Berlin company Einhorn asked a state court in Duesseldorf today to overturn an injunction obtained by a German rival, Fair Squared, barring it from using the claim on packaging.
Lawyers for Einhorn argued that the slogan was obviously a joke but judges indicated they weren't minded to budge, news agency dpa reported.
Presiding Judge Johanna Brueckner-Hofmann said the slogan is "suited to deception" and could tempt people to use the condoms several times. She said "that is why we banned this."
The court will announce its decision on November 26.
