A bill to amend the Japan Trademark Act was enacted on June 14, 2023, and the revised law is due to take effect on April 1, 2024. The Japan Patent Office (“JPO”) recently published an overview of the newly introduced “Letter of Consent” system on its website (in Japanese), and is currently accepting public comments on the draft Examination Guidelines until January 24, 2024 (in Japanese).

The JPO has also published a Q&A on the general questions that are expected (in Japanese). Please refer to the following:
