TOP-SIDER case: improper use and cancellation of trademark registration
Japan | 24 June 2019

A recent IP High Court case concerned the cancellation of a trademark registration due to a non-exclusive licensee's improper use of the registered mark. Cases regarding cancellation based on Article 53 of the Trademark Act are rare, and cases in which requests to cancel a trademark registration on this basis are granted are even more so. As such, this case is an interesting example of how the IP High Court determines improper use of a registered trademark.

RED BULL trademarks: determining well-known status and recognising fame
Japan | 19 March 2018

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.

Japan | 04 December 2017

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.

Can you register a parody trademark?
Japan | 19 June 2017

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.

Trademark procedures and strategies
Japan | 01 May 2017

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.
