Finnegan, Henderson, Farabow, Garrett & Dunner has helped the maker of Vagisil products win a district court judgment blocking a competitor from registering Vagisan in the United States.

Vagisan is marketed in Europe by Germany’s Dr. August Wolff GmbH & Co. The company persuaded the U.S. Patent and Trademark Office to register the mark in 2017. The PTO found that the “Vagi-” prefix is strongly suggestive of an intimate feminine care product, and already used by the likes of Vagitone, Vagifresh and Vagicaine. That overcame the commercial strength of Vagisil’s mark.
