A Certification Mark is a special type of trademark that indicates a product or service meets certain standards set by an organization. This mark assures consumers that the item has been tested and verified for quality, safety, or performance. Examples of certification marks include the UL Mark for electrical safety and the Energy Star label for energy efficiency. Unlike regular trademarks, which identify the source of goods or services, certification marks are used by multiple businesses that meet the established criteria. The owner of the certification mark, often a non-profit organization or government agency, oversees the certification process to maintain the integrity of the mark.
