The Intellectual Property Office of Vietnam (IP Office), with support from the Japan International Cooperation Agency (JICA), is drafting additional annexes to its Guidelines for Patent Examination, focusing on the examination of patent applications in the pharmaceutical and biotechnology sectors. The new annexes are expected to be officially issued in early 2026 as Annexes III and IV, following the successful issuance in 2023 of Annexes I and II addressing computer program-related inventions. The IP Office recently organized a seminar to gather feedback on the draft annexes from intellectual property representatives, academic institutions, research institutes, and other interested parties, emphasizing its intention to receive further constructive opinions to refine the guidelines for pharmaceuticals and biotechnology. Why These Guidelines Matter Patent examination in Vietnam has traditionally relied on the Guidelines for Patent Examination issued under Decision No. 487/QD-SHTT (2010), recently supplemented by Annexes I and II. While these documents provide a solid foundation, they do not fully address practical challenges in examining pharmaceutical and biotech inventions, particularly issues related to clarity, sufficiency of disclosure, enablement, features of function and utility, combination therapies, and inventions involving artificial intelligence (AI) applications in these fields. Annexes III and IV aim to close these gaps by introducing structured principles and illustrative examples. Guidance on Patent Specification Requirements Annex III provides detailed guidance on the requirements for patent specifications in pharmaceuticals and biotechnology, covering two main parts: Part A addresses sufficiency of disclosure, clarity of specifications, and consistency between claims and descriptions. Part B covers inventions related to Markush-type compounds, claims containing exclusion statements (disclaimers), and additional experimental data submitted during examination. The Guidelines outline specific disclosure requirements for subject matters such as compounds, formulations, pharmaceutical compositions, genes, polypeptides, proteins, vectors, transgenic organisms, modified organisms, and hybrid cells. Annex III emphasizes that disclaimers are not accepted

On December 11, 2025, Vietnam’s National Assembly issued Resolution No. 254/2025/QH15 (Resolution No. 254) to address practical difficulties encountered in implementing the Law on Land 2024. The resolution provides specific mechanisms and policies to resolve issues related to land allocation, land leasing, and conversion of land-use purposes, while also addressing land valuation principles, timing of information collection, and land valuation methods. The resolution takes effect on January 1, 2026. Key provisions affecting investors are discussed below. Land Use Terms for Transferred Investment Projects The National Assembly has addressed situations where the remaining term of a transferred investment project is insufficient for the transferee’s business or financial plans. Resolution No. 254, along with the Law on Investment 2025, introduces aligned regulatory solutions. Under the Law on Investment 2025 (4th version submitted to the National Assembly for promulgation), if an investment project implemented prior to March 1, 2026, has been transferred and the transferor holds a Land Use Rights Certificate, has fulfilled all land-related financial obligations, and is not subject to termination, the competent authority may determine a new operating term if the remaining operating term does not meet the transferee investor’s financial or business plan. This adjustment occurs when approving or adjusting the investment policy or issuing or amending the investment registration certificate. The revised operating term is calculated from the date of the approval or issuance and must not exceed the statutory maximum of 70 years for projects in economic zones and 50 years for projects outside economic zones. Resolution No. 254 also permits adjustment of the land use term for transferred investment projects involving land, provided that the transferee investor pays additional land rent in accordance with applicable law, thereby ensuring consistency with the Law on Investment 2025. Land Rent Payment Options Resolution No. 254 generally expands the

Vietnam’s National Assembly approved wide-ranging amendments to the Intellectual Property (IP) Law on December 10, 2025, marking one of the most significant overhauls of the country’s IP regime in recent years. The changes, which supplement and refine existing provisions, are designed to align Vietnam’s framework more closely with international standards while addressing practical challenges faced by rights holders and practitioners. The amendments will come into force on April 1, 2026. The most notable changes are detailed below. Recognition of partial and nonphysical industrial designs: Industrial design protection has been broadened to cover partial designs and nonphysical forms (class 32), explicitly extending rights to parts of products that are not independently circulated as well as digital and intangible product appearances. The law clarifies that the external appearances of nonphysical products are protected industrial designs, and circulation of digital copies of any part of that appearance will be treated as an act of using the industrial design. The provision on the industrial applicability of industrial designs has also been amended accordingly to include the uniform reproduction of nonphysical products in cyberspace. Resolving conflicts between overlapping rights: The IP Law provides a safeguard against conflicts when a single subject matter is protected by multiple IP rights. Where overlapping rights exist, the later-arising right will be terminated if its exercise interferes with the normal exploitation of an earlier right. The decision to terminate such a later right rests with the court. Use of published data for AI training: Organizations and individuals may use lawfully published and publicly accessible documents and data for scientific research, testing, and AI system training. Such use must not unreasonably prejudice the rights or legitimate interests of authors or IP rights holders. Where the documents and data fall under copyright or related rights protection, their use must also comply
