|Note: Trademarked wordmarks are generally not case-sensitive and are listed in uppercase by trademark registrars.
A wordmark or word mark is a distinct text-only typographic treatment of the name of a product, service, company, organization, or institution which is used for purposes of identification and branding. A wordmark can be an actual word (e.g., Apple), a made-up name that reads like a word (e.g., Google), or an acronym, initialism, or a series of letters (e.g., IBM).
Unlike names and logos, trademarked wordmarks are generally not case-sensitive and are listed in uppercase by trademark registrars such as the United States Patent and Trademark Office, even if they are always cased in a certain way by the owner; this gives the trademark holder rights no matter how the wordmark is presented[ citation needed]. Some examples are shown in the sidebar.
In the United States, the legal term "word mark" refers only to the text, not to any graphical representation. 
Wordmarks and logos are the two most common types of brand marks.[ citation needed] Wordmarks, by definition, always contain the name of the product or company, whereas a logo might be a textless image only. For example, the Coca-Cola, Disney, and FedEx logos are graphical versions of those names, while the Starbucks logo contains no text.
A wordmark logo (also called a lettermark or a lettermark logo) is a type of logo, not a type of wordmark, which consists of just text set in a particular style, such as a typeface or color, without other graphical features.[ citation needed] For example, the SONY logo contains only the name in uppercase, set in a particular typeface. In some cases, such as Disney's logo, a custom or proprietary typeface is used.[ citation needed]
