Certified Trademark Attorney
The trademark attorney profession is similar to that of a patent attorney, accountant or sollicitor. Your trademark attorney also handles confidential information and must have sufficient knowledge of trademark law and the case law. A trademark attorney is not a recognised profession. This allows people with insufficient knowledge or experience to call themselves trademark attorney.
The mark BMM Certified Trademark Attorney is a certification mark for trademark attorneys. This quality mark was created by the Benelux Association for Trademark and Design Law (BMM).
The BMM Certified Trademark Attorney label may only be used by BMM members with three years of experience and passed the BMM examination. The BMM quality mark gives consumers and businesses the certainty that the trademark attorney, has the necessary knowledge, training and experience to advise adequately on the examination, registration and enforcement of trademarks and designs. Mr Ivo Haaijer and Mrs. Herma Wiersma are BMM-certified trademark attorneys.
