 | | Trademark owners should never use the trademark as a verb (A word that serves as the predicate of a sentence) or noun (A word that can be used to refer to a person or place or thing), implying the word is generic. |
| | Trademarks, unlike copyright (A document granting exclusive right to publish and sell literary or musical or artistic work) s and patent (An official document granting a right or privilege) s, must be actively used and defended. |
| | One consequence of a trademark becoming generic is that the exclusive right (A right reserved exclusively by a particular person or group (especially a hereditary or official right)) s which may attach to the use or registration of the trademark can no longer be legally enforced. |
