Indonesia’s innovation economy is expanding quickly, and intellectual property is now an important part of the conversation. Foreign companies bringing new technology, products or manufacturing processes into the country are increasingly treating patent registration as one of the first legal steps to take before entering the market, rather than as an afterthought once a product is already on sale. Without a registered patent, years of development work on an invention can be undone if it is copied, manufactured, or distributed locally with little recourse. This guide explains how the patent registration process works under Indonesia’s current framework, what foreign innovators need to prepare, and where people most often encounter difficulties.
Why Patent Protection Matters Before Entering the Indonesian Market
Indonesia is Southeast Asia’s largest economy, and patent filings have been climbing steadily as more industries move into research-driven products. Applications in information technology, electronics, communications, and biomedicine have grown the fastest, reflecting how much local manufacturing and R&D activity now touches patentable technology (data from Indonesia’s own IP office, cited in Viet An Law’s overview of the filing process, shows applications rising year over year). For a foreign innovator, that growth cuts both ways: it signals a receptive market, but also a growing number of local players capable of reverse-engineering an unprotected product. Registering a patent before signing a distribution agreement, opening a manufacturing line, or entering a joint venture gives a company something concrete to enforce if a partner or competitor oversteps the terms of the relationship.
Indonesia’s Legal Framework for Patents
Patent protection in Indonesia sits under Law No. 13 of 2016 on Patents, as amended by Law No. 65 of 2024. The implementing rules were refreshed through Minister of Law Regulation No. 6 of 2026 on Patent Applications, which took effect on 23 February 2026 and replaced the older Regulation No. 38 of 2018. The update did more than tidy up paperwork: it broadened what counts as a patentable invention, adding systems, methods, and utilisations to the existing categories of products and processes, and it introduced mandatory electronic filing through the Directorate General of Intellectual Property, known locally as DGIP (Tilleke & Gibbins’ summary of the new regulation and Spruson & Ferguson’s analysis of the procedural changes both go through the changes in detail). Indonesia is also a member of the Patent Cooperation Treaty, and the WTO’s TRIPS Agreement, so its minimum standards of protection are meant to align with international practice, even where local procedure has its own rhythm
Standard Patents vs. Simple Patents: Choosing the Right Protection
Indonesia recognizes two tiers of protection, and choosing the right one shapes both the cost and the timeline of patent registration. A standard patent covers genuinely new inventions with an inventive step and runs for 20 years from the filing date. A simple patent, closer to what other jurisdictions call a utility model, covers a single invention that is new and has practical application, without needing to clear the higher bar of an inventive step. It runs for 10 years and tends to move through examination faster. Manufacturing-heavy businesses making incremental improvements to existing products, rather than breakthrough inventions, often find the simple patent route a more practical fit.
The Patent Registration Process
The process for foreign applicants follows a fairly consistent sequence, though the exact timing has shifted under the 2026 rules.
1. Prior art and novelty search. Before drafting anything, check DGIP’s patent database and relevant international databases to confirm the invention is genuinely new. This also helps shape how the claims are drafted later.
2. Appoint a registered Indonesian patent agent. Foreign applicants cannot file directly. Indonesian law requires a registered local IP consultant to act as agent before DGIP, so this is typically the first practical step rather than a formality tacked on at the end.
3. Prepare and file the application electronically. The filing includes the specification, claims, abstract, and drawings where relevant. If the original documents are in English, an Indonesian translation must follow within one month of the filing date.
4. Publication. Applications are published after 18 months as standard, though the 2026 regulation allows applicants to request accelerated publication within three months of filing for an additional fee, useful when speed matters commercially.
5. Request substantive examination. This can now be filed early, even before publication closes, rather than only after the standard publication window ends, which shortens the practical path to a decision for applicants who choose that option.
6. Examination and decision. DGIP must decide within 30 months of the examination request, or 30 months from the end of the publication period if examination was requested early. Complex mechanical, chemical, or software-related inventions tend to sit toward the longer end of that window.
7. Grant, certificate, and post-grant duties. Once granted, the patent holder receives an official certificate. Indonesia also expects patent holders to file periodic reports on how the invention is being worked or used in the country, a compliance step that foreign applicants sometimes overlook.
Filing Directly vs. Entering Through the PCT
Foreign innovators generally choose between two filing routes. A direct national filing at DGIP is the simpler option when Indonesia is the only market being pursued. For companies protecting an invention across several countries, entering through the Patent Cooperation Treaty lets them file one international application first and decide later, country by country, where to commit to local costs and translation. Entering the Indonesian national phase still requires a local agent, an Indonesian translation of the specification, and payment of national fees within the applicable deadline, so the WIPO PCT Applicant’s Guide is worth checking early, since national phase deadlines are strict and jurisdiction-specific.
If an Application Is Refused: Re-Examination and Appeal
Refusal is not necessarily the end of the road. Under the current framework, an applicant can request substantive re-examination within nine months of a refusal notice. If that route does not resolve the issue, an appeal can be filed with the Patent Appeal Commission, again within nine months of the decision, and from there, a further appeal to the Commercial Court is available within three months of the Commission’s ruling (Spruson & Ferguson’s breakdown of the appeal timeline sets out each stage in sequence). Knowing these windows in advance matters, since missing a deadline by even a few days can close off an otherwise viable challenge.
Common Mistakes Foreign Innovators Make
• Disclosing the invention publicly, at a trade show or in a press release, before filing, which can undermine the novelty requirement.
• Treating the Indonesian translation as a routine formality rather than reviewing it against the original claims for accuracy.
• Underestimating the compliance side after grant, particularly the requirement to report how the patent is being used locally.
• Choosing between a standard and simple patent based on cost alone, without weighing which term length and examination path actually fits the product’s commercial life.
• Assuming a PCT filing automatically extends protection to Indonesia without completing the national phase entry and its deadlines.
