How to File a Patent in Indonesia with the DGIP

Filing a patent in Indonesia means dealing with the Directorate General of Intellectual Property (DGIP, the Direktorat Jenderal Kekayaan Intelektual), the national IP office under Indonesia's Ministry of Law and Human Rights. The process will feel broadly familiar to anyone who has filed elsewhere, but Indonesia has several features that catch foreign applicants out: it is strictly first-to-file, applications are filed and examined in Bahasa Indonesia, foreign applicants without an Indonesian domicile must act through a registered local IP consultant, substantive examination is a separate request rather than automatic, and the annuity system has a known history that has since been the subject of legal change. This guide walks through the route from filing to grant, the simple patent alternative, and the two main ways foreign applicants reach Indonesia: the Patent Cooperation Treaty (PCT) national phase and the Paris Convention priority route.

This is general information rather than legal advice. Indonesian patent practice is procedural and unforgiving on deadlines, and foreign applicants act through a registered Indonesian IP consultant. Treat the timelines below as orientation and confirm the current periods and fees with the DGIP or local counsel before you act. For the wider picture of protecting an invention in Indonesia, see our Indonesia patents overview.

What you can protect, and the core requirements

Indonesia grants patents for inventions, broadly the solution of a technical problem in the form of a product or a process. To be patentable, an invention generally needs to be new, to involve an inventive step, and to be capable of industrial application, which the DGIP assesses during examination.

Novelty is assessed against the state of the art before the filing date, or the priority date if priority is claimed. Indonesia applies a strict novelty standard, so a public disclosure you made yourself can count against you. A grace period exists for specified disclosures, but its scope and conditions are narrow and easy to misjudge, so confirm the current position with counsel rather than rely on it. Inventive step asks whether the invention would have been obvious to a person skilled in the relevant field, and is usually the requirement that decides whether a patent is granted. Industrial applicability asks whether the invention can be made or used in industry.

Certain subject matter is excluded from patent protection in Indonesia, and the boundaries are jurisdiction-specific and have changed over time, so which right fits your situation is a point to discuss with counsel. Patents are not the only route: some outputs, such as software code and written or artistic works, are protected by copyright without registration, and Indonesia additionally offers a voluntary copyright recordal (pencatatan) at the DGIP that many rights holders use as evidence of authorship. That is a separate mechanism from the patent route, so do not assume patents are the only way to protect a given output.

First-to-file: the date is everything

Indonesia is a first-to-file jurisdiction. Where two applicants independently reach the same invention, the one who files first at the DGIP has priority, regardless of who invented it first. There is no general mechanism for a later inventor to displace an earlier filer by proving earlier invention.

The practical consequence is simple: file early, and file before you disclose. This matters especially in Indonesia, where bad-faith filing is a real and well-documented risk for foreign brands and, in some cases, technologies. The safest course is to secure your priority date early and not to publish before filing.

Filing language, the local consultant and translation practice

An Indonesian patent application is filed and examined in Bahasa Indonesia, including the description, claims and abstract, with any drawings. Foreign applicants therefore need a careful Bahasa Indonesia translation, and translation quality matters: ambiguities or errors introduced in translation can narrow your claims or create objections that are awkward to fix later, because amendments cannot add new matter beyond the original disclosure.

A foreign applicant with no residence or place of business in Indonesia must, as a matter of Indonesian practice, appoint a registered local IP consultant to file and conduct proceedings before the DGIP and to receive official correspondence. This is a procedural requirement, not merely a convenience, so engage a consultant early. Indonesia does provide a mechanism that lets you secure a filing date and submit the Bahasa Indonesia translation within a prescribed later period, but the availability and exact deadlines are specific and have changed over time, so treat this as a confirm-with-counsel point rather than a fixed rule.

Filing the application

A complete Indonesian patent application generally comprises a request identifying the applicant and inventors, the description, the claims, an abstract, and any drawings, together with priority documents where priority is claimed. The specification must disclose the invention clearly and completely enough for a skilled person to carry it out, and the claims, which define the scope of protection, must be supported by the description. Weak disclosure or unclear claims are common grounds for objection.

On filing you pay official fees, and the cost of obtaining an Indonesian patent is driven by several factors rather than a single number: the official filing fee, the separate examination-request fee discussed below, the cost of translation into Bahasa Indonesia, consultant fees, the number of claims, and annuity fees once the patent is in force. Official fees apply, so confirm the current amount with the DGIP or local counsel rather than relying on any figure quoted second-hand.

