In a recent case, Red Bull AG claimed that a trademark registered by Korean company Bullsone Co, Ltd should be invalidated due to the likelihood of confusion as to the source of the designated goods. A notable point in this case was the difference in position taken by the Japan Patent Office Trial and Appeal Board and the IP High Court with regard to the relevant trademarks and the evidence to be considered when determining the well-known status of the cited mark.
A Japanese company recently claimed that a Chinese company's trademark should be invalidated due to its similarity with the plaintiff's trademarks and the likelihood of confusion as to the source of the designated goods. Although the Japanese Patent Office Trial and Appeal Board rejected the plaintiff's claims, the IP High Court overturned this decision. The conclusive factor in the case was the way in which the similarity of marks should be assessed when they are intended to be stitched on certain goods.
The Tokyo District Court recently rendered its judgment in a patent infringement case regarding fintech-related technologies. This case has been widely reported on in Japan because both parties are major venture businesses and leaders in the Japanese fintech market. This case is also notable as the defendant's cloud-based accounting system involved machine-learning technologies and disputes of this nature are expected to increase.
The registrant in a recent case registered the trademark FRANCK MIURA in Japanese katakana and Chinese characters with regard to its lookalikes of Franck Muller's well-known luxury watches. However, while the watch designs resembled each other in their entirety, the design similarities were not at issue in this case. Rather, the case centred on the similarity of, and the likelihood of confusion between, the trademark and three prior FRANCK MULLER marks.
The Trademark Law and its related regulations govern the registration and protection of trademarks in Japan. The Examination Guidelines for Trademarks also play an important role in the examination of trademark applications at the Japan Patent Office. Revisions to the examination guidelines are underway and additional revisions (eg, guidelines on judging the similarities between trademarks) are under discussion.
