Proper Use (Trademark) Law and Legal Definition

A trademark should be properly used to maintain its protectable interest. Marks that are improperly used are subject to claims of genericide and other attacks. To use a mark properly, the trademark owner should perform the particulars such as:

1) use the mark as an adjective of the underlying product rather than as a noun,

2) italicize, underline, capitalize or boldface the mark when it appears in text, in order to set it out from the generic word for the product,

3) affix the mark to the goods or services,

4) provide proper notice of trademark rights.
