Certified Trademark Attorney

The trademark attorney profession is similar to that of a patent attorney, accountant or sollicitor. After all, your trademark attorney also handles confidential information and you must be able to assume that your attorney has sufficient knowledge of trademark law and the relevant case law. Unlike the aforementioned professions, the Benelux trademark attorney is not a recognised profession. This allows people with insufficient knowledge or experience to still call themselves trademark attorney.

The mark BMM Certified Trademark Attorney is a certification mark of 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 who have at least three years of relevant work experience and who have passed the BMM professional examination. The BMM quality mark gives consumers and businesses the certainty that the trademark attorney, who carries this quality mark, has the necessary knowledge, training and experience to advise adequately on the examination, registration and enforcement of trademarks and designs. Founder of MerkWerk, Mr Ivo Haaijer and Mrs. Herma Wiersma are BMM-certified trademark attorneys.
