The words Certified Genealogist are a registered certification mark with the United States Patent and Trademark Office, and the designations CG and CGL are service marks of BCG, used under license by certificants after periodic competency evaluations (and only during the current five-year period for which they are certified).


BCG has an affirmative obligation to make sure that its marks are used properly, to ensure the legal protection of its rights.

The Board’s Intellectual Property Committee monitors potential infringements of the Board’s registered certification mark (such as improper use of the term “certified genealogist” in a descriptive or generic way), as well as its service marks. It is essential that BCG associates and others use our marks (trademarks and service marks) properly.

Any concerns or questions about an incorrect use should be directed to the office@bcgcertification.org.
