Patents in Indonesia: an overview for foreign businesses

Indonesia is the largest economy in South East Asia and an increasingly common filing destination for businesses expanding across the region. Its patent system is administered by the Directorate General of Intellectual Property (the DGIP), the national IP office under the relevant Indonesian government ministry, which can examine applications substantively before grant where the applicant takes the required steps. This page gives a practical overview of how patents work in Indonesia for businesses based elsewhere. It is general information rather than legal advice, and the specific steps for your situation are covered in our guide to filing a patent in Indonesia and in the wider Indonesia jurisdiction overview.

What a patent protects in Indonesia

An Indonesian patent protects an invention, broadly a technical solution to a problem in a field of technology. To be patentable, the invention must generally be novel (new against everything publicly available anywhere before the filing or priority date), it must involve an inventive step (it would not have been obvious to a person skilled in the field), and it must be capable of industrial application (it can be made or used in some kind of industry). These thresholds will be familiar from most major patent systems, though the DGIP applies them under its own law and examination practice, and certain subject matter is excluded or treated specially. If your invention sits in software, biotechnology, pharmaceuticals or methods, eligibility is jurisdiction-specific and worth checking with local counsel early rather than assuming it tracks how the same invention is treated at home.

Bahasa Indonesia is the filing language, and foreign applicants without a domicile in the country generally need to act through a registered local IP consultant who files and corresponds with the office on their behalf. This is a practical gateway requirement, so factor representation and translation into your planning from the outset.

The DGIP and the request for substantive examination

A point that surprises applicants from some other systems is that filing does not automatically put an application into substantive examination. You must file a separate request for substantive examination, and you must do so within a set period. If no request is filed within that period, the application can be deemed withdrawn, so the opportunity to obtain a patent on it is lost. The length of this request window and its precise consequences are statutory and change over time, so confirm the current period and the current fees with the DGIP or local counsel, and diarise the deadline as soon as you file rather than treating any particular timeframe as fixed.

Indonesia has continued to modernise its IP framework, and its patent procedure has been updated in recent regulatory reform, including changes affecting examination timeframes and certain filing formalities. Because the detail of how each procedure operates locally is precise and has changed, do not rely on older descriptions of the mechanics; confirm the current rules and any recent reforms with the DGIP or local counsel before you act.

First-to-file and the priority date

Indonesia is a first-to-file jurisdiction. Where two applicants file for the same invention, the earlier filing date prevails, regardless of who invented first. The practical consequence is the same everywhere first-to-file applies: file before you disclose, and file promptly, because public disclosure before your filing or priority date can destroy novelty. Indonesian law does recognise a limited grace period for certain disclosures connected to the applicant, but the conditions and the procedural steps to rely on it are specific, so do not treat it as a substitute for filing first; confirm the current rules with the DGIP or local counsel before disclosing anything.

If you are filing internationally, you will usually rely on a Paris Convention priority claim from your first application elsewhere, which lets you file in Indonesia while keeping your original date. That priority window is a statutory period and should be confirmed with the DGIP or local counsel rather than assumed.

The simple patent (paten sederhana)

Alongside the standard patent, Indonesia offers a simple patent (paten sederhana), its equivalent of the utility model found in many other countries. Broadly, a simple patent protects a new product or process that involves a development of an existing product or process, so it suits practical, incremental inventions that may not clear the inventive-step bar required for a standard patent. It is generally limited to a single invention, and the examination procedure differs from the standard patent: the request for substantive examination for a simple patent typically has to be made at filing or very shortly afterwards, rather than within the longer window that applies to a standard patent. Treat that timing as a confirm-with-counsel detail, because it is specific and consequential.

There is an important practical point for foreign applicants. A simple patent cannot be obtained through PCT national-phase entry, so if you are reaching Indonesia via the international route the simple patent is not on the table for that filing. The standard-versus-simple decision is therefore most relevant where you are filing directly, and whether a standard patent, a simple patent, or both is the right call is a genuinely fact-specific judgement. We explain the route in more detail in our guide to the simple patent in Indonesia.

Getting to Indonesia via the PCT national phase

Many foreign applicants reach Indonesia through the Patent Cooperation Treaty rather than by filing directly. You file a single international (PCT) application, then later enter the Indonesian national phase, where the DGIP examines the application under its own law. This route gives you more time before committing to country-specific costs and translation, and it lets you defer the decision on whether Indonesia is worth the spend. Indonesia is a designated office under the PCT, and national-phase entry has its own time limit, translation requirements (an Indonesian-language translation of the application) and formalities. We explain the international route in general in our overview of the PCT national phase.

Two things are worth flagging. First, national-phase entry deadlines are strict and counted from your priority date, and missing them generally forfeits the right to a patent in Indonesia. Second, entering the national phase is not the same as requesting substantive examination; that separate request step still applies, and a PCT national-phase entry leads to a standard patent rather than a simple patent. Treat the specific national-phase deadline, translation rules and the examination-request deadline as confirm-with-counsel details, because they are precise and consequential.

Patent term and maintenance annuities

An Indonesian patent runs for a defined term and is kept in force by paying periodic maintenance fees, known as annuities, throughout its life. Missing an annuity can cause the right to lapse, so diarising these payments is part of owning an Indonesian patent. One point is worth stating carefully. Under an older regime, Indonesia had a much-criticised problem in which unpaid annuities could continue to accrue as a debt to the office even after a patent had effectively lapsed, rather than the right simply ceasing cleanly. This was a real concern for foreign patent holders, and it was addressed by patent law reform, under which non-payment over the statutory period leads to the patent being cancelled rather than an open-ended debt building up. The treatment of any legacy patents, and the current mechanics of withdrawing or surrendering a patent, remain detailed, so confirm the position that applies to your specific patent with the DGIP or qualified local counsel before you stop paying or let a patent go. Official fees apply to filing, examination and annuities; confirm the current amounts with the DGIP or local counsel.

A note on using this information

This overview is general information about the Indonesian patent system and is not legal advice. IPEnvoy is not a law firm and does not provide legal advice. Patent law in Indonesia is detailed and changes, and the deadlines, terms, fees and ongoing reforms described here in general terms should be confirmed against the DGIP's official website or with a qualified local IP professional before you act. Where it helps, IPEnvoy can route you to vetted local counsel in Indonesia who can assess your specific position and handle filing, examination and enforcement.
