List of former trademarks that have been genericized

The following partial list contains marks which were originally legally protected trademarks, but which have subsequently lost legal protection as trademarks by becoming the common name of the relevant product or service, as used both by the consuming public and commercial competitors.

List of protected trademarks frequently used as generic terms

Marks in this partial list are still legally protected as trademarks, at least in some jurisdictions, but are sometimes used by consumers in a generic sense. Unlike the names in the list above, these names are still widely known by the public as brand names, and are not used by competitors. Scholars disagree as to whether the use of a recognized trademark name for similar products can truly be called “generic”, or if it is instead a form of synecdoche.

The previous list contains trademarks that have completely lost their legal status in some countries, while the following list contains marks which have been registered as trademarks, continue in use, and are actively enforced by their trademark owners. Writing guides such as the AP Stylebook advise writers to “use a generic equivalent unless the trademark is essential to the story”.(K)

Please note that other generic terms may be equally appropriate.
