Which type of marks are considered fanciful marks?

Fanciful marks are a specific type of trademark that consist of invented or made-up words that have no prior meaning. These marks are distinct because they do not describe or suggest anything about the product or service they represent. They gain their meaning solely through their association with the brand. For instance, a term like "Google" or "Kodak" does not have any inherent connection to the nature of the services or products they provide, making them quintessential examples of fanciful marks.

The other options suggest different types of marks that do not fit the definition of fanciful. Descriptive marks, for example, convey specific attributes of a product and are not fanciful because they provide information rather than unique branding. Suggestive marks imply qualities that require some imagination from the consumer but are not entirely invented, while common words used in unrelated contexts represent marks that are recognizable but do not fall under the category of fanciful. Thus, the correct identification of fanciful marks as invented words aligns perfectly with their role in trademark law.
