On 26th December, 2024, the Intellectual Property Office issued Notice No. 4031/TB-SHTT regarding the unified application of the International Patent Classification under the Strasbourg Agreement, version 2025.01. Accordingly, the new IPC has been published on the official website of the Intellectual Property Office and officially applied in Vietnam from 1st January, 2025.
From 1st January, 2025, when completing the application form, applicants must use the IPC version 2025.01 to fill the “International Patent Classification” section to specify the classification index of the technical solution to be protected (a complete classification, including section, class, subclass, group (main group or subgroup)). In cases in which applicants fail to classify or incorrectly classify their inventions, the Intellectual Property Office will conduct the classification, and applicants will be required to pay the classification fee as prescribed.
The Intellectual Property Office emphasizes that any difficulties encountered during the implementation process should be promptly reported to the Office through the Industrial Property Information Center for review and resolution.
