Service marks identify and distinguish the source of a service rather than a product.
Certification marks are any word, name, symbol, device, or any combination, used, or intended to be used, in commerce by someone other than its owner, to certify regional or other origin, material, mode of manufacture, quality, accuracy, or other characteristics of such person's goods or services, or that the work or labor on the goods or services was performed by members of a union or other organization.
Collective marks are trademarks or service marks used, or intended to be used, in commerce, by the members of a cooperative, an association, or other collective group or organization, including a mark that indicates membership in a union, an association, or other organization.
