Representing Mr. Manolo Blahnik in successfully invalidating through retrial proceeding the registration of trademark filed by a Chinese squatter in class 25 in 1999, based on the designer’s name right and the bad faith of the registrant. The case almost exhausted every available remedial route, including opposition, review of opposition and two instances of administrative suits, invalidation, and the ensuing administrative suits, which all failed. The retrial decision turned the table for the client in its decades-long battle against the copycat trademark.