The separate request for substantive examination

Filing an application at the DGIP does not by itself put it into substantive examination. Indonesian practice requires a separate request for substantive examination, with its own fee, made within a prescribed period. If the request is not filed within the applicable window, the application can be treated as withdrawn and the opportunity to obtain a patent lost. The timing of the examination request differs depending on whether you filed directly under the national route or entered via the PCT national phase, so there is no single period that covers both. Because this is among the most dangerous deadlines in the Indonesian process, do not rely on a remembered figure: confirm the exact trigger and window for your route with the DGIP or your Indonesian consultant and diary it carefully.

Publication, examination, objections and grant

Indonesian applications are published, which opens an announcement period during which third parties may file observations or objections that the examiner can take into account. This is a third-party observation mechanism rather than a formal inter-partes opposition of the kind seen in trade mark practice, so confirm how it operates with counsel. Once substantive examination has been requested, a DGIP examiner reviews the application against the patentability requirements and for formal and clarity issues. If the examiner identifies problems, the DGIP issues objections to which the applicant can respond by argument and by amending the claims or description, within the limits on adding new matter.

If the examiner is satisfied, the DGIP issues a decision to grant and the patent is registered and published. If a refusal is maintained, the applicant can pursue the available appeal routes. The patent term in Indonesia runs from the filing date for a defined number of years, subject to payment of annuities, and a simple patent carries a shorter term than a standard patent. Treat the exact terms and the relevant periods as confirm-with-counsel, since they are statute-specific.

Grant, annuities and the accrued-annuity history

Keeping an Indonesian patent in force requires payment of annual maintenance fees (annuities). Indonesia has a known history in which holders who stopped paying or who failed to surrender a patent properly found that annuity liability continued to accrue, leaving an outstanding debt even after the patent had effectively lapsed. The rules around how a patent is treated as deemed void for non-payment, and whether accrued annuities can still be claimed as a debt, have since been the subject of legal change and clarification, so this is an area to handle with particular care rather than to assume reflects the current position. Official fees apply and the current treatment of lapse and accrued annuities should be confirmed with the DGIP or local counsel before you decide to stop maintaining a patent; do not simply stop paying and assume the liability ends.

The simple patent alternative

Indonesia offers a simple patent (paten sederhana), its utility-model equivalent, as a faster, lighter route for certain inventions, typically a product or process that is new and capable of industrial application. Unlike a standard patent, a simple patent requires novelty and industrial applicability but is not assessed for inventive step in the way a standard patent is, which is why it suits incremental improvements or short-lifecycle products. Simple patents were historically limited to a single claim and have a shorter term and a lighter examination path; the claim rules have changed over time, so confirm the current claim limits, scope and term with counsel rather than assume a single-claim limit still applies. A simple patent is a considered choice rather than a default. Our simple patent guide covers the trade-offs and how a simple patent sits alongside the standard patent route.

Reaching Indonesia from abroad: PCT and Paris priority

Most foreign applicants reach Indonesia by one of two international routes, and the choice usually depends on how many countries you are targeting and your timing.

The PCT national-phase route is common where you want protection in several countries. You file a single international application under the PCT, which preserves an effective filing date across member states, then later enter the national phase in each country you choose, including Indonesia, by meeting that country's requirements (translation into Bahasa Indonesia, national fees and local formalities) within the prescribed national-phase deadline. Entering the Indonesian national phase still requires a separate request for examination, and the trigger and window for that request can differ from the ordinary national route, so the examination deadline does not disappear simply because you arrived via the PCT; confirm the applicable period with counsel. For how the international system works generally, see our PCT guide.

The Paris Convention priority route suits applicants filing directly in a smaller number of countries. If you file a first application in one Paris Convention country, you can file a corresponding application in Indonesia within the Paris priority period (commonly twelve months for patents, but confirm the current period and its calculation with the DGIP or counsel) and have the Indonesian application treated, for the purpose of assessing prior art and intervening filings, as if filed on your original priority date. The two routes are not mutually exclusive; a PCT application itself commonly claims Paris priority from an earlier national filing.

A practical sequence

The following summarises the typical order of events for a foreign applicant. The exact periods are statute-specific and should be confirmed with the DGIP or counsel.

Where to get this right

Indonesian patent prosecution rewards early filing, accurate Bahasa Indonesia drafting through a registered consultant, and disciplined diary management of two deadlines in particular: the priority or national-phase entry deadline, and the separate request for substantive examination, whose timing depends on your route. Annuity management deserves equal care given the accrued-liability history.
