A Connecticut Certificate of Registration of a Collective Mark is a legal document that grants exclusive rights to a group of companies or organizations to use a collective mark. This type of registration is available in the United States and is regulated by the United States Patent and Trademark Office (USPTO). The collective mark is a distinctive symbol, logo, or phrase used to represent the common business interests of the members of the group. A collective mark is used to differentiate the goods and services of the members of the group from those of others. There are two types of Connecticut Certificate of Registration of a Collective Mark: one for a “standard” collective mark and one for a “certified collective mark”. A standard collective mark registration grants exclusive rights to the group to use the collective mark in advertising and promotion only. A certified collective mark registration grants exclusive rights to the group to use the collective mark in advertising and promotion, as well as use it as a certification mark to signify compliance with quality or performance standards.
