The JPO has revised the “Trademark Examination Standards” to comply with the revised Trademark Law of 2023.
The basic concepts (including interpretation and operation) of the application of the Trademark Act in the performance of practical duties in trademark examination are summarized in the Trademark Examination Guidelines, which are classified as general guidelines for trademark examination and are broadly used in order to deepen trademark applicants' and their representatives' understanding of the practical duties performed at the JPO.
