Myanmar’s Trademark Law 2019 introduced a modern framework for the registration, enforcement, and protection of trademarks. However, due to the high volume of applications filed during the soft-opening period of the Intellectual Property Department (IPD), marks submitted from 2022 onward remain pending as the IPD works its way through the applications filed in 2021, which it has been publishing on a monthly basis since May 1, 2024. During this period, businesses should adopt proactive strategies to protect their brands, monitor conflicting marks, and ensure a smooth registration process. Practical Steps for Safeguarding Pending Marks While a pending application does not confer full trademark rights, brand owners can take several practical steps to strengthen their position: Monitor IPD publications. Businesses should regularly review the IPD’s monthly gazette to identify any identical or confusingly similar marks at an early stage and prepare timely oppositions in accordance with the Trademark Law’s provisions allowing “any interested party” to file an objection to a trademark application. Monitor market activity. Early detection of potential infringement enables swift action, such as cease-and-desist letters and opposition proceedings. Businesses should monitor competitors, distributors, and retailers for unauthorized use of their marks. Collect evidence of use. Maintaining evidence of use strengthens claims of distinctiveness and supports enforcement efforts. Businesses should keep records of commercial activities, distribution, brand promotion and development, marketing communications, product packaging and labeling, and sales demonstrating brand recognition in Myanmar and internationally, particularly in Southeast Asian markets. Although the Trademark Law 2019 establishes a first-to-file system, evidence of use provides considerable practical support for distinctiveness claims and enforcement actions. Pursue Interim Enforcement Options. A pending trademark application can be relied upon to oppose or refuse other marks on absolute and/or relative grounds of refusal. In addition, marks with established reputations may be protected under passing-off principles

On January 26, 2026, Vietnam’s Ministry of Finance issued Circular No. 06/2026/TT-BTC (Circular 06), amending and supplementing Circular No. 13/2015/TT-BTC, which provides guidance on dossiers and procedures for customs recordal and customs supervision in relation to intellectual property rights (IPR). Circular 06 has an effective date of March 1, 2026. Some notable points of Circular 06 include the following: Simplified Documentation for Customs Recordal Applications Circular 06 reduces some documentary requirements for IPR owners: A power of attorney is no longer required to be legalized. Applicants are no longer required to submit title or registration certificates if such documents are issued in digital form. In such cases, it is sufficient to declare comprehensive information on the relevant IPR, enabling customs authorities to verify the information through publicly accessible databases. In practice, this amendment is particularly beneficial for international trademark registrations designating Vietnam. IPR owners may no longer need to obtain a confirmation letter from the Intellectual Property Office of Vietnam regarding the validity of a trademark registration in Vietnam. Instead, they may rely on registration status information available from the World Intellectual Property Organization (WIPO) database, reflecting that the international registration has been granted protection in Vietnam. Clearer Mechanism for Ex Officio Suspension of Suspected Infringing Goods Although ex officio suspension has been referenced in earlier regulations, Circular 06 provides clearer guidance on the circumstances and procedures under which customs may proactively suspend customs procedures for consignments suspected of being counterfeit or pirated goods. Accordingly, customs authorities may initiate the suspension of clearance without waiting for a formal request from IPR owners. Enhanced Supervision of Imported/Exported Goods in E-Commerce Circular 06 also supplements provisions on the inspection of imported and exported goods transacted through e-commerce channels. Customs authorities may apply risk management measures to assess goods traded via e-commerce

Thailand is preparing to offer new tools for intellectual property enforcement as the Electronic Transactions Development Agency (ETDA) recently released for public consultation a draft notification requiring social media platforms to verify user identities and conduct know-your-customer (KYC) checks on advertisers. The draft Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers, which is to be issued under the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes B.E. 2566 (2023), as amended in 2025, primarily aims to combat online fraud and technology-related crimes. However, its new obligations also provide IP owners with valuable tools to identify anonymous infringers. Key Regulatory Mandates The draft notification imposes several verification requirements on social media platforms operating in Thailand. These requirements also strengthen IP rights holders’ ability to identify anonymous infringers, as platforms must: Verify user identities through registered phone numbers and link all accounts to verifiable identities. Conduct KYC checks on advertisers, including individuals, companies, and any third-party payers. Perform heightened identity checks for high-risk or repeat offenders before publishing advertisements. Promptly remove content flagged by the Anti-Technology Crime Division and prescreen advertisements for prohibited or high-risk content. How IP Owners Can Use This Notification for Enforcement The phone number–based verification requirement enables IP owners to work more effectively with enforcement authorities in tracing individuals or entities responsible for infringing content. The comprehensive advertiser KYC obligations, including mandatory disclosure of third-party payment sources, create a clear audit trail even when bad actors attempt to obscure their identity through intermediaries or shell accounts. This traceability is essential for pursuing damages and dismantling organized counterfeit operations. The ETDA is now considering adjustments to the draft notification after receiving comments during the public consultation period, which ended on February 2, 2026. Following finalization
