Actually, it is usually not. Well-known trademarks have a wider scope of protection. A trademark holder may effectively prevent coat tail riding on the basis of its trade mark rights. However, in reality this does not always happen. Supermarket chain LIDL sells licorice under its own trademark BROMMER DROP (which means moped licorice). A name (and packaging), which – probably not coincidentally – is very similar to the well-known AUTO DROP (car licorice). Since this action was rather successful they now introduced VLUGGE JAPIE (Quick Japie), which is conceptually very similar to its competitor. It remains to be seen whether the proprietors of the well-known trademarks will take any action against LIDL. For now it seems LIDL gets away with it.
