Based on EU trade mark law, a trade mark registration can be revoked if it has become a common indication as a result of acts or omissions by the trade mark owner. In a recent ruling of the Court of First Instance of the EU Court of Justice, an interesting position was taken regarding trade marks that have become common names. The court ruled that the perception of the end users is the only relevant criterion. Additionally, "omission" is also understood as the omission by the trade mark owner to encourage sellers to make more use of the mark in marketing the respective products.
