The German Federal Supreme Court (BGH) determined in its
"Clinique Happy" decision (BGH I ZR 235/10), that
imported counterfeit articles traveling through Germany intended
for sale in a foreign market (so-called "unbroken transit of
custom sealed goods" – zollverschlossene,
ungebrochene Durchfuhr von Waren) are not subject to the
protection of German trade mark law, even if the mark in question
is registered in Germany or the EU. Such marks are not being used
as trade marks pursuant to the German trademark Act during the mere
transport of the articles through Germany to a foreign destination
market. Furthermore, the principle of territoriality foreign
trademark law in connection with German tort law does not grant
protection to marks merely travelling through Germany.
