Either someone is using your patented invention without permission, or you just received a warning letter and need to understand how exposed your business really is. Below are direct answers to the questions that usually come up in that situation.

This FAQ patent infringement overview addresses the legal risks and practical steps businesses need to understand under Indonesian law

What is considered patent infringement?

Patent infringement happens when someone uses, manufactures, sells, offers for sale, or imports a patented product or process without the patent holder’s consent.

It does not have to be a 100% copy. If the essential elements in your patent claims are being used, even with adjustments or modifications, it may still qualify as infringement.

This is not about similar branding or packaging. The real issue is whether the technical scope of the patent claims is being used without authorization.

What are the penalties for patent infringement in Indonesia?

Under Law No. 13 of 2016 on Patents, infringement carries legal consequences.

From a civil standpoint, a patent owner may seek:

• Financial compensation

• A court order to stop production or sales

• Seizure or destruction of infringing goods

In more serious cases — particularly where the infringement is intentional or commercially significant — criminal penalties may apply, including fines and imprisonment.

So this can move beyond a commercial dispute and enter criminal territory, depending on the circumstances.

How do I prove patent infringement?

This is where precision matters.

To establish infringement, you must generally show:

• You hold a valid patent.

• The accused product or process falls within the scope of your patent claims.

• You suffered measurable harm.

The core of the analysis is claim comparison. Each element of the patent claim is matched against the allegedly infringing product. If the essential elements are present, there may be infringement.

This is not something that should be assessed based on assumptions. It requires structured legal and technical review.

What should I do if someone infringes my patent?

The first step is not confrontation. It is assessment.

You should:

• Secure your patent certificate and registration documents.

• Gather evidence — product samples, advertisements, invoices, distribution records.

• Have the situation reviewed before sending any formal notice.

A cease-and-desist letter sent without proper analysis can weaken your position. In some cases, negotiation works. In others, filing a claim in the Commercial Court is necessary. The right move depends on your commercial objective and the scale of the infringement.

Can patent infringement be resolved without going to court?

Yes. Many disputes are resolved through negotiation.

Possible routes include:

• Settlement discussions

• Licensing arrangements

• Mediation

• Arbitration

Litigation becomes relevant when the other party refuses to cooperate or when urgent court intervention is required to stop ongoing losses. But not every infringement issue needs to escalate immediately.

How long does a patent last in Indonesia?

A standard patent is valid for 20 years from the filing date.
A simple patent (utility model) is valid for 10 years.

Once the protection period ends, the invention enters the public domain and can no longer be enforced.

Can I accidentally infringe someone’s patent?

Yes, and this happens more often than expected.

Indonesia applies a first-to-file system. Even if you developed a product independently, you may still infringe if another party registered the invention earlier.

That is why clearance searches are important before launching a product, starting manufacturing, or importing technical goods into Indonesia.

What if I am accused of patent infringement?

Do not ignore the allegation.

You may have defenses, such as:

• Your product does not fall within the patent claims

• The patent is invalid

• The patent has expired

• You are operating under a valid license

But how you respond matters. An unstructured reply or silence can increase legal and financial risk. A measured legal response protects your position.

When should I consult a patent lawyer?

You should seek advice if:

• You receive a warning letter

• You suspect your invention is being copied

• You are preparing to commercialize a technical product

• You are entering licensing negotiations

Early evaluation often prevents larger disputes later.
