In addition, she supervises the preparation of trademark applications, registrations, and renewals, and coordinates enforcement strategies to protect brand owners’ interests.

Before moving to head up the firm’s Indonesia office, Wongrat worked as an attorney-at-law in the firm’s head office in Bangkok for several years. Wongrat is admitted to the bar in Connecticut and Massachusetts and is qualified as a Thai patent agent.

Indonesia has updated its fee framework for intellectual property (IP)-related government services, with implications for IP owners, licensees, lenders, digital platforms, and businesses operating in the country. Government Regulation No. 30 of 2026 on Types and Tariffs of Non-Tax State Revenue Applicable to the Ministry of Law (GR 30/2026) was promulgated on July 2, 2026, and will take effect on August 1, 2026. Key Takeaways GR 30/2026, which replaces the relevant IP service fees under Government Regulation No. 45 of 2024, reorganizes the fee schedule into separate categories for copyright, industrial designs, patents, layout designs of integrated circuits, trade secrets, trademarks, geographical indications, IP enforcement, and other categories. The most commercially relevant changes include a new copyright recordation tariff exemption for songs and music, higher fees for several trademark and geographical indication services, new IP enforcement service fees, and a new fee type for registration of fiduciary security over IP rights objects. In addition, this is the first major update for trademark fees in approximately 10 years. GR 30/2026 is significant not only as a fee update but also as a further indication of Indonesia’s increasing recognition of IP as a financeable commercial asset. By expressly assigning fees to the registration of fiduciary security over IP rights objects, the regulation places IP-backed collateral filings within the Ministry of Law’s administrative service framework. While GR 30/2026 does not create a new secured-transactions regime, this development is relevant for lenders, borrowers, and IP owners structuring financing arrangements secured by trademarks, patents, copyrights, industrial designs, or other registrable IP rights in Indonesia. Copyright: New Fee Exemption for Songs and Music Recordation For copyright, GR 30/2026 creates a fee-exempt category for recordation of works or related-rights products for songs or music, while maintaining a separate category for other works and related-rights products. It

Indonesia’s regulation on reporting online intellectual property (IP) infringement provides comprehensive procedural guidance for IP rights holders and their licensees in reporting online infringement complaints. Issued in December 2025 by the Ministry of Law as Regulation No. 47 of 2025 regarding Handling of Intellectual Property Infringement Reports in Electronic Systems, this regulation covers all types of IP rights. It also specifies documentation when reporting infringement, and lays out the procedures for examination, verification, and enforcement actions. Submission of Complaints Complainants may submit reports through the online system of the Directorate General of Intellectual Property (DGIP) or in person at the DGIP office. Complaints may also be filed through an authorized proxy. Under the regulation, complainants are required to provide the following information and documents: Personal details of the complainant; Brief description of the protected work or subject matter (i.e., type of IP and name or address of the infringing website, portal, account, or application, or a link to the location of the infringing content); Complete description of the alleged infringement; Certificate of registration or recordal of the relevant IP; Recordal of IP license agreement, if any; and Other supporting evidence. Verification and Examination Process Upon receiving a complaint, the responsible formality officer may request clarification or additional supporting documents. In the latter case, the complainant must then submit the necessary administrative documents within 14 days of the notification date. Once the documentation is deemed complete and sufficient, the case will be formally registered. Subsequently, the DGIP will establish a verification team to handle online IP violations, which will include the Civil Servant Investigator (PPNS), the Ministry of Communication and Digital Affairs, experts with relevant expertise in IP, and representatives from related associations such as AVISI (Indonesian Video Streaming Association). After examining the report, the team will prepare the Minutes

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 trademark prosecution process has been significantly streamlined with Ministry of Law Regulation No. 5 of 2026 (MOLR 5/2026) coming into effect on February 23, 2026. In straightforward cases without opposition, applicants may now see their trademarks proceed to registration within three months from filing—a substantial improvement over previous practice. The regulation also introduces detailed procedures for recording changes of name and address and for transferring rights over pending applications. It enhances the role of the Ministry of Law’s regional offices in assisting local individuals and SMEs, adds provisions governing force majeure situations, implements new requirements for collective trademarks, and formalizes several practices already in place. Substantive Examination Acceleration The most significant change under MOLR 5/2026 concerns substantive examination. The regulation now explicitly requires that applications be published within 15 days of filing, followed by a two-month publication period. Oppositions must be filed only within this window; late submissions will not be processed, even if the system accepts payment. The new regulation requires the Trademark Office (TMO) to forward copies of any opposition to applicants within 14 days of receipt. If no opposition is filed, substantive examination begins immediately after the publication period ends and will be completed within 30 days. If an opposition is filed, the examination is to be finalized within 90 days of the counterstatement filing date. These timelines enable unopposed applications to move from close of publication to final decision in roughly one month. If an application is provisionally refused during ex officio examination, the applicant has 30 working days from the date of notification to file a response. However, the regulation does not specify the timeline for subsequent reexamination after the response is filed. In recent practice, the TMO has been completing reexamination within approximately two to three months. Ownership Recordals May Pause Substantive
