Indonesia’s Ministry of Law has introduced a new framework for patent applications that tightens filing requirements and introduces formal mechanisms for accelerated examination. Minister of Law Regulation No. 6 of 2026 on Patent Applications, which was issued on January 13, 2026, and took effect on February 23, 2026, serves as the implementing regulation for Law No. 65 of 2024 on Patents. It replaces the previous patent application framework (under Minister of Law and Human Rights Regulation No. 38 of 2018, as amended by Regulation No. 13 of 2021), which was considered no longer aligned with current legal, institutional, and technological developments. The regulation also reflects the institutional restructuring of the Ministry of Law and Human Rights into the Ministry of Law. Patent applications filed on or after February 23, 2026, must fully comply with the new regulation. Applications that were filed before this date will continue to be examined and processed under the previous regulation, pursuant to transitional provisions. Substantive Changes Definition of Invention The definition of “Invention” now explicitly includes systems, methods, and uses, in addition to products and processes. This expansion creates broader protection opportunities, particularly for software-enabled, digital, and method-based technologies, although it may also result in closer scrutiny during substantive examination. Excess Claims Fee Excess claims fees must now be paid at the time of filing. Failure to pay excess claims fees at filing results in the application being deemed withdrawn. There is no longer an option to defer payment to the substantive examination stage. This amendment forces applicants to face higher upfront costs. Patent claim strategy must be finalized prior to filing, reducing flexibility at later stages. Procedural and System Changes Fully Electronic Filing Patent applications must be filed electronically via the Directorate General of Intellectual Property (DGIP) online filing system. Assisted filings to

Indonesia’s Directorate General of Intellectual Property (DGIP) has introduced a temporary feature in its online filing system to accommodate the submission of annual patent working statements. The requirement to submit these annual working statements was introduced under the amended Patent Law enacted on October 28, 2024, but the implementing regulation has still not been issued. Annual Working Statements Article 20A of the amended Patent Law requires all patentees to submit an annual statement regarding the implementation of their patents in Indonesia. This obligation applies to all active patents, regardless of when they were granted. The annual working statement declares the status of implementation of the patented invention within Indonesia. Acceptable forms of implementation include: Manufacturing the patented product (whether commercialized or not) Utilizing the patented process (whether commercialized or not) Importation Licensing If the patent has not yet been implemented in Indonesia, the DGIP provides an option to indicate: “The mentioned registered patent has not been implemented in Indonesia.” The statement must be made using the official template provided by the DGIP through the online filing system. Submission The working statement must be submitted annually no later than December 31 of each calendar year. No supporting documents are needed for the submission apart from the signed form itself. A color scanned copy will suffice; the original document is not required. There is currently no official fee for submitting the working statement. While the submission process may eventually align with annuity fee payments, the current process remains separate due to the pending implementing regulation. The submission process may be subject to change upon issuance of the implementing regulation, which is under discussion and expected in the coming months. In the interim, the DGIP accepts submissions of overdue working statements, allowing patentees to fulfill their obligations retroactively. This flexibility is expected

On October 28, 2024, Indonesia officially amended its existing Patent Law when the president ratified Law Number 65 of 2024. This comprehensive update—the third such amendment in the history of Indonesia’s Patent Law—introduces several key changes that will significantly impact patent protection and application processes in Indonesia. Key highlights and changes are outlined below. Definition of Invention The new law broadens the definition of “invention” to explicitly include systems, methods, and uses. Additionally, the law introduces formal definitions for traditional knowledge and genetic resources. Patentability Criteria Notable changes include: Computer programs are now excluded, with an exception for computer-implemented inventions. Theories and methods in science and mathematics are added to the list of excluded inventions. Previous restrictions on new uses of existing products are removed. Grace Periods The grace periods for some patent-related actions have been adjusted: The grace period for disclosures has been extended to 12 months (from 6 months previously), providing inventors with more flexibility in filing patent applications after initial disclosure. A newly introduced item is the grace period for a conventional patent application claiming priority rights, which is 4 months after the 12-month filing deadline under the Paris Convention. The grace period for annuity payments is 6 months (from 12 months previously) with a fine for late payments of 100% of the annual fee payable. Patent Holder Rights and Obligations Patent holders can now grant permissions to enforce patents. There is a new requirement for patent holders to submit annual statements on patent implementation in Indonesia. Compulsory Licensing Significant changes to compulsory licensing include: Establishment of licenses based on the principle of expediency. Limitations on license scope and transferability. Prioritization of domestic market needs. New provisions for technical improvements and economic significance. Government Patent Exploitation The new law contains specific provisions for the government’s implementation

On November 13, 2023, the Directorate General of Intellectual Property (DGIP) of Indonesia’s Ministry of Law and Human Rights held an offline workshop regarding intellectual property (IP).  One of the main discussion topics was the socialization of the proposed amendments to the Industrial Design Law. The proposed amendments to the Industrial Design Law contain a number of important changes, as outlined below. Industrial design definition The definition of an industrial design is clarified and emphasized in the draft law. An object protected through industrial design rights is “the outer appearance of a product,” gives an “aesthetic impression,” can be protected in whole or in part, and may be two- or three-dimensional. Registration system The protection period for industrial designs set by the draft law is 5 years, renewable for up to two additional five-year terms. This differs from the period provided under the current law, which is 10 years from the filing date, nonrenewable. Recordal system The draft law introduces a recordal system particularly for designs that have a relatively short commercial turnaround time, such as textile products. Recorded designs have a protection period of three years from the first publication. The recorded designs can become registered design applications by filing the design through the DGIP’s registration system no later than 12 months from its first publication. Details regarding the recordal system are not yet available. Nonregistrable industrial designs The draft law clarifies that the following are not registrable as industrial designs: Designs that do not give an aesthetic impression; Designs whose features are for purposes of technical functioning only; Folklore or traditional cultural expressions that have not been developed further; Designs contrary to the provisions of laws and regulations, public order, religion, or morality; and Designs filed in bad faith. International design applications The new law introduces a
