The case: Since the 1950s, German publisher Langenscheidt markets dictionaries in a special yellow color. This color is registered as a German trademark for “printed bilingual dictionaries”, on the basis of acquired distinctiveness. Rosetta Stone offered a language-learning software using a specific yellow color. Langenscheidt sued Rosetta Stone for infringement of its yellow color trademark. The German Federal Supreme Court confirmed the infringement.
